Yes, indeed, with the help from such toy, you can find that to get the sexual satisfaction can be totally easy. You can even have it anytime you want it. You do not need to trouble yourself to find someone who is willing to have sex with you. It means that you will not deal with free sex. Well, actually, to avoid free sex is very necessary since you can also avoid the genital diseases that might come at you. Well, the kinds of the sex toys that you can get are actually highly varied. Of course, the toys can be majorly categorized into two which are the toys for women and the toys for men. Perhaps, you might think that the toys for women are more common. Take the example of how dildo has become so familiar to our ears.

Well, dildo is a kind of penis replica which is used to give the women their sexual pleasure simply by using it. The quality of the satisfaction will be totally great since the dildo is made perfectly similar to the real penis. Thus, the women can feel that they are having real sex. That way the women can also enrich their sexual fantasy by using such toys. Well, normally, the women will prefer to the big dildo since such dildo can give them greater sexual satisfaction.

There are certain exceptions and ways to handle cases where the car doesn’t meet the standard that applies to the particular vehicle type and age. Some vehicles are considered Gross Polluters and are handled as a special case. Vintage cars are also handled differently, since they are a small minority of the total number of vehicles on the road. Smog checking as well as certification is required and many smog check stations having different classifications are found throughout the state. A smog test only station is one that limits its service to only checking adherence to the regulations. Different classes of smog check stations can perform testing and also do repairs on most vehicles, though certain exceptions exist. Special stations like Gold Shield and Referee stations perform other special functions in special cases and if any disputes arise. Low-cost smog check stations like smog check San Francisco, are located in the Bay Area and in other major California metropolitan areas.

Wind power is growing at the rate of 30 percent annually, with a worldwide installed capacity of 121,000 megawatts (MW) in 2008, and is widely used in European countries and the United States. The annual manufacturing output of the photovoltaics industry reached 6,900 MW in 2008, and photovoltaic (PV) power stations are popular in Germany and Spain. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18 percent of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

While most renewable energy projects and production is large-scale, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development. Kenya has the world’s highest household solar ownership rate with roughly 30,000 small (20–100 watt) solar power systems sold per year.

Some renewable-energy technologies are criticized for being intermittent or unsightly, yet the renewable-energy market continues to grow. Climate-change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable-energy legislation, incentives and commercialization. New government spending, regulation and policies should help the industry weather the 2009 economic crisis better than many other sectors.

Main forms/sources of renewable energy

The majority of renewable energy technologies are powered by the sun. The Earth-Atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation, the resulting level of energy within the Earth-Atmosphere system can roughly be described as the Earth’s “climate.” The hydrosphere (water) absorbs a major fraction of the incoming radiation. Most radiation is absorbed at low latitudes around the equator, but this energy is dissipated around the globe in the form of winds and ocean currents. Wave motion may play a role in the process of transferring mechanical energy between the atmosphere and the ocean through wind stress. Solar energy is also responsible for the distribution of precipitation which is tapped by hydroelectric projects, and for the growth of plants used to create biofuels.

Renewable energy flows involve natural phenomena such as sunlight, wind, tides and geothermal heat, as the International Energy Agency explains:

Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Each of these sources has unique characteristics which influence how and where they are used.

Wind power

Vestas V80 wind turbines

Airflows can be used to run wind turbines. Modern wind turbines range from around 600 kW to 5 MW of rated power, although turbines with rated output of 1.5–3 MW have become the most common for commercial use; the power output of a turbine is a function of the cube of the wind speed, so as wind speed increases, power output increases dramatically. Areas where winds are stronger and more constant, such as offshore and high altitude sites, are preferred locations for wind farms. Typical capacity factors are 20-40%, with values at the upper end of the range in particularly favourable sites.

Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand. This could require large amounts of land to be used for wind turbines, particularly in areas of higher wind resources. Offshore resources experience mean wind speeds of ~90% greater than that of land, so offshore resources could contribute substantially more energy. This number could also increase with higher altitude ground-based or airborne wind turbines.

Wind power is renewable and produces no greenhouse gases during operation, such as carbon dioxide and methane.

Water power

Energy in water (in the form of kinetic energy, temperature differences or salinity gradients) can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy.

There are many forms of water energy:

Hydroelectric energy is a term usually reserved for large-scale hydroelectric dams. Examples are the Grand Coulee Dam in Washington State and the Akosombo Dam in Ghana. Micro hydro systems are hydroelectric power installations that typically produce up to 100 kW of power. They are often used in water rich areas as a Remote Area Power Supply (RAPS). There are many of these installations around the world, including several delivering around 50 kW in the Solomon Islands. Damless hydro systems derive kinetic energy from rivers and oceans without using a dam. Ocean energy describes all the technologies to harness energy from the ocean and the sea: Marine current power. Similar to tidal stream power, uses the kinetic energy of marine currents Ocean thermal energy conversion (OTEC) uses the temperature difference between the warmer surface of the ocean and the colder lower recesses. To this end, it employs a cyclic heat engine. OTEC has not been field-tested on a large scale. Tidal power captures energy from the tides. Wave power uses the energy in waves. Wave power machines usually take the form of floating or neutrally buoyant structures which move relative to one another or to a fixed point. Osmotic power or salinity gradient power, is the energy retrieved from the difference in the salt concentration between seawater and river water. Reverse electrodialysis (PRO) is in the research and testing phase. Vortex power is generated by placing obstacles in rivers in order to cause the formation of vortices which can then be tapped for energy. Solar energy

Monocrystalline solar cell

In this context, “solar energy” refers to energy that is collected from sunlight. Solar energy can be applied in many ways, including to:

Generate electricity using photovoltaic solar cells. Generate electricity using concentrating solar power. Generate electricity by heating trapped air which rotates turbines in a Solar updraft tower. Generate hydrogen using photoelectrochemical cells. Heat water or air for domestic hot water and space heating needs using solar-thermal panels. Heat buildings, directly, through passive solar building design. Heat foodstuffs, through solar ovens. Solar air conditioning Biofuel

Plants use photosynthesis to grow and produce biomass. Also known as biomatter, biomass can be used directly as fuel or to produce biofuels. Agriculturally produced biomass fuels, such as biodiesel, ethanol and bagasse (often a by-product of sugar cane cultivation) can be burned in internal combustion engines or boilers. Typically biofuel is burned to release its stored chemical energy. Research into more efficient methods of converting biofuels and other fuels into electricity utilizing fuel cells is an area of very active work.

Liquid biofuel Information on pump, California.

Liquid biofuel is usually either a bioalcohol such as ethanol fuel or an oil such as biodiesel or straight vegetable oil. Biodiesel can be used in modern diesel vehicles with little or no modification to the engine. It can be made from waste and virgin vegetable and animal oils and fats (lipids). Virgin vegetable oils can be used in modified diesel engines. In fact the diesel engine was originally designed to run on vegetable oil rather than fossil fuel. A major benefit of biodiesel use is the reduction in net CO2 emissions, since all the carbon emitted was recently captured during the growing phase of the biomass. The use of biodiesel also reduces emission of carbon monoxide and other pollutants by 20 to 40%.

In some areas corn, cornstalks, sugarbeets, sugar cane, and switchgrasses are grown specifically to produce ethanol (also known as grain alcohol) a liquid which can be used in internal combustion engines and fuel cells. Ethanol is being phased into the current energy infrastructure. E85 is a fuel composed of 85% ethanol and 15% gasoline that is sold to consumers. Biobutanol is being developed as an alternative to bioethanol.

Another source of biofuel is sweet sorghum. It produces both food and fuel from the same crop. Some studies have shown that the crop is net energy positive ie. it produces more energy than is consumed in its production and utilization.

Solid biomass Sugar cane residue can be used as a biofuel

Solid biomass is most commonly used directly as a combustible fuel, producing 10-20 MJ/kg of heat. Its forms and sources include wood fuel, the biogenic portion of municipal solid waste, or the unused portion of field crops. Field crops may or may not be grown intentionally as an energy crop, and the remaining plant byproduct used as a fuel. Most types of biomass contain energy. Even cow manure still contains two-thirds of the original energy consumed by the cow. Energy harvesting via a bioreactor is a cost-effective solution to the waste disposal issues faced by the dairy farmer, and can produce enough biogas to run a farm.

With current technology, it is not ideally suited for use as a transportation fuel. Most transportation vehicles require power sources with high power density, such as that provided by internal combustion engines. These engines generally require clean burning fuels, which are generally in liquid form, and to a lesser extent, compressed gaseous phase. Liquids are more portable because they can have a high energy density, and they can be pumped, which makes handling easier.

Non-transportation applications can usually tolerate the low power-density of external combustion engines, that can run directly on less-expensive solid biomass fuel, for combined heat and power. One type of biomass is wood, which has been used for millennia. Two billion people currently cook every day, and heat their homes in the winter by burning biomass, which is a major contributor to man-made climate change global warming. The black soot that is being carried from Asia to polar ice caps is causing them to melt faster in the summer. In the 19th century, wood-fired steam engines were common, contributing significantly to industrial revolution unhealthy air pollution. Coal is a form of biomass that has been compressed over millennia to produce a non-renewable, highly-polluting fossil fuel.

Wood and its byproducts can now be converted through processes such as gasification into biofuels such as woodgas, biogas, methanol or ethanol fuel; although further development may be required to make these methods affordable and practical. Sugar cane residue, wheat chaff, corn cobs and other plant matter can be, and are, burned quite successfully. The net carbon dioxide emissions that are added to the atmosphere by this process are only from the fossil fuel that was consumed to plant, fertilize, harvest and transport the biomass.

Processes to harvest biomass from short-rotation trees like poplars and willows and perennial grasses such as switchgrass, phalaris, and miscanthus, require less frequent cultivation and less nitrogen than do typical annual crops. Pelletizing miscanthus and burning it to generate electricity is being studied and may be economically viable.

Biogas

Biogas can easily be produced from current waste streams, such as paper production, sugar production, sewage, animal waste and so forth. These various waste streams have to be slurried together and allowed to naturally ferment, producing methane gas. This can be done by converting current sewage plants into biogas plants. When a biogas plant has extracted all the methane it can, the remains are sometimes more suitable as fertilizer than the original biomass.

Alternatively biogas can be produced via advanced waste processing systems such as mechanical biological treatment. These systems recover the recyclable elements of household waste and process the biodegradable fraction in anaerobic digesters.

Renewable natural gas is a biogas which has been upgraded to a quality similar to natural gas. By upgrading the quality to that of natural gas, it becomes possible to distribute the gas to the mass market via the existing gas grid.

Geothermal energy

Krafla Geothermal Station in northeast Iceland

Geothermal energy is energy obtained by tapping the heat of the earth itself, both from kilometers deep into the Earth’s crust in some places of the globe or from some meters in geothermal heat pump in all the places of the planet . It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from heat in the Earth’s core.

Three types of power plants are used to generate power from geothermal energy: dry steam, flash, and binary. Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually at temperatures over 200 °C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators and then runs the steam through a turbine. In binary plants, the hot water flows through heat exchangers, boiling an organic fluid that spins the turbine. The condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat.

The geothermal energy from the core of the Earth is closer to the surface in some areas than in others. Where hot underground steam or water can be tapped and brought to the surface it may be used to generate electricity. Such geothermal power sources exist in certain geologically unstable parts of the world such as Chile, Iceland, New Zealand, United States, the Philippines and Italy. The two most prominent areas for this in the United States are in the Yellowstone basin and in northern California. Iceland produced 170 MW geothermal power and heated 86% of all houses in the year 2000 through geothermal energy. Some 8000 MW of capacity is operational in total.

There is also the potential to generate geothermal energy from hot dry rocks. Holes at least 3 km deep are drilled into the earth. Some of these holes pump water into the earth, while other holes pump hot water out. The heat resource consists of hot underground radiogenic granite rocks, which heat up when there is enough sediment between the rock and the earths surface. Several companies in Australia are exploring this technology.

The property of an object or a system (a group of objects) which enables it to do work is called energy. You need energy to do work, or to apply a force across a distance, meaning to move something. If energy does involve moving an object, it is called kinetic energy. A ball rolling downhill has kinetic energy. Energy can also come from the position of an object or its arrangement. This type of energy is called potential energy, or stored energy. A ball that is stationary, on the slope of a hill, before it begins to roll down, has what is known as gravitational potential energy. As the ball rolls downhill, the potential energy it had is changed into kinetic energy. That is an example of the law of energy conservation; energy cannot be created or destroyed, it changes form from one type to another.

]]>

 Since energy does change from one form to another, sometimes it is difficult to determine whether energy is potential or kinetic. Some energy is potential energy and kinetic energy simultaneously, such as thermal energy, or heat. Even a moving object can have both potential energy and kinetic energy at the same time. As the ball rolls downhill, its potential energy is changed into kinetic energy. As it rolls, at any specific time, the total amount of energy that the ball has does not change; the law of energy conservation holds. This type of energy is considered mechanical energy.

When teaching kids about energy it’s important to relay that besides the motion of objects, other types of kinetic energy include radiant energy, or light; radiant heat energy; acoustic energy, or sound; and electrical energy, or electricity through wires. Other types of potential energy include electrical energy stored in a battery, chemical energy, nuclear energy, magnetic energy, and solar energy; all stored energy in atoms or molecules. Elastic energy is potential energy within a fluid or solid that can be converted into mechanical energy.

Can there ever be a perpetual motion machine? That is, a machine that never stops moving and constantly creates its own energy as it works? Most machines noticeably heat up as they operate. This heat is from friction. The energy that goes into a machine is always greater than the amount of work it produces, because some of the initial energy changes into friction. Because friction is never completely eliminated, the energy going into a machine is always going to be larger than the machines output. A machine can never run indefinitely, so a perpetual motion machine cannot exist.

When teaching kids about energy you can explain the different types of energy. Energy is either kinetic, involving motion, or potential, stored. Energy changes form from one to another, leading to the law of energy conservation. Energy cannot be created or destroyed, it transforms from one type to another type. A perpetual motion machine cannot exist, since such a device would counteract the law of energy conservation.

Energy is a fascinating and vast subject but by remembering these energy basics teaching kids about energy can be simple and fun.

            There is also emphasis on building about 20000 mw of solar capacity by 2020. There are few listed players providing the technology (photovoltaic power systems, etc) required for generating power from solar energy. Companies like Webel SL Energy, Moser Baer and XL Telecom are the known listed companies. Others like Euro Multivision recently came out with an IPO. Webel has increased its generation capacity to about 100 mw currently from 42 mw in FY08. However, it still generates a large part of its revenue from foreign markets.

Nearly 55 per cent of the State’s population depends on agriculture for its livelihood. This sector has been the single largest provider of employment to the rural people of the State. However, the contribution of agriculture sector in the State economy is reducing over the period because of unfavorable agro-climatic situation and faster growth in other sectors especially in services sector. Nearly, one-third area of the State falls under rain-shadow region, where the rains are scanty and erratic. In these areas, only dry land cultivation is undertaken. Out of the total geographical area of the state, the proportion of area under agriculture (56.8 per cent in 2005-06) is much more than that at national level (43.2 percent). Despite huge spending on the irrigation projects, the proportion of gross area irrigated to gross cropped area in the state is around 17 percent as against about 43 per cent at the national level. Most of the electricity in Maharashtra state comes from fossil-fuels like coal, oil and natural gas.

 Today the demand of electricity in Maharashtra state is increasing where as the reserves of the fossil-fuel are depleting every day. The demand of electricity is already more than the production of electricity. We can feel this fact from the electricity-cuts during summer. Luckily Sun throws large amount of energy over Maharashtra state, that if we can trap few minutes of solar energy then it is possible to supply electricity for whole year to India. Most parts of India get 7 KWH/ sq-meter of energy per day averaged over a year The use of photovoltaic (PV) power to run irrigation systems was encouraged several years ago by various governments and international agencies, but this was less successful than expected, partly because of high costs. As solar home systems are becoming more established and there is increasing local technical support for PV technology, the use of PV for irrigation is increasing as well. Solar power systems collect energy from sunlight; thermal systems convert it to heat, while PV systems convert it to electricity. The amount of energy produced varies according to the system’s location, the time of year and the weather, although some energy is produced even on cloudy days.

Average isolation showing land area (small black dots) required to replace the world primary energy supply with solar electricity. Isolation for most people is from 150 to 300 W/m² or 3.5 to 7.0 kWh/m²/day. Solar energy refers primary to the use of solar radiation for practical ends. However, all renewable energies, other than geothermal and tidal, derive their energy from the sun.   The benefits of off-grid solar PV in developing countries include the avoidance of fire risk and pollution from kerosene lamps, the ability to charge mobile phones, and the provision of radio, television and computer services.

The existence of the photovoltaic effect was shown by physicist Becquerel in 1839. By 1870, Professor W. Grylls Adams experimented on the effect of light on selenium, verifying that a flow of electricity was created, that was called “photoelectric”. By 1885, Charles Fritts built the first photoelectric module, showing evidence of the direct conversion of sunlight energy into electric energy. In 1921 Albert Einstein won the Nobel Prize for explanatory theories on photovoltaic effect. In 1953, executives from Bell presented the so-called Solar Battery Bell, showing a panel of photovoltaic cells that powered a miniature Ferris wheel. Within a few years, selenium was replaced by silicon as the basic material for the cells.

Among the renewable sources of energy, solar energy has a huge potential for power generation in Maharashtra. There are 250-300 days of clear sun with an available average radiation of 4 to 6 kWh/m²over a day. There is a capacity to generate 1.5 million units/MW/year through solar photovoltaic systems & up to 2.5 million units/MW/ year through solar thermal systemsaharatra is already in process to boost this enormous source and interested solar project developers can submit their proposals to MEDA. Solar energy can supply and/or supplement many farm energy requirements. The following is a brief discussion of a few applications of solar energy technologies in agriculture. For more information, you may wish to consult the publications listed below. Depending on location, a 1 kW system can produce from 1,400 kWh to 2,000 kWh per year. Watts are units of power measured over one second. If one watt of electric power is used per hour, the total volume of power consumed is expressed as one watt hour, or 1Wh. Similarly, 1,000 watts of power is expressed as one kilowatt (1kW) and 1,000 watt hours as one kilowatt hour (1kWh). If a 2kW system produces power continuously for five hours, the total volume of power generated is expressed as 10kWh.

As sun through large amount of energy in Maharashtra state, using the sun to dry crops and grain is one of the oldest and most widely used applications of solar energy. The simplest and least expensive technique is to allow crops to dry naturally in the field, or to spread grain and fruit out in the sun after harvesting. The disadvantage of these methods is that the crops and grain are subject to damage by birds, rodents, wind, and rain, and contamination by windblown dust and dirt. More sophisticated solar dryers protect grain and fruit, reduce losses, dry faster and more uniformly, and produce a better quality product than open-air methods.

The basic components of a solar dryer are an enclosure or shed, screened drying trays or racks, and a solar collector. In hot, arid climates the collector may not even be necessary. The southern side of the enclosure itself can be glazed to allow sunlight to dry the material. The collector can be as simple as a glazed box with a dark colored interior to absorb the solar energy that heats air. The air heated in the solar collector moves, either by natural convection or forced by a fan, up through the material being dried. The size of the collector and rate of airflow depends on the amount of material being dried, the moisture content of the material, the humidity in the air, and the average amount of solar radiation available during the drying season.

Livestock and dairy operations often have substantial air and water heating requirements. Modern pig and poultry farms raise animals in enclosed buildings, where it is necessary to carefully control temperature and air quality to maximize the health and growth of the animals. These facilities need to replace the indoor air regularly to remove moisture, toxic gases, odors, and dust. Heating this air, when necessary, requires large amounts of energy. With proper planning and design, solar air/space heaters can be incorporated into farm buildings to preheat incoming fresh air. These systems can also induce or increase natural ventilation levels during summer months. Solar water heating systems can provide low to medium temperature hot water for pen cleaning. Commercial dairy farms use large amounts of energy to heat water to clean equipment, as well as to warm and stimulate cows’ udders. Heating water and cooling milk can account for up to 40% of the energy used on a dairy farm. Solar water heating systems may be used to supply all or part of these hot water requirements.

Another agricultural application of solar energy is greenhouse heating. Commercial greenhouses typically rely on the sun to supply their lighting needs, but are not designed to use the sun for heating. They rely on gas or oil heaters to maintain the temperatures necessary to grow plants in the colder months. Solar greenhouses, however, are designed to utilize solar energy for both heating and lighting. A solar greenhouse has thermal mass to collect and store solar heat energy, and insulation to retain this heat for use during the night and on cloudy days. A solar greenhouse is oriented to maximize southern glazing exposure. Its northern side has little or no glazing, and is well insulated. To reduce heat loss, the glazing itself is also more efficient than single-pane glass, and various products are available ranging from double pane to “cellular” glazing. A solar greenhouse reduces the need for fossil fuels for heating. A gas or oil heater may serve as a back-up heater, or to increase carbon dioxide levels to induce higher plant growth.

Solar electric, or photovoltaic (PV), systems convert sunlight directly to electricity. They can power an electrical appliance directly, or store solar energy in a battery. A “remote” location can be several miles or as little as 50 feet (15 meters) from a power source. PV systems may be much cheaper than installing power lines and step down transformers in applications such as electrical fencing, lighting, and water pumping.

Photovoltaic (PV) water pumping systems may be the most cost-effective water pumping option in locations where there is no existing power line. When properly sized and installed, PV water pumps are very reliable and require little maintenance. The size and cost of a PV water pumping system depends on the local solar resource, the pumping depth, water demand, and system purchase and installation costs. Although today’s prices for PV panels make most crop irrigation systems too expensive, PV systems are very cost effective for remote livestock water supply, pond aeration, and small irrigation systems.

 First objective of this is to provide energy for cooking, electricity and motive power through various forms of locally available biomass materials with energy production & distribution to be managed by local communities. Second objective is to envisage energy plan which includes assessment of total demand, resource availability and an appropriate technology mix to meet demand.

Village Energy Security Programme was launched by Ministry of Non-conventional Energy Sources (MNES), New Delhi of Govt. of India in the year 2004-05. The programme is planned in such a manner that it should facilitate households of those remote villages / hamlets which still do not have excess to conventional energy sources and will not be electrified by conventional sources till 2012. It has immense social aspect in development of nation as it will provide total energy security (Electricity, Cooking, Motive Power etc) to the villagers to make them self-sufficient.Under village energy security programme (VESP) the exercise of identification of those un-electrified villages which are not feasible to be connected through the grid are considered as ‘remote’ villages. A detailed survey of the remote villages is to be undertaken keeping in view the feasibility and viability of alternatives for biomass gasification / biofuel base power generation, improved  chullha / biogas plants for cooking energy etc. In general villages between minimum 25 households and maximum 200 households can be considered as potential village under VESP. The main and the foremost objective of this programme is the concrete participation of villagers that to in-particular women’s participation by the formation of Village Energy Committee (VEC). The Programme envisages some contribution towards total project cost from respective state governments / beneficiary.

Village Energy Security Programme (VESP) is the programmers launched by Ministry of Non-conventional Energy Sources (MNES), New Delhi keeping in view to make a particular census village or a hamlet of census village self sufficient from the point of view of Energy requirements using locally available renewable energy sources & full participation of local community.

Agricultural technology is changing rapidly. Farm machinery, farm buildings, and production facilities are constantly being improved. You should consider these factors when purchasing and installing a solar system. Payback periods may be shortened by the multiple use of a solar system, such as for space heating and crop drying.
Solar energy is an excellent alternative energy source because there is no pollution generated while it is being used so we actually reduce pollution with every watt of power generated from the sun. Even if we can’t reduce how much energy is used we should at least control where that energy comes from.
There is no cost involved with using solar power other that the cost of manufacturing the components, purchasing and installation. After your initial investment there is no further cost associated with its use.
Solar energy systems are flexible and expandable. This means that your first solar project can be a small one and you can expand your solar electric system to meet your needs by installing more panels. By starting with a small project you can avoid a major investment up front.
As our use of solar energy increases, our demand on fossil fuels decreases. This will extend the time before our supply of fossil fuels (oil and natural gas etc…) expires or costs become so high only the rich can afford them.
There is no pollution associated with the use of solar power. No smoke stacks pumping greenhouse gasses into the air means less pollution.
A solar electric system installed in a home could potentially eliminate 18 tons of greenhouse gas emissions from the environment each year.
Using solar energy is a silent process. No noise pollution.
With space heating appliances using fossil fuels there is always the risk of a cracked heat exchanger, which can cause CO2 poisoning (Carbon Dioxide). This is not a problem when using solar energy.
A great advantage of solar is for remote applications. It is the best way to supply electricity to isolated places in the world where the cost associated with installing power distribution lines makes it impractical or impossible.
Solar energy can be used to heat water and for space heating.
You can build your own system from collecting the parts required or purchase one of the many solar kits that are available. Using kits takes a lot of the work out of building your own system.

A building’s location and surroundings play a key role in regulating its temperature and illumination. For example, trees, landscaping, and hills can provide shade and block wind. In cooler climates, designing buildings with an east-west orientation to increase the number of south-facing windows minimizes energy use, by maximizing passive solar heating. Tight building design, including energy-efficient windows, well-sealed doors, and additional thermal insulation of walls, basement slabs, and foundations can reduce heat loss by 25 to 50%.

Modern building practices often demonstrate little regard for energy efficiency or the larger economic, environmental or social impacts of the built environment. Green building attempts to break with these practices. Early efforts to bring change to the building sector in the 1960s through the 1980s generally focused on single issues such as energy efficiency and conservation of natural resources. Green building now integrates a wide range of building design, construction, and operation and maintenance practices to provide healthier living and working environments and minimize environmental impacts. Crucial to the success of green building has been the application of integrated design principles, a whole-building-systems approach, which brings together the key stakeholders and design professionals as a core team to work collaboratively from the early planning stages through to the building’s occupation.

More important for chemistry is the potential energy of one charge near another charge. The Coulomb potential energy of a charge q 1 at a distance r from a charge q2 is given by q1 q2 /4??0 r, where ?0 is a fundamental constant called the vacuum permittivity. Energy is also stored in the electromagnetic field in the form of photons. The energy of a photon of radiation of frequency ? is hv, where h is Planck’s constant. Energy is conserved; that is, the sum of the kinetic and potential energies of a single body remains constant provided it is free of external influences (forces). Thus, a falling weight accelerates: The fall implies a reduction of potential energy and the acceleration implies an increase in kinetic energy; the sum, though, is constant.

A generalization (which can be interpreted as an implication) of the conservation of energy is the first law of thermodynamics, which focuses on a property of a many-body system called the internal energy. The internal energy can be interpreted as the sum of all the kinetic and potential energies of all the particles comprising the system. The first law of thermodynamics states that the internal energy of an isolated system is constant. The first law is closely related to the conservation of energy, but it acknowledges the possibility of the transfer of energy as heat, which is outside the reach of mechanics itself. The special theory of relativity states that the mass of a body is a measure of its energy: E = mc2, where c is the speed of light. That is, energy and mass are equivalent and interconvertible. Changes in mass are measurable only when changes in energy are considerable, which in practice commonly means for nuclear processes.

In chemistry we are often concerned with the transfer of energy from one location (e.g., a reaction vessel) to another (the surroundings of that vessel). One mode of transfer is by doing work. For example, work is performed when gases evolved in a reaction push back a movable wall (e.g., a piston) against an opposing force, such as that due to the external atmosphere or a weight to which the piston is attached. Another mode of transfer is as heat. Heat is the transfer of energy that occurs as a result of a temperature difference between a system and its surroundings when the two are separated by a diathermic wall (a wall that allows the passage of energy as heat). A metal wall is diathermic; a thermally insulated wall is not diathermic. Finally, energy may leave a system as electromagnetic radiation, for example as in chemiluminescence—the emission of radiation from matter in energetically excited molecular states produced in the course of a chemical reaction, and as a result of spectroscopic transitions. We may concentrate on the first two modes of transfer, work and heat.

At a molecular level, work is the transfer of energy that makes use of or drives the orderly motion of molecules in the surroundings. The uniform motion of the atoms in a piston driven back by expanding gas is an example of orderly molecular motion. In contrast, heat is the transfer of energy that makes use of or causes disorderly motion in the surroundings. When we say that a chemical reaction gives out heat, we mean that energy is leaving the reaction vessel and stimulating thermal motion (random molecular motion) in the surroundings.

The energy of a chemical system is stored in the potential and kinetic energies of the electrons and atomic nuclei. This stored energy is sometimes referred to as chemical energy; however, this is only a shorthand way of referring to the kinetic and potential energies of all the particles in an element or compound. The internal energy of a system changes when a chemical reaction occurs because the electrons and nuclei settle into different arrangements, as in the change of partnerships of H and O atoms in the reaction 2H2(g) + O2(g) ? 2H2O(g). The energy released in a chemical reaction can be transferred to the surroundings (and put to use) in a variety of ways regardless of the manner in which the energy accumulated in the first place. Thus, energy may escape as heat and be used to raise the temperature of the surroundings, including raising the temperature of water that is then employed in a turbine to do work. The energy may also escape as work. The work may be accomplished electrically, as when electrons are driven through an external circuit and used to drive an electric motor.

Atomic nuclei are also centers of energy storage as a result of their internal structures. This energy is released when the nucleons (protons and electrons) undergo rearrangement and thereby change the strength of their interactions. The changes in energy are so great that they give rise to measurable changes of mass. For all chemical processes, the changes in mass accompanying acquisition or loss of energy are totally negligible. 

Modern societies rely on a variety of energy sources to heat homes, propel transportation vehicles, and produce goods for shelter, food, health care, and entertainment. Some of these sources are renewable, whereas others are nonrenewable. A renewable energy source, for example, solar energy, is one that is virtually inexhaustible on the human time scale. A nonrenewable energy source, for example, natural gas, is one that can be either completely consumed (during a lifetime or during several lifetimes) or depleted to such an extent that it is no longer economical for humankind to obtain it. About 80 percent of commercial energy is obtained from three kinds of fuel: oil, coal, and natural gas. When these fuels burn in air they release energy. They are called fossil fuels because they are believed to have formed from the remains of plants and animals subject to heat and pressure for millions of years.

Natural gas is a mixture of methane (CH4), 60 to 90 percent, and smaller amounts of other gaseous hydrocarbons, including ethane (C2H6), propane (C3H8), and butane (C4H10). It is valued because it burns hotter and produces less air pollution than other fossil fuels. Complete combustion of a hydrocarbon substance produces carbon dioxide and water. It has been estimated that in 2001, 2.39 trillion cubic meters of natural gas were consumed worldwide, with estimated remaining reserves of 150 trillion cubic meters.

Oil (also referred to as petroleum) is a complex liquid mixture of organic substances, principally of hydrocarbons containing five to sixteen carbon atoms. Most crude oil, once removed from a well, is sent by pipeline to a refinery, where it is distilled to separate it into gasoline, heating oil, diesel oil, and asphalt. The use of catalysts during the refining process increases the yield of gasoline.  

Coal is the most plentiful fossil fuel, comprising 80 percent of the fuel reserves of the United States and 90 percent of those of the world. It is a complex mixture of organic compounds and is anywhere from 30 to 95 percent carbon by mass. It also contains sulfur compounds. When coal is burned, the sulfur is converted to sulfur dioxide, a troublesome air pollutant. The description of coal as being of high quality is based on its having a low sulfur content and high carbon content. Lignite coal (brown coal) has low carbon content and produces the least energy upon combustion (about 15 kJ/g). Bituminous coal (soft coal) has higher carbon content and produces more energy. It is the most extensively used coal. Anthracite coal (hard coal) has the highest carbon and heat content (about 30 kJ/g), but supplies of it are limited in most places. In 2001, 4.41 billion metric tons of coal was consumed worldwide, with estimated reserves of 985 billion metric tons. (A metric ton is 1,000 kilograms [2,679 pounds].)

The combustion of fossil fuels produces carbon dioxide gas, a heat-trapping gas. For the past 250 years (since the beginning of the Industrial Revolution), the increased use of fossil fuels has caused the atmospheric concentration of carbon dioxide to increase by a factor of about 25 percent. It is now generally believed that this increase has produced higher global temperatures—a phenomenon called the greenhouse effect.

Commercial nuclear power is generated by nuclear fission reactions. When slow-moving neutrons strike nuclei of uranium-235 or plutonium-239, these nuclei are split, releasing energy. The energy is used to heat water and drive a turbine, in turn producing electrical energy. Currently nuclear power supplies more than 16 percent of the world’s total electricity.

A typical nuclear reactor utilizes uranium oxide, whose uranium content is approximately 3 percent uranium-235, and 97 percent uranium-238, by mass. During the fission reaction, the uranium-235 is consumed and fission products form. As the amount of uranium-235 decreases and the amounts of fission products increase, the fission process becomes less efficient. At some point, the spent nuclear fuel is removed and stored. Some of the radioactive fission products, because of their radioactivity and long half-lives, must be stored securely for thousands of years. Thus, nuclear waste management poses a tremendous challenge.

Scientists hope to someday use controlled nuclear fusion to produce energy. Nuclear fusion, which involves the coming together of light nuclei to form heavier ones, is the process by which stars generate energy. In order for nuclear fusion to occur, the nuclei must have extremely high temperatures. Research has focused on the fusion of deuterium (hydrogen-2) nuclei and tritium (hydrogen-3) nuclei, a process that requires about 50 million degrees Celsius. The principal renewable energy sources are biomass from crops such as trees and corn, hydropower from flowing rivers, geothermal power from heat stored in Earth, wind energy from the movement of winds, and solar energy from the Sun.

Wood is part of an array of plant matter referred to as biomass that can be burned to produce energy. The combustible substances in biomass are primarily carbohydrates (and of these, primarily cellulose). Cellulose, whose simplest or empirical formula is CH2O, undergoes combustion to form carbon dioxide and water. Wood fuels continue to be used in the rural areas of developing countries. Hydroelectric power is a well-developed energy source. Today, hydropower provides about 19 percent of the world’s electricity supply. Because it is a clean, renewable source of energy, hydropower should continue to serve as a vital energy source.

There has been a rapid growth in the use of wind turbines to generate electricity. In 2001 the amount of electricity generated in this way worldwide corresponded to the amount that would have been obtained from burning 15 million barrels of oil. Although this represents only about 0.05 percent of worldwide energy production in 2001, this fraction will increase. Solar energy is the most significant and promising renewable energy source. Solar energy is converted to electricity by solar cells (also known as photovoltaic cells). A great deal of solar energy is used currently in what is known as passive heating (which can be directly experienced as the heat gain in a greenhouse caused by sunlight). 

With the renewed interest from homeowners and business owners many Americans are now looking into the energy auditing field to start a new career or modify their existing careers. The first question that is usually prompted is “Do I need to be trained or certified?” Surprisingly, there is not currently any government requirement to be certified to conduct an energy audit. However, in order to gain the trust and confidence of potential clients, most find it necessary to get trained and certified in energy auditing — which is a great idea!

Legacy Energy Audit Training

The energy audit industry has historically been comprised of energy auditors that are trained and certified from two companies – RESNET and BPI. Both companies have strong ties to the U.S. government, the Dept of Energy, and Energy Star. The energy audit training programs offered by both companies are very good. Since these energy auditor training programs are primarily designed for engineers, architects, and home trade experts with a history of energy and inspections, some students describe these programs as complicated, extensive, and expensive.

In order to learn all the energy auditing techniques offered in these programs, these companies generally require an apprenticeship training period in addition to a lengthy training program. Graduates from these programs are well prepared to conduct “Advanced” audits with machinery including blower door testing, duct blaster testing, thermal imaging, and other in-depth measuring techniques and practices. Legacy training programs require their graduates to purchase the equipment necessary to conduct an “Advanced” energy audit at an average cost of K-K. In order to be profitable, the equipment cost is then passed on to the homeowner – the going rate for an “advanced” energy audit is between 0 – 0.

]]>

In addition to the lengthy training period and large upfront costs, the time required to conduct an “advanced” energy audit is usually a minimum of six hours on-site with two workers in a high liability environment and another two hours off-site typing up the energy savings report. Considering that an “advanced” energy audit takes an average of 6 hours plus K – K of test equipment to complete – charging the homeowners a fee of 0 – 0 is a minimal cost – however in this economy homeowners bitterly gripe about that minimal cost.

The Problem With Legacy Energy Audit Training

While legacy energy audit training companies continue to develop highly skilled auditors and engineers, the economy continues to decline. Finding clients that are willing to pay and can afford a 0 – 0 energy audit becomes increasingly harder. Until recently there wasn’t a viable solution to this problem. Only through the creation of a new standard in the industry was this problem able to be solved and energy auditors able to once again have lucrative careers making money saving energy.

The Arrival of the Standard Energy Audit

The Energy Audit Institute created a new type of energy audit for the “eco-conscious” market that reduces the need for energy auditors to buy K – K of equipment. At the same time reducing the amount of time required in the consumers residence or facility, thereby lowering the cost of an energy audit to an affordable rate.

How? By removing the advanced auditing techniques such as blower door testing, and duct blasting and other time and money consuming testing. This simplified audit is called a “standard” energy audit. The standard energy audit still finds (on average) 80% of the energy savings of an “advanced” audit but in a fraction of the time. A “standard” energy audit is primarily a visual inspection and focuses on the primary energy wasting elements such as heating, cooling, and lighting. Since these areas consume and waste the most energy it makes sense that the standard energy audit should focus on these items. Another area of focus is tax incentives and rebates from the U.S. government, states, and local energy and gas companies. Since there are many new rebates on items such as insulation, solar screens, radiant barrier, HVAC systems, and water heaters – making sure these areas are clearly identified and explained to the homeowners is critical.

Energy Audit Training – The Solution

While traditional energy auditors from legacy training programs continue to only offer “advanced” energy audits, a new market for low-cost “standard” energy audits has emerged. With an average cost of 0 – 0 per home audit and 1-2 hours of time to complete, this new energy audit continues to gain traction. Considering the average savings found by a “standard” audit is about 0 per year, being able to only pay 0 for the audit becomes realistic and affordable. With the elimination of the K – K costs in equipment by the energy auditor, there is no longer the need to try and pass those charges on to the client. This means energy auditors that conduct “standard” audits are able to be more profitable when starting out.

The “standard” energy audit has created a true win-win in the marketplace between the energy auditor and the client. Standard energy audits are now helping low income families, fixed income retirees, and those the hardest during this economic recession. Finally everyone can get an energy audit and the country as a whole can work together to reduce wasted energy.
