More and more people are becoming conscious about the environment and going for natural energy options. Solar energy is one such option that is simple and economical. Learnt more how to use solar energy from the points mentioned below.

The solar panels located on the house roof capture sun rays. This sets off another panel located on the other side of the home which converts the electricity or current from direct to alternating. This leads to creating of electricity in all the outlets that are there in the house. In case the residents of the house fail to use it immediately, the current is stored for future use.

Using solar energy has benefits on two fronts – financial and environmental.

Financial benefits are created through the reduction of energy bills. People can also garner credits from the local electrical authority. Using solar energy is also said to enhance the real estate value of a residence.

Environmental benefits are created through the reduction of problems related to global warming. It also leads to conservation of fossil fuels. Pollution is also reduced leading to a cleaner air and water.

Ensure that you go through quality instructions while installing solar panels on your own. This will relieve you of stress and also make you feel pleasant about your DIY project. Internet is a good place to start searching for DIY manuals.

We have gone through several guides to present you a good way of building your very own solar panels for energy. Do not hesitate and acquaint yourselves with how to generate solar energy and reduce your energy bills.

Efficient energy use means simply using less energy to provide the same level of service. An example would be insulating a building to use less heating and cooling energy to achieve the same temperature. Another example is installing fluorescent lights and/or skylights instead of incandescent lights to attain the same level of illumination. Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior.

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.

Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides, and geothermal heat—which are renewable (naturally replenished). In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% of global energy consumption and 15% of global electricity generation.

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.

One of 3 Pelamis P-750 Ocean Wave Power machines in the harbor of Peniche, Portugal

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.

What Is Ambit Energy?

Ambit Energy is a direct-selling energy provider that was founded in 2006 by Jere Thompson and Chris Chambless, in Dallas, Texas.

So the key to exploding your Ambit Energy business and turning it into a massive money-making opportunity, is to learn the key of marketing your business online.

There is good news in the wind for environmentalists. Wind turbine capacity has been increasing and the unit cost of power generated by wind energy is expected to drop, much of which is credited to China’s efforts.

The World Wind Energy Association forecasts that by 2020, wind turbine total installed capacity will reach an estimated 1.5 million megawatts worldwide, accounting for 20% of global electricity consumption. This will represent a substantial jump in the role of wind energy in the next decade, where it represented just 1.5% of global electricity consumption in 2008.

Where news of environmental pollution is an issue of concern in China, it is also China that is set to take the lead in the global wind energy revolution, ahead of the United Kingdom or the United States, who have long been its strongest advocates.

It’s a paradox that in the West, proponents of the green movement protest against the very infrastructure that is needed to drive sustainable energy practices. There is a ‘not in my back yard’ mentality. This paradox is not seen in China. China will not only become a global leader in wind energy, but may be an important supplier to fast growing emerging Asian economies, such as Vietnam, Thailand and Indonesia, who themselves have limited development in the wind energy technology sector.

The Chinese government’s firm commitment

The Chinese government regards the development of wind energy as a key priority. At the end of 2008, China overtook India in having the highest installed capacity of wind energy in Asia with a total 12.2GW of total installed capacity versus India’s 9.6GW.

The Chinese wind power equipment manufacturing industry has been attracting the investment from many enterprises. With market capacity of wind power equipment forecasted to reach 32 billion US dollars by 2010, investing in China is important for many foreign enterprises wishing to take advantage of the substantial and rapid build up of wind energy in China.

In addition, overseas turbine companies have made substantial investments in China, in order to comply with an earlier government stipulation requiring at least 70 percent of components to be sourced domestically for use in Chinese wind energy projects.

In order to meet the demands of the growing market, domestic production and technology of wind turbines and components also had to step up. With this accelerated development of manufacturing, China is gearing up to meet both the domestic demands as well as preparing to supply components to the international market.

Key trends in China’s wind energy industry

1. Supply shortage for wind turbines and associated components predicted

The demand for wind turbines and related components in many countries is increasing. Together, the United States, the European Union and China are targeting to have installed capacity of about 400 to 500 gigawatts by 2020.

Only a number of specialised suppliers are able to produce key parts for higher capacity wind turbines however, and demand may overwhelm some suppliers, especially for those specialising in gearboxes and bearings. In addition, other industries also use similar wind turbine components for their equipment and machinery.

As an emerging technology, wind turbine designs are still evolving. Parts made are mostly customised and non-interchangeable, making replacement suppliers hard to find. Moreover, the advanced technology required to enter the wind turbine industry is a barrier for new entrants.

Currently, most Chinese wind turbines and components for higher-megawatt products are licensed or jointly developed with overseas players, whilst local manufacturers still lack the independent capacity to build higher wattage turbines. With fewer players supplying the higher-megawatt products, there are bottlenecks affecting the supply shortage for wind turbine related equipment, particularly with the government’s emphasis on higher wattage turbines.

Price volatility for raw materials, notably steel, copper and carbon, is a critical factor in some of the wind turbine parts. Steel is used in towers, gearboxes and rotors; copper used in generators and carbon in rotor blades. Any price volatility can result in bottlenecks in the supply chain.

2. More partnerships amongst wind turbine industry players

In order for foreign players to ease their market entry and secure consistent supplies and services, partnerships in the form of mutual agreements, joint ventures or acquisitions between market players; such as wind farm developers or operators, wind turbine manufacturers and wind turbine component manufacturers, will continue. Through such ventures, local players will in turn get to secure proprietary technology.

Examples include Shanghai Electric’s joint effort with German Aerodyn, and Zhejiang Windey’s partnership with Garrad Hassan and Partners Ltd (GH) from the United Kingdom.

3. Local technological advancement

Due to market regulation in China that favours locally made products, foreign players wanting to enter China need to work with local Chinese companies. This in turn, promotes technology transfer amongst Chinese companies and builds local expertise.

An example of this is Sinovel’s joint program with Austria Windtec. Sinovel is developing a three megawatt double feedback, variable shift and constant frequency wind turbine system, the first high-tech Chinese offshore wind turbine system, which will be installed in the first offshore wind farm, the Shanghai Donghai Bridge Wind Farm.

4. China as a major supply chain centre within wind energy industry

If current trends persist, China will become an important global supplier for the wind energy market, especially in key wind turbine components and services. High local demand, China’s strategic location to supply Asian markets with parts and equipments, coupled with development of local research and development skills may encourage a future role as a global wind energy hotspot for services and equipment.

China’s increasing ability to manufacture more affordable wind power equipment might even push South East Asia’s wind energy utilization, especially for small to medium scale projects. While the Chinese government is actively promoting the production of turbines with capacities of over two megawatts, Chinese suppliers are still catching up to the technology. For now, their strength will continue to be in small to medium scale wind energy projects, which are a good fit for South East Asia markets.

5. China wind energy suppliers go global

Chinese suppliers’ interest in European companies may be of strategic geographical importance in the long term.

Chinese market leader Goldwin has acquired majority share of German Vensys in order concentrate on the development of its direct drive wind turbine technology. After the acquisition of Vensys, Goldwind also bought the subsidiary companies that produced converters and variable propeller systems for Vensys, through Vensys in Germany.

For Goldwin, this ensures a local foothold in Europe with spin-off benefits both in Germany as well as in China. It has also absorbed a number of cross-border talent with management experience in the domestic and international markets from companies such as Shenzen

Huawei, Motorola, General Electric, the bearings industry SKF, Siemens and ABB.

China has been described as the world’s factory. In wind energy, the global environment would be the benefactor of its manufacturing prowess.

One of the most exciting forms of renewable energy that shows the most promise is wind energy. Derived from wind turbines, wind energy generates electricity without the need for fossil fuels and the consumption of water, and produces no emissions during the process. This significant environmental benefit makes wind energy one of the most promising and fastest developing forms of renewable energy today.

At the forefront of wind energy development is the state of Texas, known for its oil and natural gas production facilities, but now leads the nation in the production of wind energy. The state can generate Texas electricity using wind energy with a capacity that is three times as much as Iowa, the second highest wind energy-producing state, and would rank sixth after the United States, China, Germany, Spain and India if Texas was considered a separate nation.

The Renewable Portfolio Standard signed into law in 1999 by then governor George W. Bush set Texas on the road towards renewable energy and a leader in wind energy, producing over 8,200 megawatts of wind-generated Texas electricity. According to ERCOT or the Electric Reliability Council of Texas, wind energy accounted for 6.2 percent of the state’s 2009 Texas electricity production.

The Facts and the Hype

Texas commitment to renewable sources of energy have generated hype from all levels: claims of the state exceeding all expectations regarding wind energy generation, generation of over 15,000 more jobs, and over billion in investments – the biggest “economic boon to the state” according to President Barack Obama himself.

However, actual figures from ERCOT, the state’s grid operator, indicated that only 708 megawatts of this total wind energy capacity is reliable, particularly during the summer where Texas electricity demands are at their peak. To compensate, conventional energy generation is still utilized to sustain the more than 72,648 megawatt demands during the summer months. ERCOT projects that wind energy will eventually have significant impact on the grid by the year 2014, after transmission constraints have all been addressed.Status and Direction of Wind Energy in Texas

Recent figures have indicated a very promising outlook for the wind energy industry as 12.1 percent of the state’s total Texas electricity production by April of this year. Texas continues to have the largest wind farms and highest wind capacity nationwide, despite the problems and issues the industry faced.

Plans of building the largest wind farm in the world was discontinued due to constraints imposed by the lack of transmission lines that will bring Texas electricity from the various wind farms across the state and into the major cities that require this energy. To address this, the state is allocating over billion in investments to lay out a concrete transmission plan.

Most of Texas wind power farms are located in West Texas and the Panhandle. Now, there are not enough transmission lines that will bring the generated Texas electricity from these locations and down to the big metropolitan areas such as Dallas-Fort Worth where consumption is the highest. Once these hurdles are addressed and an efficient means of transmission are in place, the state and surrounding areas will definitely benefit from this viable source of renewable energy.

If you’ve found the webpage due to the fact that you’re interested in how to start your solar & wind energy business, you’re about to find yourself amazed. I will reveal the best techniques that will allow you to equip your house with abundant electricity for your whole family, and even generate some extra income. Am i dreaming? It won’t hurt to hear me out – take a moment to check this out.

What’s the point of spending your hard-earned money on electricity when there is equipment readily available which will bring you free solar energy, equipment that you can create and install yourself – now that’s easy! If you’re thinking it’s probably unaffordable – it’s not; that may have been the case in the past, but technology advanced and prices dropped.

How do i know all that? I had heard about some of the benefits of solar energy, and was doing some research on how to start your solar & wind energy business and it came to my attention that a considerable number of people – in our country as well as thousands of miles away – have been “enlightened” and were already using a system that enables them to convert sun-power into electricity in just few days. A little more research on the subject showed me that it can be done at an amazingly low initial cost that won’t break the bank – in fact, your bank account will thank you! At long last, we can all take advantage of a state-of-the-art technology that delivers an easy way to benefit from a free source of electricity from now on – how’s that for an incentive?

Whatever your situation – seriously interested in or just mildly curious about how to start your solar & wind energy business – do yourself a favor and verify what i say – with solar power, you can have as much electricity as you want, at no charge, and you don’t have to be dependent on the electric company or any other corporate to dole out your required electricity. I also learned that it’s commonplace to actually get paid by the electric company in your region for all extra power that you create. Here’s one more important thing to consider – by turning sunlight into electricity the final reward is that you’ll be helping to improve the planet for all of its inhabitants.

Did you know that earth receives and incredible amount of solar energy from sun which is a star that has been burning from past 4 billion years. It can supply enough energy within a minute that the planet earth would need for the entire year’s consumption. The solar radiations that hit the earth in a period of three days are equivalent the energy that can be generated from the existing fossil fuel reserves of earth. It is a myth that solar energy is not practical in populated areas.

It is just as practical in the populated areas as it is in the rural areas. An average home has enough space on roof to create electricity for the entire home’s supply. Solar energy is not only free but an inexhaustible source. The renewable solar energy was first discovered in 1767 and then in 1839, a French physicist, Edmund Becqueral discovered the “photovoltaic effect”. Even though solar energy had great potential, it was left behind whenever the mention of fossil fuels came up. But ever since the Gulf War, solar energy development took place at large scale and considering the fact that the first practical solar cell was made some 30 years ago, we have come a long way.

In the present scenario, you can find many websites offering the technology to generate your own electricity at very cheap prices. There are eBooks which can be downloaded within minutes of payment and with the help of their step by step guidance you can easily construct your own solar panels and harness the renewable solar energy.

Solar energy is sought after in many developing countries and is one of the fastest growing segments. Governments across the world are able to fill the electric needs of their villages. It is more practical than expanding the extending the wires, which are expensive, in the remote locations.

A campaign is a series of planned activities with a particular social, commercial or political aim.

Campaigning is done against nuclear weapons and war.

Similarly, advertisement, election, empowerment of women and many more activities are promoted by campaigns organized by concerned people.

Nowadays, climate change is one of the fears all living and non-living on earth face.

Crying for the climate change is a campaign active all over the world.

We are very much concerned about our future generation.

Therefore, campaigning on climate change has become popular and sometimes fashion around the world.

Realizing the importance of climate change, the Nobel Foundation awarded Nobel Peace Prize to Al Gore, the ozone man, former Vice-President of the US and the Intergovernmental Panel on Climate Change (IPCC).

They were responsible to bring out the truth that disastrous climate change is caused by global warming for which human activities contribute a lot.

No one believed the statement, but later on the scientists of IPCC calculated the human activities which influence the changes in earth’s climate.

This calculation could make the countries to wake up and think.

A documentary film “An Inconvenient Truth” produced by Al Gore opened the eyes of many politicians, planners and people from all walks of life.

In fact, the film won Oscars award for best documentary and best song.

At any cost, the man-made climate change has to be counteracted.

The bad effects of climate change on the Globe over time have been known even before two or three decades.

The green house gases – carbon dioxide, methane, nitrous oxide, halocarbons – are responsible for global warming.

The first and foremost effect is the rise in earth’s temperature.

The vulnerable people started dying during summer months in advanced countries like France and Germany.

Once everyone saw such tragic conditions around, they come forward to support the campaign on climate change.

Many organizations interested in the future of humanity cross the world began campaigning against global warming.

Rising temperature affects not only human beings but also animals and plants on Planet Earth.

Prolonged droughts and untimely rain caused crop loss and reduction in food production.

The burning of fossil fuels and large scale air-conditioning are on the increase everywhere in the world.

The commercial interest and political interference do not come forward to support the campaign against global warming.

Those people are not bothered about the far reaching results which are going to be the greatest threat to our future generation who are none other than our own children, grand-children and grand-grand children.

The campaigners caution the policy makers and politicians well in advance to take appropriate measures to reduce or arrest global warming.

In this case, the public at individual level has to cooperate and indulge in action.

The ‘Ten Things To Do” for developed nations was proposed by AL Gore as “Green Agenda”.

They are:

1. Replace incandescent bulbs with compact fluorescent lights.

2. Dive less.

3. Recycle more.

4. Check vehicle tire pressure for better mileage.

5. Use less hot water.

6. Avoid products with excessive packaging.

7. Plant a tree.

8. Turn off electrical equipment not in use.

9. Adjust your thermostat.

10. Spread the word.

The options laid out are not new to developing nations like India, because most of the organizations including the Government interested in development was campaigning these ten things for quite some time knowingly or unknowingly.

Adoption of most energy efficient technologies should be followed by everyone whether he / she lives in cities or villages.

Carbon sequestration in the soil is one of the measures by which the productivity of dry land can be increased and reduce the carbon emission according to the Director-General of ICRISAT, Hyderabad.

Incorporation of carbon and availability of organic carbon in soil help increasing the crop productivity.

Dry lands occupy 80 per cent of agricultural land and produce 58 per cent of the world’s staple foods.

Such a vast area should help in sequestration of carbon, provided we incorporate green manure regularly into the soil.

It is not a new concept again, an old one taught to me when I was a student of agriculture during 1960s.

Even today the organic farming campaigners recommend this concept to improve the soil fertility and at the same time sequestering carbon.

In this connection, one has to think of the oxidation of organic carbon in the tropical into carbon dioxide.

We are silent on this aspect.

However, I feel someone has to look into this crucial problem.

Probably, ICRISAT, a world body may think of the sequestration of carbon in tropical soils and its fate in the long run.

Forests are one of the largest ‘sink’ for carbon dioxide.

Deforestation caused by human activities and large scale wild fire brings down the ‘sink size’ and allow the earth to emit more carbon dioxide.

Coal based power plants emit enormous quantity of carbon dioxide.

Therefore, the suggestion is to opt for nuclear and solar power.

Renewable energies such as wind, solar and biofuel were highlighted as important sources to reduce the global warming to 2.0 – 2.4oC, generally recognized as the threshold level.

Report after report stresses the need for controlling the climate change through a number of campaigns all over the world – developed, developing and under develop.

Creating awareness among the people of the world is the ultimate aim of most of the organizations interested in global climate change.

Discouraging deforestation, reforestation, using ethanol based bio-fuels, expansion of conservation tillage to reduce carbon release from farm fields are some of the possible measures put forth by various committees instituted for studying the climate change.

In order to follow these policies, there should certainly be a political will and peoples’ participation.

The probability of human activities causing global warming is now 90 per cent as compared to 66 per cent in 2001 according to Dr. R.K. Pachuri, the head of IPCC.

Therefore, it is obvious that the human activities over years have contributed more and more to climate change.

If the present conditions continue, the carbon dioxide level in the atmosphere will be 550 ppm by 2100 as compared to the present level of 280 ppm.

Curbing the carbon dioxide emissions are in the hands of the US, Australia, Europe, China and India.

The threshold of carbon dioxide concentration is 450 ppm for dangerous climate change.

Global warming also causes significant sea level rise which is unavoidable for many countries during 21st Century.

The fear of global warming is felt by only some people and campaign for climate change.

It is the question of survival in the long run.

If we take it easy now then it would be difficult to cope with the problem at later stage.

Therefore, let us follow the green agenda as much as possible to support the campaign on climate change.

In 1997, the State of New York enacted a New York Solar Tax Credit for individuals to retrofit residential property and multi-family property with solar systems.

New York homeowners are eligible for a personal tax credit of up to 25% for the cost of solar system equipment and installation for solar PV systems and solar thermal systems. The maximum incentive for solar energy systems is ,000.

System sizes cannot exceed 10kW for residential solar PV systems while properties owned by condominium or cooperative housing associations are allowed up to 50kW per solar PV system.

If the tax credit exceeds your taxable liability, it may be carried-forward for the next five tax years.

To take advantage of this personal tax credit, solar PV systems must meet the New York net metering law which limits photovoltaic systems to 10kW. However the law was expanded in August 2008 with S.B. 7171 allowing for net-metering on residential photovoltaic (pv) systems up to 25kW. The state has not clarified whether or not the new net-metering law limits can be applied to this personal tax credit for solar-electric systems.

The New York State Energy Research and Development Authority (NYSERDA) also offers rebates to photovoltaic installers. This NYSERDA solar incentive is equal to .75/watt DC subject to shading, system orientation, tilt angle, and other derates to performance. No eligible system size has been specified and production output may not exceed 110% of the required annual energy load. The maximum NYSERDA solar incentive amounts and system capacities are as follows:

Residential: ,750, 5kW

Non-residential: 2,500, 50kW

Non-profit, government, schools: ,250, 25kW

There are also local options to help property owners install solar. Solar systems have a 100% property tax exemption up to 15 years. Another local option is a Municipal Sustainable Energy Program where property owners use Property-Assessed Clean Energy (PACE) financing to pay for renewable energy upgrades. In July 2005, New York made all sales and installations of residential solar-energy systems 100% exempt from the state sales tax and use tax.

The State of New York will benefit from distributed energy sources. By distributing energy sources, it promotes energy security and eventually energy independence (with the installation of renewable energy). With the New York Solar Tax Credit for individuals and other incentive programs, New York is well on their way to meeting their renewable energy goals.
