The actuality: solar Energy is the energy of sunlight collected and used to provide electricity, to heat water, and to heat or cool homes, businesses or industry. Sunlight is a clean, renewable source of energy. It is a sustainable resource, meaning it doesn't run out, but can be maintained because the sun shines almost every day. Coal or gas are not sustainable or renewable: once they are gone, there is none left. More and more people are wanting to use clean, renewable energy such as solar, wind, geothermal steam and others. It is called 'Green Power'.
The aim: environmental Impact Although Solar energy is considered to be one of the cleanest and renewable sources of energy among the available sources but is has some environmental impacts too. Solar energy uses photovoltaic cells to produce solar power. However, manufacturing the photovoltaic cells to produces that energy requires silicon and produces some waste products. Inappropriate handling of these materials may lead to hazardous exposure to humans and the environment. Installing solar power plants may require large piece of land, which may impact existing ecosystems. Solar energy does not pollute the air when converted to electricity by solar panels. It is found in abundance and does not help in global warming. Future Of Solar Energy Solar technology is now poised to play a larger role in the future, thanks to new developments that could result in lower costs and improved efficiency. In fact, the solar PV industry aims to provide half of all new U.S.
electricity generation by 2025. More and more architects are recognizing the value of active and passive solar and learning how to effectively incorporate it into building designs. Solar hot water systems can compete economically with conventional systems in some areas. Perhaps the future is here now. Shell has predicted that 50% of the world’s energy will come from renewable sources by 2040. In recent years manufacturing costs of photovoltaic cells has dropped by 3-5% per year while government subsidies have increased. While to some such facts about solar energy seem trivial, this makes solar energy an ever-more affordable energy source. In the next few years it is expected that millions of households in the world will be using solar energy as the trends in USA and Japan show. Aggressive financial incentives in Germany and Japan have made these countries global leaders in solar deployment for years.
The aim: thanks to the technology of photovoltaic cells, it is now possible to convert energy from the sun directly into electricity that can be used in the home. With solar electric systems, you can enjoy free inexhaustible, renewable power that is environment friendly as well. If you’re looking to move down the do it yourself path, this is by far the easiest, simplest and most inexpensive way I have found to get started with utilizing the infinite supply of energy from the sun. The supply is unlimited so it really just depends on how much of it we want to use. Run a small appliance or two or produce enough to replace your entire electric bill. It is all up to you.
