Solar Energy

Solar Energy

        Solar energy is one great altemative for future energy sources.it is environmentally friendly and is renewable,thus is an excellent energy source.

         According to the United States Environmental Protecion Agency (EPA): Enough sunlight reaches the earth’s surface every year to produce approximentely 1.000 times the amount of energy produced by burning all fossil fuels mined and extracted during the same time periode.

          As with most renewable energy system, the initial costs of setting up these solar energy project is quite expensive. However, the savings on electricity bills in the long-term should make up this and year after year, the cost of these solar energy are felling which will make it more affordable and widespread.

          Solar energy will also be powering some 70,000 homes and several hundred businesses in Britain soon after the goverment announced a 10 millons investment into photo (PV) technologies over the next three years.

               Photovoltaic cells provide an unlimited supply of tree power by converting sinlight into electricity using modem semiconductors. Vast arrays of these cells will be placed on roofs and walls around the country to provide buildings with a renewable source of energy for lighting, heating, and storage.

               If the cost of catching solar light in cheap, it will make us hope that fuel energy can be replaced by solar energy. It will answer scientist worry about the shortage of energy.
