SOLAR ENERGY

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

     According to the United States Environmental Protection Energy (EPA) enough sunlight reaches the earth's surface every year to produce approximately 1,00 times to amount of energy produced by burning all fossil fuels mined and extracted during the same time period.

     As with renewable energy system, the initial costs of setting up these solar energy projects is quite expensive. However, the saving on electricity bills in the long-term should make up for this and year after year, the costs of these solar energy are falling 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 government announced a £ 10 million investment into photovoltaic (PV) technologies over the next three years.

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

     Street lighting and traffic signal can also benefit for this power supply further reducing our dependence on fossil fuels and nuclear energy.
