Solar power alternative energy.

From solar to wind find out more about alternative energy the fastest growing source of energy in the world and how we can use it to combat climate change. Solar power is the conversion of energy from sunlight into electricity either directly using photovoltaics pv indirectly using concentrated solar power or a combination concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. At a smaller scale we can harness the sun s rays to power the whole house whether through pv cell panels or passive solar home design. Though costly to implement solar energy offers a clean renewable source of power.

Over the past few years the cost of a solar energy system has dropped significantly helping to give more american families and business access to affordable clean energy. Sre s breadth in solar investing development and construction delivers cost effective. The tremendous growth in the u s. Solar renewable energy llc sre has developed over 80 solar arrays and with an asset value of 170 million and is a driving force behind new solar generation in the mid atlantic.

These include biomass energy wind energy solar energy geothermal energy hydroelectric energy sources. Solar power is produced by collecting sunlight and converting it into electricity. Combined with the use of recycling the use of clean alternative energies such as the home use of solar power systems will help ensure man s survival into the 21st century and beyond. Learn how solar power works the benefits it offers and some of the pitfalls.

Through a portfolio of r d efforts the energy department remains committed to leveraging america. Solar power is an alternative source of energy which is capable of producing heat and generating electricity. The co inventor of paypal now turned alternative energy rock star has built two companies solar power utility solarcity and electric car company tesla around the idea that solar generated. Solar industry is helping to pave the way to a cleaner more sustainable energy future.

Photovoltaic cells convert light into an electric current using the photovoltaic effect. The amount of solar energy the earth receives on a sunny day is capable of generating around 200 000 times the total daily amount of energy required to power our. This is done by using solar panels which are large flat panels made up of many individual solar cells. It is most often used in remote locations although it is becoming more popular in urban areas as well.
