As we are involved in one energy crisis after another, we finally need to look at solar power and how it can be used to help us not only conserve energy and save money, but be more environmentally friendly. With the talk of global warming and the need for alternative energy sources you might hear that term is solar power mentioned on the news cast or in the newspapers. What exactly is solar power? Solar power is energy directly from the sun. The sun's energy is responsible for supporting life on Earth and it also creates the winds and weather conditions on our planet. Solar power can be attributed to creating wind. When that wind is harnessed by wind turbines, it creates analytical energy. Ancient cultures, a long time ago, collected solar power by having windows or doors that faced the sun.

The sun would come in through these openings and warm the interior of the home. Homes were also built to protect against the wind. The least used part of the house was always facing north.

Solar power and solar energy is basically the same thing. It's the conversion of sunlight into electricity which is then used in our homes. Solar power can be used directly by using the photovoltaic effect or by heating some kind of fluid in a generator. When the sun heats the liquid, the steam rises, turning the turbines of the generator. This produces electricity which is used in homes, automobiles, and industry needs.
