Pure Energy

     Many believe that solar energy is a very recent technological breakthrough. In fact, its beginnings originated hundreds of years ago. Solar thermal power has been used for centuries to dry clothes and to preserve different types of food. Even children know that when you focus sunlight into a lens or a mirror can produce enough energy to light a fire.

     A definition of solar energy in the shortest form should read: electricity produced using solar light.

     Another definition, more accurate, it would be this: the energy received from the sun, in the form of sunlight, attracted by the solar panels or solar collectors and converted into electricity or heat.

      More than a hundred years ago, the inventors have discovered how they can capture sunlight for energy. They built impressive arrangements to fulfill this task and learned most of what we know today about solar energy.

     The oldest use of solar energy dates from 1860 and is attributed to Auguste Mouchout, professor of mathematics, French. He began work in this area due to concern that coal reserves which depended France is over. So he invented an engine that converts solar energy into electricity. Afterward, he and others have created devices more efficient solar energy. Shortly, this way of producing electricity turned into a work in progress continuously.

     In 1970, with the U.S. experienced energy crisis, solar energy came to light again. Many people were convinced that the nation would have to install photovoltaic panels on the roof of each building. To obtain thermal energy using a special rig that draws solar energy by using a solar collector. This type of energy was ideal for household water heating. Then, the crisis was over. Solar panels have become more expensive, and people back again behind solar energy and electricity.

     Nowadays, when we haunt a new energy crisis, solar power seems to be, again, all the better alternative.
