The solar energy history

In the early 20th century, Albert Einstein and a number of other scientists studied the behavior of light. A process called "the photoelectric effect" became an important factor, which inventors used to improve upon solar-collector technology, and to create more efficient ways of using solar energy.

With the study of the photoelectric effect and the increasing use of silicon, came the rise of photovoltaic technology in the 1950's.

The first true photovoltaic solar cells exploded onto the scene as industries all over the world jumped at the technology and developed them for efficient use. Solar panels began to be utilized to run satellites and other large systems, and modern solar technology gradually replaced earlier devices, such as glass hotboxes. Solar energy also became known as an alternative to fossil fuels, and was incorporated into power plants.

Solar Power and the Future

The need to use clean forms of energy is becoming rapidly more apparent, as mankind becomes increasingly aware of the consequences global irresponsibility. Fuels are becoming more costly, and we begin to realize that our sources of fossil fuels are finite and not endless. We have a duty to protect ourselves and our home planet. We must start to look ahead and realize that the answer comes from above. The sun is free, and it is well within our rights to use it.
