In 1883, Charles Fritz turned the sun's rays into electricity!

Interest slowed down in the early part of the 20th century, though interest in a solar-powered civilization never completely disappeared.

It was around this time, in fact, that a certain Albert Einstein was awarded the 1921 Nobel Prize in physics for his research on the photoelectric effect.

In 1953, Bell Laboratories scientists Gerald Pearson, Daryl Chapin and Calvin Fuller developed the first silicon solar cell capable of generating a measurable electric current.

The 1970s brought hope that through massive investment in initiatives and research, solar pv costs would drop dramatically, allowing it to become competitive with fossil fuels.

However, it hasn't been until recently and due to major governmental intiatives of Germany and Japan that the solar industry has strated to take off.

The solar photovoltaic energy market is currently growing at a whopping 30 percent per year.

Meanwhile, solar thermal water heating is an increasingly cost-effective means of lowering gas and electricity demand.
