The U.S. Department of Energy is a proud supporter of American Solar Challenge, a biennial solar-powered car race for colleges and universities in North America. Students design, build and race their custom-designed vehicles on a designated cross country route. The competition inspires students to work in teams, promotes out-of-the-box thinking, and encourages forward thinking.
Solar technology isn't new. It probably started some time in the 7th Century B.C., when people learned how to use glass and sunlight to light a fire. But today's sophisticated solar technologies include everything from solar-powered lights and buildings to solar-powered vehicles.
Here, you can learn more about some major milestones in the historical development of solar energy technologies. You will also get a glimpse of "the solar future."
