Solar technology isn’t new. Its history spans from the 7th Century B.C. to today. We started out concentrating the sun’s heat with glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solarpowered vehicles.Here you can learn more about the milestones in the historical development of solar technology,century by century, and year by year. You can also glimpse the future.Technology roadmaps for the future outline the research and development path to full competitiveness of concentrating solar power (CSP) with conventional power generation technologies within a decade. The potential of solar power in the Southwest United States is comparable in scale to the hydropower resource of the Northwest. A desert area 10 miles by 15 miles could provide 20,000 megawatts of power, while the electricity needs of the entire United States could theoretically be met by a photovoltaic array within an area 100 miles on a side. Concentrating solar power, or solar thermal electricity, could harness the sun’s heat energy to provide large-scale, domestically secure, and environmentally friendly electricity.
