In Saved by the Sun, NOVA poses the burning question: Can solar power help save the Earth from the ravages of global warming? In the face of steeply rising oil prices and political turmoil in the Middle East, there's new urgency and enthusiasm for finding ways to make solar power more efficient and affordable. From individuals installing solar panels on their roofs to industrial-scale projects in the Mojave desert featuring massive arrays of mirrors, solar power is gaining ground in the US. And in Germany, the world's leading developer of solar power is on track to produce 30 percent of its electricity from renewable sources by 2020. Breakthroughs in nanotechnology could make solar's future even brighter. NOVA presents a provocative mix of scientist, economists, and ordinary citizens who are all pushing the envelope of solar power's untapped potential. Special DVD features include: materials and activities for educators; a link to the NOVA Web site; scene selections; closed captions; and described video for the visually impaired. On one DVD5 disc.
