Solar Frontiers (Video 8 of 8) - Unravel Travel TV

As global leaders assemble in Paris in 2015 to discuss the future of climate change at COP21, The Economist has released 8 film clops about the people and projects pushing the frontiers of solar power around the world. 'Solar Frontiers' is the third episode in the “Global Compass” series of mini-documentaries, examining new approaches to thorny social and policy problems. The film starts (video 1 of 8) in Haiti. Ravaged by an earthquake in 2010, it has since become a proving ground for new approaches to “off grid” electricity, including solar lighting. Globally, around 25% of people lack access to the electrical grid; in Haiti, it’s 75%. But the off-grid solar power has its enthusiasts in the developed world, too. The film visits a steel works in Alabama that generates 100% of its own power, using vast solar arrays. Meanwhile, researchers are looking for new ways to make solar panels more efficient. One of the most promising approaches involves a new class of materials called perovskites.
