Deserts aren't just a result of climate change, they can also help stop it. Just ask the University of Tokyo researchers behind the Sahara Solar Breeder Project, an initiative that aims to produce 50 percent of the planet's electricity by 2050 -- by converting sand into solar panels.
Ever wonder how much space we would need to use to power the entire world with solar energy or offshore wind power? So did the good people at the Land Art Generator, who created two infographics that show the amount of surface area required to power our planet with renewable resources.
The world's largest and most ambitious solar power initiative, dubbed "Desertec", is pushing ahead on July 13 with a meeting of a 20-firm consortium, including companies like Siemens, Deutsche Bank, and E.on. Companies present at the meeting will determine the next step for the German-led project, which will ideally take solar power from North Africa and transmit it to Europe.
