South Africa gets a lot of Sun. So much so that the country is investing in solar powered airports and already has one that's fully operational. George airport in southern South Africa last year became powered entirely by solar energy. According to AFP, this move lowered its carbon dioxide emissions by more than a thousand tons. The hub runs on energy garnered by some two thousand solar panels. These power everything from the atms, restaurants to the check-in desk ans airport control tower. Excess energy is transferred to nearby homes on a local power grid. South Africa is already working on to other solar powered airports elsewhere in the country. The airport is Africa's first to run on solar energy alone and one of only two in the world.
