National Economics Editorial Staff: Renewable energy advocates have claimed for decades that solar and wind power are the future. Some boldly state that the world could be powered by renewable energy sources as early as 2030, given the exponential growth of solar and wind electrical capacity. And of course, the mainstream media plays up the importance of solar and wind energy in defeating the scarecrow that is climate change. While 13.6% of world energy comes from renewable sources, the vast majority—72.8%—is just people in developing countries burning wood, charcoal, and dung for energy. That’s right: feces is a more important energy source than wind power.
