The following interesting graphic comes from 1BOG (One Block Off the Grid), a company that helps consumers pool together to get discounts on solar panel installation. The graph extrapolates the growth of solar power if its use were increasing at the rate of Facebook’s growth. Currently, solar power grows 60% each year, according to 1BOG. If it were to somehow expand at Facebook growth rates, however, all of California would be powered by solar in a little over a year. After 3.5 years, the entire U.S. would be powered by the sun, and in 4.7 years the entire world would run on solar power. Of course, while unrealistic that this would happen, it is a neat brain bender to think about. (Graph after the jump).
