Imagine If Solar Power Grew Like Facebook [Infographic]

While solar power grows at a rate of 60% each year, that’s nothing compared to the roughly 275% growth that Facebook experienced year-over-year, growing from about 175 million users last year to over 500 million this summer. So what if solar power grew at the rate that Facebook acquired new users? The folks at One Block off the Grid (1BOG) wanted to know, and they created this nifty infographic to help visualize it. The most startling finding? The world could be totally powered by solar energy in under five years.
