This Chart Shows How Quickly Wind Power Has Caught On
Yes, wind power is “green,” but it didn’t become a force on the energy landscape until it also became cheap. Over the past decade, that has begun to happen, thanks to a combination of improvements in technology and federal and state tax incentives. As Stephen Gandel and Katie Fehrenbacher report this week in Fortune, the average cost of wind energy dropped by about a third between 2008 and 2013; in some parts of the country, it’s the cheapest electricity source available. Not coincidentally, as the chart below shows, wind’s share of renewable-energy output has soared. The Department of Energy expects wind to generate 10% of America’s electricity by 2020, up from about 7% today. (By comparison, coal and natural gas today each account for about a third.)
