Wind Energy Is Now The Largest Source Of Clean Energy In The U.S.
Wind power has now overtaken hydroelectric as the largest single source of clean energy in the United States. With 82 thousand MWs of total installed capacity at the end of 2016, wind turbines exceeded the 80 thousand MWs generated by the nation’s hydroelectric dams. This comes on the heels of the EIA’s short-term energy outlook which predicts wind and solar power will continue to account for the fastest growth in the U.S. energy sector, repeating a trend from last year. The EIA predicts wind power will reach 94 thousand MWs by 2018.
Wind hasn’t surpassed hydroelectric power in all categories, however; in terms of actual power generated, dams still out-perform wind turbines, as they tend to stay on for more of the year. But with few dams planned for construction, it’s likely wind power will exceed hydroelectric in actual power produced in the next few years.
The American Wind Energy Association (AWEA) has reported that 10 thousand MWs in new power is currently under construction, including the Amazon Wind Farm off the coast of Elizabeth City, NC, the nation’s first large off-shore wind farm. Last year, 8200 MWs was added, most of it in the year’s final quarter.
Much of the growth is being driven by Texas, by far the country’s largest producer of wind power and the industry’s leader in adding new capacity. Texas produces 20 thousand MWs, around a quarter of the national total, and maintains more than 11 thousand turbines, which produce 13 percent of the state’s total power. Texan interest in wind power, which grew under Governor Rick Perry, has wind energy advocates hopeful that Perry’s current role as Secretary of Energy won’t prove an impediment to additional growth.
Further interest in wind power may be generated by the sector’s growing role as a job creator. Wind power provides employment for about 100,000 people nationwide, far more than the coal industry. Bloomberg has reported that wind power advocates and developers have been urging the federal government, which has shown considerable interest in rejuvenating the U.S. coal industry, to instead shift their attention to wind power.
Much of the sector’s growing capacity is coming in rural areas, chiefly in the Midwest. North Dakota, to name one example, has seen 3 thousand MWs installed in the past decade, and one-third of that total in just the last 10 months.
Internationally, the U.S. remains way behind China in terms of wind power capacity. Of the 54 GW installed worldwide in 2016, China accounted for 42 percent, or 23.3 GW. According to Chinese projections, by 2030 wind turbines will supply 26 percent of total electricity demand. China cannot produce electricity with the same efficiency as American turbines, according to Bloomberg, chiefly due to inadequate transmission lines.
