Four U.S. states generated 30 to 37 percent of their energy from wind power in 2017. That’s just one of the findings of the Department of Energy (DOE)’s annual Wind Technologies Market Report, released August 22.
Oklahoma, Iowa, Kansas and South Dakota were the leaders in terms of how much wind contributed to their state’s overall electricity generation, but 14 states got more than 10 percent of their in-state energy from wind power last year. Texas took the lead in added wind capacity, installing 2,305 megawatts worth.
Overall, 2017 was a good year for U.S. wind power, with $11 billion invested and 7,017 megawatts of capacity added to increase total U.S. wind capacity to 88,973 megawatts.
The U.S. added the second most wind capacity globally in 2017 after China, but when it comes to the percentage of energy the U.S. generates from wind, the U.S. lags farther behind. While wind power meets around 48 percent of Denmark’s electricity demand, and around 30 percent of Ireland and Portugal’s, it accounts for only 7 percent of overall U.S. electricity demand in an average year.
Low costs are currently helping the U.S. wind industry to grow.
