Nine gigawatts of wind turbines were added last year in the US

Earlier this year in the US, energy generation from wind, solar, and hydroelectric dams combined to top coal generation for over two months straight. This was the product of spring peaks in renewable generation and reduced electrical demand during lockdowns, but those events were layered on top of coal's continuing decline and the long-term growth of renewables. A new report from the Lawrence Berkeley National Laboratory looks back at 2019-what is now known as the Before Times-to tally up year-end totals for the wind industry.

The topline number is that a little over nine gigawatts of wind capacity was added last year-slightly more than in each of the four previous years. Wind accounts for about one-third of all new generation added in 2019, and it ticked up to seven percent of all electricity generated in the US.

But as for the grid carrying that electricity, a little under 1,000 miles of transmission lines were built last year-the second lowest amount in the last 10 years.
