US onshore wind turbines were bigger, taller, and more productive than ever in 2020, while advancements in technology are pushing down the cost of new equipment and installed projects, according to a new Department of Energy (DoE) report.

Last year, the average rated nameplate capacity of newly installed turbines was 2.75MW, up 8% from 2019, while average rotor diameter was 124.8 meters, a 3% increase.

The trend toward larger turbines is being driven by advancements in technology, improved siting techniques and more public acceptance as the country transitions to clean energy sources, said the authors of Land Based Wind Market Report: 2021, prepared by DoE’s Office of Energy Efficiency and Renewable Energy.
