How has wind power changed over the last year?

U.S. wind capacity increased steadily over the last several years, more than tripling from 47.0 GW in 2010 to 147.5 GW at the end of 2023. Electricity generation from wind turbines also grew steadily, at a similar rate to capacity, until 2023.

This decline rate appears stable until 2002, after which it reduces for more recently commissioned turbines. Farms built before 2003 have an average decline rate of −0.49 ± 0.05 points per year, whereas those built afterwards average −0.16 ± 0.08.

Why did wind generation decline in 2023?

The 2023 decline in wind generation indicates that wind as a generation source is maturing after decades of rapid growth.

How much electricity does a wind turbine generate in 2023?

U.S. electricity generation from wind turbines decreased for the first time since the mid-1990s in 2023 despite the addition of 6.2 gigawatts (GW) of new wind capacity last year. Data from our Power Plant Operations Report show that U.S. wind generation in 2023 totaled 425,235 gigawatthours (GWh), 2.1% less than the 434,297 GWh generated in 2022.

Why do wind farms lose output a decade?

Onshore wind farm output falls 16% a decade, possibly due to availability and wear. Performance decline with age is seen in all farms and all generations of turbines. Decreasing output over a farm's life increases the levelised cost of electricity. Ageing is a fact of life.
