There are almost 60 000 utility-scale wind turbines installed in the U.S, with a cumulative wind energy capacity of 107.4 GW. These statistics suggest that there was an increased wind capacity of 166% in the U.S from 2010 until 2020. As renewable energy becomes increasingly popular, here is an overview of global wind energy.
Global wind farm facts
- From 2009 to 2019, the global wind capacity increased on average by 15% annually.
- The overall capacity of globally installed wind turbines reached 650,8 GW by the end of 2019.
- 2019 was the second-strongest wind year in terms of market size, yielding a growth rate of 10,1%.
- All wind turbines that were installed by the end of 2019 can meet more than 6% of the global electricity demand.
- When it comes to total installed wind capacity in the U.S., the leading states are Texas (29,407 MW), Iowa (10,644), and Oklahoma (8,173 MW).
- The average turbine size increased in the U.S. by 5% from 2017 to 2018.
- During the same period, new wind energy purchase contracts averaged 1.3-1.8c per kWh. in 2019, the average residential electricity price was 13.0c per kWh.
Wind energy performance and impacts on the environment
- U.S. wind capacity avoided millions of metric tons of carbon dioxide emissions and used approximately 103 billion gallons less water than conventional power plants in 2019.
- Studies have found that if wind-generated electricity in the U.S. reaches a capacity of 35% by 2050, the greenhouse gas emissions from the electric sector would be reduced by 23%.
- Although noise factors are often cited as a challenge for wind farms, the typical noise from a wind project is between 35-45 dB from a distance of 350m. Studies have shown that a quiet bedroom measures 35 dB.
