Capacity factor can also be used to estimate the expected electricity production of a wind farm, by multiplying nameplate capacity times 8,760 (the number of hours in a year) times capacity factor. This information is crucial for assessing the viability and profitability of wind energy. . Total annual U. electricity generation from wind energy increased from about 6 billion kilowatthours (kWh) in 2000 to about 434 billion kWh in 2022. In 2022, wind turbines were the source of about 10. utility-scale electricity generation. Ember (2026); Energy Institute - Statistical Review of World Energy (2025) – with major processing by Our World in Data This is the. . Approximately 2% of the solar energy striking the Earth's surface is converted into kinetic energy in wind.

What is end-year rush to complete wind power facilities?
We report the outage hours to give a more intuitive indicator. The measure of end-year rush to complete wind power facilities, rush, is defined as the capacity installed during December as a share of that year's total. We expect that the end-year installation rush affects electric reliability during the following year.
How does the Year-End installation Rush affect wind and solar power?
The notable prevalence of both wind and solar power in the northwestern grid renders it susceptible to the disruptive effects of the year-end installation rush in wind power. Given its high share of wind power, any concentrated surge in installations towards the end of the year intensifies the strain on the existing infrastructure.
How does end-year installation Rush affect wind power reliability?
Incentive structure led to rushes to install wind power before year end expiration. Use provincial electric reliability data to show effects of end-year installation rush. Find strong negative effects especially in Northwestern grid with high wind share. Reliability in urban areas is more affected than rural areas by installation rush.
Do end-year rushes aggravate the shock of wind power penetration?
The structure of wind-power incentives in China has led to the phenomenon of end-year rushes to install wind power (more details in Section 2 ). In this study, we examine how these end-year rushes of wind power installation may aggravate the shock of wind power penetration on electric reliability.
