The initiative and early development of wind power in California came during Governor Jerry Brown's first two terms in the late 1970s and early 1980s.{{Cite web|url=https://www.awea.org/turbine-timeline-1980s|title=U.S. wind energy grows in California, then stagnates nationwide in the 1980s|website=American Wind Energy Association|access-date=2018-04-09}}{{Cite web|url=http://www.sacbee.com/opinion/op-ed/soapbox/article138660243.html|title=Don't let wind energy stall|last=Hochschild|first=David|date=March 21, 2017|website=Sacramento Bee|access-date=2018-04-08}} The state's wind power capacity has grown by nearly 350% since 2001, when it was less than 1,700 MW.{{cite web|url=http://apps2.eere.energy.gov/wind/windexchange/wind_installed_capacity.asp|title=WINDExchange: Installed Wind Capacity|last=|first=|date=2016-02-17|website=energy.gov|publisher=U.S. Department of Energy|access-date=2017-01-24}}{{cite web| url= http://www.awea.org/learnabout/publications/reports/upload/AWEA-Fourth-Quarter-Wind-Energy-Industry-Market-Report_Executive-Summary.pdf| title= AWEA 4th quarter 2012 Public Market Report| date= January 2013| publisher= American Wind Energy Association (AWEA)| access-date= January 30, 2013| archive-date= May 18, 2013| archive-url= https://web.archive.org/web/20130518072413/http://www.awea.org/learnabout/publications/reports/upload/AWEA-Fourth-Quarter-Wind-Energy-Industry-Market-Report_Executive-Summary.pdf| url-status= dead}} According to the California Wind Energy Association (CalWEA), as of 2020, California had approximately 5,787 MW of wind energy capacity installed across the state.{{Cite web |date=2012-02-03 |title=CalWEA |url=http://www.calwea.org/bigPicture.html |access-date=2025-05-03 |archive-url=https://web.archive.org/web/20120203055822/http://www.calwea.org/bigPicture.html |archive-date=February 3, 2012 }} In 2020, wind projects in California generated 13,703 gigawatt-hours (GWh) of electricity, accounting for 7.2% of all power generated within the state.{{Cite journal |last1=Silverman |first1=Rochelle E. |last2=Flores |first2=Robert J. |last3=Brouwer |first3=Jack |date=December 2020 |title=Energy and economic assessment of distributed renewable gas and electricity generation in a small disadvantaged urban community |url=https://doi.org/10.1016/j.apenergy.2020.115974 |journal=Applied Energy |volume=280 |pages=115974 |doi=10.1016/j.apenergy.2020.115974 |bibcode=2020ApEn..28015974S |issn=0306-2619|url-access=subscription }}Additionally, California imported 16,635 GWh of wind energy from out-of-state projects, representing 20% of total power imports. Combined, wind energy supplied 11% of California's total system power in 2020, enough to power the homes in Sacramento, San Francisco, and Los Angeles Counties combined. Most of California's wind generation is found in the Tehachapi area of Kern County, with some large projects in Solano, Contra Costa and Riverside counties as well. California is among the states with the largest amount of installed wind power capacity. In recent years, California has lagged behind other states when it comes to the installation of wind power. It was ranked 4th overall for wind power electrical generation at the end of 2016, behind Texas, Iowa, and Oklahoma. As of 2019{{Needs update|date=May 2025}}, California had 5,973 MW of wind power generating capacity installed.

History

{{further|Wind power in the United States}}

California was the first U.S. state where large wind farms were developed, beginning in the early 1980s.{{Cite web|url=http://awea.files.cms-plus.com/FileDownloads/pdfs/California.pdf|title=Wind Energy in California|website=American Wind Energy Association|access-date=1 May 2018}} By 1995, California produced 30 percent of the entire world's wind-generated electricity.{{cite web|title=Overview of Wind Energy in California|url=http://www.energy.ca.gov/wind/overview.html|publisher=California Energy Commission|archive-url=https://web.archive.org/web/20170118102209/http://www.energy.ca.gov/wind/overview.html|archive-date=2017-01-18}} Wind power in Texas surpassed the production in California to become the leader in the United States.

Historically, most of California's wind power output has been in three primary regions: Altamont Pass wind farm (east of San Francisco); Tehachapi Pass wind farm (south east of Bakersfield) and San Gorgonio Pass wind farm (near Palm Springs, east of Los Angeles). A fourth area, the Montezuma Hills of Solano County, was developed in 2005–2009, with the large Shiloh wind power plant.

The Alta Wind Energy Center is a wind farm located in Tehachapi Pass in Kern County.{{cite web|title=World's Largest Wind Project is Underway|url=https://www.renewableenergyworld.com/articles/2010/07/worlds-largest-wind-project-is-underway.html|website=RenewableEnergyWorld.com|access-date=2018-04-14|date=July 29, 2010}} Kern County is reviewing a number of other proposed wind projects that would generate a combined 4,600 megawatts of renewable energy if approved.{{cite web|title=California's largest wind power projects has been approved by Kern County|url=https://www.evwind.es/2009/12/17/californias-largest-wind-power-projects-has-been-approved-by-kern-county/2880|website=REVE|access-date=2018-04-14|date=December 17, 2009}}{{Update inline|date=August 2021}}

Offshore wind

A 2009 Stanford University study of California offshore wind potential identified a site off Cape Mendocino that could provide uninterrupted year-round power from a 1500 MW wind farm that would produce an average of 790 MW. Three types of offshore wind power were studied, with the conclusion that from 12,300 to 19,700 GWh/yr could be delivered from 1,997 to 3,331 MW of monopile wind turbines installed in up to {{convert|20| meter||adj=mid| deep water|order=flip}}, from 38,200 to 73,000 GWh/yr could be delivered from 6,202 to 12,374 MW of multi-leg wind turbines in {{convert|20 |to| 50| meter||adj=mid| deep water|order=flip}}, and from 462,100 to 568,200 GWh/yr from 73,025 to 91,707 MW of floating turbine foundation wind turbines in from {{convert|50 |to| 290| meter||adj=mid| deep water|order=flip}},[http://www.stanford.edu/~dvorak/papers/dvorak-archer-jacobson-2010-california-offshore-wind-energy-potential.pdf California offshore wind energy potential] such as those being studied for use off the coast of Maine by the Ocean Energy Institute and the DeepCwind Consortium.

In April 2018, several power development companies joined with Redwood Coast Energy Authority to explore the idea of creating a large-scale wind farm off of the Northern California coast. Deep water has hindered development off the coast of California, making the use floating turbines more feasible than fixed turbines. The group decided to propose instead. RCEA and the development companies intended to file a lease with the Bureau of Ocean Energy Management in the summer of 2018 for the 120-150 MW project.{{Cite news|url=https://www.reuters.com/article/usa-wind-offshore/group-pursuing-floating-wind-farm-off-california-coast-idUSL2N1RG237 |title=Group pursuing floating wind farm off California coast|author=Reuters Editorial|work=U.S.|access-date=2018-04-04|language=en-US}} The Humboldt Project will be located just over {{convert|20 |miles}} west of Eureka, California and estimates have the date of completion to be sometime in 2024.{{cite web|title=California Chooses Floating Offshore Wind Technology|url=https://www.maritime-executive.com/article/california-chooses-floating-offshore-wind-technology#gs.0HD8zIg |website=The Marine Executive|access-date=6 April 2018}} In 2022, the US Bureau of Ocean Energy Management (BOEM) issued a statement of no significant environmental impact,{{cite web |title=BOEM completes California offshore environmental study |url=https://renews.biz/77657/boem-completes-california-offshore-environmental-study/ |website=reNEWS - Renewable Energy News |date=6 May 2022}} and California set a target of 25 GW of offshore wind by 2045.{{cite web |last1=Buljan |first1=Adrijana |title=California Adopts 2045 Offshore Wind Target, Plans Installing 25 GW by That Time |url=https://www.offshorewind.biz/2022/08/11/california-adopts-2045-offshore-wind-target-plans-installing-25-gw-by-that-time/ |website=Offshore Wind |date=11 August 2022}}
