Wind power is one of the main renewable energy sources in Australia. In 2019, wind power accounted for 8.5% of Australia's total electricity demand and 35.4% of total renewable energy supply. As of December 2019, there was 6,279 megawatt (MW) of installed wind power capacity and a further 21,845 MW of capacity was proposed or committed to the electricity sector in Australia as of February 2020. At the end of 2019 there were 101 wind farms in Australia, most of which had turbines from 1.5 to 3 MW. In addition, 30 projects with a combined installed capacity of more than 5,500 MW are either under construction or committed to be built in 2020/21 having reached financial closure. Australian wind power to grid peaked at 4 GW in February 2019.
By year end 2015 Spain was the world's fifth biggest producer of wind power with 23,031 MW installed capacity, providing 48,118 GWh of power and 19% of the country's total electricity production in that year. In 2014, a record breaking year for renewable electricity production, wind power accounted for 20.2% of total electricity generation in Spain making it the second most important electricity source after nuclear power (22%) and ahead of coal power (16.5%). In earlier periods wind energy covered 16% of the demand in 2010, 13.8% in 2009 and 11.5% in 2008.
Wind power became a significant energy source within South Australia over the first two decades of the 21st century. As of 2015, there was an installed capacity of 1,475 MW, which accounts for 34% of electricity production in the state. This represents 35% of Australia's installed wind power capacity.
Wind power in the United States is a branch of the energy industry that has expanded quickly over the latest several years. From January through December 2019, 300.1 terawatt-hours were generated by wind power, or 7.29% of all generated electrical energy in the United States. That same year, wind power surpassed hydroelectric power as the largest renewable energy source generated in the U.S.
Wind power in Ohio has a long history, and as of 2016, Ohio had 545 megawatts (MW) of utility-scale wind power installations installed, responsible for 1.1% of in-state electricity generated. Over 1000 MW more were under construction or pending approval. Some installations have become tourist attractions. There has been a sudden increase in generating capacity, as total wind power capacity in the state was just 9.7 MW in 2010. By 2019, there were 738 MW of capacity, which generated 1.71% of Ohio's electricity.
As of 2020 the Republic of Ireland has 3700 megawatt of installed wind power nameplate capacity.
Making up 42% of the state's generated electricity in 2019, wind power is the largest source of electricity generation in Iowa. In 2019, over 26 billion kWh of electrical energy was generated by wind power. As of Q3 2020, Iowa has over 10,951 megawatts (MW) of installed capacity with 5,590 wind turbines, ranking 2nd and 3rd in the nation below Texas respectively.
New York ranked 11th in the United States at the end of 2013 for installed wind power capacity, with 1,722 MW installed. In 2016, wind power provided 2.94% of in state energy production. This increased to 3.66% in 2019.
Wind power in Indiana was limited to a few small water-pumping windmills on farms until 2008 with construction of Indiana's first utility-scale wind power facility, Goodland with a nameplate capacity of 130 MW. As of September 2017, Indiana had a total of 1897 MW of wind power capacity installed, ranking it 12th among U.S. states. Wind power was responsible for 4.8% of in-state electricity production in 2016.
There are more than twenty wind power projects operating in the commonwealth of Pennsylvania. The most productive wind energy regions generally fall in mountain or coastal terrains. The northern portion of the Appalachian chain, including most of Southwestern Pennsylvania, is one of the areas with the highest potential for wind energy in the Eastern United States. The mountain ridges of central and northeastern Pennsylvania, including the Poconos in the eastern part of the state, offer some of the best wind resources in the region.
Meadow Lake Wind Farm is an 801.25 megawatt (MW) wind farm near Brookston and Chalmers, Indiana, spreading over portions of White, Jasper, and Benton Counties. It is owned and operated by EDP Renewables North America. The facility currently has six operational phases, with 414 turbines, and is a prominent feature on both sides of Interstate 65 in western Indiana.
As of 2016, Arizona has 268 megawatts (MW) of wind powered electricity generating capacity, producing 0.5% of in-state generated electricity.
The U.S. state of Massachusetts has vast wind energy resources offshore as well as significant resources onshore. The 2016 update to the Clean Energy and Climate Plan had a goal of reducing 1990 baseline greenhouse gas emissions levels by 25% by 2020. Current goals include installing 3,500 MW of offshore wind power in the state by 2035. However as Q1 2020 the state had had only 119 megawatts (MW) of wind powered electricity generating capacity, responsible for generating 0.9% of in-state electricity production, with no new turbines under construction. The state has awarded contracts to two offshore projects, the 800 MW Vineyard Wind project and 804 MW Mayflower Wind project, which are still awaiting final federal regulatory approval as of April 2020.
The US state of Colorado has vast wind energy resources and the installed electricity capacity and generation from wind power in Colorado has been growing significantly in recent years. The growth has been sustained due to a combination of falling costs, continuing federal incentives, and the state's aggressive renewable portfolio standard that requires 30% of the state's electricity to come from renewable sources by 2020.
Solar power in Michigan has been growing in recent years due to new technological improvements, falling solar prices and a variety of regulatory actions and financial incentives, particularly a 30% federal tax credit, available for any size project. Although among the lowest U.S. states for solar irradiance, Michigan mostly lies farther south than Germany where solar power is heavily deployed. Michigan is expected to use 120 TWh per year in 2030. To reach a 100% solar electrical grid would require 2.4% of Michigan's land area to host 108 GW of installed capacity.
Wind power in Michigan is a developing industry. The industrial base from the automotive industry has led to a number of companies producing wind turbine parts in the state. The development of wind farms in the state, however, has lagged behind. In 2018, there were around a thousand wind turbines in the state with a nameplate capacity of 1,925 MW. The nameplate total exceeded 2,000 MW when Pine River came online in March 2019. Wind provided 4.2% of the state's electricity in 2016.
The state of South Dakota is a leader in the U.S. in wind power generation with over 30% of the state's electricity generation coming from wind in 2017. In 2016, South Dakota had 583 turbines with a total capacity of 977 megawatts (MW) of wind generation capacity. In 2019, the capacity increased to 1525 MW.
Renewable energy in Taiwan contributed to 8.7% of national electricity generation as of end of 2013. The total installed capacity of renewable energy in Taiwan by the end of 2013 was 3.76 GW.
The U.S. state of Connecticut has vast wind energy resources offshore as well as onshore although Connecticut was the last state in the United States to block the construction of utility scale wind turbines. Connecticut maintains a Renewable portfolio standard that requires 21% of the state's electricity to come from renewable sources by 2020. In 2019, the state awarded a contract to Vineyard Wind to develop offshore power.
