Nellis Solar Power Plant at Nellis Air Force Base in the USA. These are some of the largest wind farms in the world, as of January 2010: Wind power accounts for approximately 19% of electricity generation in Denmark, 11% in Spain and Portugal, and 9% in the Republic of Ireland. Wind power is widely used in European countries, and more recently in the United States and Asia. Wind power capacity has expanded quickly to 743 GW in 2020, and wind energy production was about 5% of total worldwide electricity usage, and growing fast. Wind power market grows Main articles: Wind farm and List of large wind farms. Projections vary, but scientists have advanced a plan to power 100% of the world's energy with wind, hydroelectric, and solar power by the year 2030.

However, grid-connected PV increased the fastest of all renewables technologies, with a 60% annual average growth rate. More wind power was added during 2009 than any other renewable technology. For wind power and many other renewable technologies, growth sped up in 2009 relative to the previous four years. Growth of renewables įrom the end of 2004, worldwide renewable energy capacity grew at rates of 10–60% annually for many technologies. Renewable energy sources: wind, sun and biomass.
