Many countries and territories have installed significant solar power capacity into their electrical grids to supplement or provide an alternative to conventional energy sources. Solar power plants use one of two technologies:
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.
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall.
Solar power represented a very small part of electricity production in the United Kingdom until the 2010s when it increased rapidly, thanks to feed-in tariff (FIT) subsidies and the falling cost of photovoltaic (PV) panels.
In Honduras, there is an important potential of untapped indigenous renewable energy resources. Due to the variability of high oil prices and declining renewable infrastructure costs, such resources could be developed at competitive prices.
Energy in Mexico describes energy and electricity production, consumption and import in Mexico.
In 2021 France reached a total of 18,676 MW installed wind power capacity placing France at that time as the world's seventh largest wind power nation by installed capacity, behind the United Kingdom and Brazil and ahead of Canada and Italy. According to the IEA the yearly wind production was 20.2 TWh in 2015, representing almost 23% of the 88.4 TWh from renewable sources in France during that year. Furthermore wind provided for 4.3% of the country’s electricity demand out of the 18.7% provided by renewables in 2015.
Wind power is a growing source of electricity in Poland. In 2019, wind was the second most important source of electricity produced in Poland, after coal, and accounted for about 10% of the electricity production.
China's electric power industry is the world's largest electricity producer, passing the United States in 2011 after rapid growth since the early 1990s. In 2019, China produced more electricity than the next three countries—U.S., India, and Russia—combined.
Wind power in Italy, at the end of 2015, consisted of more than 1,847 wind turbines with a total installed capacity of 8,958 megawatts. Wind power contributed 5.4% of Italy electricity generation in 2015 (14,589 GWh). Italy is ranked as the world's tenth producer of wind power as of the end of 2016. Prospects for Italian wind energy beyond 2016 were very uncertain.
Worldwide growth of photovoltaics has been close to exponential between 1992 and 2018. During this period of time, photovoltaics (PV), also known as solar PV, evolved from a niche market of small-scale applications to a mainstream electricity source.
India is world's 3rd largest consumer of electricity and world's 3rd largest renewable energy producer with 38% of energy capacity installed in the year 2020 coming from renewable sources. Ernst & Young's (EY) 2021 Renewable Energy Country Attractiveness Index (RECAI) ranked India 3rd behind USA and China. In November 2021, India had a renewable energy capacity of 150 GW consisting of solar, wind, small hydro power, bio-mass, large hydro, and nuclear. India has committed for a goal of 450 GW renewable energy capacity by 2030.
Enel Green Power S.p.A. is an Italian multinational renewable energy corporation, headquartered in Rome. The company was formed as a subsidiary of the power generation firm Enel in December 2008. It is present with assets in operation or under construction in 21 countries and carries out development activities in a further 5 countries on five continents generating energy from hydropower, wind, solar and geothermal sources. As of 2021, it manages a capacity of 54,2 GW and has over 1200 plants worldwide. From 4 November 2010 to 31 March 2016, the company was listed on the FTSE MIB index of the Milan Stock Exchange, as well as on the Madrid Stock Exchange and the Barcelona, Bilbao, and Valencia regional Stock Exchanges.
The electricity sector in France is dominated by its nuclear power, which accounted for 71.7% of total production in 2018, while renewables and fossil fuels accounted for 21.3% and 7.1%, respectively. France has the largest share of nuclear electricity in the world, and together with renewable energy supplies, this has helped its grid achieve very low carbon intensity.
The electric power industry in Japan covers the generation, transmission, distribution, and sale of electric energy in Japan. Japan consumed 995.26 TWh of electricity in 2014. Before the 2011 Fukushima Daiichi nuclear disaster, about one third of electricity in the country was generated by nuclear power. In the following years, most nuclear power plants have been on hold, being replaced mostly by coal and natural gas. Solar power is a growing source of electricity, and Japan has the third largest solar installed capacity with about 50 GW as of 2017.
South Africa has a large energy sector, being the third-largest economy in Africa. The country consumed 227 TWh of electricity in 2018. The vast majority of South Africa's electricity was produced from coal, with the fuel responsible for 88% of production in 2017. South Africa is the 7th largest coal producer in the world. As of July 2018, South Africa had a coal power generation capacity of 39 gigawatts (GW). South Africa is the world's 14th largest emitter of greenhouse gases. South Africa is planning to shift away from coal in the electricity sector and the country produces the most solar and wind energy by terawatt-hours in Africa. The country aims to decommission 34 GW of coal-fired power capacity by 2050. It also aims to build at least 20 GW of renewable power generation capacity by 2030. South Africa aims to generate 77,834 megawatts (MW) of electricity by 2030, with new capacity coming significantly from renewable sources to meet emission reduction targets. Through its goals stated in the Integrated Resource Plan, it announced the Renewable Energy Independent Power Producer Procurement Programme, which aims to increase renewable power generation through private sector investment.
The Polish energy sector is the sixth largest in Europe. The scale of energy consumption in 1996–2015 increased from 139,593 GWh to 161,438 GWh. According to the data of Polskie Sieci Elektroenergetyczne (PSE), electricity production in October 2020 amounted to 13,553 GWh; domestic consumption amounted to 14,798 GWh.
Solar power in Mexico has the potential to produce vast amounts of energy. 70% of the country has an insolation of greater than 4.5 kWh/m2/day. Using 15% efficient photovoltaics, a square 25 km (16 mi) on each side in the state of Chihuahua or the Sonoran Desert could supply all of Mexico's electricity.
Under its commitment to the EU renewable energy directive of 2009, France has a target of producing 23% of its total energy needs from renewable energy by 2020. This figure breaks down to renewable energy providing 33% of energy used in the heating and cooling sector, 27% of the electricity sector and 10.5% in the transport sector. By the end of 2014, 14.3% of France's total energy requirements came from renewable energy, a rise from 9.6% in 2005.
In 2018 Chile produced about 7% of its electricity from solar power. As of year end, it had 2137 MW of solar PV capacity. In July 2020 installed solar capacity had risen to 3104 MW, with another 2801 MW under construction. At the end of 2021 Chile was the 22nd country in the world in terms of installed solar energy.
