Renewable energy in Germany is mainly based on wind and biomass, plus solar and hydro. Germany had the world's largest photovoltaic installed capacity until 2014, and as of 2023 it has over 82 GW. It is also the world's third country by installed total wind power capacity, 64 GW in 2021 and second for offshore wind, with over 7 GW. Germany has been called "the world's first major renewable energy economy".
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. In 2019, nearly 75% of new installed electricity generation capacity used renewable energy and the International Energy Agency (IEA) has predicted that by 2025, renewable capacity will meet 35% of global power generation.
For solar power, South Asia has the ideal combination of both high solar insolation and a high density of potential customers.
Solar power accounted for an estimated 10.7% electricity in Germany in 2022, up from 1.9% in 2010 and less than 0.1% in 2000.
A feed-in tariff is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above-market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage the development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "digression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions.
Hermann Scheer was a Social Democrat member of the German Bundestag (parliament), President of Eurosolar and General Chairman of the World Council for Renewable Energy. In 1999, Scheer was awarded the Right Livelihood Award for his "indefatigable work for the promotion of solar energy worldwide".
Feed-in electricity tariffs (FiT) were introduced in Germany to encourage the use of new energy technologies such as wind power, biomass, hydropower, geothermal power and solar photovoltaics. Feed-in tariffs are a policy mechanism designed to accelerate investment in renewable energy technologies by providing them remuneration above the retail or wholesale rates of electricity. The mechanism provides long-term security to renewable energy producers, typically based on the cost of generation of each technology. Technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting higher costs.
The Energy Watch Group (EWG) is an international network of scientists and parliamentarians. The EWG conducts research and publishes studies on global energy developments concerning both fossil fuels and renewables. The organization states that it seeks to provide energy policy with objective information.
Joachim Luther received his PhD in experimental physics at the Leibniz University Hannover in 1970.
The Renewable Energy Sources Act or EEG is a series of German laws that originally provided a feed-in tariff (FIT) scheme to encourage the generation of renewable electricity. The EEG 2014 specified the transition to an auction system for most technologies which has been finished with the current version EEG 2017.
Rolf Disch is a German architect, solar energy pioneer and environmental activist. Born in Freiburg im Breisgau, Germany, Disch has dedicated particular focus to regional renewable and sustainable energy.
Ursula Sladek is a German environmentalist, founder and former president of Schönau Electricity Works, a "registered cooperative society" under German Law in Schönau, Germany, that provides electricity from renewable sources.
Renewable energy has developed rapidly in Italy over the past decade and provided the country a means of diversifying from its historical dependency on imported fuels. Solar power accounted for around 8% of the total electric production in the country in 2014, making Italy the country with the highest contribution from solar energy in the world that year. Rapid growth in the deployment of solar, wind and bio energy in recent years lead to Italy producing over 40% of its electricity from renewable sources in 2014.
Fonroche Énergie is a French company, founded in 2008 by Yann Maus. Its headquarters are in Roquefort, Lot-et-Garonne, in the French department of Lot-et-Garonne. Its core business is renewable and alternative energy.
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.
Renewable energy in Armenia ranges from geothermal, hydroelectric, solar and wind energy in Armenia.
Ministry of Energy, New and Renewable Energy Maharashtra or MAHAURJA is a ministry of Government of Maharashtra. The Ministry is currently headed by Devendra Fadnavis, a Deputy Chief Minister of Maharashtra and Cabinet Minister.
The energy sector in Tunisia includes all production, processing and, transit of energy consumption in this country. The production involves the upstream sector that includes general oil and gas, the downstream sector that includes the only refinery in Tunisia and most of the production of natural gas, and varied electrical/renewable energies. Renewable energy has been a strong point of focus for Tunisia as they look to optimize their green energy sources and advance their developing country. The Tunisian government has partnered with Russia and France in hopes of establishing nuclear energy as a viable alternative to fossil fuels and taking up a nontrivial chunk of the energy production in Tunisia. This is expected to be accomplished in the 2020s.
