The renewable-energy industry is the part of the energy industry focusing on new and appropriate renewable energy technologies. Investors worldwide are increasingly paying greater attention to this emerging industry.

Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries.

China is the world's top electricity producer from renewable energy sources. China's renewable energy capacity is growing faster than its fossil fuels and nuclear power capacity.

100% renewable energy is the goal of using fully renewable resources for all electric energy consumption. 100% renewable energy for electricity, heating, cooling and transport is motivated by greenhouse gas emissions, pollution, and other environmental issues, as well as economic and energy security concerns.

The Centre for Renewable Energy Systems Technology (CREST) is a research centre into renewable energy based in the Department of Mechanical, Electrical and Manufacturing Engineering, Loughborough University in England.

Renewable energy in Mexico contributes to 26 percent of electricity generation in Mexico. As of 2009, electricity generation from renewable energy comes from biomass, hydro power, geothermal, solar power and wind.

Renewable energy in the United Kingdom refers to energy from renewable sources used for electricity generation, heat and transport in the United Kingdom. In 2024, renewables accounted for 50.4% of UK electricity generation and 16.2% of gross final energy consumption.

The International Renewable Energy Agency (IRENA) is an intergovernmental organization mandated to facilitate cooperation, advance knowledge, and promote the adoption and sustainable use of renewable energy. It is the first international organization to focus exclusively on renewable energy, addressing needs in both…

Variable renewable energy (VRE) or intermittent renewable energy sources (IRES) are renewable energy sources that are not dispatchable (adjustable on demand) due to their fluctuating nature, such as wind power and solar power, as opposed to controllable renewable energy sources, such as dammed hydroelectricity or…

Renewable energy in Germany comes mainly from wind power, solar power and biomass and is a central component of the country's Energiewende. In 2025, renewable sources accounted for 23.8% of Germany's gross final energy consumption.
