An energy is said to be renewable (EnR abbreviated) when it is produced thanks to a source of energy that nature can renew. Renewable energies are solar energy (the sun), hydro (marine currents), wind (air masses), biomass (organic waste) and geothermal energy (the heat of the Earth). Renewable energy is therefore inexhaustible and helps to fight against global warming and the greenhouse effect by producing low polluting emissions.
In 2017, renewable energies accounted for 16.3% of gross final consumption in France. In 2017, they also represent the fourth largest source of primary energy after nuclear power, petroleum products and gas (source: General Commissariat for Sustainable Development - Key figures for renewable energies - Edition 2019).
