Other renewables
Other well-established renewable energy forms include hydropower, bioenergy and geothermal energy.
- Hydroelectricity is electricity generated by hydropower and plays a leading role in countries like Brazil, Norway and China. but there are geographical limits and environmental issues. Tidal power can be used in coastal regions.
- Bioenergy can provide energy for electricity, heat and transport. Bioenergy, in particular biogas, can provide dispatchable electricity generation. While burning plant-derived biomass releases CO
2, the plants withdraw CO
2 from the atmosphere while they grow. The technologies for producing, transporting and processing a fuel have a significant impact on the lifecycle emissions of the fuel. For example, aviation is starting to use renewable biofuels. - Geothermal power is electrical power generated from geothermal energy. Geothermal electricity generation is currently used in 26 countries. Geothermal heating is in use in 70 countries.
