Geothermal ..taking thermal energy from the earth's core
Falling water ..rivers, ocean tides
Wave motion ..in ocean
Thermal cycles ..in water and air
Wind motion ..of air
Pressure changes ..in atmosphere
Solar radiation ..from the sun
Fossil fuels ..coal, oil, natural gas
Biomass ..trees, plants
Fission nuclear energy ..splitting atoms
Fusion nuclear energy ..combining atoms
Renewable energy is a source of energy that can never be exhausted. We can obtain renewable energy from the sun (solar energy), from the water (hydropower), from the wind (windmills), from hot dry rocks, magma, hot water springs (geothermal) and even from firewood, animal manure, crop residues and waste (Biomass).
