Question

Which are renewable energy resources?

Answer 1

Renewable resources of energy:

• Sunlight, wind, tidal, geothermal heat are renewable energy resources. These energy resources can be replenished in a short period of time.
• Renewable energy sources are replenished constantly by sunlight, aside from geothermal and tidal energies. Uneven solar heating of the Earth's surface causes wind.
• Sunlight also fuels the water cycle, which is harnessed through hydropower. Biofuels are grown using sunlight.
• Geothermal energy is considered renewable because radioactive decay in the Earth's core, which isn't expected to cool down any time soon, produces it. The gravitational pull of the sun and moon causes the tides.
