The main renewable sources of energy to generate electricity are:
- hydropower (use of water from rivers, dams, tides and ocean waves)
- wind energy (using wind turbines)
- solar power (using the power of the sun to heat water or produce electricity)
- geothermal (using the heat deep under the earth's crust)
- ocean Thermal (using surface heat and deep cold water)
- biofuel (producing ethanol from organic material like switch-grass, corn and sugar cane husks)
*Strictly speaking an energy source is not 'renewable' if you mean "can humanity restore it?", as it must with trees, for example.
Geothermal, for example, is self-renewing - the Earth is constantly giving off its heat to water which is close enough to the heat to be warmed by it. It is not diminished to any noticeable extent by our using it. It is possible to use a geothermal resource to capacity locally. One example is in the geothermal area of Rotorua, New Zealand, where too many thermal bores resulted in the decline of the geysers that were a tourist attraction. This has since been addressed by controls on the bores in the area, and the geysers are performing as before.
Heat or light from the sun, wind (turns turbines which produce electricity), and water (the power of the flow turns turbines which produce electricity).

What else can I help you with?
Is electricity renewable or non renewable?
Electricity is a non-renewable resource. Once you have used it, it won't come back. You have to generate more.You can generate electricity in any number of ways. You can use solar cells, wind power, water falling through turbines, you can burn coal, oil, natural gas, etc. You can generate electricity by running on treadmills or using stationary bikes. It's all electricity, but some of the methods use renewable sources and others do not.A: If electricity is produced by solar, wind, tides, waves, biomass, or geothermal energy then it is a renewable resource. Otherwise it is not.A: Electricity is largely produced by power stations burning fossil fuels like coal, oil, and natural gas; Nuclear fission can also be used to produce electricity. All these are not renewable - there is a finite amount of fuel in the world and when it is used up, that's it.Hydro, wind, tidal, geothermal, biomass, and solar power are all regarded as renewable forms of energy because they aren't finite. We use their energy, and it still keeps coming.
Is energy resource or nonrenewable?
Energy can be both a resource and nonrenewable. Renewable energy sources such as sunlight and wind are resources that can be naturally replenished. Nonrenewable energy sources like fossil fuels (coal, oil, natural gas) are finite and formed over millions of years, making them nonrenewable.
What are some alternatives of geothermal energy?
Some alternatives to geothermal energy include solar power, wind energy, hydroelectric power, and biomass energy. These sources of renewable energy offer environmentally-friendly options for generating electricity and are becoming increasingly popular as the world shifts towards cleaner energy sources.
What energy resources are found above the earths surface?
Some examples of energy resources found above Earth's surface include solar energy, wind energy, and hydropower. These resources provide renewable and sustainable sources of energy that can be harnessed for electricity generation and other purposes.
What are facts about renewable and non renewable energy?
Renewable energy is less harmful to the environment compared to Non renewable energy.Some renewable energies include solar,Geothermal,wind,water and biomass,which can be made up of sewage.** Some non renewable energies are coal, natural gas,oil and nuclear.
If an energy source is nonrenewable?
some energy sources are non renewable but some are renewable
What are some source of energy other than electricity?
Some sources of energy other than electricity include fossil fuels (such as coal, oil, and natural gas), renewable sources (such as solar, wind, hydro, and geothermal energy), and biomass (such as wood and biofuels). These sources can be used to generate electricity, but they can also be used directly for heating, transportation, and other applications.
Is kinetic energy renewable?
it never runs out
What are the types of modern energy?
Some types of modern energy include renewable energy sources like solar, wind, hydroelectric, and geothermal energy, as well as non-renewable sources like fossil fuels such as coal, oil, and natural gas. Nuclear energy is another type of modern energy that is used for electricity generation.
What are the sources of the energy you use every day?
The main sources of energy used every day include fossil fuels (such as oil, coal, and natural gas) for transportation and electricity generation, renewable sources like solar and wind for electricity production, and nuclear power for electricity generation. Additionally, some energy comes from biomass (such as wood and plant waste) for heating and cooking purposes.

What are some simularities of the sun's energy and the wind?
They are both seen as renewable sources of energy
What are some Types of secondary energy resources?
Some types of secondary energy resources include electricity, hydrogen, and compressed air. These resources are produced using primary energy sources such as coal, natural gas, and renewable sources like solar and wind energy.
Is energy resource or nonrenewable?
Energy can be both a resource and nonrenewable. Renewable energy sources such as sunlight and wind are resources that can be naturally replenished. Nonrenewable energy sources like fossil fuels (coal, oil, natural gas) are finite and formed over millions of years, making them nonrenewable.
How does renewable energy save money?
Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
If renewable resources can be replaced why do we need to conserve them?
The wind and the sun and moving waters are all renewable energy sources. We really do not have to conserve them.At present much of our electricity is generated from fossil fuels, producing extra carbon dioxide emissions and causing global warming and climate change, so it is important to conserve electricity. Conserving electricity will reduce these harmful emissions.When all our energy is produced from renewable sources and we are no longer burning fossil fuels (some time in the future), then electricity will be cheaper (or completely free), and conserving electricity will not be as important.
What are some renewable sources of energy besides solar wind and water?
Some other renewable sources of energy include geothermal energy, which comes from heat within the Earth's crust, and biomass energy, which is derived from organic materials like wood or agricultural waste. Another source is tidal energy, which harnesses the power of ocean tides to generate electricity.
