Biofuel has to be burnt. The heat is used to produce steam which turns electricity turbines, in much the same way as fossil fuels (coal, oil and natural gas) power stations. This burning releases carbon dioxide, but this is a recent recycling of the gas, with no carbon footprint.
None of the other three Is burnt.
* Solar uses photovoltaic panels or focussing mirrors.
* Wind uses the motion of the wind, like hydro power.
* Geothermal uses the existing heat from under the earth to produce the steam.

What are the types of renewable energy?
Wind energy, hydropower , solar energy biomass, biofuel, geothermal energy
What is the main renewable energy resources?
Renewable energy: (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel).
What are examples of a renewable source of energy?
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen).
What forms of energy are renewable resources?
Renewable energy (solar, wind, water (hydro, tidal and wave), geothermal, ocean thermal, biomass, biofuel and hydrogen).
What are 6 forms of renewable energy resources?
Renewable energy (solar, wind, water (hydro, tidal and wave), geothermal, ocean thermal, biomass, biofuel and hydrogen).
What is the energy resource that can be used in place of fossil fuels?
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen).
What energy sources produce no greenhouse gasses?
Renewable energy sources produce no greenhouse gases.Examples are solar, hydro, wind, wave, tidal, geothermal, biomass, biofuel and others.
Is Geothermal the same as Solar. If it is not the same then what is Geothermal?
Geothermal energy is not the same as solar energy- geothermal refers to heat generated by the earth, not the sun.
How does nuclear energy use differ from geothermal and solar energy use?
Nuclear energy uses fission reactions to generate heat for electricity production, while geothermal energy uses heat from the Earth's core and solar energy uses sunlight to directly generate electricity. Both geothermal and solar energy are considered renewable sources, whereas nuclear energy produces radioactive waste that requires careful disposal. Additionally, nuclear energy plants are more complex and costly to build compared to geothermal and solar energy systems.
What are six things that are renewable energy sources?
Renewable energy comes in many forms. Its main advantage is its non-polluting contribution to our energy supplies.solar,wind,hydro,tidalwave,geothermal.
Is geothermal energy solar energy?
no
What are alternatives to oil and natural gas?
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel). coal,wood
