I will be telling you about the renewable energies.
Solar power has amazing potential. If we were to add up the amount of solar energy that is absorbed by the earth's atmosphere, land, and oceans it would add up to approximately 3,850,000 EJ (Exajoules). Some of the benefits of using this kind of energy is that it will be renewable for quite some time plus it stops putting harmful chemicals into rivers and into the atmosphere and stops using up fossil fuels.
Geothermal power is clean, reliable and cost effective but its availability is often limited to areas near tectonic plate boundaries. As of 1010, 24 countries around the world use geothermal power to generate electricity while around 70 use it for various forms of heating. One of the benefits of using this energy is that the earth will always be heated as long as it stays going it will always be a renewable energy just like solar power.
Tidal Power is the use of the rise and fall of tides involving very large volumes of water at low heads to generate electric power. The tide moves a huge amount of water twice each day and although the tidal energy supply is reliable and plentiful, converting it into useful electrical power is not easy. One benefit of using this type of power is there will always be tides so we can always have tidal power.
Wind turbines are big. A wind turbine blade can be up to 260 feet long, and a turbine tower can be over 328 feet tall taller than the Statue of Liberty.
One of the benefits of using this power is that there will pretty much always be wind somewhere so we will have lots of power.
