Answer:
Answer below
Step-by-step explanation:
Wind energy, once a turbine, is able to generate a lot of electricity quite easily. All it needs is to spin in order to generate electricity, and the wind does all of the work when it is present, making it pretty easy.
Wind is among the most unreliable sources, as it comes and goes consistently and there can be long gaps without any air movement at all.
Geothermal energy does not cause lots of air pollution. Air pollution is generally caused by the burning of carbon rich substances, and geothermal energy, no matter what method is being used, does not ever involve the burning of anything. It uses the natural heat of the earth to generate power, no additional burning.
Geothermal energy is not available everywhere. While it utilizes the heat of the Earth which is all connected to the core's radioactive decay, not everywhere has an equal amount of heat. Geothermal heat is extracted from geothermal fields, where heat is excessive. Things such as tectonic plate boundaries determine geothermal fields.
