Blog post three. Geothermal energy

 Geothermal energy is when the heat from the sub-surface of earth is harnessed and used to create energy. This form of energy is renewable because the earth is always creating heat inside of itself. Some of its uses are bathing, heating buildings and generating electricity. Geothermal energy was first used in Italy in the year 1904 and is very consistent. It is used in over 20 countries, the United States being the largest producer of them. Another country who depends on geothermal energy is Iceland. They produce 25% of there energy from five geothermal power plants. There are very few cons to this though. It does produce very low levels of CO2 but also emits sulfur dioxide and hydrogen sulphide. They also create small tremors due to the fracking used to access the water or steam. I think this is definitely a better alternative than using coals and fossil fuels and it should be used more in our world today.
