= Geothermal Energy: Know How = by: Hannah

===[|Geothermal energy] is a very good source of energy. There are no fossil fuels that need to be put into the plants. It is an almost 100% clean energy source. It also gives off no green house gases. It is very good for the environment. It is also considered a renewable energy source. In Reykjavik, Iceland, 95% of all of the buildings are heated with geothermal energy. ===

===One way you can use geothermal energy is with geysers. It costs three cents per kWh for geothermal energy from geysers. Another way is by drilling. You can usually find a place to drill on major plate boundaries. The most common area to find geothermal energy is along the ring of fire. ===



===There is also another way. If you want to heat an individual building of home, you start by drilling a large hole under the house, building, etc. Then, pipes are installed. They are then filled with heat absorbing fluid. In the winter, when inside the earth is warmer, the heat is absorbed into the pipes and brought up to the home. In the summer, when the inside of the earth is cooler, heat is absorbed from the house into the pipes and is stored. It is cooled inside the earth and will cool the house. ===

=== You can use hot water and steam as geothermal energy, too. Electricity from power plants uses hot water and steam from springs, geysers, etc. You can get hot water from geothermal springs or reservoirs. Geothermal energy is a good form of renewable energy because it doesn't need fossil fuels to run it. It also good because it doesn't give of any green house gases. ===
