The Earth is not Solid • The Earth is made in layers in which geothermal energy is produced in the core. • The first step in the organic creation of geothermal energy is that the core gets boiled until it releases a huge amount of energy, known as geothermal energy • It is then that the energy is pushed to the surface where it is released • The energy is spread throughout the atmosphere and is caught by man for our uses • This energy is renewable because it is organic, meaning coming from the earth • Geothermal energy is generated by heat stored beneath the earths surface
Geothermal is Renewable • Geothermal power plants don’t burn fuel to produce electricity, they just use the energy’s fuel cells to • Geothermal energy is eco-friendly because it is organic • It only release 1% of Carbon-dioxide into the atmosphere • It is amazing how it uses 97% of rainfall as one of its many power supplies • Geothermal energy supplies less than 10% of the word’s energy supplies • Geothermal energy is sustainable because water can be re-injected into the earths surface
Where is geothermal energy found? • Geothermal energy naturally occurs in large areas of hydrothermal resources as the form of volcanoes, geysers, or hot springs • These areas are also referred to as geothermal reservoirs • It can also be found underground which is one of the main reasons why mining started in North America • Most geothermal reservoirs are found near plate boundaries, especially in the Pacific Plate-Boundary • When magma makes contact to the surface, it heats the ground-water trapped on fractures and faults making hydrothermal resources which leads to the creation of geothermal reservoirs • The U.S has a massive supply of geothermal reservoirs which has been producing energy since 1960
We use geothermal energy • Geothermal energy has three main uses: Heating; Electricity generating; and geothermal heat pumps • Geothermal energy exploit uses three basic types of geothermal power plants: Dry steam, Flash steam and Binary power plant. • Geothermal energy is widely used in California with more than 30 geothermal power plants that are producing more than 90 % of the geothermal electricity in the USA. • Geothermal energy widely exploited in Iceland, New Zealand, Japan, Italy, Philippines and in USA mostly in California and Nevada.
Electricity • Geothermal energy is widely used in California with more than 30 geothermal power plants that are producing more than 90 % of the geothermal electricity in the USA. • Geothermal energy's amount of electricity is less than 1 percent of total electricity produced in the USA. • Geothermal energy is giving 18 % of Iceland's total electricity. • Geothermal energy could produce 10 percent of US electricity by the year 2050. • Geothermal energy could supply US with more than 30,000 MW of power by 2025. • Geothermal energy can be easily found and exploited along the "Ring of Fire" region. • Geothermal energy is extremely efficient (almost 100 %) energy source where only real source of losing energy is from turbine friction.Geothermal energy has only one real problem and that is lack of easily accessible sites.Geothermal energy's advantage is also the fact that geothermal power plants run continuously day and night with an uptime typically exceeding 95%.
