| Most people are not aware of geothermal energy, | | | | - Constant energy ensures large capacities can be |
| how it works, and the role it will play in our energy | | | | met |
| future. Although it is one of the lesser known | | | | - Heat extraction is negligible thus unending/sustainable |
| renewable energy sources it is still a viable alternative. | | | | energy source |
| In both the Philippines and Iceland nearly a quarter of all | | | | - Land usage is extremely small |
| energy produced is geothermal electricity. These | | | | - Scalable depending on demand for geothermal |
| countries have shown that such systems are | | | | electricity |
| completely feasible and in fact quite efficient. | | | | Disadvantages of Geothermal Power |
| Electricity is generated by extracting water from | | | | - Vapor fluid is corrosive and hard to manage |
| underground which has been heated by magma. This | | | | - Fluid is kept at low temperature limiting heat engine |
| water is then run next to pipes containing a fluid with a | | | | production |
| lower boiling point than the water. The water causes | | | | - Small amount of carbon dioxide / sulfur emission |
| the fluid to boil turning it into a vapor which then | | | | - Location could cool down after years of use |
| powers turbines. These turbines are the source of | | | | depending of water reserve |
| geothermal electricity which is then used to power | | | | Even though it isn't as well known as a lot of the other |
| homes and businesses. | | | | renewable energy sources the future is bright for this |
| Here are a few geothermal energy facts: | | | | innovative and efficient method of harnessing the |
| Advantages of Geothermal Power | | | | power of nature to do work. Some technological |
| - Only fuel is heated underground water thus its | | | | advances in turbines could make these power plants |
| emission free | | | | even more efficient in the future. |
