When considering the various sources of renewable energy that would help reduce the United States’ dependence on fossil fuels, a lot of thought should be offer to geothermal energy. Geothermal energy is entirely clean and will not pose the health risks associated with the harvesting, use, and burning of fossil fuels. It is an inexpensive and sustainable choice, one thing that should be given great thought as a viable alternative.
Geothermal energy is merely the heat given off by the earth itself. The core of the earth contains a layer of magma that regularly produces heat. This heat is produced by the decay of radioactive materials such as uranium, and over fifty thousand times additional energy than contained by all of our oil and natural gas resources will be found in solely a thirty three,000 foot radius of the world’s surface.
Currently, the most common methodology of harvesting geothermal energy is by tapping into geothermal springs. In these springs, cooler water seeps into the bottom, only to be heated through convection and rise to the surface as steam. This steam is collected and used to power electricity generators. Several power plants drill into the planet in order to capture steam additional effectively and in bigger quantities.
Several geothermal reservoirs have been discovered across the globe, every with the capability to provide as a lot of energy as a thousand wind power plants. There is currently a lot of research taking part on a world scale to find effective and safe ways in which to faucet into and utilize this energy. The most important hindrance to mass geothermal energy use has been the buildup of silica within wells at geothermal power plants. Because researchers have recently found ways in which to help control this pricey downside that has long been the largest barrier to widespread use of geothermal energy, there’s abundant hope that this manner of energy can finally receive the eye and consideration it deserves.
With the discovery of a means to control silica buildup comes the hope that the energy committees can invest additional analysis and cash into geothermal energy, which promises to be both cheap and one of the cleanest energy sources available. Over sixty million people worldwide receive their electricity from geothermal power plants, with over four million of these folks residing in the United States. Supporters of geothermal business hope to determine that number rise significantly in the approaching years, as the process becomes additional economical in regards to both finances and energy production.
In brief, tapping into the planet to reap geothermal energy is by so much one among the foremost sustainable methods of acquiring energy available. The earth’s core could be a constant provide of energy, with no risk of depletion and no harmful emissions. Abundant research ought to be place into geothermal energy to seek out the best potential ways of bringing the technology to the greatest range of individuals, creating energy independence and eliminating the necessity for fossil fuels in the assembly of electricity.
