It is a story which is only going to receive more attention and grow larger in importance as the ecological and economic consequences of fossil fuels become clearer. Geothermal energy is most commonly referred to as a green energy source. However, funding such a revolution, in terms of technology and equipment, could still be quite costly. This has many positive implications, notably that geothermal power is an appropriate source for meeting baseload energy demand. This is because, unlike wind, solar, and hydropower, geothermal energy comes from within the earth, and we don’t need to build out collection setups over large swaths of land surface to harness it. That said, while this isn’t an idle concern, the amount of heavy metals and greenhouse gasses produced by current geothermal processes are far less damaging on the whole than fossil fuels, given the latter’s production of greenhouse gasses. That is the kind of info that are meant to be shared around the net. The underground rock and water is heated this way and can reach a temperature up to 700 °F (370 °C). Geothermal reservoirs above 100°C are usually necessary for most large geothermal plants, and these reservoirs are only found in specific locations, usually near tectonic plate boundaries or hot spots. Meanwhile, according to the International Renewable Energy Agency, geothermal energy has grown in terms of global usage over the course of the past decade, with geothermal wells, dug miles deep into the Earth, allowing access to steam and reservoirs of hot water that can be used to generate electricity. This is why the vast majority of U.S. geothermal power plants are in California: the state lies close to an active fault zone that is part of the larget “ring of fire” around the Pacific Ocean. For reference, National Geographic estimates that a geothermal power plant capable of producing 1 gigawatt-hour (GWh) of electricity would take up approximately 404 square miles of land surface, while a wind farm at the same energy output would need about 1,335 square miles, and a solar farm would need about 2,340 square miles. As with any technology, the use of geothermal energy still faces several drawbacks, despite the significant advantages of pursuing geothermal. While it is by no means without flaws, by every conceivable metric, geothermal energy compares favorably against traditional fossil fuels in terms of the impact each has on the environment. Given the rate at which sea levels and temperatures are rising, putting low-lying cities around the world at risk and already causing climate change on a global scale, oil and coal cannot continue to be used in the manner they are now without severe risk of further and irreparable global environmental harm. higher! Geothermal energy, meanwhile, is only slightly more expensive at $0.10 per kilowatt hour, with wind energy sitting at $0.13 per kilowatt hour. On number 5 of our geothermal energy pros and cons we have land footprint. I write about the renewable energy sector, electric cars and climate change issues. The approximate land usage of geothermal plants ranges between 53 and 367 acres. One proposed alternative is geothermal energy. The emissions of a geothermal plant, according to the United States Energy Information Administration, may even be as much as 99 percent lower than a fossil fuel plant of the same size (EIA, 2019). The price of fossil fuels can go up and down, the outside weather could be sunny or cloudy, but the price of geothermal power will remain the same and may even drop if the electricity generation capacity from geothermal energy will increase. This is no longer the case, with green energies like geothermal, as well as wind and solar, becoming more affordable while taxes are levied against oil and coal producers. While the process at present is not without some degree of CO2 emissions, at present, this does not pose the same kind of overwhelming threat to the environment as do fossil fuels. Geothermal energy as we know it first arose in Italy during the early 20th century. Will Carbon Capture Save the Fossil Fuel Industry? To become 100% green at home, installing a solar panel system will produce enough energy to power your geothermal heat pump and also a few household appliances.
