And for geothermal energy – power – to be sustainable, these reservoirs must be properly managed. As such, geothermal energy is entirely renewable as an energy source. The temperature at Earth’s core measures close to 7200 degrees Fahrenheit. 2  Geothermal energy comes with “some” environmental issues. 4  Geothermal energy production is location specific. Thus, the amount of geothermal power we will use in future will depend upon technological advancements, on politics (the mount of subsidies), and on energy prices in general. 1  Geothermal energy comes from a renewable resource.

What are the Advantages and the Disadvantages of Being an ESL Teacher?

I was writing an essay on geothermal energy, and this site helped me so much! Energy supplies from geothermal reservoirs will persist for a few billion years from now. Nevertheless, over a period of many years, there’s every chance that geothermal heating and cooling systems will save money. For now, it’s a scenario that is very difficult to predict. Advantages of Geothermal Energy 1) It is a renewable source of energy. <> Geothermal heat pumps work in a very similar fashion to electrical heat pumps. Geothermal Energy Sourcing Is Good for the Environment. As such, using a geothermal heat pump to tap this source makes for an excellent heat sink or heat source. On a commercial scale, projects involving geothermal power are costly. What are the Advantages and the Disadvantages of Owning a Bar? Geothermal heat pumps can also be used to tap into heat sinks/ sources. :). Geothermal energy resources range from very shallow ground just below our feet through to hot rock and hot water that is located well below the surface of the Earth, quite a few miles down. Advantages of Geothermal Energy 1) It is a renewable source of energy. After this, it is pumped into the interior delivery system. 2 0 obj In the summer, heat that is removed from inside the building can be utilized as a way of providing hot water inside the building. Currently, geothermal power plants worldwide provide around 10,715 megawatts (MW) of electricity. There are some countries such as Iceland and the Philippines (both countries meet almost a third of their entire electricity demands using geothermal energy) that have been blessed with excellent geothermal resources. As such, geothermal energy is entirely renewable as an energy source. Once technology provides a more efficient form of transportation or storage for the energy produced, and eliminates some of the dangers, and the problems around distance from market, then this method will be far more attractive. Construction of geothermal energy plants can affect the seismic stability to a large extent. Geothermal power plants have a minimal carbon footprint and the development of resources for geothermal energy harvesting is seen as beneficial in terms of fighting against global warming. stream 3  Geothermal energy production has huge potential. The fluid within geothermal reservoirs can become depleted should the fluid be removed more quickly than it is replaced. This amount is much less than the current capacity of installed geothermal heating which stands at 28,000 MW. The pro's and cons you have mentioned here are spot on. Solar Energy vs. Wind Energy - Which is Best? When geothermal power plants are constructed it can impact the surrounding land’s stability. Although it is a one-time investment, geothermal energy can burn quite a big hole in a customer’s pocket. Geothermal Energy : Advantages And Disadvantages. Near to geothermal power plants, the emissions of greenhouse gases have a tendency to be far higher than normal. A typical geothermal power plant emits approximately 122kg of carbon dioxide per megawatt-hour (MWh) of electricity generation. Natural resources are responsible for the creation of geothermal reservoirs. 1 0 obj It is a non-polluting and environment-friendly generating source of energy. On an annual basis, the estimate is that we can harvest anything between 0.035 and 2 TW from geothermal power plant production. What are the Advantages and the Disadvantages of Owning a Dog? Advantages and Disadvantages of Hydro electricity, Creative Commons Attribution-NoDerivs 3.0 Unported License. Permanent power supply. This is the number one reason why this energy is used in various applications. Should geothermal energy be transported over long distances as hot water, and not as electricity, there will, of course, be a significant amount of energy loss. : The largest single disadvantage of geothermal energy is that it is location specific. Very many homeowners now utilize this method to heat and to cool their homes. 4  Geothermal energy is ideal for heating and for cooling. Compare that to a typical coal power plant and it’s 1/8th (one eighth) of the amount of carbon emission. 1  Geothermal energy has issues of sustainability. : Gases are released into the atmosphere during digging. %���� In turn, these reservoirs are, likewise, naturally replenished. Emissions of silica and sulfur dioxide are commonplace near geothermal plants, while geothermal reservoirs may consist of various toxic heavy metals, inclusive of boron, arsenic and mercury.
