In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump.
Weegy: Geothermal heating is the direct use of geothermal energy for heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. [ Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption.[1] Thermal efficiency is high since no energy conversion is needed, but capacity factors tend to be low (around 20%) since the heat is mostly needed in the winter. ] User: Describe the process of generating geothermal electricity by outlining the steps involved. Take your description from the drilling for hot water stage to the electricity production stage. Weegy: Heat from under the ground is used to make steam. This steam is used to spin turbines to generate electricity. [ A: In every energy-making process that involves burning a fuel (like coal or wood) the result is that the heat of that burn is used to create steam which is sent through a turbine, which spins a generator that is connected to said turbine. What geothermal energy does is replace the coal or wood, with the hot spot/hot spring, so it is used to make steam and make power. A: Geothermal is one of the sources of electricity and one of the safest, how does geothermal work, let me tell you how it works. First they need to find a hot spot, this is where there is hot fluid under the ground, the hot fluid is rain water collected over the years then the magma heats it up, but sometimes the hot spots are dead for years maybe even decades this is a con about geothermal. First they drill wells into the ground and get hot fluid which is about a 5-10 thousand feet under the ground. Then magma will flow up the pipe due to pressure under the ground, and then the pressure is lessened then turns some of the magma into steam then the steam goes to a different pipe. Then the remaining hot fluid goes ... (More)

In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump. In two or three sentences, explain where geothermal energy comes from and why we have to drill so far down to access superheated fluids. Describe the process of generating geothermal electricity by outlining the steps involved. Take your description from the drilling for hot water stage to the ...
