What is geothermal energy
How does geothermal energy work.
Geothermal Energy
A geothermal heat pump system can take advantage of the constant temperature of the upper ten feet (three meters) of the Earth’s surface to heat a home in the winter, while extracting heat from the building and transferring it back to the relatively cooler ground in the summer.
Geothermal water from deeper in the Earth can be used directly for heating homes and offices, or for growing plants in greenhouses.
Some U.S. cities pipe geothermal hot water under roads and sidewalks to melt snow.
Production of Geothermal Energy
To produce geothermal-generated electricity, wells, sometimes a mile (1.6 kilometers) deep or more, are drilled into underground reservoirs to tap steam and very hot water that drive turbines linked to electricity generators.
The first geothermally generated electricity was produced in Larderello, Italy, in 1904.
There are three types of geothermal power plants: dry steam, flash, and binary. Dry steam, the oldest geothermal technology, takes steam out of fractures in the ground and uses it to directly drive a turbine.
