How do engineers use earth's heat to create geothermal energy?

Answer 1

There are three main ways engineers use geothermal energy. 1.Direct heating systems-hot water is piped into buildings to provide heat. 2.Geothermal power plants0-use resourced from dry steam wells and hot water wells. wells one to two miles deep are dug and hot water and steam are piped to the surface. Steam or a liquid turned into steam, turn the turbines. 3.Geothermal heat pumps transfer heat from the ground or water into buildings in the winter and reverse in the summer.

Answer 2

In regions where volcanoes are or were active hot molten magma lies under ground. And when water is also present in those same regions that water can be turned into steam or simply very hot water.

That steam can be accessed by drilling down to where it's formed and venting that steam up to turbines that drive electrical generators. And there the geothermal energy as steam in converted into grid electrical power to distribute to users in the region.

Calistoga CA has geothermal generated electrical power for example. That area is also noted for its hot springs and mineral waters for spas.

Answer 3

Engineers use geothermal energy by drilling wells into the earth to tap into hot water and steam reservoirs deep underground. This hot water and steam is then brought to the surface to drive turbines that generate electricity. The energy created from the heat of the earth can be used for heating buildings or generating electricity.
