What is geothermal energy? - Power Technology ~ Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma. To produce power from geothermal energy, wells are dug a mile deep into underground reservoirs to access the steam and hot water there, which can then be used to drive turbines .
Energy 101: Geothermal Energy / Department of Energy ~ Heat from the earth's crust warms water that has seeped into underground reservoirs. When water becomes hot enough it can break through the earth's surface as steam or hot water. This usually happens where the earth's crust or "plates" meet and shift.

Geothermal energy is derived from the natural heat of the earth. 1 It exists in both high enthalpy (volcanoes, geysers) and low enthalpy forms (heat stored in rocks in the Earth’s crust). Nearly all heating and cooling applications utilize low enthalpy heat. 2 Geothermal energy has two primary applications: heating/cooling and electricity generation. 1
How Geothermal Energy Works / Union of Concerned Scientists ~ Geothermal heat occurs everywhere under the surface of the earth, but the conditions that make water circulate to the surface are found in less than 10 percent of Earth's land area. An approach to capturing the heat in dry areas is known as enhanced geothermal systems (EGS) or "hot dry rock". The hot rock reservoirs, typically at greater depths below the surface than conventional sources, are .
Use of geothermal energy - U.S. Energy Information ~ Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik, Iceland.

Environmental Impacts of Geothermal Energy / Union of ~ The amount of land required by a geothermal plant varies depending on the properties of the resource reservoir, the amount of power capacity, the type of energy conversion system, the type of cooling system, the arrangement of wells and piping systems, and the substation and auxiliary building needs . The Geysers, the largest geothermal plant in the world, has a capacity of approximately 1,517 .
Geothermal power plants - U.S. Energy Information ~ Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal). Geothermal power plants require high-temperature (300°F to 700°F) hydrothermal resources that come from either dry steam wells or from hot water wells. People use these resources by drilling wells into the earth and then piping steam or hot water to the surface. The hot water or steam powers a .
A Complete Guide to 7 Renewable Energy Sources / SunPower ~ Geothermal: Power from the Earth. Geothermal energy is derived from the heat of the earth. This heat can be sourced close to the surface or from heated rock and reservoirs of hot water miles beneath our feet. Geothermal power plants harness these heat sources to generate electricity. On a much smaller scale, a geothermal heat pump system can .
Environment for Kids: Renewable Energy ~ Renewable energy uses energy sources that are not "used up". For example, solar power from the sun is renewable as we won't "use up" all the sunlight from the sun. Examples of non-renewable energy sources include fossil fuels like coal and oil. Once we use or burn these resources, they are gone forever. Why is renewable energy important? Much of the world relies on non-renewable energy to heat .
What Are Examples of Renewable Energy Sources? - WorldAtlas ~ Renewable energy sources are typically used as substitute energy.
