Geothermal Energy

What is Geothermal Energy?

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. This heat can be harnessed to generate electricity using steam or hot water that is extracted from the earth's crust.

How is Geothermal Energy Formed?

Geothermal energy is formed from the decay of radioactive materials in the earth's crust. The heat produced during this process can reach temperatures of over 700° F (370° C) at the earth's core.

Uses of Geothermal Energy

Geothermal energy is used for various purposes, including generating electricity and providing heating for residential, commercial, and industrial buildings. It can also be utilized for greenhouse agriculture, aquaculture, and spas.

Advantages of Geothermal Energy

Renewable and Sustainable
Low Emissions
Constant and Reliable
Low Operating Costs

Disadvantages of Geothermal Energy

Location Specific
High Initial Costs
Surface Instability
Limited Lifetime of Wells

What is science?

The resources above cover the following skills:

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).

EARTH AND SPACE SCIENCE

Earth’s Systems

Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
