Abstract
Geothermal energy is a form of renewable energy generated by tapping into the Earth’s internal heat. This heat is produced by the radioactive decay of minerals and the original heat of the Earth, which dates to its formation. There are several ways to generate electricity from geothermal energy: Dry steam power plants, flash steam power plants, and binary cycle power plants. Geothermal energy has several advantages as a source of electricity: It is reliable, relatively cheap to produce, and produces very low levels of greenhouse gas emissions. It is also a domestic energy source, reducing reliance on imported fossil fuels. This Data Insight will present trends in geothermal electricity and heat generation by region.
