Expand the use of geothermal energy as a global source for heating, cooling, and electricity.
Geothermal is a nearly unlimited source of renewable energy. It is the heat left over from the formation of the Earth and the decay of radioactive materials within the Earth’s core. This heat can be tapped as a form of baseload energy without interruption, unlike wind or solar power. Geothermal can directly heat buildings, warm and cool with heat pumps, or can be used to power turbines with steam, generating electricity. Geothermal plants and technologies produce minimal greenhouse gas emissions. Despite these benefits, geothermal currently supplies under 1 percent of global energy. This is changing, however, as technological advancements accelerate its potential for wider use. Further research, as well as expanded investment in proven systems, are essential to ensure that geothermal is successfully scaled up as a major source of energy worldwide.
