Geothermal Energy ““geo” means Earth geo” means Earth ““thermal” means Heatthermal” means Heat Heat from the earth is used to provide Heat from the earth is used to provide
steamsteam The steam is then used to turn turbinesThe steam is then used to turn turbines These turbines are used to power These turbines are used to power
generators which provide electricitygenerators which provide electricity

Where can we find it? The entire U.S. (and most other areas of the
world) are suitable for geothermal heat pumps.
Geothermal Energy can be found in Steam geysers, fumaroles, hot springs etc
The “ring of fire” is the pacific ocean
