Did you know that under the earth's surface lies hundreds of joules of potential energy?
Under the earths crust are wells of VERY hot water that can be tapped to provide energy. Here's the quick start to how this works What is Geothermal Energy?

Introduction

Geothermal Energy

Hello and welcome to Nathan Burke's Physics 212 web project. The next few pages are a brief description of the process of harvesting and the physics of geothermal energy.
Geothermal energy is a renewable energy source that has a bright future. While geothermal energy is being used, cost effectiveness geothermal is not great. Geothermal energy is being researched for a more wide use as the cost of fossil fuels rise.
To get started, here is page one.
