Renewable Energy: Geothermal (Week 11, Lecture 3)

This is the final video in our series on renewable energy sources. In this lecture, I will describe how electricity is generated using geothermal energy, and what environmental constraints are faced by this type of energy generation. I will describe how geothermal energy can be used for space heating, and I will also explain the basic way a geothermal heat pump operates and how it differs from using geothermal energy to generate electricity.
