Guest Lecture 2 Mini-Quiz

What is geothermal energy?

• energy generated and stored in the earth that continuously flows outward from deep within the earth

• radiant light and heat from the Sun that is harnessed using solar heating, photovoltaics, or solar thermal energy

• plant or animal material used as fuel to produce electricity or heat

• the use of falling or fast-running water to produce electricity or to power machines

How do geothermal power plants work?

• Cold water is heated up and the water power turbines under the water and turns it into electricity

• The hot water from inside the earth meets cold air and produces condensation which powers the turbines and turns it into electricity

• Cold water is pumped down, meets the hot water from inside the earth to produce steam, goes back up to power turbines, creating electricity

• Cold water from the river meets hot rocks near the surface of volcano creating steam to generate heat
