: 1. Cold water is pumped deep underground.
: 2. Water is heated as it passes through rocks underground.
: 3. Water turns to steam and passes down pipes to turn a turbine.
: 4. The turbine causes a generator to spin.
: 5. The generator makes an electrical current.
====Advantages====
*Extremely reliable (does not depend on sunlight or wind).
*Can be used to generate electrical power or to heat buildings directly.
*Does not cause pollution or significant environmental damage.
*No fuel cost.
====Disadvantages====
*Expensive to build when compared to how much money can be made selling the power.
*Can only be built in volcanic areas.
