What is Geothermal energy

Geothermal energy is a form of energy that comes from the earths natural heat

It comes from radioactive decay and sunlight

It is efficient and inexpensive However it is limited to the edges of

the tectonic plates

advantages

The power is constant It is very clean energy The power is renewable New technologies have made it more

accessible to other areas of the world

Disadvantages

Geothermal energy has low heat so unless the exhaust can be directly used the heat left over is wasted

It is limited to areas around the tectonic plate and other geothermal hot spots

Wells drilled release co2 and other pollutants.

How do the plants work

Dry Steam Plants- these plants use geothermal steam to power turbines.

Flash Steam Plants- use pressurized water to flash into steam and turn turbines

Binary Cycle Plants- these are the newest plants that use a liquid with a boiling point lower than water and different pressures to flash steam and turn turbines

Heat uses

Most of geothermal heat is used in space heating.

A third of the energy is used for heating pools

The leftovers are used for agricultural uses
