Geothermal energy is the heat from the Earth

It is clean and sustainable

Page 3: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Reduce the amount of fossil fuels being used

The creation of new jobs

Page 4: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

No pollution Cheaper than fossil fuels

Page 5: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Expensive installation costs

Only available in some regions

Page 6: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Harmful gases could be released

Transportation of geothermal energy is difficult.

Page 7: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Shallow ground Hot water and hot rock found a few

kilometers beneath the surface of the Earth Extremely hot temperatures of molten rock

called magma

Page 8: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

The average temperature of the upper 10 feet of the Earth’s surface ranges from 10° to 16° Celsius.

Page 9: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Wells can be drilled into hot water and rocks a few kilometers below the Earth’s surface.

Page 10: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Magma may come close to the surface, if this magma heats a water source, useable geothermal energy is created.

Worldwide use

Page 12: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Geothermal Energy can be found almost anywhere in Canada for direct use of heat.

Geothermal energy for electricity generation can be found in B.C, North Western Canada, and the Prairies.

Page 13: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Due to the Canadian shield, Ontario is a hard place to create electricity through geothermal power plants.

It is possible to use large bodies of water and the heat from the ground to use to heat and cool buildings

Page 14: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Geothermal energy from steam and hot water reservoirs is most common.

Converting geothermal energy directly to heat.

Page 15: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Cold water circulates through hot rock and heats up.

The hot water powers a turbine which powers a generator.

Page 16: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Power plants for geothermal energy are expensive due to new technology and deep wells that are required.

Lower cost of long periods of time.

Page 17: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

There are three main ways to generate geothermal electricity.

The three different power plants are Dry steam Plant, Flash steam Plant, and Binary Plant

Page 18: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Dry steam power plants use underground resources of steam that are pumped up into the turbine to generate electricity.

Page 19: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Flash steam power plants use underground resources of hot water that are above the temperature of 182 Celsius. This water is then

turned into steam to power a turbine.

Page 20: Braden and Matthew.  Geothermal energy is the heat from the Earth  It is clean and sustainable

Binary cycle power plants operate with water between 107-182 Celsius. This water is used to boil a second liquid to power the turbine to create electricity.

In 2009,geothermal Energy was 5% of the total amount of renewable energy used by the US
