GeOTHERMAL ENERGY

GEOTHERMAL

• Renewable Energy
• Geothermal energy is collected from deep in the earth
• Pipes are used to collect energy
• It is used in mostly in the Western United States
• US has 77 geothermal plants

Geothermal Pipes

HOW IS GEOTHERMAL ENERGY CONVERTED TO ELECTRICITY?

• Uses pipes buried more than 4 feet deep in the earth
• Liquid is pumped through pipes
• Heat is absorbed and brought indoors
• Then reverse to cool. Heat exchanged takes heat from inside house
• Moves heat back into ground

GEOTHERMAL ADVANTAGES

• Does not produce greenhouse gases
• Energy source is free and comes from the earth
• Power stations are smaller than other power plants
• Energy does not run out
• No outside fuel source is needed to keep the power plants running

GEOTHERMAL DISADVANTAGES

• There are not many places where we can build geothermal power stations
• Most plants need to be built near the west where there is volcanic activity
• Harmful gases and minerals may occasionally come up from ground below
• Gases can sometimes be hard to control
• Building geothermal power is expensive to build

CAMPAIGN SLOGAN

• Green Energy is clean energy
• Don't be mean , go green!!

WHY SHOULD WE SWITCH TO AN ALTERNATIVE ENERGY SOURCE.

• Fossil fuels are running out
• Combustion of fossil fuels releases greenhouse gas
• Greenhouse gases are to blame for increased temperatures, melting of glaciers and dying of coral reefs
• Fossil fuels cause air pollution
• Reduces our dependence on oil
