1. Review Energy Types

2. Energy Types From Atmosphere: From Lithosphere: From Hydrosphere:
Solar
Wind
From Lithosphere:
Fossil fuels
Nuclear
Geothermal
From Hydrosphere:
Hydroelectric
Tidal and ocean currents

3. Non-Renewable Resources
Geothermal Energy → Derived from lithosphere
Fossil Fuels → Derived from lithosphere
Hydroelectric Energy → Derived from hydrosphere
Nuclear Energy → Derived from lithosphere
Tidal Energy → Derived from hydrosphere
Solar Energy → Derived from atmosphere
Wind Energy → Derived from atmosphere

4. Non-Renewable Resources
1. Burning of Fossil Fuels (coal, natural gas, oil)
- Carbon based substances burned to produce heat
- boils water
- Boiling water turns turbine
- Turning turbine produces electricity
Cons: Produces GHGs and other pollutants
Energy Transformation:
Chemical → Thermal → Kinetic → Electric

5. Non-Renewable Resources
2. Nuclear Energy
- Splitting of atom to release huge amount of energy,
- boils water
- Boiling water turns turbine
- Turning turbine produces electricity
Cons: Nuclear waste is radioactive, risk of accidents
Pros: no GHGs or pollutants, lots of energy!
Energy Transformation:
Nuclear → Thermal → Kinetic → Electric

6. Renewable Resources 1. Geothermal Energy
- Use Earth’s internal heat to boil water
- Boiling water turns turbine
- Turning turbine produces electricity
Cons: Can’t use everywhere, expensive to install, may contaminate water
Pro: no GHGs
Energy Transformation:
Thermal → Kinetic → Electric

7. Renewable Resources
2. Hydroelectric Energy - Use movement of water to turn turbine - Turning turbine produces electricity Con: Can’t use technology everywhere (need large enough body of water), damages ecosystem Pro: no GHGs Energy Transformation: Kinetic → Electric

8. Renewable Resources
3. Tidal Energy/ocean currents - Use movement of underwater currents to turn turbine - Turning turbine produces electricity Cons: Can’t use technology everywhere (need large enough tidal range), expensive to install, damage to marine life a possibility Pro: no GHGs or pollutants Energy Transformation: Kinetic → Electric

9. Renewable Resources
4. Solar Energy - Photon hits photovoltaic cell, causes electrons to move - Moving electrons = electricity Cons: Sun not always consistent, expensive Pro: no GHGs Energy Transformation: Radiation → Electric

10. Renewable Resources Kinetic → Electric 5. Wind Energy
- Use movement of wind to produce electricity
- Wind causes turbine to turn
- Turning turbine produces electricity
Cons: Wind not always consistent, can’t store, considered ugly, noisy
Pro: no GHGs or pollutants
Energy Transformation:
Kinetic → Electric

11. Example Questions- Energy Resources
A community in Gaspé is researching the environmental impact of two different energy technologies: a tidal power plant and a coal power plant. For each of the energy resources the community is considering, state: • the energy source as renewable or non-renewable • the main environmental impact for each type of energy
