Net energy It takes energy to get energy • The total amount of energy available from resource minus the energy needed to find, extract, process, and get that energy to consumers
Types of Energy Resources • Conventional Oil • Oil sands/Shales • Natural gas- found above oil deposits, propane-vs-natural gas • Coal • Synthetic fuels (turning coal into a liquid or gas) • Nuclear fuel
Rank them in terms of how much it costs to mine, process and create electricity/fuel
Cost of production • Conventional Oil: low cost • Oil sands/Shales: moderate cost • Natural gas: low cost • Coal: low cost • Synthetic fuels: moderate cost • Nuclear fuel: high cost
Size of potential supplies • Conventional Oil: Ample supply for near future • Oil sands/Shales: Ample supplies • Natural gas: Ample supply • Coal: Ample supplies • Synthetic fuels: Large potential supply • Nuclear fuel: Ample supply
Rank in terms of pollution Air, Carbon dioxide
Air pollution • Conventional Oil: A lot of pollution • Oil sands/Shales: A lot of pollution • Natural gas: Less than Coal, Oil • Coal: Severe Air pollution • Synthetic fuels: Lower than Coal • Nuclear fuel: Least amount of air pollution
Amount of CO2 emissions • Conventional Oil: high emissions • Oil sands/Shale: high emissions • Natural gas: lower emissions than coal, oil • Coal: high emissions • Synthetic fuels: higher emissions than coal • Nuclear fuel: Low emissions
Water pollution • Conventional Oil: cause of water pollution • Oil sands/Shales: Severe water pollution • Natural gas: pollution in extraction process • Coal: Severe water pollution • Synthetic fuels: High water use, some pollution • Nuclear fuel: High water use, some pollution
Rank in terms of pollution Land/Wildlife disruption
Land/wildlife destruction • Conventional Oil: Low land use • Oil sands/Shales: Severe land disruption • Natural gas: Low land use • Coal: Severe land disruption • Synthetic fuels: High environment impact • Nuclear fuel: Moderate land use
Amount of government subsidies • Ease of transportation • Are environmental costs factored into price? • Who owns the resource reserves?
