Renewable Energy Advantages and Disadvantages

Alligators in Idaho

Tectonic Plates

Geothermal Energy

Tectonic Plates

Reykjavik, Iceland

Geothermal Energy Disadvantages: Only possible in “hot spots”

Geothermal Energy Advantages: Little release of carbon dioxide No release of nitrogen or sulfur oxides No smog renewable

Hydropower Advantages: No release of carbon dioxide No release of nitrogen or sulfur oxides Renewable

Hydropower Disadvantages: Disrupts ecosystem Young fish swimming downstream get chopped up in turbine Spawning fish blocked from spawning ground upstream

Wind power Advantages: No nitrogen oxides or sulfur oxides No carbon dioxide released No smog renewable

Wind power Disadvantages: Danger to migratory birds Ruins “view shed” Noisy May hurt property values

Biomass Advantages: Both a source and “sink” of carbon dioxide Renewable energy

Biomass Disadvantages: Time and land required to grow crops- $ Not as much thermal energy released per unit mass as fossil fuels

Solar Power Advantages: Renewable No release of carbon dioxide No release of sulfur or nitrogen oxides No smog

Solar Power Disadvantages: PV cells are expensive PV cells are inefficient in generating electricity
