- Wetlands Land that contains water for all or part of the year. Characteristics: Distinct soils Varied species: insects, water plants, and amphibians, etc.
- Slide 58
- Wetlands, continued Why are they important? Reduce erosion and runoff Cycle nutrients Reduce pollutants Create recreational areas Habitats to many different species Breeding & spawning grounds Nursery and food factories

- hydroelectric Advantages: -renewable -little pollution -controllable and constant -not expensive once built Disadvantages -cant be used everywhere -initially expensive -floods the river and blocks transportation -harms ecosystems-fish ladders
- Slide 60
- Geothermal Advantages: -renewable -little pollution -controllable and constant -not expensive once installed Disadvantages -cant be used everywhere -initially expensive -difficult to install after house is built -Steam can contain minerals and chemicals.
- Slide 61
- Solar energy Advantages: -renewable -little pollution -not expensive once installed -abundant Disadvantages -not constant -initially expensive -PV cells made of toxic chemicals -harms ecosystems-birds and insects
- Slide 62
- Wind energy Advantages: -renewable -no pollution -not expensive once installed Disadvantages -not constant or controllable -initially expensive -noisy and eyesore -harms ecosystems-birds
- Slide 63
- Biomass Advantages: -renewable -less pollution -reduces trash -fuel made in US -constant and controllable Disadvantages -gives off CO2 -lack of infrastructure-gas pump -raised food prices -ashes are hazardous
