57. Wetlands Land that contains water for all or part of the year. Characteristics: – Distinct soils – Varied species: insects, water plants, and amphibians, etc.

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

59. 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

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.

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

62. Wind energy Advantages: -renewable -no pollution -not expensive once installed Disadvantages -not constant or controllable -initially expensive -noisy and eyesore -harms ecosystems-birds

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
