ENERGY SOURCES LOCATION ENVIRONMENTAL IMPACT Biomass • anywhere land, water and sun are available (in competition with wildlife and people) • requires transportation to use point • burning produces air contaminants (especially carbon dioxide) • no net production of carbon dioxide (amount released during energy production is equal to amount absorbed during plant growth) • fire hazard at storage sites with resulting loss of property and air pollution Water (tidal .river) • discrete locations, often far away from population areas • may require distribution • very clean, no effect on atmosphere • damming or diverting rivers and interfering with tidal flow may alter or destroy ecosystems • risk of collapse of dams resulting in loss of life (human, livestock, wildlife) and property Geothermal • easily accessible at discrete locations, often far away from population areas • may require distribution • very clean, minor effect on atmosphere (release of sulfur?) Wind • discrete locations, often far away from population areas • may require distribution • very clean, no effect on atmosphere • local noise • unsightly (“eyesore”)
