Electricity The ________ Act requires industries to reduce or eliminate the release of point source pollution into surface waters. Clean H2O The nations most important air pollution law is the _______ Act. Clean Air The element ________ is used in nuclear fission to produce energy. Uranium Explain the difference between renewable and nonrenewable resources. Renewable: Can be made in yearsNonrenewable: Can be made in millions of years Beginning with plant material, list the successive stages of coal development. Peat ; lignite ; sub-bituminous ; anthracite List two of the advantages of solar energy. saves you money, low/no maintenance List the advantafes and disadvantages of wind as a source of electricity. it saves energy but creates noise pollution Contrast point source pollution and nonpoint source pollution. point source you can find where it is, nonpoint you cant How could energy conservation help to control or decrease air, water, and land pollution? most of our energy comes from burning fossil fuels, burning fossil fuels pollutes the air by putting all soot of noxious gases in it as well as greenhouse gases which affect the climate.
