According to Calvert, "Alternative Energy generally includes renewable energy sources such as solar, wind, geothermal, biofuel, hydrogen and biomass. Also included in the Alternative Energy category are the technologies that make renewable energy sources practicable, as well as services and technologies that promote the conservation or more efficient use of conventional energy sources*."
Jim Graham says that Uranium, The "Clean, Safe, Cost Effective Energy Source" is, "Nuclear energy has distinct environmental advantages over fossil fuels, in that virtually all its wastes are contained and managed - nuclear power stations do not cause any pollution. The fuel for nuclear power, uranium, is virtually unlimited, considering both geological and technological aspects. That is to say, there is plenty of uranium in the earth's crust. The safety record of nuclear energy is better than for any major industrial technology."
