2. Solutions:We have the answers! Energy Efficiency! (Miller Ch. 17) 43% of energy in the US is wasted unnecessarily Incandescent bulb=5% efficient Fluorescent bulb=20% efficient Auto fleet standards = CAFE Standards (Corporate Average Fuel Economy) 12.9 mpg in 1974 27.9 mpg today 40 mpg CAFE standard would cut gas use by 50% What is nuclear energy? In a nuclear fission reaction, neutrons split the nuclei of atoms such as uranium-235 and plutonium-239. In the process, energy (primarily in the form of high temperature heat) is released. In a nuclear reactor, the production of heat generated by this reaction is controlled and used to produce high pressure steam, which is in turn used to spin turbines that generate electricity. Nuclear fission is basically the splitting of nuclei of certain isotopes with large mass numbers. Neutrons are fired at them, which causes them to split into lighter nuclei and to release single neutrons and energy. These single neutrons can in turn cause additional fission, but there has be enough single neutrons (critical mass) in order for the reaction to sustain itself. If controllable, nuclear power can be an efficient source of power, but large government subsidies distort the true price of nuclear and the disposal of nuclear waste has proven to be an environmentalists nightmare. Disasters on the global scale, such as Chernobyl and Three Mile Island, also highlight the risk of this type of energy source.What is nuclear energy?
