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?

7. Impacts of hydropower on Species and People_______________ Dams can provide many human benefits but:
Disrupts ecological services rivers provide; e.g. 119 dams on Columbia River have caused a 94% drop in wild salmon; removing hydroelectric dams will restore native spawning grounds
Displaces millions of people worldwide as reservoirs flood traditional homelands
No room for expansion in the US
