A nuclear generating station emits no greenhouse gases. That’s right, zero. Electricity from nuclear reactors is just as clean as electricity from hydro, wind and solar. It’s much cleaner than electricity from coal, oil and gas.
All energy sources produce greenhouse gases somewhere. Usually it happens during construction, like the concrete used for hydro dams and nuclear generating stations. But greenhouse gases also come from generating stations that burn fossil fuels – coal, oil, and natural gas.
When you compare greenhouse gases on a “life-cycle” basis – which includes the construction, operation and decommissioning of a generating station – nuclear beats coal, gas and solar.
Nuclear-generated electricity is always available night and day. It’s more reliable than wind and solar power, and more affordable than power from any other source but hydro and coal. (And who wants to burn coal?)
