CO2 emissions are in kg/kWh; nuclear waste relates to high-level waste in g/kWh.
* The weighted aggregate for nuclear power’s share of fuel mix is only about two-thirds of the UK “average” figure. This is probably because nuclear power is being supplied disproportionately to industry rather than domestic customers, partly because of nuclear’s proportionately higher night-time output due to its inability to load follow (adjust its output with varying demand). Aggregated coal and gas figures are both slightly higher than the average figures.
Coal power plants also emit sulphur dioxide which leads to acid rain, as well as other pollutants.
Note that the figures for carbon dioxide emissions are for emissions directly related to electricity generation and take no account of lifecycle emisions.
For nuclear power in particular there are carbon dioxide emissions related to construction and the mining and processing of the uranium fuel.
The nuclear waste figure does not include intermediate and low-level nuclear waste. Though less radioactive, these lower level wastes are created in much larger volumes, are still dangerous, and represent a disposal problem.
