Energy safety looks different when deaths are counted per unit of electricity

Spectacular accidents dominate memories of energy risk. Air pollution is more diffuse, but excluding it makes fossil-fuel generation appear safer than a fuller health accounting suggests.

This explainer compares deaths from pollution and accidents per unit of electricity, rather than comparing raw totals from energy sources used at very different scales. It also places those estimates alongside greenhouse-gas emissions.

The resulting contrast strongly favors nuclear power and modern renewables over fossil fuels on these measures. That does not resolve every grid-design question, from cost and construction time to reliability and waste. It establishes a better denominator for one part of the debate. An energy source can have visible hazards and still compare favorably with an incumbent whose damage arrives continuously and less conspicuously.
