What are the safest and cleanest sources of energy?
Coal causes most harm on both metrics: it has severe health costs in the form of air pollution and accidents, and emits large quantities of greenhouse gas emissions. Oil, then gas, are better than coal, but are still much worse than nuclear and renewables on both counts.
