With climate change looming, it seems so completely backwards to go back to using it again.
Is it coal miners pushing to keep their jobs? Fear of nuclear power? Is purely politically motivated, or are there genuinely people who believe coal is clean?
Edit, I will admit I was ignorant to the usage of coal nowadays.
Now I’m more depressed than when I posted this
Right it would be something involving number of people harmed, for number of joules or watt-hours of energy produced. How much injury, death, etc is there on a per-unit basis. That would be how you’d get a probability of harm. Then you could compare it numerically with other forms of energy to see which is the safest, statistically speaking.
