It depends on how you define it. How about mortality per kWh?
But coal is literally the most deadly source of energy in use, yet we happily use it, and extend its usage for decades to come.
Don't we care about all the people killed by burning coal? Or 60'000 killed by a dam disaster in China in 1976?
Of course we do, but we also need 24/7 energy so we make compromises 🤷
