There is no one ideal energy source. The best approach is, as always, to diversify. Relying completely on one source is irresponsible. Nuclear with renewables is a fantastic mix. Especially in countries that can’t reliably generate significant amounts of electricity with hydro.

Renewable sources of energy are safer

They’re actually not, generally speaking. All types of renewable energy, with the exception of solar, cause more deaths than nuclear does.

Some articles report slightly lower death tolls for renewables, but don’t provide any sources for that data. Geothermal energy, which neither of the two sources above includes for some reason, sits right next to wind, so slightly above nuclear in terms of deaths caused per terawatt-hour.
