Nobody is, as far as I know, invading the humans' territory from someplace else, such as Delta Centauri. Humans invading other humans' territory is just a sort of humans fighting among themselves, but not, currently, the sort that is the biggest obstacle to the renewable transition.
Agree. And maybe it will encourage Europe to build out renewables and heat pumps faster.
Apparently it has not had that effect in Romania, yet. But they are by report still happy with their Canadian CANDU reactors.
Invasion is an activity, not an identity. Those so engaged could stop anytime. Many will.
