One of the tragedies to me: nuclear and renewable power could absolutely fulfill and surpass our current energy needs. Pick a per annum growth rate of energy production and go.
At some point power becomes so cheap and plentiful that battery size and tech is essentially solved. Industry eventually gets converted to use electricity as the price would drive emissive processes out. And generally allows the economy to produce and do more.
Like at some point you can live essentially anywhere and thus leave the precious wild places undisturbed. Want water in the desert? Build an aqueduct in and do desalination. Similar for places that are too cold/hot/etc to be habitable or productive.
