That’s 2.5 doublings in 23 years, or a bit better than one doubling per decade. Growth was still high after that, but doubling slowed a bit (we were running into limitations of gas and especially oil availability… we kind of stopped using oil for electricity after the 70s). Point being we absolutely can scale, particularly if we’re scaling something that is not as inherently limited as oil is. Solar in particular can scale out massively (as could nuclear if we got our act together).
