Some more "by 2080" stuff, albeit less cheery.
For much of my adult life, quite possibly all of it - and I'm not young - I've been hearing this "by 2000" or "by 2020" or "by 2030" or "by 2050" happy talk, usually with a superoptimistic "100% renewable" stuff.
As of 2017, or "by 2017" the entire wind and solar portion of so called "renewable energy" amounted to less than 2% of world energy demand.

The result is that we are seeing concentrations of the dangerous fossil fuel waste CO2 in the atmosphere is approaching 412 ppm, with no end in sight.
Here's a somewhat more dire prediction, a "by 2080" prediction of what the betting of the atmosphere on so called "renewable energy" will produce if it continues as it has for the last half a century of wild cheering for it, first in theory and then, regrettably, in practice:
Nearly one billion people could face their first exposure to a host of mosquito-borne diseases by 2080

I trust you're having a pleasant evening.
