An energy rule of thumb is one third of energy goes to buildings, one third goes to industry, one third goes to transportation. The technology is certainly available to reduce the energy that goes to buildings drastically, nearly to zero even in retrofitting existing ones. If we got serious about it, we could do quite a lot to reduce that third of all energy that goes to heat, cool, and power buildings.
Unfortunately, it seems even with a carbon war going on in the Ukraine affecting the world, we didn’t focus on this readily available tactic which means there will be a lot of unnecessary suffering this winter and, probably, winters to come.
According to this carbon countdown clock (https://www.mcc-berlin.net/fileadmin/data/clock/carbon_clock.htm), at the current rate, the most CO2 we can emit to stay below 1.5ºC rise is 400 Gt, starting from 2020, and that carbon budget will be used up by about July/August 2029.
We have 284 Gts left as I write.
