Few people know this: half of the world's energy use is for heat used in buildings and industry.
And almost all of it is from burning fossil fuels.
That's why we need to decarbonise heat if we want to stand a chance of meeting our climate targets.

(For some reason I think the other one just reflected Chicago. Although it does say global!)
Quick picks:
1. Investment in better architecture & been buildings important.
2. Ppl pick on aviation as a big contributor, but negligible wrt Road Transport
3. Energy use in Industry, especially Other, needs attention.
Do you have a link for the source report for this graphic?

I’m sure everything has changed massively since this was put together in 2016.
I was using it as an example of how much human activity has yet to be decarbonised.
It’s a lot!
I saw it was a tad outdated, but I'm guessing that the overall distribution might still be representative enough.
Yep, you're right. Still a lot to do.

Also important is training programs for existing facilities management staff. These staff are the ones who, when they aren't trained in technology like Geothermal, stand in the way of those changes (they don't want to lose their jobs)
It runs on 12g of Uranium 237 and lasts for decades.
The data about air conditioning in 2050 is widely available

A/C, on the other hand, runs here at least nine months of the year. As heat waves are spreading to upper latitudes, we must decarbonize the GRID even more.
Heat pumps, driven by non-fossil-generated electricity.
Also the lowest footprint on all metrics.
Electric heat is still using fossil fuels. Is there anything I can do now?
This can erase 90% of your residential carbon footprint today. As more renewables come online, you get the other 10%.
Hoodies aren't just for tech nerds and goth chicks and toques aren't just for Canadian hockey fans. Bundle up, turn the thermostat down.
Wind, depends upon the turbine, but it's 2-40 acres per MW.
Solar PV is 5-7 acre's.
All of that land could be used for food, housing or conservation.
What if an ocean based tech did the same but in 12 square metres....
Not exactly practical.
Some home's and buildings can be retrofitted, the vast cannot.
Solar and wind do provide a solution, however, they also create more problems than they solve....
