Solar, wind and nuclear are already causing closing of many coal plants.
Energy usage has plateaued in the west and everybody’s CO2 intensity is going down, see previous post and any news about China.
AI is increasing energy usage but there’s a solution to that: Let’s put data centers in space when scale gets large.
(Then when the amount grows further orders of magnitude, use materials from asteroids and Mercury.)
Recent positive news
Let’s use this new “1,5,7-triazabicyclo [4.3.0] non-6-ene” aka “TBN” material to capture carbon dioxide: press release
Let’s frack some peridotite and have it absorb the CO2: paper
What to watch out for
Gas turbines for AI data centers. If AI training data centers are built near cheap gas sources, and large amounts of turbines are built for them, then that has potential to wreck the climate seriously, either with CO2 emissions or even worse, with methane slip.
