Sierra Club: AI power demand could raise US power-sector emissions 42% in five years
A Sierra Club analysis projects that fossil-fuel infrastructure built to meet data center electricity demand could push US power-sector carbon dioxide emissions 42% above 2025 levels by 2030, largely erasing 15 years of emissions reductions. The eventual increase depends on how many planned data centers are built and which energy sources supply them.
What to know
- 01
The analysis projects that completing all planned US AI computing projects would increase carbon dioxide emissions from electricity generation by 618 million tonnes by the end of 2030.
- 02
An earlier study estimated that electricity demand growth from data centers and crypto mining could raise US power-sector emissions by up to 28% compared with a scenario without new data centers.
Why it matters
The analysis connects data center energy choices with US power-sector emissions reductions, but its projections remain dependent on which projects are actually built.
