> The report finds that data centers consumed about 4.4% of total U.S. electricity in 2023 and are expected to consume approximately 6.7 to 12% of total U.S. electricity by 2028.
Even if data centers went 10x, that would only increase our electricity use by a bit over a third.
.
But for something more fun:
This[1] says global energy use is 186,000 TWh/year. Or an average of about 21.2 TW.
The surface area of the earth[2] is 510 million km^2, or 510 trillion m^2.
Which works out to global energy use being an average of about 42 mW / m^2.
Per Wikipedia[3], the IPCC says that human-caused greenhouse warming is 2.72 W/m^2 .
Which is "only" about 65 times global energy use.
Which means if we did start using double-digit multiples of our current energy use, it starts to matter whether we're adding that energy to the environment (fission/fusion, fossil, probably geothermal) or just redirecting it (hydro, wind, solar). With the caveat for solar that the panels probably have lower albedo than what they're on top of.
