Story summary

The Union of Concerned Scientists warns electricity demand could rise 60–80% by 2050 due to data centers.
If policies stay unchanged, power-plant CO2 emissions could grow 19–29% over the next decade.
Reinstating wind and solar tax credits could reduce emissions by over 30% and lower electricity costs by about 4% by 2050.
However, U.S. President Donald Trump’s actions against renewable energy may lead to underestimated data-center emissions.
