How Much Energy Will New Semiconductor Factories Burn Through in the US?
New semiconductor factories being built in the US by four of the biggest manufacturers -- Intel, TSMC, Samsung, and Micron -- could use more than twice as much electricity as the city of Seattle once they're operational. These companies claim to run on renewable energy, but according to an analysis by nonprofit Stand.earth, that's not entirely true. Semiconductors happen to make up a big chunk of a device's carbon footprint. And unless companies turn to clean energy, they could wind up driving up greenhouse gas emissions as domestic chip manufacturing makes a comeback.
The CHIPS and Science Act, which passed in 2022, set aside $52.7 billion in funding for domestic chip manufacturing. Now, the four companies scrutinized in the report have plans to build megafactories in Arizona, Ohio, Oregon, Idaho, Texas, and New York. Each of those megafactories alone could use as much electricity as a medium-sized town, according to the report. Cumulatively, nine facilities could eventually add 2.1 gigawatts in new electricity demand. "We're not slowing down on any of our sustainability commitments, even with our recently announced investments," Intel said in an email.
