AI’s Carbon Footprint: A Problem We Can Solve
▼ Summary
– The data center boom is projected to cause a 60-80% increase in US electricity demand by 2050, driving up both carbon emissions and electricity costs.
– Without policy changes, data centers alone could increase US power plant CO2 emissions by 19-29% over the next decade.
– Reinstating tax credits for wind and solar could cut those emissions by over 30% and reduce wholesale electricity costs by about 4% by 2050.
– Current energy demand projections are uncertain due to inflated utility requests and potential future efficiency gains, but data centers were a key driver of last year’s rise in power sector emissions.
– Aggressive policy rollbacks under the Trump administration, including stalled renewable projects, likely mean the analysis underestimates potential future emissions increases.
The rapid expansion of data centers, fueled by the artificial intelligence boom, is projected to significantly increase U.S. electricity demand and carbon emissions. A new analysis warns that without policy changes, this growth could drive up both power sector emissions and consumer costs. However, strategic interventions could mitigate these environmental and economic impacts.
The United States is poised to see a 60 to 80 percent increase in electricity demand through 2050, with data centers alone accounting for more than half of that increase by 2030. If current policies remain unchanged, carbon dioxide emissions from power plants linked to data center energy needs could jump by 19 to 29 percent over the next decade. Power plants are already the nation’s second-largest source of greenhouse gases, contributing roughly a quarter of total emissions. A recent increase in power sector emissions, the first in years, was primarily driven by commercial buildings like data centers.
Forecasting future energy needs for AI is complex. Public estimates often come from utilities fielding multiple requests from data center companies shopping for the best rates, which can inflate the apparent demand. Technological improvements may also enhance efficiency, making some dramatic projections overstated. To create a realistic model, analysts used moderate growth scenarios and assumed only half of all publicly announced projects would actually be built.
The analysis identifies clear solutions: reinstating tax credits for wind and solar power would cut CO2 emissions by over 30 percent in the next ten years, even with rising data center demand. This policy could also reduce wholesale electricity costs by about 4 percent by 2050, following a minor near-term increase. These credits were previously targeted for elimination.
Recent political shifts, however, threaten to worsen the outlook. Aggressive moves against renewable energy and climate regulations over the past year mean the analysis might actually underestimate potential emission increases. While the modeling considered some policy reversals, like rolling back coal plant rules and eliminating renewable tax credits, it didn’t account for others. For example, a new Interior Department policy requiring reviews for all wind and solar projects on federal lands has created a massive bottleneck, stalling projects capable of powering millions of homes. The administration has also issued stop-work orders for several offshore wind farms, though courts have recently allowed construction to resume.
The path forward hinges on policy choices. Embracing supportive measures for clean energy can harness the AI boom without locking in higher emissions and electricity prices for decades to come.
