AI’s arrival complicates Big Tech climate goals, and some worry it’s locking in more fossil fuels

The escalating demand for artificial intelligence is creating significant hurdles for major technology companies in meeting their commitments to reduce greenhouse gas emissions. While companies like Google and Microsoft initially set ambitious 2030 targets for clean energy operations and carbon removal, they now acknowledge these goals are proving challenging due to the immense power requirements of sprawling data centers. Analysts from Wood Mackenzie observe that tech companies are increasingly turning to natural gas to maintain competitiveness, a move that contributes to planet-warming greenhouse gases. Despite substantial investments in clean energy, sustainability reports indicate a notable increase in total emissions for Google (nearly 50%), Amazon (33%), Microsoft (over 23%), and Meta (over 60%) in recent years. Data centers consumed an estimated 4.6% of total U.S. electricity in 2024, a share projected to nearly triple by 2028, potentially driving a 20% increase in nationwide electricity use within a decade. This surge, coupled with power grid connection backlogs and the Trump administration's policies disfavoring renewable energy, is creating a "real near-term crunch on the system," according to Julie McNamara of the Union of Concerned Scientists. Utilities nationwide are planning new natural gas plants to supply data centers, with some tech companies even developing on-site gas plants. Examples include Microsoft's data center in Wisconsin, which will be powered by two new natural gas plants (offset by solar investments), and Meta's large data center in rural Louisiana, which will utilize three natural gas plants. Google plans to procure electricity from a natural gas plant in Decatur, Illinois, with carbon capture. While Microsoft President Brad Smith remains confident in achieving 2030 carbon removal goals through diverse clean energy investments, proposed changes to greenhouse gas reporting could complicate the use of power purchase agreements and renewable energy certificates. Experts like Lori Bird of the World Resources Institute describe the situation as a "mad rush and a lot of competition for resources," with AI partly blamed for a recent uptick in U.S. fossil fuel emissions, raising concerns about delaying the overall transition to clean energy.
