- New gas projects for US data centers, linked to AI companies like OpenAI and Microsoft, could emit over 129 million tons of greenhouse gases annually, exceeding Morocco's 2024 emissions.
- Behind-the-meter power, where data centers bypass the grid with dedicated gas plants, is rising due to grid constraints and public resistance to higher energy bills.
- Examples include xAI's turbines in Memphis and Southaven, potentially emitting 6.4 million tons of CO2 each per year, and Microsoft's Chevron-backed Texas project, with over 11.5 million tons annually.
- Permitted emissions are theoretical maximums; actual emissions may be lower, but estimates suggest even half could surpass Norway's 2024 emissions, equivalent to over 153 average gas plants.
- Data centers' constant power demand may lead emissions to approach permit levels, unlike grid plants that adjust to demand, and turbine shortages might force use of less efficient models.
- Large projects like Stargate (potential 24 million tons/year) and Fermi's Trump Campus (over 40.3 million tons/year) highlight massive carbon footprints, with Fermi emphasizing 'clean' natural gas as a bridge to nuclear.
- Tech companies' carbon reduction goals are challenged; e.g., Meta's Ohio projects could offset 10% of its recent emissions cuts, despite pledges and investments in carbon capture.
- Behind-the-meter gas for data centers surged from 4 gigawatts in early 2024 to nearly 100 gigawatts by early 2026, with recent pledges and political inquiries underscoring rapid growth.
- Not all permitted projects will be built due to factors like lack of clients, turbine shortages, or strategic shifts, but the trend raises climate concerns about long-term fossil fuel reliance.
