Executive Summary

The U.S. federal government repealed the legal foundation for greenhouse gas regulations, prompting immediate lawsuits from 13 states. Meanwhile, tech giants are investing in high-temperature superconductors and on-site microgrids to meet AI power demands that are projected to reach 12% of total U.S. electricity by 2028. Globally, China maintained flat emissions for nearly two years as renewables began outcompeting coal on cost. Key Takeaways: • Microsoft and Veir are using liquid nitrogen-cooled superconductors to deliver power capacity an order of magnitude higher than standard copper lines for AI infrastructure. • The Supreme Court struck down Trump's fentanyl and reciprocal tariffs as illegal under the International Emergency Economic Powers Act, providing cost relief for solar and battery stocks. • Standard data center metrics (PUE) miss 70% of total environmental impact, as manufacturing hardware emits twice the carbon of data center operations.

Key Themes

Major trends and developments identified from this week's coverage

Data Center Power Infrastructure

Microsoft and Amazon are testing high-temperature superconductors and microgrid software to deliver massive electrical loads to AI hubs while bypassing grid transmission bottlenecks.

US Climate Policy Reversal

The Trump administration revoked the 2009 'endangerment finding,' removing the federal obligation to regulate vehicle and industrial emissions under the Clean Air Act.

China's Energy Structural Shift

China's CO2 emissions remained flat or fell for 21 months as cheaper renewable energy eroded the business viability of coal power plants.
