Rep. Westerman released changes to the SPEED Act. The new version would still establish a framework designed to expedite projects regardless of environmental consequences. There are better ways to reform the permitting process.

We need more effective planning processes to ensure grid reliability. @fernandez.house.gov introduced the Integrated Resource Planning Modernization Act, which I helped draft during my AAAS Fellowship.

The federal retreat on hydrogen is frustrating, but it must not be the end of the story. States acting decisively now could position themselves as leaders in the hydrogen economy climate science tells us we desperately need.

Data centers could increase US electricity costs by 8% and emissions by 30% by 2030. These trends create fundamental challenges for grid planning. Solutions exist, but policymakers must act now. Read more at Amped Up!

Two actually good permitting bills heading to House committee: ePermit Act (digital tools + coordination) and NEPA Data Act (empirical analysis of review timelines).
