How to Build an Affordable Energy Future
NRDC will develop and release a series of papers called the Build Clean Agenda focused on three areas of reform to speed clean energy and infrastructure deployment.
- Main action: NRDC will publish a multi-paper Build Clean Agenda to modernize laws and permitting, level the playing field for clean energy, and design projects that benefit communities; it calls for U.S. renewable energy production to roughly quadruple, and for at least tripling grid capacity over the next 25 years, and highlights the Western Solar Plan identifying 31 million acres for siting solar on public lands.
- Background and specifics: The piece documents concrete barriers and numbers: the oil, gas, and coal industries receive $34 billion in annual federal subsidies; a 2025 partisan tax bill risks an estimated half a trillion dollars of private clean-energy investment and may raise consumer fuel/energy costs $78–$192 per year; it cites projects like the Grain Belt Express facing multi-year delays and supports targeted reforms such as expanding the “One Federal Decision” approach and giving a federal lead (e.g., FERC) authority to coordinate interstate transmission permitting where uniform standards are met.
