US Revokes Limits on Power Plants' Climate Pollution
US regulators have rolled back 2024-era limits that would have forced existing coal plants and new gas plants to capture 90% of their CO₂ emissions or shut down by 2039, effectively reverting power-plant climate rules to weaker pre-2024 standards. Commenters argue over whether this is an economic necessity to keep energy cheap and industry competitive, or a reckless move that ignores the falling costs and rapid global deployment of renewables, storage, and nuclear power. The thread also delves into whether CO₂ should be treated as “pollution” under existing legal frameworks, how U.S. backsliding affects global climate efforts relative to China and Europe, and the broader trade-offs between environmental protection, energy security, and political power.
Regulation Rollback & Scope
- 2024 standards required existing coal and new gas plants to capture 90% of CO₂ or close by 2039; estimated reduction ~1.38B tons CO₂ through 2047.
- Rollback returns to pre‑2024 federal CO₂ rules, which commenters say were weak or effectively absent for existing plants.
- Some argue the change is “just” reverting a very new regulation and the headline overstates it; others stress that undoing even modest progress while climate risks mount is significant.
Climate Risk, Morality & Responsibility
- Many express anger and despair, framing this as sacrificing future generations and global stability (“mass migration,” “uninhabitable regions”).
- Others take a more fatalistic view: we are already on track for >3°C warming, and this mainly cancels out progress elsewhere.
- Moral framing recurs: “I got mine” attitudes, relative power of capital over labor, and “cruelty/performance of power” as political strategy.
Economics, Energy Mix & Feasibility
- Pro‑rollback voices: strict climate rules damage US industry, drive offshoring, and ignore that EVs, gas bans, and dam removals strain a grid without reliable baseload.
- Counterarguments:
- Utility‑scale solar/wind (with storage) are claimed to be already cheaper than new fossil; fossil plants remain profitable only because capex is sunk and externalities ignored.
- Wars and price shocks show fossil dependence is a strategic liability; renewables improve energy security.
- Disputes over whether “the math adds up” for renewables: storage scale, intermittency, and cost of batteries vs gas/coal; Germany, Australia, and France cited in conflicting ways.
- Nuclear appears as a recurring “missed opportunity” in some regions (Germany, US, UK).
CO₂ as “Pollution” & Regulatory Authority
- One long subthread debates whether CO₂ fits traditional “air pollution” categories underlying US clean‑air law.
- Critics say CO₂ was shoehorned into a framework designed for scrubbers on localized pollutants, giving EPA de facto power over the entire energy sector.
- Others argue CO₂ has long been understood as harmful atmospheric pollution, and that broad definitions (including noise pollution etc.) are appropriate; EPA should address any large‑scale environmental harm.
US, China, India & Global Fairness
- Some claim US action is pointless while China and India build coal plants; others respond that:
- China is simultaneously adding massive solar, wind, and nuclear, with coal flat or declining in electricity share.
- India’s per‑capita emissions are far below the US, and renewables there are growing quickly.
- Proposed solutions: carbon pricing/dividends plus border carbon tariffs to align incentives rather than mutual inaction.
Politics, Lobbying & Interests
- Many see the rollback as driven by fossil‑fuel interests and short‑term profit for plant owners, not public welfare.
- Coal’s actual employment footprint is noted as small; support for coal is described more as culture‑war nostalgia than economic rationality.
- Some argue US voters knowingly chose this trajectory and that institutional checks (Congress, durable laws) were never built.
Rooftop Solar & Distributed Solutions
- Thread briefly examines why US suburbs aren’t saturated with rooftop solar: high up‑front costs, aging roofs, HOAs, renter–owner misalignment, complex regulation, and relatively cheap grid power in many regions.
- Comparisons to Europe note higher energy prices there make rooftop solar more attractive, and that utility‑scale solar may be more cost‑effective than rooftop in the US.
