The US Senate has unveiled a bold plan to rein in carbon emissions from cryptocurrency mining and AI data centers, sparking debates about energy use in the tech sector. The Clean Cloud Act of 2025—spearheaded by Democratic Senators Sheldon Whitehouse and John Fetterman—aims to push mining operations toward renewable energy by 2035 or face escalating penalties.
The Clean Cloud Act: Key Details
• Regional Emission Caps: Facilities using over 100 kW of energy must meet location-specific carbon limits, based on the Department of Energy’s National Transmission Needs Study.
• 11% Annual Reductions: Caps tighten yearly until reaching zero emissions by 2035, effectively mandating 100% renewable energy use.
• Fines for Non-Compliance: Starting at $20 per ton of CO₂ for excess emissions, penalties rise annually with inflation + an extra $10. Funds will subsidize residential energy bills and clean energy projects.
• Transparency Rules: Mining operators must submit detailed reports on energy sources and usage, with fines applied to tenants rather than landlords.
Why Crypto Miners Are in the Crosshairs
Bitcoin mining’s energy-intensive proof-of-work model has drawn scrutiny as US data centers—including those for AI—are projected to consume 12% of national electricity by 2028 1 2. The bill’s supporters argue unchecked growth threatens climate goals and could spike household energy costs.
Industry Pushback:
• Matthew Sigel, VanEck’s research head, criticized the proposal as a “blame-the-server-racks” strategy, calling it overly simplistic 3 4.
• Major miners like Galaxy, CoreScientific, and Terawulf are already diversifying into AI data hosting to offset declining crypto revenues 5 6.
Political Hurdles and Industry Adaptation
The bill faces stiff opposition from Republicans, particularly under President Trump, who has prioritized making the US a global leader in both AI and crypto. His administration reversed a 2023 Biden-era AI safety order and supports expanding domestic mining 7.
Mining’s Pivot to AI:
• Falling Bitcoin prices and post-halving revenue drops have driven miners to repurpose infrastructure for AI workloads.
• Analysts note this shift stabilized revenues in early 2025, though trade wars and tariffs loom as new risks 2 8.
What’s Next for Crypto Miners?
If passed, the Clean Cloud Act would mark one of the most aggressive climate policies targeting tech infrastructure. While proponents see it as a necessary step toward sustainability, critics warn it could drive mining operations overseas to regions with laxer rules.
For now, the bill remains in draft form, but its progression could redefine how crypto balances growth with environmental accountability. As one Senate Democrat tweeted: “Industries profiting must pay their own way” 7.

Key Stats:
• 12%: Projected US energy demand from data centers by 2028.
• $20/ton: Initial penalty for excess emissions.
• 2035: Deadline for 100% renewable energy use.
