Cold weather and data centres drive up US greenhouse gas emissions

Rhodium Group estimates US greenhouse-gas emissions rose 2.4% in 2025 after a very cold start to the year and surging electricity demand from data centres and cryptocurrency mining. Residential natural gas consumption climbed nearly 7%, coal generation jumped 13% as fuel switching occurred amid higher gas prices (linked to large gas exports), and solar generation expanded 34%; road transport emissions were flat as hybrids grew 25%. The mix signals a short-term coal rebound and structural upward pressure on power demand that could affect utilities, thermal coal and gas markets, and renewable deployment trajectories.

Analysis

Market structure: The immediate winners are coal producers and merchant power generators exposed to thermal coal (coal generation +13% y/y) and large natural-gas-exporting producers that keep Henry Hub elevated; losers are gas-fired baseload generators and consumers facing higher retail power/heating bills (residential heating fuel use +7%). Rapid data‑centre and crypto load growth shifts marginal dispatch to coal when gas > ~$4–4.50/MMBtu, raising power-plant spark spread volatility and lifting coal mine EBITDA for 3–12 months. Financial cross‑assets: higher energy-driven CPI risks push short-duration Treasuries wider, support commodity FX (AUD, CAD), lift coal and LNG contracts, and raise realized vol in power and nat‑gas options.

Risk assessment: Tail risks include a swift regulatory clampdown on data‑centre emissions or new restrictions on coal plant operations (high-impact, 6–18 months), or a sudden drop in LNG exports/European demand that collapses Henry Hub (3–9 months). Hidden dependency: domestic gas price is tightly coupled to LNG export volumes and pipeline constraints—so US energy prices are globalized. Catalysts to monitor: Henry Hub > $4.50/MMBtu, monthly LNG export cargo counts, proposed federal/state utility moratoria on new data‑centre hookups, and quarterly data‑centre load announcements.

Trade implications: Tactical plays favor short-dated asymmetric long in coal miners (Peabody BTU, Arch ARCH) and long exposures to large gas producers with LNG upside (EOG, EQT) while hedging utility/regulatory risk. Rotate into solar supply-chain leaders (FSLR, ENPH) on 12–24 month structural demand (solar +34% y/y) and consider data‑centre REITs (DLR) for secular leasing demand, but hedge power‑cost risk. Use options: 3–6 month call spreads on BTU/ARCH and 3‑month call on Henry Hub futures (> $4.50 trigger); employ pair trades (long BTU, short gas‑weighted utility ETF XLU) to isolate fuel mix exposure.

Contrarian angles: The market may overstate a sustained coal renaissance; financing, ESG divestment and faster storage rollout could cap coal’s multi‑year upside—treat coal longs as mean‑reversion/seasonal trades with tight stops. Conversely, data‑centre load growth is underappreciated in utility capex plans—opportunity to buy targeted REITs and specialist power‑infra if capex announcements lag demand. Historical analogue: 2018–19 coal blips reversed when gas supply eased; set explicit exit thresholds (Henry Hub falling below $3.25 or utility capex >$X).

Key Decisions for Investors

• Establish a tactical 2–3% long position in Peabody Energy (BTU) and Arch Resources (ARCH) combined (1–1.5% each) via 3–6 month call spreads ~20% OTM to capture coal upside if Henry Hub remains > $4.00/MMBtu; hard stop if spreads compress 30% or Henry Hub < $3.25 for two consecutive weeks.
• Establish a 2–3% long position in large US gas/LNG producers EOG Resources (EOG) and EQT (EQT) split equally for 6–12 months to ride export-driven price support; hedge 25% of position by shorting the utility ETF XLU to isolate commodity beta.
• Overweight solar supply-chain: initiate 2% position in First Solar (FSLR) or Enphase (ENPH) for 12–24 months given 34% YoY solar growth; add on any pullback >15% from entry; exit tranche if quarterly installations growth decelerates below +10% y/y.
• Buy 3‑month Henry Hub call (or UNG call) sized 0.5–1% of portfolio as volatility hedge, with target if HH > $4.50/MMBtu to add incremental energy longs; unwind if HH < $3.25 for 2 weeks.
• Pair trade for 3–9 months: long Digital Realty (DLR) 1–2% and short 1% of a regulated power utility (e.g., NextEra NEE or XLU) to capture data‑centre demand premium while hedging rising wholesale power costs; close if regulator announces moratorium on new data‑centre hookups or if DLR leasing spreads compress >20%.
