There is a certain irony in pairing the words "Trump" and "Green New Deal". The 47th President spent the better part of a decade deriding the original Green New Deal as a "socialist fantasy", and his second-term agenda — codified in a flurry of executive orders since January 2025 — has set about dismantling much of the Biden-era Inflation Reduction Act (IRA). And yet, eighteen months in, a paradox has emerged that UK investors cannot afford to ignore. Some of the same policies designed to revive American Hydrocarbons, reshore Manufacturing and weaponise tariffs are inadvertently catalysing a different kind of green build-out: a nuclear renaissance, a domestic critical minerals industry, and the largest grid expansion in a generation, much of it driven by artificial intelligence.

Whether you read the Trump energy stack as the anti-Green New Deal or as an accidental industrial policy for low-carbon hardware, the global economic consequences are now unmistakable. From the share prices of Vestas and Orsted in Europe to the order books of CATL and LG Energy Solution in Asia, from sterling-denominated funds like Greencoat UK Wind to LSE-listed Ceres Power, Capital is being repriced around a new American energy doctrine. This article unpacks both readings, examines the latest developments as of May 2026, and considers what it all means for British investors.

Background: From IRA to "Drill, Baby, Drill"

To understand where we are, it helps to remember where we came from. The 2022 Inflation Reduction Act committed roughly $370bn (and, by some Goldman Sachs estimates, more than $1.2 trillion over a decade) in tax credits, Loan guarantees and direct spending for clean energy, electric vehicles, hydrogen, carbon capture and domestic Manufacturing. It was, in effect, the United States' belated answer to a decade of Chinese industrial policy in solar, batteries and EVs.

The IRA's hidden constituency

By the time Donald Trump returned to the White House in January 2025, more than 80% of announced IRA-linked Manufacturing Investment had landed in Republican-leaning congressional districts. Battery gigafactories in Georgia, Tennessee, South Carolina and Kentucky; solar module plants in Ohio and Alabama; the rebuilt Vogtle nuclear units in Georgia. Senators from these states — including several who had voted against the IRA — quickly became its quiet defenders.

Trump's energy doctrine

The President's stated doctrine is straightforward: maximise domestic oil, gas and coal production; restore "energy dominance"; reshore strategic Manufacturing behind a high Tariff wall; and treat China as a systemic economic rival. The headline measures since inauguration have included Withdrawal (again) from the Paris Agreement, the lifting of the LNG export pause, an expansion of federal Lease sales, and an aggressive use of Section 232 and Section 301 tariffs on steel, aluminium, EVs and Chinese clean-tech imports.

What makes the picture more complex than a simple "fossil fuels good, renewables bad" story is the parallel push on nuclear power and critical minerals — both of which sit, awkwardly for the political narrative, squarely within the low-carbon transition.

Latest Developments: The May 2026 Snapshot

Eighteen months into the second term, several strands have crystallised. Each carries direct implications for global Commodity markets, Equity sectors and the cost of Capital for clean energy projects worldwide.

IRA rollback — partial, not total

The "One Big Beautiful Bill" passed in mid-2025 trimmed, but did not eliminate, the IRA's headline credits. The Section 45X advanced Manufacturing Credit was preserved for batteries, critical minerals and solar wafers, but the consumer-facing 30D EV Credit was phased out by the end of 2025. The 45Y and 48E technology-neutral electricity credits were narrowed, with stricter "foreign entity of concern" rules effectively excluding Chinese-linked Supply chains. Hydrogen's 45V Credit survived in diluted form. The result: a messier, more conditional incentive regime, but not the wholesale repeal many had feared.

A nuclear executive order blitz

Perhaps the most consequential — and underreported in the UK press — has been the cluster of executive orders signed in May and October 2025 to accelerate nuclear deployment. These directed the Nuclear Regulatory Commission to overhaul its licensing framework, set a target of quadrupling US nuclear capacity by 2050, fast-tracked small modular reactor (SMR) test reactors at Department of Energy sites, and authorised reactivation studies for shuttered plants. Westinghouse's AP1000 design has been positioned as the workhorse, with renewed interest from utilities in the Carolinas and Texas.

AI, data centres and the gas-to-power surge

US electricity Demand, flat for two decades, is now forecast by the EIA to grow by 15-20% by 2030, driven overwhelmingly by AI data centres, reshored Manufacturing and electrification. ERCOT and PJM interconnection queues are bursting. Hyperscalers — Microsoft, Amazon, Google, Meta — have signed power purchase agreements with everything from Constellation's restarted Three Mile Island Unit 1 to behind-the-meter Natural Gas turbines. Combined-cycle gas turbine orders at GE Vernova and Siemens Energy are sold out into 2029.

Tariffs and the critical minerals scramble

The 60% baseline Tariff on Chinese imports, layered on top of Section 232 duties on steel and aluminium and a 100% Tariff on Chinese EVs and batteries, has triggered a global reshuffling. Western miners — MP Materials in rare earths, Lynas in Australia, Albemarle and SQM in lithium, and emerging names like Sigma Lithium — have benefited from explicit Department of Defense offtake agreements and price floors. The flip side: Chinese overcapacity has been redirected to Europe, Latin America and South-East Asia, depressing global module and battery prices.

Market and Economic Impact

The market response has been neither uniformly bullish nor bearish for clean energy — it has been highly bifurcated, and that bifurcation is itself the story.

Winners: nuclear, gas infrastructure, US-aligned miners

Nuclear-exposed equities have led the rally. Constellation Energy, Vistra and Public Service Enterprise Group have re-rated sharply on data centre PPAs. Cameco and Kazatomprom benefited from a uranium price that pushed above $100/lb in late 2025. Among equipment names, BWX Technologies and NuScale have attracted speculative flows on SMR optionality. In the UK, Rolls-Royce SMR — still pre-commercial — has been a notable beneficiary of the read-across, helping to lift the parent group's share price.

Gas infrastructure has been the other clear winner. Cheniere Energy, EQT and Williams Companies have rallied on LNG export expansion and domestic Demand. Pipeline operators like Energy Transfer have seen renewed permitting momentum.

Critical minerals names have been more volatile but structurally supported. MP Materials secured a multi-year price floor for neodymium-praseodymium oxide; Albemarle has stabilised after a brutal 2024 lithium downcycle.

Losers: residential solar, offshore wind, pure-play EVs

The casualties are equally clear. Residential solar — Sunrun, SunPower's successors, Enphase — has suffered from the loss of the 25D Credit and net metering reform in key states. Offshore wind has been savaged: Orsted booked further impairments on its US East Coast portfolio, and Equinor walked away from Empire Wind 2. Siemens Energy's Gamesa division remains a problem child, though the gas turbine Business has more than offset the drag.

Pure-play EV makers have struggled with the Credit phase-out. Rivian and Lucid have seen funding pressures intensify; Tesla, with its diversified energy storage and AI businesses, has weathered better. Chinese players — BYD, NIO, XPeng — have been functionally locked out of the US market and are now competing fiercely in Europe, putting pressure on incumbents like Stellantis and Volkswagen.

Oil majors: cautious Capital discipline

ExxonMobil, Chevron, ConocoPhillips and Occidental have not, contrary to the political rhetoric, dramatically ramped up capex. Shareholder pressure for Buybacks and dividends remains the dominant force. European majors — Shell, BP and TotalEnergies — have quietly walked back some renewables targets, with BP's pivot back toward Hydrocarbons under its current strategy now looking better-timed than it did a year ago.

Macro: dollar, Deficit and emerging markets

The macroeconomic backdrop is equally important. The trade-weighted dollar has remained firm, supported by Tariff Revenue, reshoring inflows and a Federal Reserve that has been slow to cut. The US trade Deficit has narrowed modestly but remains structurally large. Emerging markets reliant on dollar funding — Turkey, Argentina, parts of sub-Saharan Africa — have faced renewed stress. Inflation, having dipped in 2024, has proved sticky in 2025-26 as Tariff pass-through and energy price Volatility offset disinflation in services.

Investor Implications

For UK investors, the practical question is how to position portfolios for a world in which American policy is simultaneously hostile and helpful to different parts of the energy transition.

UK-listed beneficiaries and casualties

On the positive side of the ledger sit several London names. SSE and National Grid continue to benefit from a domestic capex super-cycle, partly insulated from US policy noise. Rolls-Royce has gained from nuclear sentiment and defence spending. Drax, controversial as ever, finds itself relevant again as dispatchable capacity is repriced. Among renewables-focused Investment trusts, Greencoat UK Wind and Foresight Solar trade at persistent discounts to NAV — a function of higher gilt yields rather than US policy directly, though sentiment around the global transition does not help.

The clearer casualties are UK hydrogen and fuel-cell names. ITM Power and Ceres Power have struggled as global green hydrogen project pipelines have thinned and the US 45V Credit has been narrowed. Johnson Matthey, with significant catalyst exposure, sits awkwardly between the EV slowdown and a possible hydrogen revival.

Sector rotation and portfolio construction

A balanced reading suggests three structural themes worth considering: power infrastructure (transmission, gas turbines, nuclear services); critical minerals and processing capacity outside China; and AI-adjacent utilities. Conversely, undifferentiated exposure to global solar Manufacturing, residential solar financing, and pure-play EV start-ups carries asymmetric downside.

Funds such as the iShares Global Clean Energy ETF have underperformed broad Equity indices for three consecutive years. Investors seeking transition exposure may need to think more granularly — separating the "hard hat" infrastructure layer from the "consumer technology" layer, which is far more policy-sensitive.

Currency and geographic considerations

For sterling-based investors, the strong dollar has flattered US Equity returns. A Reversal — should the Fed accelerate cuts in late 2026 — would erode some of that tailwind. Hedged share classes deserve a look at current FX levels.

Risks: Where the Thesis Could Break

No analysis would be complete without acknowledging the considerable risks attached to the current regime.

Policy Reversal risk

Mid-term elections in November 2026 could shift the balance in Congress. A Democratic House could constrain further Tariff escalation and protect what remains of the IRA. Conversely, deeper rollbacks remain possible if Republicans expand their majority. Either outcome would force another round of repricing.

Tariff-driven Inflation and rates

If Tariff pass-through proves more inflationary than the administration expects, the Federal Reserve may keep rates higher for longer. Long-duration Assets — including most renewable infrastructure trusts — would suffer further NAV pressure.

Supply chain dislocation

The reshoring thesis assumes Western capacity can be built quickly enough to absorb Demand. The reality is that permitting, skilled labour and grid interconnection remain binding constraints. A messy transition could mean both higher prices and missed deployment targets.

Geopolitical escalation

A serious deterioration in US-China relations — over Taiwan, over technology export controls, over rare earths — could trigger retaliation that disrupts the very Supply chains Trump is trying to reshore. The 2010 Chinese rare earth embargo against Japan is the historical precedent investors should keep in mind.

Climate physical risk

Finally, the underlying climate trajectory has not paused for politics. Insurance markets in Florida, California and parts of the Gulf Coast continue to harden. Physical climate risk is being priced into property, infrastructure and sovereign Debt regardless of federal policy direction.

Outlook: Two Scenarios for 2027 and Beyond

Looking ahead, two broad scenarios bracket the range of plausible outcomes.

The "accidental green industrial policy" scenario

In this reading, Trump's Tariff wall, nuclear push and AI-driven power Demand combine to deliver a leaner, more domestically anchored low-carbon build-out. Solar and wind grow more slowly than under the Biden trajectory, but nuclear, grid and storage accelerate. Chinese overcapacity floods Europe and emerging markets, lowering the global cost of decarbonisation even as US headlines turn hostile. Global emissions plateau by the late 2020s rather than falling sharply, but the hardware base for a deeper transition in the 2030s is laid.

The "lost decade for clean tech" scenario

In the alternative reading, IRA rollback proves more damaging than the partial repeal suggests. Capital flight from offshore wind and residential solar becomes contagion. The Paris Agreement framework frays as other major emitters quietly retreat from commitments, citing US Withdrawal as cover. COP31, scheduled for late 2026, becomes a venue for recriminations rather than progress. Global emissions resume a clear upward trajectory, with all the attendant physical and transition risks.

The truth is likely to lie somewhere between these poles, with significant variation by sub-sector and geography. The Investment implications differ sharply depending on which scenario dominates.

Conclusion

Donald Trump is not, by any conventional definition, the architect of a Green New Deal. His rhetoric, his cabinet and his executive orders make plain his hostility to the climate movement and its preferred policy instruments. Yet the unintended consequences of his industrial, trade and energy doctrine are reshaping the global green economy in ways that defy the headlines. A nuclear renaissance, a critical minerals reshoring drive, an AI-led power Demand surge and a Tariff-induced reordering of global Supply chains together constitute a kind of accidental industrial policy for parts of the low-carbon transition — even as other parts, particularly residential solar and offshore wind, suffer real damage.

For UK investors, the lesson is one of granularity. Broad clean-energy exposure has underperformed and may continue to do so. But within the transition, specific sub-sectors — nuclear services, grid infrastructure, dispatchable power, critical minerals — are enjoying tailwinds that look durable across political cycles. Maintaining a balanced, diversified approach, with attention to currency, duration and policy risk, will matter more than betting on any single political narrative. The paradoxes of the Trump energy era are real, and they are likely to persist long after the slogans have faded.
