When you stand outside a Hull wind turbine manufacturing factory on a Tuesday morning, the size of what’s being constructed immediately becomes very tangible. The massive blades, which are longer than the wings of a commercial aircraft, move slowly across the yard on flatbeds in the direction of the docks. Outside a prefabricated canteen, workers wearing high-visibility jackets have lunch in the bitter weather. What’s taking place here is not theoretical.
Regardless of the political debates around it, the energy revolution has evolved into industrial infrastructure. On the opposite side of that reality, money is moving toward it with a newfound urgency that seemed unlikely just a few years ago in fund management offices in Edinburgh and London.
The past few years have been challenging for alternative energy ETFs. Following the initial excitement of 2020 and 2021, when net-zero promises and pandemic-era stimulus brought in billions of dollars for clean energy financing, the industry struggled for the better part of two and a half years.

Growth-oriented stocks were severely impacted by rising interest rates, and capital-intensive renewable infrastructure projects were particularly heavily hit. One of the most popular ETFs on the UK market, the iShares Clean Energy UCITS ETF, spent a large portion of that time trying the endurance of investors who had invested close to the top. Then, at some point in late 2025, things started to alter. Over the course of six months, the fund increased by more than 40%. Recoveries of that nature are not overlooked.
That comeback was caused by a number of factors that came about more or less at the same time, and tariffs from the Brexit phase play a bigger role in that narrative than most reporting recognizes. Energy-related supply chains, such as parts for solar installations, specialty cables, and inverter equipment, have become more expensive and complex since the UK officially exited the EU single market in 2021.
Previously, these supply chains crossed the Channel with no difficulty. As a result, local and nearshore energy production has become more appealing in comparison, pushing renewable energy economics closer to competitiveness even prior to the jump in oil prices that followed growing concerns over Iran’s energy exports through 2025.
The more dramatic accelerant was that oil shock. Genuine shift in institutional portfolios was driven by the way that rising fossil fuel prices make wind and solar appear much more reasonable on a spreadsheet. After reducing their exposure to renewable energy, investors began to rebuild their positions.
As fund managers balanced their relative protection from commodity price volatility against the ongoing earnings uncertainties of traditional energy majors, stocks like Ørsted and Vestas, both listed in Copenhagen but widely held through ETF structures throughout Europe, attracted fresh interest. Investors appear to think that the difference between the cost exposure of fossil fuels and the cost stability of renewable power is not going to close anytime soon, or at least they are prepared to wager.
Observing the flow statistics from early 2026 gives the impression that this isn’t just emotion chasing. According to ETF Trends, the ALPS Clean Energy ETF’s year-to-date gains increased to 6.66% by March 2026. However, what’s more noteworthy is the buying composition, which consists of both institutional money flipping from overpriced traditional energy positions and retail investors returning after sitting out the dip.
The term “energy security” is frequently used in these discussions, and it has significant weight in the post-Brexit, post-Ukraine, and post-Iran disruptive investment landscape. Owning petroleum distribution infrastructure that is independent of a stable geopolitical corridor has evolved from an ESG talking point to a risk management rationale.
Underneath all of this, policy has supplied structural support. The European Investment Bank’s increased funding and the EU Grid Package, which aims to expedite the construction of transmission infrastructure required to transport renewable energy across borders, have both improved the long-term project economics for clean energy producers operating on the continent.
Since the UK is no longer a part of the EU’s policy framework, it is forging its own route, which has drawbacks in terms of market access as well as possibly some regulatory design freedom. Over the next ten years, it’s still uncertain if the UK’s post-Brexit energy policy framework will ultimately support or impede domestic renewable development.
This uncertainty coexists with a more pressing one: UK-listed renewable infrastructure funds, such as Greencoat UK Wind and The Renewables Infrastructure Group, have been trading at significant discounts to their net asset value. This situation reflects persistent investor apprehension regarding long-duration asset pricing and interest rate sensitivity. Depending on your time horizon, the discount may be an opportunity or a problem.
The NAV discount in closed-end funds is less significant to ETF buyers who view the industry through a wide index. However, it does make one wonder if the ETF market’s exuberance truly accounts for the fundamental difficulties that the sector’s underlying assets continue to face.
All of this does not lessen the fact that this is undoubtedly a real and long-lasting trend. Investment in the global energy transition reached a record in 2025, and although the yearly growth rate has moderated from the explosive 27% pace of 2021 to something closer to 8%, the total capital flows are still very high.
Even if Brexit’s tariff interruptions have been unpleasant for supply chains, they have unintentionally made the argument for expanding the energy system’s localization. When oil prices inevitably level off, that argument won’t go away. No matter what the headlines say, the turbine blades in Hull continue to move toward the docks.
