The clean energy transition isn’t just a trend anymore; it’s reshaping how the world produces and consumes power. For investors, clean energy ETFs bring a growing number of opportunities to back companies driving this shift, from solar and wind to hydrogen, storage, and even carbon markets.
In this guide, we’ll spotlight the top clean energy ETFs on InvestEngine in 2025, show how they compare, and highlight a few others worth keeping on your radar.
What are clean energy ETFs?
Clean energy ETFs are investment funds that bundle together stocks of companies working in renewable and low carbon technologies. Instead of picking individual solar, wind, or battery firms, investors can buy shares in a single ETF and instantly gain diversified exposure to the broader clean energy sector.
These funds often include companies involved in:
- Renewable power generation (solar, wind, hydro, geothermal)
- Clean technology manufacturing (solar panels, wind turbines, batteries)
- Grid and storage solutions (smart grid technology, energy storage, hydrogen)
- Low carbon infrastructure and utilities
Why clean energy ETFs remain popular with UK investors in 2025
For UK investors, clean energy ETFs are still popular in 2025 for a number of reasons. Here’s why:
- Net-zero push: With the UK locked into its 2050 climate goals, there’s strong policy backing for renewables.
- Growing appetite for ESG: More people, both everyday savers and big institutions, want investments that align with sustainability values.
- Tax-friendly investing: Because ETFs can sit inside ISAs and SIPPs, they’re an easy, tax efficient way to build long-term exposure.
- Balancing portfolios: Clean energy offers a welcome alternative to traditional oil and gas stocks, which can be volatile.
It’s a mix of principle and practicality: investors get to support the energy transition while also keeping an eye on potential returns.

Key factors to consider when choosing a clean energy ETF
Not all clean energy ETFs are built the same. Before picking one, it’s worth weighing a few key points:
Focus and holdings
Some ETFs lean heavily into solar or wind, while others spread across broader themes like smart grids, batteries, or low carbon utilities. Check what’s inside to make sure it matches your outlook.
Geographic exposure
Do you want global coverage, or would you prefer a fund that concentrates on regions like the US, Europe, or emerging markets such as China? Geography can make a big difference in both growth potential and risk.
Fund size and liquidity
Larger ETFs with more assets under management (AUM) often trade more smoothly and with tighter spreads, which can lower your costs when buying and selling.
Fees (TER/expense ratio)
Even small differences in fees add up over time. Compare expense ratios to see if the fund offers good value for its strategy.
Performance and track record
Past returns don’t guarantee future results, but a consistent track record can give confidence in how the ETF behaves in different market conditions.
Fit with your portfolio
Finally, think about how the ETF complements what you already own, whether you’re adding a growth theme, diversifying away from fossil fuels, or looking for ESG exposure.

Performance trends and outlook for clean energy ETFs
Clean energy ETFs have bounced back in 2025, though not all themes are moving at the same pace.
Of course, past performance is not a reliable indicator of future returns. These are meant to provide an illustrative view of the sector.
- Broad recovery: Diversified funds like iShares Global Clean Energy and L&G Clean Energy have posted solid gains as demand for renewables and storage grows.
- Policy pressure on solar: Talk of phasing out U.S. tax credits has weighed on the Invesco Solar Energy ETF, highlighting how sensitive the sector is to policy shifts.
- Thematic plays: The Amundi Global Hydrogen ESG Screened ETF remains volatile as hydrogen projects scale up, while the SparkChange Physical Carbon EUA has been lifted by higher European carbon prices.
- Steadier options: Broader transition funds, such as WisdomTree Renewable Energy and J.P. Morgan Carbon Transition Global Equity, have provided a smoother ride for investors.
Outlook for 2025/2026
Investors will be targeting continued growth in clean power and storage, but there may be uneven performance across themes. Solar may stay choppy, while diversified and carbon linked funds could be steadier. Hydrogen remains a higher risk but could benefit if large projects gain more momentum.
