Clean Energy ETF Comparison 2026
Solar, wind, hydrogen: clean energy ETFs bundle the winners of the energy transition. The 2020/21 boom was followed by a sharp pullback — we compare the most important products with ISIN and TER and give an honest assessment of what the sector can do today and what it cannot.
What’s inside a clean energy ETF?
Clean energy ETFs invest in companies across renewable energy — solar and wind manufacturers, grid operators, hydrogen specialists and suppliers. They are narrow thematic funds: a few dozen holdings, often with a heavy weighting in individual names. That means above-average swings in both directions.

The honest assessment: boom, crash, reality
In 2020/21 clean energy ETFs surged — fuelled by low interest rates and climate euphoria. Then came the harsh pullback: rising rates, project costs and overcapacity often pushed prices down by more than half. Hydrogen was hit even harder. The energy transition is real and long-term, but it does not run in a straight line — anyone investing here needs staying power and a tolerance for volatility.
Pure hydrogen ETFs bet on a technology that is still economically in its infancy. Many of the companies they hold are loss-making and dependent on subsidies and politics. This is a high-risk wager on the future, not a solid core investment — so size it small accordingly.
How much belongs in your portfolio?
- As a satellite: at most 5–10 % of your equity allocation, deliberately as a bet on the energy transition.
- Not as a core: the narrow diversification and high volatility make clean energy unsuitable as a portfolio foundation.
- Mind the overlap: the big energy-transition winners are already partly in your world ETF.
🌍 Tax
A thematic ETF holding equities is an equity ETF and is taxed like any other share fund. Rules vary by country, so check your local treatment. In Germany, for example, equity ETFs receive a 30 % partial exemption (Teilfreistellung), alongside the flat capital gains tax (25 % plus solidarity surcharge on the taxable portion), the advance lump sum on accumulating versions and the annual saver’s allowance of €1,000 — just like any equity ETF.
FAQ — Clean Energy ETF 2026
Which clean energy ETF is the best?
The broadest and best-known is the iShares Global Clean Energy (IE00B1XNHC34), which tracks the major renewables winners globally. The cheapest in the hydrogen segment is the L&G Hydrogen Economy (IE00BMYDM794, 0.49 %). “Best” depends on whether you want broad exposure to renewable energy or a targeted bet on hydrogen — the latter is considerably more speculative.
Why did clean energy ETFs fall so sharply?
After the 2020/21 boom, rising interest rates, higher project and financing costs and overcapacity (in solar, for instance) weighed on the sector. Many holdings lost more than half their value. The long-term energy transition remains intact, but the path there is volatile.
Is a hydrogen ETF worth it?
Hydrogen is a theme of the future, but still economically immature. Many companies are loss-making and dependent on subsidies. A hydrogen ETF is therefore highly speculative and only makes sense as a small add-on for risk-tolerant investors with a long horizon.
Isn’t clean energy already in my world ETF?
Partly yes — large utilities and industrial groups with a renewables business are already weighted in the MSCI World or FTSE All-World. A thematic ETF deliberately increases that weighting and additionally adds smaller, pure clean energy specialists that barely feature in the broad index.
