Best Clean Energy ETFs in Europe 2026

Clean energy is no longer a niche theme. Solar, wind, storage and grid modernisation now compete head-to-head with fossil fuels on cost. European investors get a wide menu of thematic ETFs to tap into this transition — but picking among them is tricky. This guide ranks the top 5 clean energy ETFs available to retail investors in Europe in 2026.

Why clean energy?

• Policy tailwinds: EU Green Deal, IRA in the USA, China's 2030 renewables target
• Cost curve: Solar LCOE has dropped ~90% in the last decade
• Long-term demand: Data centres (AI) are driving the largest electricity demand surge in 20 years
• Capital flows: Renewables investment exceeded $1.7 trillion globally in 2024

That said, clean energy ETFs are volatile — they dropped 50%+ between 2021 highs and 2023 lows before rebounding. They are a satellite position, not a core holding.

Comparison table

Regional exposure

Most clean energy ETFs are heavily weighted to:

• USA: 40-50% (First Solar, Enphase, NextEra)
• Europe: 25-35% (Vestas, Iberdrola, Ørsted)
• China: 10-15% (Contemporary Amperex, LONGi)
• Rest: 5-10%

Risks and opportunities

Risks:

• Interest rate sensitivity — higher rates hurt growth valuations and renewable project financing
• Policy reversal risk (e.g. US IRA rollback scenarios)
• Commodity price volatility (polysilicon, lithium)
• Concentration in a handful of large names

Opportunities:

• AI-driven electricity demand surge
• Grid modernisation buildout
• Storage cost curve continuing to fall
• 50%+ drawdown from 2021 peaks = attractive entry for long-term investors

What percentage of portfolio?

Treat clean energy as a satellite position: 3-10% of your equity sleeve at most. If you already hold IWDA or VWCE, your portfolio has exposure to Tesla, NextEra, First Solar etc. anyway — clean energy ETFs overweight that exposure.

Example portfolios:

• Conservative satellite (5%):
  • 85% IWDA + 10% EIMI + 5% INRG
• Thematic tilt (10%):
  • 70% VWCE + 20% VUAA + 10% RENW

FAQ

Are clean energy ETFs a good investment? For long-term investors (10+ years), likely yes — the structural tailwinds are real. For short-term returns, they are very volatile (40-50% drawdowns are normal).

INRG vs RENW — which is better? INRG is larger and more liquid. RENW is cheaper (0.49% vs 0.65%). For DCA investors, RENW saves ~16 PLN/year per 10,000 PLN invested.

Is this ESG? Clean energy ETFs score high on "E" (environment) but aren't full ESG funds. For pure ESG exposure, consider a broad ESG ETF like SUSW or EUSRI.

Should I buy clean energy after the 2021-2023 drawdown? Valuations are materially lower than the 2021 peak. Whether that's a buying opportunity or a value trap depends on interest rates and policy. DCA over 12-24 months reduces timing risk.

Why not just buy Tesla or First Solar directly? Single-stock risk. Clean energy ETFs spread that risk across 50-100 companies.

Historical performance context

Clean energy as a theme had extraordinary returns in 2019-2021 (INRG +250% over 24 months), followed by a brutal drawdown of ~55% into mid-2023 as interest rates spiked. Since late 2024, the sector has been in a choppy recovery as rate cuts priced in. Long-term (10+ year) investors should expect 30%+ drawdowns as normal.

Tax considerations (Poland)

Belka tax (19%) applies to realised capital gains. Because INRG/RENW are accumulating, you only pay tax when you sell. In IKE (post-age-60), capital gains are tax-free — a significant advantage for satellite positions held 15+ years.

How to DCA into clean energy

Given the volatility, lump-sum investing is risky. A DCA approach (e.g. 500 PLN monthly into INRG or RENW) smooths out entry prices. If you're using XTB's 0% commission tier, even 200-300 PLN monthly purchases make economic sense.
