Clean Energy ETF EU 2026: INRG vs RENW vs L&G UCITS

TL;DR

EU investors have three primary UCITS routes into clean energy: iShares Global Clean Energy (INRG/IQQH) at 0.65% TER, L&G Clean Energy (RENW) at 0.49% TER, and HANetf S&P Global Clean Energy (ZERO) at 0.59% TER. AUM ranges from ~EUR 110M (ZERO) to ~EUR 2.6B (INRG). 5-year annualised return is negative to flat (-3% to +1%) after the 2021 peak crash — clean energy is the worst-performing thematic UCITS category over 3 years. Key risks: subsidy dependency (IRA repeal risk in US, REPowerEU implementation lag), rate sensitivity (most names trade as long-duration cash flows), and Chinese supply glut crushing solar panel margins.

Why Clean Energy in 2026

Global clean energy capacity additions hit 560 GW in 2024, with 2026 IEA projections at 720 GW. Drivers:

• Policy backbone. EU REPowerEU targets 45% renewable share by 2030; US IRA committed USD 369B for clean energy tax credits (subject to ongoing political debate); China's 14th Five-Year Plan continues massive deployment.
• LCOE trajectory. Utility-scale solar levelised cost of energy is now USD 30-40/MWh, half the 2018 level. Onshore wind around USD 30-50/MWh. Both competitive with new-build gas in most markets.
• AI data centre demand. Hyperscaler PPAs for renewables jumped 3x in 2024-2025; Microsoft, Google, Amazon signed ~30 GW combined.
• Storage maturity. Lithium battery storage prices fell from USD 161/kWh in 2022 to USD 115/kWh in 2024; grid-scale BESS deployment accelerated.
• Headwinds. Higher interest rates compressed margins on long-duration projects; offshore wind faced cost overruns (Ørsted, Equinor write-offs); Chinese solar oversupply crushed pricing power for First Solar competitors.

Historical data shows clean energy as a thematic has been highly cyclical: massive 2020-2021 outperformance (+200% peak), brutal 2022-2023 drawdown (-60%+), and choppy 2024-2025 base-building. Many thematic investors include clean energy as a long-horizon decarbonisation bet rather than a near-term outperformance trade.

Top UCITS Clean Energy ETFs Comparison

INRG is the dominant ETF by AUM and the oldest in the category. After the 2021 S&P Global Clean Energy index reconstitution (expanded from 30 to ~100 names), the methodology became broader and less concentrated.

First Solar, Enphase Energy, SolarEdge, Vestas Wind Systems, Iberdrola, Orsted, NextEra Energy, EDP Renovaveis, Plug Power, Bloom Energy, Constellation Energy, Schneider Electric, ON Semiconductor, ABB, Siemens Energy, China Yangtze Power, Longi Green Energy.

Overlap: roughly 65-75% between INRG and RENW. INRG (post-2021 reconstitution) covers ~100 names; RENW uses a different Solactive index with ~50 names and skews more European.

Geographic exposure (INRG approx end-2025):

• United States: 40%
• China: 11%
• Spain: 8%
• Denmark: 7%
• Brazil: 6%
• Germany: 5%
• Other: 23%

Sub-segment mix (typical clean energy ETF):

• Solar: 28%
• Wind: 21%
• Utilities (renewable IPPs): 24%
• Hydrogen / fuel cells: 8%
• Grid / power electronics: 13%
• Other (geothermal, hydro): 6%

WRNW and ZERO tilt purer (excluding diversified utilities like NextEra); they're higher-beta, lower-AUM plays.

Performance Snapshot

Historical data (approximate annualised total return in EUR, to end-2025):

Clean energy is the only major thematic UCITS category with negative 3-year annualised returns. The 2021 peak (driven by ESG inflows and ultra-low rates) and the 2022-2023 collapse (rate hikes, supply-chain inflation, project cost overruns) wiped out roughly half of the peak value.

Tracking error: INRG 0.15-0.20% annualised; smaller funds higher at 0.4-0.6%.

---

Does Clean Energy Outperform Broad Index After Fees

No, decisively not over 3 and 5 years. MSCI World delivered ~11.6% annualised versus -1.2% for INRG over 5 years. The gap is over 12% per year compounded — a EUR 10k in MSCI World became ~EUR 17.3k; the same in INRG became ~EUR 9.4k.

Over 10 years (capturing 2017-2020 boom), clean energy still roughly matches MSCI World but with much higher volatility. The investment case requires accepting cyclical drawdowns of 50%+ being normal and conviction that structural decarbonisation will reward patience over 10-20 years.

Total Cost for EU Investor

For a EUR 10,000 position in INRG held 5 years:

• TER: 0.65%/year = ~EUR 325 cumulative
• Spread (Xetra): ~0.10-0.15%
• Commission: typically EUR 0-1 at Trade Republic, free at Scalable plans
• FX impact: ~40% USD, 30% EUR, 11% CNY/HKD — most diverse FX mix of any thematic ETF

Total expected drag: ~0.70-0.85%/year — among the highest for any UCITS thematic, reflecting both TER and slightly wider spreads.

RENW at 0.49% TER is materially cheaper and worth considering if AUM/liquidity (~EUR 270M) is sufficient for your position size.

Tax Treatment by Country

• Germany. Equity ETF Vorabpauschale + 30% Teilfreistellung.
• France. Clean energy thematic ETFs are partly PEA-eligible if European-focused — INRG/RENW typically do NOT qualify because of US/Chinese weight >25%. CTO + PFU 30%.
• Italy. 26% on realised gains.
• Spain. 19-28% sliding scale.
• Netherlands. Box 3.
• Poland. 19% Belka on sale; PIT-38.

ESG-focused investors sometimes prefer Article 9 SFDR funds; INRG and RENW classify as Article 8 SFDR, ZERO as Article 9 SFDR — a differentiator for institutional and mandate-driven investors.

Broker Availability

Polish IKE/IKZE users: INRG (IE00B1XNHC34) has been available in BOSSA and mBank IKE since 2007 — strong listing tenure. RENW newer (2020) but typically supported.

When Clean Energy ETF Makes Sense

1. Long-horizon decarbonisation bet (10-20 years). Structural conviction that 2030/2050 net-zero policy will drive capex and consumer demand.
2. Diversified ESG sleeve. Investors with sustainability mandates use clean energy ETFs as a measurable Article 8/9 SFDR allocation.
3. Contrarian DCA after 50% drawdown. Some allocators view post-2022 levels as a reset opportunity; valuations on EV/EBITDA are at 5-year lows for many constituents.
4. Hedge against fossil-fuel divestment. Pairs naturally with reduced or zero oil & gas allocation.

---

When Clean Energy ETF Does NOT Make Sense

1. Investor needing reliable returns. 3-5 year track record is negative; the thesis is unproven on a recent-cycle basis.
2. Rate-sensitive portfolio already. Clean energy is the most rate-sensitive equity theme; long-duration projects amplify yield moves.
3. Political-risk averse. US IRA is a political football; subsidies and tax credits can be amended or repealed.
4. PEA-only French investors. No wrapper, full PFU drag on a thematic with poor recent returns.
5. Pure tech-allocation seekers. Clean energy is closer to industrial/utility than to tech; growth-style filters often exclude it.

---

Sector-Specific Risks

• Subsidy dependency. US IRA Production Tax Credit (PTC) and Investment Tax Credit (ITC) drive ~30% of project IRR for many US renewables. Repeal risk is non-trivial.
• Chinese supply glut. Solar module prices fell ~50% in 2023-2024 driven by Chinese overcapacity; First Solar (US-only IRA-protected) holds up; SolarEdge, Enphase suffered.
• Rate sensitivity. Renewable projects have payback periods of 8-15 years; every 100 bps rise in long-end yields compresses NPV by 12-18%.
• Offshore wind cost overruns. Ørsted wrote off USD 5B+ in 2023-2024; Equinor cancelled projects; supply chain inflation hit hard.
• Concentration in top 5. First Solar + Enphase + Iberdrola + NextEra + Vestas can be 35-40% of ETF weight depending on index — idiosyncratic shocks move the ETF noticeably.
• Hydrogen disappointment. Plug Power, Bloom Energy down 70-90% from 2021 peaks; green hydrogen economics remain challenged at scale.

Worked Example: EUR 10,000 DCA Over 5 Years

EUR 167/month into INRG for 60 months (EUR 10,020 total). Using trailing 5-yr annualised return of -1.2% net of TER:

• Final value (approximate): EUR 9,720
• Net loss: -EUR 300 (-3.0%)

Same DCA into VWCE:

• Final value: EUR 13,180
• Net gain: EUR 3,160 (+31.5%)

Difference: ~EUR 3,460 in favour of broad-market VWCE. This is the opportunity cost of a 5-year thematic bet that went wrong. The DCA structure cushioned the drawdown (vs lump sum at 2021 peak which would have been ~-40% on the original capital), but cyclical themes test investor discipline.

Polish Reader Angle

For Polish investors:

• IKE/IKZE viability. INRG is widely available in BOSSA IKE and mBank IKE; RENW typically supported. Inside IKE the negative 5-year performance hurts equally — but the tax-free compounding on recovery is more attractive than outside the wrapper.
• DTT relief. Ireland-domiciled ETFs get Ireland-US treaty WHT of 15% on US dividends; for INRG with ~40% US weight, the saving versus direct US stocks is meaningful (~50 bps annually on a 2% gross dividend yield).
• FX risk. Multi-currency basket (~40% USD, 30% EUR, 11% CNY) is the most diversified of any thematic — partly hedges single-currency moves.
• Polish renewables play. Local exposure (PGE, Tauron, Enea green capex) is not in INRG — for pure Polish renewables exposure, investors look at WIG-Energia or specific GPW names; thematic UCITS adds global diversification.

Tracking thematic allocation drift

A clean energy sleeve that started at 5% may now be 3% of portfolio after the 2022 drawdown — do you top up to maintain weight, or accept the drift as a market signal? Freenance tracks per-theme weight evolution, correlation to your broader holdings, and the Financial Freedom Runway impact of allocating contributions to laggards — making rebalancing decisions less emotional.

FAQ

Q: Is INRG the same as the US-listed ICLN? INRG and ICLN both track the S&P Global Clean Energy index — same exposure, different wrappers. ICLN is US-listed and not available to EU retail under MiFID II. INRG is the UCITS Ireland-domiciled equivalent.

Q: Why did INRG drop 60% from 2021 peak? Three forces: (1) 2021 inflows were driven by ESG mania at zero rates — both reversed; (2) supply-chain inflation crushed project IRRs; (3) the April 2021 index reconstitution diluted concentration just before the regime change.

Q: Should I prefer INRG (0.65%) or RENW (0.49%)? On cost, RENW wins by 16 bps. INRG has 10x the AUM and tighter spreads. Performance over 3 years roughly tracks within 1-2%. The decision often comes down to position size — for >EUR 5k positions, RENW's cost advantage outweighs the spread.

Q: Is hydrogen exposure in these ETFs? Yes, partially — Plug Power, Bloom Energy, ITM Power appear with low weights (typically 1-3% each). Pure hydrogen ETFs exist (HDRO, HTWO) but are even more volatile.

Q: Does the Trump-era IRA risk hurt clean energy thesis? A meaningful policy shift could remove 20-30% of US project IRR uplift. EU and Chinese demand is independent of US policy. The thesis is regional-mix sensitive; investors who want exposure without US risk look at European-only clean energy funds.

Q: Can clean energy work as a satellite to a broad ESG core? Yes — many investors run VWCE / ESG-core 80% + INRG/RENW 5% + other thematics 15%. Clean energy as a small satellite expresses values + thesis without dominating portfolio outcomes.

Q: What about pure-play solar versus diversified clean energy? Pure solar UCITS exposure is harder to find — INRG and RENW carry solar weights of 25-30%. Some thematic funds (HANetf Solar Energy is a notable historical example, with mixed AUM history) provided focused exposure but liquidity has been variable. For most retail investors, the diversified clean energy basket is more practical.

Q: How do hydrogen and storage fit in? Hydrogen names (Plug Power, Bloom, ITM) carry 1-3% weight each in major clean energy ETFs. Storage (Tesla energy division, Fluence, EnerSys) is included indirectly via diversified utilities. Dedicated hydrogen ETFs (HDRO, HTWO UCITS) exist but have even worse 3-year returns than broad clean energy.

Additional Considerations for Long-Horizon Investors

Hyperscaler PPA demand is a real catalyst. Microsoft, Google, Amazon, Meta together signed approximately 30 GW of new renewable PPAs in 2024 — equivalent to roughly 6% of total US renewable capacity additions for the year. AWS alone targets 100% renewable matching by 2025; Google moved to 24/7 carbon-free energy targets requiring firm renewables + storage, not just intermittent solar/wind. This creates a structural buyer cohort with USD 200B+ in combined capex budgets willing to pay above-market rates for clean power.

EU REPowerEU implementation lag. The headline numbers (45% renewable share by 2030, EUR 300B+ programme) are powerful, but member-state implementation has lagged. Permitting reform was the bottleneck — average time to permit a wind farm in Germany dropped from 6 years to 4 years (2024 reform), still slow versus 18-month US averages. Each acceleration unlocks order flow for Vestas, Siemens Gamesa, and balance-of-system suppliers in the ETFs.

First Solar as the IRA winner. Of the top INRG holdings, First Solar (FSLR) is uniquely positioned: US-only manufacturing qualifies for IRA Section 45X production tax credits worth USD 0.18-0.40 per watt depending on module type. FSLR earnings benefit by approximately USD 1.5B annually from these credits, materially uplifting reported EPS. If IRA is preserved through 2030, FSLR could compound at 20%+ — and FSLR is ~6-8% of INRG, so this single bet drives meaningful ETF performance.

The hydrogen disappointment as a feature, not a bug. Plug Power, Bloom Energy, ITM Power dropped 70-90% from 2021 peaks — clean energy ETFs that overweighted hydrogen got hit hardest. Going forward, the smaller hydrogen weights in current ETF rebalancings reduce drag from this segment. Green hydrogen at scale remains a 2030+ story.

Subsidy cliffs vs subsidy expansions. US IRA production tax credits run through 2032 with phase-out language tied to emissions targets. EU CBAM (Carbon Border Adjustment Mechanism) phased in 2024-2026 indirectly subsidises EU clean energy by penalising imports of high-emission steel/cement/aluminium — Iberdrola, EDP, Ørsted are indirect beneficiaries. Investors need to model both expansion and reversal scenarios for any 5+ year holding period.
