Best Clean Energy and Green ETFs
Clean energy ETFs bet on the transition to renewables. The thesis is strong. The recent performance has been painful. Here is what to know.
Don't have time? Here's what you need to know:
- 1Clean energy ETFs have lost 25-50% from their 2021 peaks despite the strong long-term thesis
- 2Most holdings are unprofitable and capital-intensive — structurally riskier than traditional energy
- 3Keep clean energy allocation under 3-5% as a speculative satellite position
- 4VTI already holds the profitable clean energy winners (NextEra, Tesla) without the startup risk
Clean Energy ETFs: Great Thesis, Tough Returns
The clean energy investment thesis is straightforward: the world is transitioning from fossil fuels to renewables, and companies building solar panels, wind turbines, and EV infrastructure should benefit. ICLN (iShares Global Clean Energy) surged 140% in 2020 as investors priced in a green energy boom. Then reality hit: rising interest rates, supply chain disruptions, and unprofitable business models sent ICLN down 50%+ from its peak.
Most clean energy companies are capital-intensive, unprofitable, and dependent on government subsidies. Rising rates increase their borrowing costs. Unlike mature energy companies (Exxon, Chevron) that generate massive cash flows, many clean energy firms burn cash while trying to scale. This makes clean energy ETFs structurally riskier than traditional energy or broad market funds.
Best Clean Energy ETFs Compared
| ETF | Focus | Expense Ratio | Holdings | 3-Year Return | Profitability of Holdings |
|---|---|---|---|---|---|
| ICLN | Global clean energy | 0.40% | 100+ | ~-25% | Mixed (many unprofitable) |
| TAN | Solar energy | 0.67% | 40+ | ~-35% | Low (capital-intensive) |
| QCLN | Clean edge green energy | 0.58% | 60+ | ~-20% | Mixed |
| PBW | Clean energy broad | 0.62% | 50+ | ~-40% | Low |
| FAN | Wind energy | 0.60% | 40+ | ~-30% | Mixed |
When Clean Energy Might Work in Your Portfolio
If you believe clean energy will outperform over the next 10-20 years despite recent losses, a small allocation (3-5%) is the appropriate bet. Clean energy is a structural trend — but structural trends can take decades to reward investors. The internet was a structural trend in 2000, yet internet stocks crashed 80% before eventually delivering massive returns.
The safer way to get clean energy exposure: own VTI or VOO, which already hold companies like Tesla, NextEra Energy, and First Solar. These broad index funds capture the clean energy winners without concentrating your portfolio in unprofitable startups.
Important: Clean energy ETFs have destroyed capital since 2021. ICLN is down 50%+ from its peak. These are high-risk thematic bets, not stable core holdings. Only invest money you can afford to lose.

Frequently Asked Questions
Is clean energy a good long-term investment?
The industry will likely grow, but that does not guarantee ETF returns. Many clean energy companies will fail while a few winners emerge. The winners are often already in the S&P 500 (NextEra, Tesla). A dedicated clean energy ETF concentrates you in the riskiest part of the sector.
Why did clean energy ETFs crash after 2021?
Rising interest rates (which increase borrowing costs for capital-intensive companies), supply chain disruptions, unprofitable business models catching up, and the 2020-2021 prices being fueled by speculative hype rather than earnings. Many holdings trade below their IPO prices.
ICLN or TAN — which is less risky?
ICLN is more diversified across solar, wind, hydrogen, and other clean technologies. TAN is concentrated in solar, making it more volatile. Neither is low-risk. If you must choose, ICLN's broader base offers slightly more protection against any single sub-sector collapsing.
