| 2 | FSLR | First Solar Inc | ~8.6% | |

| 9 | EDPR.LS | EDP Renovaveis | ~2.5% | |
| 10 | ED | Consolidated Edison | ~2.5% |
ICLN's portfolio mixes equipment makers, project developers, and regulated utilities. Top holdings include Bloom Energy near 14%, First Solar around 8.6%, NextEra Energy near 7%, China Yangtze Power around 6.3%, and Enphase Energy near 4.5%.
The fund is genuinely global, with large weights in European names like Iberdrola, Vestas Wind Systems, and Orsted, plus Chinese hydropower. That geographic spread diversifies single-country policy risk but adds currency exposure to the mix.
ICLN vs single-theme clean-energy funds
ICLN's main advantage over funds like the hydrogen ETF HYDR or a solar-only ETF is breadth. By holding about 100 companies across multiple clean-energy sub-sectors, it avoids the boom-or-bust concentration of a single-technology bet.
The trade-off is that ICLN will not capture the full upside of a niche that runs hot, since any one theme is diluted. Investors who want targeted exposure sometimes pair ICLN as a core clean-energy holding with a smaller single-theme satellite.
Performance and outlook
ICLN soared during the 2020 to 2021 clean-energy boom, then fell hard as interest rates rose and policy support became less certain. Its performance is closely tied to rate cycles, government incentives, and the economics of solar and wind projects.
The long-term case rests on the global energy transition, electrification, and continued cost declines in renewables. That trend is durable but cyclical, so ICLN can trade in wide ranges and requires patience through multi-year swings.
Is ICLN a good fit
Whether ICLN fits depends on your goals, risk tolerance, and time horizon, and Walnut is not an investment adviser. ICLN gives broad, liquid, global clean-energy exposure, but it is a cyclical single-sector fund, so it is usually held as a thematic satellite rather than a core position.
Investors who believe in the energy transition and can tolerate large swings may find ICLN a straightforward way to own the theme. Consider how much sector concentration and international exposure you are comfortable adding before you buy.
How to buy ICLN
ICLN trades on the Nasdaq and can be purchased in any standard brokerage account, including Robinhood, Fidelity, Schwab, and Public. Many of these brokers offer fractional shares, so you can add ICLN in small dollar amounts.
You can also connect your existing broker to Walnut to track ICLN alongside your other holdings and target weights, and see how a clean-energy sleeve fits your overall plan before adding to it.
The bottom line on ICLN
ICLN is the default core holding for broad, global clean-energy exposure at a reasonable 0.39%. It spreads risk across solar, wind, and utilities rather than betting on one niche. It remains cyclical and rate-sensitive, so most investors size it as a thematic satellite rather than a core position.

FAQ
What is ICLN?

+
ICLN is issued by iShares, the ETF arm of BlackRock, the world's largest asset manager. Launched in 2008, ICLN is one of the oldest and largest clean-energy ETFs and is widely used as the benchmark for the theme.
What is the difference between ICLN and a hydrogen ETF like HYDR?
+
ICLN is a broad, global clean-energy fund holding about 100 solar, wind, and utility companies. HYDR is a narrow pure-play hydrogen fund of about 25 names. ICLN spreads risk across the whole sector, while HYDR concentrates on one clean-energy niche and is far more volatile.
What does ICLN hold?
+
ICLN holds around 100 clean-energy companies globally. Top positions include Bloom Energy, First Solar, NextEra Energy, China Yangtze Power, and Enphase Energy, plus European names like Iberdrola, Vestas Wind Systems, and Orsted. It mixes equipment makers, developers, and utilities.
What is ICLN's expense ratio?
+
ICLN charges a 0.39% annual expense ratio, about $3.90 per year on a $1,000 position. That is reasonable for a global thematic fund and lower than most single-theme clean-energy ETFs, which often charge 0.50% or more.
Does ICLN pay a dividend?
+
ICLN pays a dividend, typically on a semi-annual schedule, with a yield that has run around 1.2%. Its utility and infrastructure holdings generate some income, but clean-energy growth companies pay little, so the overall yield is modest.
How do I buy ICLN?
+
ICLN trades on the Nasdaq and can be bought in any brokerage account, including Robinhood, Fidelity, Schwab, and Public. Many brokers support fractional shares. You can also connect your broker to Walnut to track ICLN alongside your other holdings and target weights.
How big is ICLN?
+
ICLN manages around $3 billion in assets as of mid-2026, making it the largest diversified clean-energy ETF. Its size gives it strong liquidity and tight bid-ask spreads, which lowers trading costs compared with smaller thematic funds.
Is ICLN a good investment?
+
That depends on your goals, risk tolerance, and time horizon, and Walnut is not an investment adviser. ICLN is a cyclical, rate-sensitive sector fund that can swing widely with policy and energy prices. Consider how a clean-energy sleeve fits your overall plan before buying.
When was ICLN created?
+
ICLN launched in June 2008, making it one of the earliest clean-energy ETFs. It expanded significantly during the 2020 to 2021 clean-energy boom and later broadened its index to hold roughly 100 companies rather than a narrower 30.
What index does ICLN track?
+
ICLN tracks the S&P Global Clean Energy Index, which includes companies in solar, wind, hydrogen, and clean utilities across developed and emerging markets. The index was broadened in 2021 to reduce concentration and improve liquidity.
Why is ICLN so volatile?
+
Clean energy is capital-intensive and sensitive to interest rates, subsidies, and energy prices. When rates rise or policy support wavers, the sector can fall sharply. ICLN's global scope diversifies single-name risk but does not remove the sector's cyclicality.
Is ICLN a global or US fund?
+
ICLN is global. It holds clean-energy companies from the US, Europe, China, and other markets, so it carries currency and international exposure. That gives broader reach than a US-only clean-energy fund but adds foreign-market risk.
How do I compare ICLN to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. ICLN's figures are above; the full method is in Walnut's guide on how to compare ETFs.
