Introduction – Why Clean Energy Stocks?

Development, innovation, interest, and investment in clean energy has been on the rise with fossil fuels [hopefully] on the way out. Increasing energy demands from emerging markets around the globe will expedite the transition. Moreover, state and federal subsidies and tax credits will continue to accelerate the adoption of green energy initiatives as concerns over climate change mount, and the Biden administration is urging more action be taken specifically in the U.S.

Think solar, wind, hydroelectric, geothermal, etc., as well as the tech that services those specific resources. Things like solar panel installations and electric vehicle sales are at record highs. Diversification is important in investing in clean energy due to the fact that some of the underlying companies can easily go under. Below are the best clean energy ETFs to access diversified exposure to the market segment, both domestically and globally. Demand for and investment in clean energy ETFs have surged in recent years, with investors betting that the U.S. will begin taking things more seriously when it comes to climate change.

The 9 Best Clean Energy ETFs

Below are the 9 best clean energy ETFs, which vary in size, scope, and cost:

ICLN – iShares Global Clean Energy ETF

The iShares Global Clean Energy ETF (ICLN) is the most popular ETF in this space, with over $1.3 billion in assets. It’s also the oldest; it started in 2008. This fund provides broad, global exposure to the clean energy market segment with 31 companies involved in wind, solar, hyrdroelectric, and other alternative energy sources, as well as companies that provide clean energy tech.

The fund is well-diversified globally, with significant holdings in Canada, New Zealand, Hong Kong, Brazil, and more, with only about 40% in the United States. Its largest exposures are renewable energy equipment and services, electric utilities, and power producers. The fund seeks to track the S&P Global Clean Energy Index and has an expense ratio of 0.46%.

PBW – Invesco WilderHill Clean Energy ETF

The Invesco WilderHill Clean Energy ETF (PBW) is another popular broad clean energy ETF, with comparatively more of a tech, industrial, and manufacturing focus than ICLN above, with less exposure to pure energy plays like utilities and power producers. PBW also seems to put a bit more weight on solar. Note too that PBW heavily tilts small cap.

While this fund’s sector exposure can be considered broader than ICLN, PBW’s geographic exposure is less diverse, with its holdings almost entirely in the United States (86%) and China (9%). The fund was established in 2005 and seeks to track the WilderHill Clean Energy Index. This ETF has 42 holdings, nearly $2 billion in assets, and an expense ratio of 0.70%.

PBD – Invesco Global Clean Energy ETF

Whereas PBW above is mostly U.S. companies, PBD specifically aims to diversify globally. PBD is slightly newer than PBW. It launched in 2007 and has amassed roughly $500 million in assets. While they differ by one letter, PBW and PBD only have about 30% overlap by weight.

PBD is basically actively managed in that it looks for companies with high expected growth. Components are equally weighted and are spread across a variety of companies linked to conservation and the advancement of clean energy, not just energy producers. While a fund like ICLN is market cap weighted and thus concentrated in a handful of stocks, PBD’s equal weighting scheme allows it to avoid concentration.

This fund seeks to track the Wilderhill New Energy Global Innovation Index, has 132 holdings, and has an expense ratio of 0.75%.

QCLN – First Trust NASDAQ Clean Edge Green Energy Index Fund

The First Trust NASDAQ Clean Edge Green Energy Index Fund (QCLN) seeks to track the NASDAQ Clean Edge Green Energy Index. This ETF is even more tech-focused than PBW and PBD above, investing in manufacturers, developers, distributors, and installers of materials, energy tech, energy storage and conversion, or renewable electricity production.

QCLN’s holdings are larger than the other funds on this list, but they’re still mostly mid caps.

The fund has 43 holdings and an expense ratio of 0.60%.

SMOG – VanEck Vectors Low Carbon Energy ETF

SMOG launched in 2007 and seeks to track the SMOG-US – MVIS Global Low Carbon Energy Index. This ETF was previously GEX.

This fund holds companies around the globe with at least half of their revenue coming from wind, solar, geothermal, hydro, hydrogen, waste, and biofuels. It also includes companies related to electric vehicles, air purification, and battery tech.

Like PBD, SMOG is not concentrated in the U.S. (the U.S. comprises about 30% of the fund), but its market cap weighting means its holdings are concentrated in a few names like Tesla (9%) and NextEra (8%).

SMOG has 70 holdings and an expense ratio of 0.70%.

ERTH – Invesco MSCI Sustainable Future ETF

First, note that this fund used to be called the Invesco Cleantech ETF, and its ticker used to be PZD.

ERTH is pretty similar to SMOG above – companies around the globe with at least 50% of their revenues coming from these 6 “Environmental Impact” themes: alternative energy, energy efficiency, green building, sustainable water, pollution prevention and control, and sustainable agriculture. Even the geographical allocations are similar.

ERTH also employs some ESG screens, excluding companies with recent ESG controversies and companies and companies involved in weapons. 

ERTH seeks to track the MSCI Global Environment Select Index. It has about $425 million in assets, 234 holdings, and an expense ratio of 0.58%.

CTEC – Global X CleanTech ETF

CTEC focuses specifically on clean technology. It holds companies from around the world that develop technologies or equipment related to renewable energy production, energy efficiency and storage, smart grid implementation, lithium-ion batteries and/or fuel cells, or preventing pollution.

The fund is market cap weighted, but individual holdings are capped at 6%. CTEC launched in late 2020 but has already accumulated over $150 million in assets. The fund has 40 holdings and an expense ratio of 0.50%.

FAN – First Trust Global Wind Energy ETF

Interested in specifically targeting wind energy? The First Trust Global Wind Energy ETF (FAN) is the only ETF to provide narrow exposure to wind energy.

While often forgotten and less flashy, wind power is considered a crucial piece of green energy initiatives. Many places around the world with low sunlight get a significant portion of their energy from wind. Companies in this fund must be actively engaged in the wind energy industry in some way, such as the development of a wind farm, or the distribution of wind-generated electricity.

The U.S. is just getting started with wind energy, so currently the fund is mostly made up of companies outside the United States. Investors may enjoy this fact, betting that the U.S. will accelerate its wind energy efforts in the near future, which would be good news for this fund.

While this fund provides very targeted exposure to a single type of clean energy, that exposure is well-diversified in 47 holdings across the globe. FAN seeks to track the ISE Global Wind Energy Index and has an expense ratio of 0.62%.

ACES – ALPS Clean Energy ETF

The ALPS Clean Energy ETF (ACES) seeks to track the CIBC Atlas Clean Energy Index, a market-cap-weighted index providing exposure to the clean energy sector in North America. ACES takes somewhat of a broader approach to clean energy, including things like LED technology and hydrogen fuel cells.

The fund has 33 holdings across the United States (75%) and Canada (25%). It has an expense ratio of 0.65%.

Where to Buy These Clean Energy ETFs

All these ETFs should be available at any major broker. My choice is M1 Finance for U.S. investors. The broker has zero trade commissions and zero account fees, and offers fractional shares, dynamic rebalancing, and a modern, user-friendly interface and mobile app. I wrote a comprehensive review of M1 Finance here.

Canadians can find the above ETFs on Questrade or Interactive Brokers. Investors outside North America can use eToro or possibly Interactive Brokers.
