Exchange-traded funds (ETFs) have become popular in North America in a wide range of industries, including the clean energy sector, whose appeal is rapidly increasing.
For investors looking to gain exposure to the cleantech market, investing in individual stocks can be daunting considering the broad reach of this market sector.
The cleantech umbrella covers a range of sectors, including renewable energy technologies, such as wind and solar; battery technologies for electric vehicles and large-scale energy storage systems; agritech, water treatment and air purification systems; built environment technologies; carbon capture, biofuels and green hydrogen.
ETFs have become so popular partially because they provide a safer way for investors to gain exposure to various industries while avoiding the volatility that comes with investing in individual stocks, making ETFs a good fit for investors looking for exposure to the cleantech sector’s many options.
Below is a look at the five top clean energy ETFs to consider, ranked by total assets under management. All numbers and figures were gathered using ETFdb.com and were current as of January 13, 2026. Read on to learn about the options available to investors.

An analyst report on the ETF states that it ‘likely doesn’t deserve’ a large weighting in an investor’s long-term portfolio. It suggests that the fund could instead be useful as a satellite holding that looks at a fraction of the market that is often overlooked by less focused ETFs.
The iShares Global Clean Energy ETF has 103 holdings. Three of its top-weighted holdings are Bloom Energy (NYSE:BE), First Solar (NASDAQ:FSLR) and Sunrun (NASDAQ:RUN). In terms of performance, this ETF has a one year return rate of 59.37 percent.
