5 Biggest Clean Energy ETFs in 2024

Total assets: US$2.477 billion

The iShares Global Clean Energy ETF was created on June 24, 2008, and has a large portfolio of domestic and international stocks.

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 be useful as a "satellite holding" that looks at a fraction of the market that is often overlooked by less focused ETFs.

Three of the iShares Global Clean Energy ETF's top-weighted holdings include: Enphase Energy (NASDAQ:ENPH) at 8.81 percent, First Solar (NASDAQ:FSLR) with a 7.64 percent weighting, and Nextracker (NASDAQ:NXT) at 4.93 percent.

Total assets: US$837.32 billion

The First Trust NASDAQ Clean Edge Green Energy Index Fund, which officially came into existence on February 14, 2007, is a "unique member" of the alternative energy category, according to ETFdb.com. Why? Because it invests in companies that have interests in different green energy subsectors, such as biofuels, solar energy and advanced batteries.

ETFdb.com also states that because of this ETF's focus, it may be appealing to investors looking for broader exposure in the alternative energy sector. Three of its highest-weighted holdings are ON Semiconductor (NASDAQ:ON) at 8.83 percent, First Solar at 7.75 percent, and Tesla (NASDAQ:TSLA) at 6.93 percent.

Total assets: US$366.32 million
