Experts agree that climate change is one of the greatest concerns of our time. Fossil fuels are a major contributor to climate change, and one industry that relies heavily on fossil fuels is energy production.
Clean energy technologies will be one of the best ways to fight climate change going forward as they’ll allow people to burn less fuel while maintaining their current lifestyles. Clean energy exchange-traded funds (ETFs) give investors a way to add some of these new and emerging technologies to their portfolios.
We’ve built this list of the five best clean energy funds, listed in no particular order, by reviewing dozens of funds and examining factors like: expense ratio, assets under management (AUM), historical returns, and liquidity.

Pros and Cons of Investing in Clean Energy ETFs
- Invest in a growing sector
- Feel good about your investment choices
- Miss out on investing gains from fossil fuels
- Limited investment options
- Invest in a growing sector: Renewable energy and other clean energy technologies are the fastest-growing energy sources in the U.S. Their output doubled between 2000 and 2018 and is poised to continue growing. This gives investors an opportunity for significant gains as clean energy increases its market share.
- Feel good about your investment choices: Some investors like to put their money in investments that they feel support their personal beliefs and goals. If you want to help fight against climate change, investing in companies dedicated to clean energy can make you feel good.
- Miss out on fossil fuels: Fossil fuels, such as crude oil, still provide the majority of energy used in the United States, and these clean energy ETFs don’t hold any fossil fuel investments. People looking for broader exposure to U.S. energy companies will want to include some fossil fuel businesses in their portfolios.
- Limited investment options: Clean energy is a niche category in the energy industry, so there are fewer ETFs that focus on clean energy in particular as compared to energy as a whole. Limited investment options means that investors may struggle to find an ETF that fits their needs.
Historical Performance Trends
Over the past decades, clean energy has become a more important part of the U.S. economy, with renewable sources becoming a larger portion of its overall energy production. However, between April 2011 and July 2012, clean energy companies experienced a downturn with the S&P Global Clean Energy Index falling over 66%. After a few years of relatively steady prices, as of May 26, 2021, the index was up more than 250% from the lows of 2012.
With many people focused on climate change, renewable energy companies have the potential to become a more important part of energy production around the world. This, in turn, gives such businesses the potential to grow in the future.
While historical performance doesn’t guarantee future results, it can be useful to look at how some investments performed in the past to predict their future potential.
