With climate change accelerating and calls for corporations to adopt more sustainable practices growing louder, interest in renewable energy has soared. Wind, solar, hydroelectric, geothermal, and other carbon-free energy sources are expanding rapidly as costs fall and competitiveness rises.
Savvy investors seeking to profit from the clean energy boom now have a convenient option through renewable energy exchange-traded funds (ETFs).
Renewable energy ETFs bundle together stocks from across the renewable sector into a single fund for easy diversification. Rather than picking individual companies, investors can gain exposure to the full range of solar, wind, hydro, geothermal, biofuels, and more through these ETFs tracking related indexes.
Some of the largest investment firms like BlackRock, Vanguard, and State Street offer popular renewable energy ETFs. Global investments into renewable energy surpassed $1.8 trillion in 2023 alone. But what exactly are these ETFs, and what should interested investors consider before buying in?
This article will explore what renewable energy ETFs offer, key factors propelling their growth, risks, and considerations for investors, and provide examples of top funds to consider.
Given the immense worldwide growth projected for renewable energy, renewable energy ETFs present an appealing choice for investors seeking to benefit from the rapid clean energy transition in a diversified and values-aligned manner.
What Are Renewable Energy ETFs and What Do They Offer?
Renewable energy ETFs or exchange-traded funds, function much like traditional ETFs but with a focus on clean energy stocks. These funds bundle together holdings across solar, wind, hydroelectric, geothermal, biofuels, and more to offer investors exposure to the renewable energy sector.
Diversification Across Technologies and Companies
The key advantage of renewable energy ETFs is that they provide diversification across the range of renewable energy technologies and companies. Rather than betting on just one or two individual stocks, these funds allow you to invest in the sector as a whole.
For example, the Invesco Solar ETF (TAN) holds 22 solar energy stocks including panel manufacturers, installation firms, and semiconductor companies tied to solar.
- Top 5 holdings: Enphase Energy, SolarEdge Technologies, Sunrun, First Solar, Xinyi Solar
- Exposure across the solar supply chain
Other ETFs take an even broader approach, like the iShares Global Clean Energy ETF (ICLN) tracking an index of 30 clean energy-related companies worldwide.
Ease of Access
Renewable energy ETFs also make investing in the sector more accessible. You can conveniently trade them like stocks rather than directly researching and purchasing individual companies or projects.
These funds take care of selecting holdings and maintaining allocations to give a representative slice of the renewable energy market. Many brokerages allow commission-free trading of certain ETFs, further improving ease of access.
So for those excited by the potential of clean energy, renewable energy ETFs offer a simpler way to gain exposure by tapping into the growth and upside across technologies and companies. They provide the diversification and professional management benefits inherent to ETFs applied to the thriving renewable energy sector.
Key Factors Driving Growth in Renewable Energy ETFs
Several powerful trends are fueling rapid expansion in renewable energy ETFs. Understanding these growth drivers provides insight into the bullish outlook for these funds.
- Government Policies – Renewable energy policies are among the strongest catalysts. Renewable portfolio standards require utilities to source minimum amounts of power from renewables. Tax credits reduce project costs. Carbon pricing makes fossil fuels less competitive. Infrastructure bills allot billions to clean energy. These policies are enacted globally from the U.S. to China.
- Falling Technology Costs – The costs of solar panels, wind turbines, batteries, and other technologies continue to fall steadily, leading to higher adoption and competitiveness. For example, lithium-ion battery pack prices dropped 89% from 2010 to 2020. The software also unlocks performance gains for renewable assets.
- Cost Competitiveness – As technology costs decrease, renewable energy becomes increasingly cost-competitive with traditional fossil fuel plants. Unsubsidized levelized costs are now at or below fossil fuels. For instance, wind and solar PPA prices averaged 2-5 cents per kWh in 2021, competitive with natural gas plants.
- Corporate ESG Focus – Companies worldwide are allocating more capital towards environmental, social, and governance (ESG) principles. For many firms, increasing renewable energy usage and investments supports ESG-aligned growth.
- Energy Security – Renewables boost energy independence and security through domestic energy generation. This energy security has become increasingly important for nations aiming to insulate against global energy supply disruptions.
The powerful combination of supportive policies, competitive economics, ESG, and energy security concerns is accelerating capital inflows into renewable energy. This provides a robust backdrop supporting increased investment and growth of renewable energy ETFs.
Key Considerations and Risks When Investing in Renewable Energy ETFs
While the future looks bright, there are also important considerations and potential risks to consider when investing in renewable energy ETFs.
- Policy Dependence – The renewable energy sector relies heavily on government incentives and policies. Any reductions or changes, such as PTC phase-outs, can dampen growth prospects.
- Fossil Fuel Prices – Low natural gas prices may constrain competitiveness. Renewable energy stocks often have an inverse relationship with oil and gas prices.
- Economic Conditions – Recessions can lead to reduced energy demand. Clean energy funds may underperform broader markets in times of economic weakness.
- Volatility – Immature technologies see rapid change. Renewable energy stocks can be volatile with temporary supply/demand imbalances.
- Strategy Variation – Funds differ in approach, such as passive vs active, market capitalization focus, and geographic allocations.
- Underlying Index – Performance depends heavily on the index methodology. Weighting toward certain technologies like solar introduces concentration risks.
- Fees – Expense ratios vary between ETFs and can erode into long-term returns.
- Liquidity – Thinly traded funds can have high bid-ask spreads and trading costs.
As with any sector, risks exist alongside the potential rewards. However, renewable energy ETFs allow investors to mitigate risks through diversification across companies, regions, and technologies.
Some Leading Renewable Energy ETF Examples
A bias toward getting acquainted with the more established funds could be tempting, especially given the rapid proliferation of renewable energy ETF options over the last few years. It evaluates a few key offerings below to provide some helpful context ahead of diving in deeper.
Some of the original trailblazers that commenced in 2008 and are still around today include the Invesco Solar ETF (TAN), which now represents over $3 billion in assets under management, to provide concentrated solar exposure.
Its holdings read like a who’s who of the solar industry, with the top panel manufacturers, installers, semiconductor suppliers, and more represented among them. It’s among the top few gainers for the trailing five years—a period during which solar witnessed a surge in adoption.
Meanwhile, the iShares Global Clean Energy ETF (ICLN) offers diversified exposure to a number of renewable sources. ICLN, one of the best in the sector with over $4 billion in assets under management, includes firms dealing with wind, solar, biofuel, and hydrogen besides clean energy companies from up-and-coming to developed markets.
That gives a worldwide view to investors on the incursion of renewables into the ETF scene.
Alternatively, for investors who prefer bets that are more targeted in nature, the SPDR S&P Kensho Clean Power ETF (CNRG) comes to the fore. CNRG is the first-of-its-kind methodology for domestic clean energy exposure with its AI-powered index.
Much smaller in assets under management, CNRG provides a laser-focused way for those seeking targeted exposure to American renewable leaders across proven technologies.
These are only the highlighted ETFs, but there are many others available. These renewable energy ETFs vary greatly, from broad global funds to very specialized. Each investor is unique in their goals and tolerance for risk.
Regarding renewable energy ETFs, an overview and sampling of these offerings will likely help people find a match for their sustainability values and investing targets. Risks remain, of course, and the upward path of renewable power suggests openings for investors who do homework and have long-term convictions.
