Renewable ETFs vs. Traditional ETFs: Which Should You Invest In for 2025 and Beyond?

The race toward clean energy isn’t just transforming the way the world powers its homes, cars, and cities—it’s also reshaping investment strategies. As the renewable energy sector grows rapidly, more investors are considering renewable energy ETFs as a way to align their portfolios with both financial growth potential and environmental values. But how do these funds compare to traditional ETFs that track broad market indexes like the S&P 500 or the total U.S. stock market?

In this comprehensive guide, we’ll break down what renewable ETFs are, how they stack up against traditional ETFs in performance, risk, costs, and diversification, and—most importantly—which option might be right for your investment goals. You’ll get real-world data, expert insights, and actionable takeaways to help make an informed decision.

1. Understanding ETFs: The Basics

What Is an ETF?

An Exchange-Traded Fund (ETF) is a basket of securities—stocks, bonds, or other assets—that trades on an exchange like a stock. ETFs are popular for their diversification, low costs, and liquidity.

Two Main Types for Our Comparison

  1. Renewable Energy ETFs are funds that invest specifically in companies in the clean and renewable energy sectors.
  2. Traditional ETFs—Broad-market funds that track large indexes like the S&P 500 (SPY) or Vanguard Total Stock Market (VTI).

Why it matters: Knowing the difference helps you align your portfolio with your risk tolerance, ethical values, and return expectations.

2. What Are Renewable Energy ETFs?

Definition: Renewable energy ETFs focus on companies producing power from sustainable sources—solar, wind, hydropower, bioenergy, and increasingly, electric vehicle (EV) infrastructure.

4. Performance Comparison: Renewable vs. Traditional ETFs

Over the last decade, renewable ETFs have shown periods of outperformance but also sharp pullbacks.

Historical Performance Snapshot

Fund3-Year Avg Return5-Year Avg Return10-Year Avg Return
ICLN~30%~13.5%~13.5%
TAN~28%~12.8%~12.4%
VTI~11%~11.5%~11.8%
SPY~10.9%~11.6%~11.9%

Key Insights:

  • Renewable ETFs can outperform traditional ETFs in bull markets for clean energy.
  • They tend to be more volatile, with larger drawdowns during downturns.
  • Traditional ETFs have delivered steady and predictable growth over decades.

5. Risk & Volatility Factors

Renewable ETF Risks:

  • Policy changes (e.g., government subsidies or carbon tax laws)
  • Technological disruptions (battery breakthroughs, grid limitations)
  • Commodity price swings (e.g., lithium for batteries)

Traditional ETF Risks:

  • Broader market downturns (recessions, inflation spikes)
  • Sector-specific downturns in dominant industries like tech or finance

Beta Values: Many renewable ETFs have a beta of 1.2–1.5, meaning they’re 20–50% more volatile than the broader market.

6. Cost & Expense Ratio Analysis

Why It Matters: Even small differences in expense ratios can compound significantly over decades.

  • Renewable ETFs: Typically 0.41–0.75%
  • Traditional ETFs: Often 0.03–0.09%

Example:
A $10,000 investment over 20 years earning 8% annually:

  • With 0.05% expense ratio → ~$46,610
  • With 0.70% expense ratio → ~$42,479
    That’s over $4,000 lost to fees.

7. ESG & Ethical Investing Angle

More investors are choosing investments that reflect their values. ESG investing has grown into a multi-trillion-dollar industry.

Renewable ETFs’ ESG Advantage:

  • Direct exposure to companies driving the clean energy transition
  • Appeal to climate-conscious investors
  • Increasing inflows after major climate policy announcements (e.g., U.S. Inflation Reduction Act)

Traditional ETFs and ESG:

  • Some broad-market ETFs are adding ESG-screened variants (e.g., ESGV from Vanguard).
  • Still include fossil fuel companies unless explicitly excluded.

8. Which ETF Type Is Right for You?

Choose Renewable ETFs if:

  • You have a long-term growth horizon (10+ years).
  • You can tolerate higher volatility.
  • You value sustainability and ESG investing.

Choose traditional ETFs if:

  • You prefer lower fees and stable growth.
  • You want broad diversification.
  • You have a lower risk tolerance.

Balanced Approach:
Many investors choose a core-satellite strategy:

  • Core: 70–80% in traditional ETFs for stability
  • Satellite: 20–30% in renewable ETFs for growth.
