Two major clean energy exchange-traded funds posted outsized gains over the past year, yet they exhibit starkly different risk profiles. The SPDR S&P Kensho Clean Power ETF (CNRG) has returned 22.13% year-to-date and 91.23% over twelve months by focusing on regulated utilities and electricity generators, while the Invesco WilderHill Clean Energy ETF (PBW) surged 34.64% year-to-date and 129.89% over the same period, driven by a broader bet on electric vehicle makers, battery developers, and hydrogen companies. Crucially, during the last market downturn, PBW fell 61% while CNRG lost only 23%, highlighting the defensive versus growth trade-off these strategies entail.
Live News
- Performance divergence: PBW has nearly tripled investor capital over the past year (129.89%), while CNRG roughly doubled it (91.23%). Year-to-date, PBW leads by about 12.5 percentage points.
- Contrasting sector exposures: PBW invests in small-cap growth companies across EVs, battery storage, and hydrogen. CNRG focuses on large-cap utilities and electricity generators with stable, regulated revenues.
- Risk asymmetry: PBW lost 61% in the last downturn versus CNRG’s 23% decline, reflecting the higher volatility inherent in growth-focused clean energy names.
- Market environment sensitivity: PBW tends to outperform when investor risk appetite is high, while CNRG could provide relative resilience in rising-rate or recessionary scenarios.
- Investor implications: The two ETFs offer distinct tools for expressing a bullish view on clean energy—CNRG for capital preservation and PBW for aggressive growth—and their historical drawdowns illustrate the trade-off involved.

Key Highlights
The clean energy ETF landscape reveals a clear performance divergence this year, with the Invesco WilderHill Clean Energy ETF (PBW) outperforming its more conservative counterpart, the SPDR S&P Kensho Clean Power ETF (CNRG), by a wide margin in terms of year-to-date returns. However, the same volatility that fuels PBW's upside also amplified its losses during the most recent downturn.
According to data reviewed this week, PBW’s total return over the trailing twelve months reached 129.89%, compared with 91.23% for CNRG. The gap in year-to-date performance is also substantial: PBW rose 34.64% while CNRG gained 22.13%. These figures reflect the funds’ fundamentally different investment approaches.
PBW holds a portfolio that spans the broader clean energy value chain, including small-cap growth names such as electric vehicle manufacturers, battery technology firms, and hydrogen-related companies. This exposure tends to magnify gains in “risk-on” market environments. CNRG, by contrast, concentrates on utilities and power generators—businesses with regulated cash flows that typically provide more stable returns and may hold up better when interest rates spike or recession fears resurface.
The historical drawdown data underscores this contrast. In the last significant market correction, PBW experienced a peak-to-trough decline of approximately 61%, while the more defensive CNRG fell by about 23%. This suggests that investors choosing between the two must weigh the higher upside potential of PBW against the greater downside protection offered by CNRG.

Expert Insights
Professional observers note that the choice between CNRG and PBW may depend on an investor’s outlook for interest rates, economic growth, and the broader clean energy policy landscape.
CNRG’s focus on regulated utilities provides a cash flow stream that is less sensitive to economic cycles. Utilities typically benefit from a flight to safety during market turbulence and can even outperform when interest rates rise, as their earnings are often tied to allowed returns on rate base. This defensive characteristic likely explains CNRG’s relatively modest 23% drawdown during the last downturn.
Conversely, PBW’s tilt toward early-stage clean energy technologies makes it a higher-beta play. Many of its holdings are unprofitable or carry high valuations, which can amplify both gains and losses. In risk-on phases—such as the current environment, where investor optimism about clean energy adoption is elevated—PBW could continue to deliver outsized returns. However, any shift in macroeconomic conditions, such as a tightening of monetary policy or a slowdown in EV demand, could lead to sharper corrections, as seen in the fund’s 61% peak-to-trough decline.
Analysts caution that past performance, while illuminating, does not guarantee future results. The clean energy sector remains heavily influenced by government subsidies, technological breakthroughs, and commodity prices. Investors considering either ETF should align their choice with their risk tolerance and time horizon, keeping in mind that the defensive stability of CNRG may come at the cost of lower growth potential, while PBW offers higher upside alongside greater vulnerability to market downturns.
