It was supposed to be a poor year for the clean energy sector in 2025. Rising interest rates and stubborn inflation were driving up equipment and parts costs, and the One Big Beautiful Bill Act (OBBBA) eliminated many federal subsidies for solar and wind energy projects.

But despite facing headwinds from multiple directions, the clean energy sector thrived in 2025, and solar stocks were among some of the biggest winners.

The clean energy rally isn't slowing in 2026 either, as AI data centers continue to demand increasing power.

Today, we'll look at five booming clean energy stocks with more upside ahead.

Clearway Energy Group

Clearway Energy Group (NYSE:CWEN) is a diversified clean energy company with a portfolio of assets spanning geothermal, wind, solar, and hydroelectric facilities. A diversified set of operations helps protect the company from regulatory headwinds and provides versatility in partnering with a wide range of clients.

AI hyperscalers are beginning to take notice of the company's capabilities, as Google recently signed a $2.4 billion agreement with Clearway for 1.17 gigawatts of energy across three facilities. The stock is up more than 50% in the last 12 months, but it also has defensive characteristics, including a 4.5% dividend yield and a history of consistent raises since the payout was instituted in 2019.

Clearway is generally considered an income play due to its high payout and predictable revenue, but the stock's upward momentum has considerable strength as well. A brief pullback ended in January, when the stock crossed above the 50-day simple moving average (SMA) and the Moving Average Convergence Divergence (MACD) indicator had a bullish crossover.

With strong upward momentum and a healthy dividend, Clearway provides the best of both worlds right now, but investors will need to keep an eye on the Relative Strength Index (RSI) now that it’s above the Overbought threshold of 70. Plus, there's a catalyst on the horizon when the company reports Q4 2025 earnings on February 23.

NextPower Inc.

NextPower Inc. (NASDAQ:NXT) has defied regulatory and market headwinds to become a dominant force in the solar industry. Formerly known as Nextracker, the company designs and sells solar tracking systems that enable panels to track the sun’s path, similar to a sunflower. NextPower has turned into an earnings juggernaut, beating revenue and EPS estimates in every quarter for the last three years. In its most recent earnings report on January 29, the company reported $909 million in quarterly revenue (34% year-over-year growth) and a $5 billion backlog, while raising 2026 revenue guidance to $3.5 billion.

NextPower also announced $350 million in share buybacks, prompting several analysts to raise their price targets following a series of positive developments. UBS raised its price target to a Street-high $140, representing more than 20% upside from the current market price.

NXT shares soared more than 120% in 2025, but the rally stalled at the end of the year when shares dipped back below the 50-day SMA. This proved to be a bear trap however, and the stock resumed its uptrend as January began and is now up another 30% so far in 2026. Another consolidation pattern has emerged: the bullish wedge, which tends to end with an upside move. With the RSI back under the Overbought threshold, there's plenty of room for more upward momentum.

Bloom Energy Corp.

Bloom Energy (NYSE:BE) was a breakout star of the energy sector in 2025, soaring nearly 500% in a single year. The momentum appeared to continue into 2026 following an impressive earnings report last week, with record quarterly revenue of over $777 million.

The company's fuel cell systems have become critical in the AI industry's data center buildup, and its backlog now exceeds $20 billion. Oracle and Brookfield Asset Management have entered into agreements with Bloom, and management increased 2026 guidance to $3.3 billion following its Q4 2025 report.

BE shares fell by more than 10% on Thursday, which could present a buying opportunity for new investors. Since there was no company-specific news driving the decline, it can likely be blamed on profit-taking investors exiting positions during a turbulent market. The stock price is once again approaching the 50-day SMA, which served as a support level last year. The RSI has also returned to a normal level, so any resumption of bullish momentum will likely have underlying strength.

Ormat Technologies Inc.

Ormat Technologies (NYSE:ORA) is another geothermal energy play, and its technology is also crucial to data center buildout. Geothermal power systems have become integral to the 24/7 carbon-free electricity generation needs of AI hyperscalers and have helped the company post a record revenue of $249 million in Q3 2025. The company reports its Q4 2025 results on February 25, and analysts are projecting another record quarter of over $257 million.

The stock struck a new all-time high on February 3, finally surpassing the previous high set back in 2021. Following a brief stint in Overbought territory, the stock has pulled back to the 50-day SMA, which has been a sturdy support beam during the uptrend. With the RSI now back to normal levels, a bounce off the 50-day SMA becomes increasingly likely from here.

Shoals Technologies Group Inc.

Shoals Technologies (NASDAQ:SHLS) is a $1.6 billion market-cap company that develops electrical balance-of-system (EBOS) solutions for solar companies. EBOS is crucial to supplying the inverter with electrical current from the solar panels, and the company reported record quarterly revenue of $135 million in Q3 2025 (33% YOY growth), its highest quarterly revenue figure since 2023. Guidance for Q4 was $144 million, bringing the full-year total projection to $461 million.

Despite the revenue beat, the stock dropped nearly 20% following the report, falling below the 50-day SMA for the first time since August. SHLS shares have slowly clawed back these gains, and the 50-day SMA could once again act as support. The next catalyst is the Q4 2025 earnings release on February 24, and the stock is likely to trade in a tight range until then, which offers opportunities for new investors to build positions.
