3 Renewable Energy Stocks Investors Are Watching for Explosive Growth in 2026
Published · Updated · 4 min read
A new report from Zacks Investment Research says three renewable energy companies could see strong growth in 2026. The growth is driven by rising demand for wind, solar, hydrogen, and clean power as countries and companies move away from fossil fuels.
Zacks projects that renewable energy will pass coal as a top global power source by 2026. Renewables are expected to make up about 36% of global electricity, while coal falls to around 32%. This shift is being powered by new clean energy projects, better technology, and higher electricity use from data centers, electric vehicles, and AI systems.
The report highlights three companies investors are closely watching: Canadian Solar, FuelCell Energy, and NextEra Energy.
1. Canadian Solar (CSIQ) — Solar Power Soars
Canadian Solar is one of the world’s largest makers of solar panels and energy storage systems.
According to Zacks estimates:
- Revenue could rise about 35% in 2026
- Earnings could jump nearly 78% year over year
- The company expects to ship 25–30 gigawatts (GW) of solar panels in 2026
- Around 1 GW will be used for its own solar projects
Demand for solar panels is growing fast as governments and utilities invest in large solar farms and battery storage to replace coal and gas power plants.
Why it matters: Solar energy is one of the cheapest ways to produce electricity today. As more countries set clean energy targets, companies like Canadian Solar are well positioned to benefit from long-term global demand.
Risks: CSIQ stock can be volatile. Prices may move with solar panel costs, global trade rules, and supply chain issues.
2. FuelCell Energy (FCEL) — Hydrogen and Backup Power
FuelCell Energy builds carbon-free power systems that use hydrogen and fuel cell technology to produce electricity.
Zacks projects:
- Revenue growth of about 22% in 2026
- Earnings growth close to 59%
The company has a strong project backlog, including work in South Korea. FuelCell Energy is also targeting AI data centers, which need reliable power around the clock.
Government incentives and company climate goals are helping fuel cell systems gain interest as on-site clean power solutions.
Market reaction: Recent earnings reports showed revenue growth and smaller losses, which helped lift the stock as investors became more optimistic.
Why it matters: Fuel cells provide steady electricity with low emissions. They work well alongside wind and solar, which can vary with weather. This makes them useful for data centers, factories, and microgrids.
3. NextEra Energy (NEE) — Renewable Utility Giant
NextEra Energy is one of the largest utility companies in the U.S. and a major leader in renewable power.
The company produces electricity from:
- Wind
- Solar
- Battery storage
- Natural gas
Zacks says revenue and earnings should continue to grow in 2026, though at a slower pace than the other two stocks.
NextEra plans to add 36.5 GW to 46.5 GW of new renewable capacity between 2024 and 2027.
Why it matters: NextEra is often called a “sleep-well-at-night” stock. It offers steady utility income while also investing heavily in clean energy growth.
Market notes: The stock trades at a premium valuation, showing strong investor confidence in its long-term strategy.
Why 2026 Could Be a Big Year for Renewables
Several trends support strong growth in clean energy:
- Solar and wind capacity is expanding faster than older power sources
- Technology costs are falling, making renewables cheaper
- Electric vehicles, AI, and cloud computing are driving higher power demand
- Governments continue to support clean energy through policies and incentives
Because of these trends, many investors see renewable stocks as long-term opportunities, not short-term trades.
Quick Comparison Table
| Company | Focus | 2026 Growth Outlook (Zacks) | Key Strength |
| Canadian Solar (CSIQ) | Solar panels & storage | Revenue ~+35%, Earnings ~+78% | Strong global solar demand |
| FuelCell Energy (FCEL) | Fuel cells & hydrogen power | Revenue ~+22%, Earnings ~+59% | Clean power for AI & industry |
| NextEra Energy (NEE) | Wind, solar & utilities | Moderate growth | Large, stable renewable platform |
Investor Risks and Cautions
Renewable energy investing still carries risks:
- Volatility: Prices can swing with interest rates and policy changes
- Regulation: Tax credits and incentives may change with elections
- Supply chains: Trade issues and materials costs can impact profits
Investors should always consider personal goals and risk tolerance before investing.
Bottom Line
According to Zacks Investment Research, Canadian Solar, FuelCell Energy, and NextEra Energy stand out as renewable energy stocks with strong potential growth in 2026. Together, they cover solar manufacturing, fuel cell technology, and large-scale renewable utilities.
As Nasdaq notes, renewable energy is no longer just about climate goals. It is reshaping global power markets, investment flows, and the future of electricity, making these stocks important names to watch in the coming years.
