Green energy isn’t just a buzzword in 2025—it’s fueling the next big investment boom. This week, a fresh surge in trading volume put five under-the-radar green energy stocks in the spotlight, according to the latest data from MarketBeat. If you’re seeking the next breakout sector, keep your eye on Darling Ingredients, Mercer International, Nuvve, NWTN, and Richardson Electronics.

From bio-nutrient innovation to EV supercars, these companies are transforming how the world powers up. Investors are fueling billions into renewable energy stocks as governments double down on carbon reduction goals and new cleantech breakthroughs hit the market.

What Makes These Green Energy Stocks Stand Out in 2025?

Each company taps into a unique piece of the booming clean energy puzzle:

Darling Ingredients (NYSE: DAR): The global leader in transforming bio-nutrients into energy, feed, and food ingredients is making moves in the $4.87 billion sustainable materials market. With a diverse range of customers from the bioenergy to pharmaceutical sectors, Darling’s robust operating stats—like a 1-year low of $26 and high of $43.49—signal resilience and growth.
Mercer International (NASDAQ: MERC): This pulp and solid wood manufacturer’s aggressive push into renewables and clean electricity marks it as one to watch. Despite volatility, its market cap remains at $244 million with strong liquidity ratios—hinting at a turnaround.
Nuvve (NASDAQ: NVVE): Nuvve’s cutting-edge vehicle-to-grid (V2G) platform can turn every parked EV into a mini power station. With a beta of 2.13, it’s a volatile but potentially game-changing bet for grid stability and energy trading.
NWTN (NASDAQ: NWTN): Electric vehicle disruptors like NWTN are designing ‘smart’ passenger vehicles from the UAE to China, focusing on sustainable transport and in-car tech. Their strong price momentum signals growing investor confidence amid the global EV boom.
Richardson Electronics (NASDAQ: RELL): Richardson powers both medical tech and industrial energy transfer with radio frequency and microwave solutions—a critical backbone for the electrification wave and AI-driven manufacturing.

Q&A: How Can Investors Capitalize on Green Energy Trends?

Q: Why is green energy outperforming in 2025?
A: Surging government mandates, massive R&D investments, and widespread grid modernization efforts are fueling demand for renewable stocks. Clean energy is now considered both a defensive and a growth sector.

Q: Are these stocks risky?
A: Volatility in emerging sectors is normal, as seen by Nuvve and NWTN’s wide trading ranges. However, robust liquidity and global tailwinds give long-term investors a potential advantage if they select market leaders.

Q: Which other sectors benefit from this trend?
A: Battery storage, EV charging infrastructure, and supply chain companies (such as those found on Tesla and Ford) stand to gain as clean energy adoption accelerates.
