So what clean energy penny stocks should you have your eyes on this month?
The stocks we’ll focus on today are defined by the SEC as stocks traded for under $5. Some investors only consider stocks trading at under $1 to be penny stocks. While clean energy penny stocks themselves are notorious for their low fluctuations on the stock market, we can still take a look at some companies and penny stocks to buy that are more than ready for a big breakout.
5 Best Penny Stocks To Watch In This Sector
Here are some very inexpensive energy penny stocks in green energy businesses and clean energy stocks to watch around the world.
1. Ocean Power Technologies, Inc.
Ocean Power Technologies commercializes proprietary systems that create electricity. As their name suggests, they primarily harness energy from the kinetic power of the ocean’s waves. The company has multiple segments which are broken down along geographical lines. There are segments for North America, Europe, Asia, and Australia.
Hovering around $4.80 per share, Ocean Power Technologies’ stock is one of the hot energy penny stocks on our radar.
Overall market sentiment has been high on OPTT stock lately. It receives a Bullish rating from InvestorsObserver's Stock Sentiment Indicator.
One of the things that potentially make OPTT stock one to watch is its position in the renewables market. Joe Biden's presidency has a large goal of moving the United States toward sustainable power within the next decade or so. With that in mind, it could be that companies like Ocean Power will grow in popularity.
This exciting alternative energy company acquired 3Dent Technology, an offshore alternative energy engineering and design services company based in Houston, Texas just a few weeks ago. 3Dent’s services expand OPT’s ability to provide comprehensive solutions to customers operating in offshore wind and offshore oil and gas.

Wafer

Solar Power Projects
So should you buy this energy penny stock? Believe it or not, ReneSola Ltd is up a whopping 107.44% year to date.
The Chinese clean power company is currently on an upward trajectory at about $23.60 per share. The products and services they provide are increasing in demand worldwide. I like what we’re seeing with Rene Sola Ltd lately, so I’d definitely keep this in your penny stocks to watch list.

3. Clean Energy Fuels Corp
Don’t sleep on this penny stock to watch. Just last year (March 2nd 2020) the corporation was trading at $2.16 on the stock chart, and since then it’s grown to $13 a share. California-based Clean Energy Fuels Corp (CLNE on the NYSE) provides clean gas and alternative fuels for vehicle fleets in North America. They’re one of my favorite green energy penny stocks at the moment. The company also builds and manages compressed natural gas (CNG) and liquified natural gas (LNG) fueling stations.
On February 8th, the clean energy company announced that the Los Angeles County Metropolitan Transportation Authority (Metro) has signed a new agreement for an estimated 47.5 million gallons of its renewable gas (RNG) to fuel the nation’s largest transit bus fleet.
This agreement will mark the completion of Metro’s 5-year goal to transition its diesel fleet to cleaner, low-carbon fuel, with 2,400 buses now running on RNG—the first renewable and commercially available vehicle fuel made entirely from organic waste. This and a few other recent deals have seen the company’s stock shoot up by over 37% following the breaking news
It’s one of those alternative energy penny stocks that you need to keep your eyes on (or better yet take a look at investing)
CLNE also recently announced a partnership with Chevron to help Chevron produce renewable natural gas. This and a few other recent deals have seen the company’s stock shoot up by over 20% following the breaking news. The stock is still trading at $17.74 on the stock chart and is one of the hottest environment friendly penny stocks to watch. We have a strong buy rating on this clean energy penny stock based on a promising outlook for the future.

4. Urja Global
This Indian clean energy sector company is one of those green energy penny stocks that has attracted a wealth of new investors in a brief span of time. It is one of the younger companies on our list, so now is a good time to get an early start and buy their shares before Wall Street catches on.
Urja Global recently gained several new contracts for Solar PV module installation projects in several states. It's still a younger and thus riskier penny stock to watch, but still certainly worth keeping tabs on. It’s also very inexpensive at just $7.90 per share on the stock chart. It’s an exciting penny stock to watch.
5. Yingli Green Energy Holdings Ltd.
Lastly, we have Yingli Green Energy Holdings Ltd. The $0.98 share on the stock chart is one of many Chinese green energy penny stocks although it’s one of the cheaper ones you’ll find for a Chinese solar panel manufacturer. Yingli’s estimated annual revenue last year was $700m USD.
According to a report published on Bloomberg, the Crystalline silicon solar PV modules Market to grow by $46.90 in 2021. This would put a small company like Yingli on the forefront of a bullish market sentiment between 2021 and 2025.

The clean energy company has over 14,000 employees in the US and Canada. Together, they produce approximately 45,900 megawatts of environmentally green power every year. This resulted in a profit of over $17 billion in 2017. Shares of NextEra Energy (NYSE:NEE) rallied 27.4% in 2020, according to data provided by S&P Global Market Intelligence.
One of the great things about NextEra Energy is that the company doesn’t only produce energy. It also one of the biggest utility companies in the United States, and it invests billions of dollars in infrastructure. The company can also brag that it’s the largest single producer of wind and solar power in the world. So, it’s a hot investment pick if you’re looking for a defensive investment in a well established company.
I’m bullish on NEE, just like electric vehicles stocks in my portfolio like NIO.
2. Renewable Energy Group Inc.
As another established sustainable clean energy company, REGI is a biodiesel production company based in Iowa. The company currently operates 14 biorefineries and one feedstock processing facility.
REGI Group became a Fortune 1,000 corporation in 2018. It is now one of the most well-established clean energy companies dedicated to biodiesel.
As noted by Seeking Alpha, REGI is also uniquely positioned to benefit from growing commitments to carbon reductions from other countries, state and local governments, investors, and individual companies. Quoting management from the 2020 Investor Day:
“companies are making commitments to reduce carbon… To highlight just a couple, Amazon has made the commitment to be net zero carbon across their business by 2040, 10 years ahead of the Paris Climate Agreement; Microsoft has vowed to be carbon negative by 2030. REG has a solution today with our products to help these companies begin this hard work today. Investors are also making commitments, and they're acknowledging that everyone has a role to play. BlackRock states that every government, company and shareholder must confront climate change, we could not agree more.”

Canadian Solar Inc., together with all its subsidiaries, designs, develops, manufactures, and sells:
- Solar ingots
- Wafers

Why choose Clean/Green Energy Penny Stocks?
The rise of green energy is a defining movement of the 21st century. Governments around the world and in the US have attempted to increase the production of renewable and green energy for environmental purposes.

Geothermal energy is reliable and environmentally friendly. The efficiency it offers makes geothermal energy companies stocks another option for investors in new energy companies.
1. Ormat Technologies
Ormat Technologies has operated in California for decades. But the state’s path towards 100% sustainable energy has led regulators to consider proposals to double geothermal energy manufacturing by 2030. That’s where Ormat comes into the picture.
Ormat produces geothermal energy in 25 countries. They are now poised to benefit enormously from the new demand for its product in California. The state needs to produce energy after dark, at which point wind and geothermal energy are the most promising. This diversity will help California reach its green energy goals.

Conclusion

When mulling over the right stock to go for, the best thing to do is to do extensive research and due diligence on the organization before buying. With that being said, any scenario that involves the world’s superpowers moving away from fossil fuel consumption in the next 10 years is good news for renewables.
If I were you, I would be buying positions in companies like Next Era Energy Inc, as there is more than enough market data to tell us that this stock would be a pretty exciting investment (and profitable) opportunity.
There are tons of penny stocks to buy, I mean seriously… but the chances of you 10xing on some random companies that you choose can often end in disappointment. By avoiding certain penny stocks to buy, and focusing on a stock like Next Era Energy Inc, your portfolio will grow gradually over time rather than take a massive hit.
