The hugely negative impact caused by fossil fuels has prompted a much greater focus on ‘green’ energy sources over the past few years. Due to this, more companies than ever are looking to aid the decarbonization effort and produce renewable energy that is much more sustainable and eco-friendly.
With that in mind, this guide takes an in-depth look at the most popular renewable energy companies to invest in. We’ll discuss ten renewable energy stocks with positive long-term value prospects before highlighting some of the main reasons why these stocks are so highly sought-after.
10 Popular Renewable Energy Companies Among Investors in 2025
Listed below are ten of the most popular renewable energy companies to invest in this year, derived through extensive research and industry analysis. We’ll examine each of these companies in the following section, covering what they do and how they make a positive environmental impact.
A Closer Look at the Biggest Green Energy Company Stocks
Renewable energy stocks have increased in popularity over the past few years as more investors are looking towards companies with a robust sustainability agenda. However, as a result of the tremendous growth in the renewables sector, it can be challenging for investors to decide which companies to invest in.
To help streamline this process, detailed below are some of the most popular renewable energy companies stocks on the market right now – each offering a way for investors to gain exposure to this rapidly-expanding sector.
1. IMPT (IMPT) – Best Renewable Energy Company to Invest In
Topping our list of the most popular renewable energy companies to invest in is IMPT. The first thing to note about IMPT is that it isn’t actually a company – it is a cryptocurrency project. However, given its ambitious goals within the realm of renewable energy, IMPT is an excellent alternative for those who are interested in other asset classes.
So what is IMPT? Broadly speaking, IMPT is a carbon credits ecosystem hosted on the Ethereum blockchain, allowing individuals and companies worldwide to buy, sell, and trade these credits. The concept of carbon credit trading has become increasingly popular in recent years, with IMPT primed to take advantage of this trend.
However, IMPT’s unique approach is what really sets it apart. The carbon credits in IMPT’s ecosystem are structured as NFTs, meaning they are immutable and fully traceable. This removes the unfortunate ‘double spend’ problem in the carbon credits market and ensures accurate CO2 offset data across the board.
Individuals looking to buy carbon credits tend to have their hands tied, as the market is still relatively inaccessible. IMPT looks to change this by partnering with thousands of well-known brands operating in various sectors, including retail, electronics, wellness, and more.
Each of these brands has pledged to allocate a percentage of its sales margin to high-impact projects. When an IMPT user shops with one of these brands, they will receive ‘IMPT Tokens’ as a reward. These ERC-20 tokens are IMPT’s native currency – meaning that once an individual has accrued enough, they can instantly swap them for a carbon credit.
This process is a key reason as to why IMPT could become one of the top green energy companies, as it makes buying carbon credits simple and easy. The credits can be traded on IMPT’s marketplace or even ‘retired’ completely. If an individual opts for the latter, they’ll be given a unique digital artwork NFT as a reward.
Those looking to invest in clean energy will naturally gravitate towards IMPT, given the project’s partnership with strictly-audited renewables initiatives worldwide. IMPT also ensures that each initiative follows Global Certification Protocols (GCP), helping to avoid fraud.
IMPT’s presale phase is currently ongoing, allowing investors to buy IMPT tokens early at a discounted price. Phase one of the crypto presale sees tokens priced at just $0.018, the lowest price they’ll be made available. Only 600 million tokens are allocated at this price – and since IMPT raised a staggering $1m in the first three days of its presale, there’s every chance these tokens could sell out.
2. Brookfield Renewable Partners (NYSE: BEP) – One of the Largest Publicly-Traded Green Energy Companies
Another of the most popular renewable energy companies to invest in is Brookfield Renewable Partners. Brookfield Renewable is a Canada-based company that operates hydroelectric plants, wind farms, and solar facilities, producing around 21 gigawatts of clean energy each year.
However, Brookfield Renewable makes our list because the company has a development pipeline that would bring its energy capacity to just under 100 gigawatts of clean energy. As such, this company has emerged as a viable option for those interested in sustainable investing.
Brookfield Renewable is also in a prime position to benefit from the worldwide decarbonization effort. Since the company offers both wind and solar power solutions, two of the fastest-growing areas of the renewables market, there’s already a significant buzz around the company’s prospects.
Interestingly, Brookfield Renewable even offers a healthy dividend yield of 3.96% at the time of writing – meaning it’ll appeal to those interested in dividend stocks. Given these characteristics, it’s clear why Brookfield Renewable is one of the most popular green energy companies to invest in.
3. Verbund AG (VIE: VER) – Largest European Renewable Energy Companies Stock
Verbund AG is the largest electricity supplier in Austria, providing power to over a third of the country’s population. This makes it the biggest renewable energy company in Austria since nearly all of Verbund AG’s electricity is generated via hydropower.
Although Verbund AG is listed on the Vienna Stock Exchange, US-based investors can still purchase shares through the OTC markets or via trading platforms that offer access to international stocks. The company’s shares have been on a sustained uptrend since the lows of March 2020, benefitting from rising energy prices worldwide.
Aside from hydropower, Verbund AG also produces electricity using thermal and wind power. The company has three wind farms in Austria, although it is in the process of expanding into other countries in Europe. Verbund AG also has nine thermal power plants, producing 900 million kWh of heat each year.
Much like Brookfield Renewable, Verbund AG is one of the world’s top green energy companies, evidenced by its €30bn market cap (as reported by Yahoo Finance). The company also offers a small annual dividend, equating to a yield of 1.5%.
4. Tesla (NASDAQ: TSLA) – Top Renewable Energy Company in the Electric Vehicle Sector
Tesla needs no introduction, as this electric vehicle behemoth has risen to prominence over the past decade under Elon Musk’s leadership. Although most investors opt to buy Tesla stock due to its foothold in the EV market, the company is also involved in renewables.
The primary way that Tesla is making an impact in the renewables sector is through its subsidiary, Tesla Energy. This company produces various renewables products, including solar panels, solar roofs, battery energy storage products, and more.
According to reports, solar installations by Tesla Energy increased by 68% in 2021 compared to 2020. Overall installations were also up by 32%, mainly due to the popularity of Tesla’s ‘Megapack’ storage system.
From an investment perspective, Tesla’s shares have also performed admirably, up 904% over the past five years and significantly outpacing the growth of the NASDAQ and S&P 500. Due to this, Tesla’s stock will likely continue appealing to those interested in green energy investing.
5. Orsted A/S (OTC: DNNGY) – World’s Largest Producer of Offshore Wind Power
Orsted A/S is a Denmark-based energy company that is currently the world’s largest producer of offshore wind power. According to Orsted’s website, the company has a market share of 25% and has built enough offshore wind farms to serve 15 million people.
However, Orsted isn’t stopping there, as the company’s management aims to double this figure by 2025. Notably, Orsted has also set some lofty sustainability goals, aiming to go carbon-neutral by 2025 – and even remove carbon emissions entirely by 2040.
As Denmark’s biggest renewable energy company, Orsted generated over 77.6bn DKK in 2021 – which equates to approximately $10.2bn. The company’s income continues to grow, with the most recent quarter ending June 2022 seeing a remarkable 94% revenue increase year-over-year (YoY).
However, from a share price perspective, it’s been a tough year for Orsted thus far. Shares are down by 28% at the time of writing – although much of this poor performance can be attributed to the ongoing situation in Ukraine, which is causing instability throughout Europe and hampering Orsted’s operations.
6. First Solar (NASDAQ: FSLR) – One of the Biggest Renewable Energy Companies in the Solar Industry
As the name suggests, First Solar is a US-based solar panel manufacturer founded back in 1990. Over the past 30 years, First Solar has solidified itself as one of the world’s largest solar contractors thanks to its cost-effective solutions.
As one of the largest renewable energy stocks in the US, First Solar generates over $2.9bn in revenue each year. However, 2022 has been challenging for the company, as supply chain constraints and rising inflation has eaten away at its margins – meaning net income was down by 32% in Q2 2022 on a YoY basis.
There are still reasons to be hopeful about First Solar’s future; most notably, the Inflation Reduction Act passed by the Biden administration. This bill will provide federal tax credits to individuals who install solar panels on their homes – helping boost demand for First Solar’s products.
Moreover, industry reports estimate that solar power could make up over 10% of US power production over the coming years. As such, renewable energy companies stocks like First Solar will be in a prime position to benefit from this shift away from fossil fuels.
7. NextEra Energy (NYSE: NEE) – Green Energy Companies Stock with Decarbonization Goal
NextEra Energy is one of the largest energy companies in the US, capable of generating around 58 gigawatts of electricity each quarter. Although NextEra Energy still works with fossil fuels, the company has begun to speed up its transition into renewable energy sources.
For example, data from Statista notes that NextEra Energy’s renewable energy capacity in 2021 reached more than 23 gigawatts – a 7% increase from 2020. Most of this renewable energy is produced through wind power, although the company also operates in the realm of solar power.
NextEra Energy is often considered one of the top ESG investing stocks since it is one of the few renewables firms that pay a competitive dividend. At the time of writing, NEE shareholders receive an annual yield of 2.10% – higher than the S&P 500 average in 2021.
Looking ahead, NextEra Energy’s team has set itself a goal of eliminating carbon emissions from its operations by 2045. The company will achieve this by shifting entirely to solar, nuclear energy, renewable natural gas, and green hydrogen. This goal has made NextEra Energy one of the most popular renewable energy companies to invest in this year.
8. SolarEdge Technologies (NASDAQ: SEDG) – One of the Leading Green Energy Company Stocks for Battery Storage
SolarEdge Technologies is one of the few new renewable energy companies focusing on both solar power generation and battery energy storage. Although SolarEdge is headquartered in Israel, the company has expanded rapidly in recent years and now has locations in the US, Italy, Japan, and Germany.
Instead of directing its attention solely on producing solar panels, SolarEdge has developed an innovative way of managing the electricity being produced. Using SolarEdge’s products, the user can store excess electricity and use it when required rather than waste it.
This process is facilitated through a handy app, making it easy for consumers to operate. Furthermore, much like with First Solar, SolarEdge will also benefit from federal tax credits being given to homeowners who generate their power from solar.
Due to its focus on renewable energy, SolarEdge is a viable option for those interested in socially-responsible investing. The company’s revenues also continue to grow YoY, highlighting its investment potential.
9. Plug Power (NASDAQ: PLUG) – One of the Most Popular Up-and-Coming Green Energy Companies
Those looking for renewable energy company stocks with a focus on ‘green hydrogen’ may wish to consider Plug Power. Although hydrogen isn’t usually considered ‘renewable’, green hydrogen is because it is produced by splitting water using renewable energy sources.
According to Plug Power’s website, the company projects to use over 80 tons of hydrogen in 2024 and pledges to ensure that 50% of this is ‘green hydrogen’. Moreover, Plug Power has noted that it will utilize renewable natural gas in the future in the hydrogen production process, helping reduce carbon emissions.
Plug Power’s focus on green hydrogen could also be beneficial from a financial perspective. A recent report from the ICIS found that producing green hydrogen is far cheaper than producing hydrogen using non-renewable electricity sources.
Finally, Plug Power’s CEO has even expressed optimism that green hydrogen and fuel cell technologies could replace diesel in the coming years. So, although the company is still unprofitable, it is still seen as having positive growth potential.
10. Clearway Energy (NYSE: CWEN) – Renewable Energy Company with a Competitive Dividend Yield
The last entry on our list of the most popular renewable energy companies to invest in is Clearway Energy. Clearway Energy is a renewable energy company focusing on solar and wind power generation in North America.
According to the Financial Times, Clearway Energy has over 5,000 net megawatts of installed solar and wind generation projects. Thanks to beneficial macroeconomic factors, Clearway Energy increased its net income from renewable sources by an impressive 207% in Q2 2022 compared to Q2 2021.
Notably, Clearway Energy generates revenue by selling the power it produces to utility companies. This means it has a relatively stable and predictable income stream, allowing the company to pay shareholders a dividend yield of 4.43% per year – ideal for those interested in earning passive income.
Broadly speaking, renewable energy companies are those involved in producing and supplying electricity that is generated using renewable sources. According to the official UN website, some of the most widely-used renewable energy sources include:
Solar energy
Wind energy
Geothermal energy
Hydropower
Ocean energy
Bioenergy
The key feature that differentiates these energy sources from fossil fuels is given in their name – they are renewable. This means that these sources will never run out since they are self-replenishing. Moreover, renewable energy sources often produce low (or no) carbon emissions, making them more eco-friendly.
According to Statista, the global renewable energy market was valued at $613bn in 2020. However, the market is projected to value around $1.1trn by 2027 – equating to a growth rate of 79%.
As a result of the sector’s rapid growth, those interested in ESG investing have started to gravitate towards renewable energy companies, as evidenced by the scale of the companies we explored in the previous section. Many renewable energy company stocks have experienced triple-digit returns in the past few years due to this increased demand – and this trend shows no signs of slowing anytime soon.
Why do People Invest in Green Energy Companies?
Individuals who invest in stocks typically do so for capital gain – yet there are also other reasons why green energy companies may represent an attractive option. Let’s take a closer look at some of these reasons:
Helps Make a Positive Environmental Impact
One of the main reasons people invest in green energy companies is due to their positive environmental actions. Unlike fossil fuel companies, green energy companies actively reduce (or remove) their carbon footprint by using ‘clean’ methods of energy production.
Given that carbon dioxide emissions are one of the leading contributors to global warming, these green energy firms will be crucial to slowing down climate change in the coming years and decades. As such, they are an attractive option for ESG-focused investors.
Potential for High Returns
Many analysts argue that the most undervalued stocks operate in the renewables sector. This is because governments worldwide are ramping up their decarbonization efforts, making renewable energy a more in-demand option.
Naturally, this is hugely positive for renewable energy companies, as the increased demand for their ‘products’ helps increase economies of scale and boost profits. In turn, this makes them more appealing from an investment perspective.
Promotes Technological Innovation
Another reason that people invest in new renewable energy companies is their innovative properties. Just a few decades ago, the concept of ‘renewable energy wasn’t fully understood. Fast forward to today, and hundreds of companies worldwide operate in the sector.
The reason for this is the rate of technological innovation fostered by these companies – with energy sources like ‘green hydrogen’ and ‘renewable natural gas’ being the latest to make waves in the sector. As demand for renewable energy continues to rise, there’ll be even more innovation as many companies strive for net-zero emissions in the coming years.
Makes Fossil Fuel Companies Less Popular
Although many investors still add oil stocks to their portfolios, it’s clear that fossil fuel companies are growing less and less popular. Not only is this due to their negative environmental impact, but also because the sources used by these companies are finite.
Thus, as renewable energy companies continue to grow in stature, the necessity of electricity produced by fossil fuel companies will wane. Over the long term, fossil fuel companies will likely become a thing of the past since renewable energy is essentially ‘futureproof’.
