In this article, we will talk about the 10 biggest green energy companies in the world.
Green energy refers to energy generated from renewable resources, such as sunlight, wind, and water. As global warming and climate change continue to raise alarms for economies around the world, the transition to clean and green energy is on everyone’s radar. While the pandemic caused many businesses to shut down and industries to suffer losses, the renewable energy industry flourished as investments in the sector boomed.
Green Energy Market: An Analysis
According to a report by International Energy Agency, renewables were the only energy source that saw an increase in demand in 2020 despite the Covid-19 pandemic. Annual renewable capacity additions were up to 280 Gigawatts (GW) in 2020, up 45% year over year. Global wind capacity additions were up by over 90% in 2020 and came to 114 GW, a 50% increase on pre-pandemic levels. Solar Photovoltaic development is expected to top 162 GW in annual additions by the end of 2022, a 50% increase from the pre-pandemic levels in 2019.
According to BloombergNEF, global investment in the energy sector was a record $755 billion in 2021. The major chunk of this investment was attributed to the renewable energy division, which included wind, solar, and other renewables. The investment in the renewables sector topped $366 billion, up 6.5% from 2020 numbers. The second-largest sector by investment share was electrified transport, with $273 billion invested in 2021.
An “Irreversible Path” Towards Green Energy
A major catalyst driving the demand for renewables and green-energy sources around the world is governments’ efforts to battle climate change. In 2020, President Biden laid out a $2 trillion plan to battle climate change and put the U.S. on an “irreversible path” targeting net-zero carbon emissions by 2050. The Biden administration proposed the Build Back Better plan which includes tax benefits for investments in the renewable energy sector. According to the Renewable Energy Market Outlook 2030, by Allied Market Research, the global renewable energy sector was valued at $881.7 billion in 2020 and is expected to rise to $1.97 trillion by 2030 at a compound annual growth rate of 8.4% over the forecasted period
Another catalyst that is causing green energy stocks to soar is the ongoing war between Russia and Ukraine. The sanctions placed on Russia have caused massive supply chain disruptions and commodity prices to skyrocket. BofA chief economist, Ethan Harris, estimates that oil prices could double to $200 per barrel as a consequence of losing Russia’s 5 million barrels.
“If the West cuts off most of Russia’s energy exports it would be a major shock to global markets,” said Harris.
The price per barrel of Brent Crude oil went up by 33% since Russia invaded Ukraine on February 24, 2022. It almost reached $140 a barrel earlier this March nearing its 2008 historic high. This means more business for green energy companies and has caused green energy shares to gain. Some of the biggest green energy companies in the world include NextEra Energy, Inc. (NYSE:NEE), SolarEdge Technologies, Inc. (NASDAQ:SEDG), Plug Power Inc. (NASDAQ:PLUG), and Enphase Energy, Inc. (NASDAQ:ENPH).

8. Sunrun Inc. (NASDAQ:RUN)

Number of Hedge Fund Holders: 31
By the end of the fourth quarter of 2021, 31 funds were bullish on Sunrun Inc. (NASDAQ:RUN) and had stakes worth in excess of $1 billion. Of these funds, Tiger Global Management LLC was the dominating shareholder in Sunrun Inc. as of March 10, 2022. Tiger Global’s stakes in the company equaled $242.61 million, which accounts for 0.52% of the fund’s investment portfolio.
As of March 23, 2022, Sunrun Inc. has a market capitalization of $6.35 billion, which makes it one of the biggest green energy companies in the world. Other major players in the green energy industry include NextEra Energy, Inc., SolarEdge Technologies, Inc., Plug Power Inc., and Enphase Energy, Inc..
Horizon Kinetics, an investment management firm, published its second-quarter 2021 investor letter in which it mentioned Sunrun Inc.. Here’s what the firm had to say:
“What this table did not cover is valuation. What’s expensive, what’s cheap? A good business that is too expensive is not a good investment. The most expensive business in the table is Sunrun. Sunrun is the nation’s largest residential rooftop solar panel system seller/installer. Sunrun’s valuation might also shed Thumbnail valuation.
To start at the top of the income statement, Sunrun shares trade at 10.3x revenues. The most profitable company in the S&P 500, Microsoft, trades at 13x revenues. Sunrun operates at a loss. Obviously, not only is tremendous growth anticipated, but tremendous profitability, too.
Let’s simply accept that investors have correctly anticipated Sunrun’s future success and make that the starting point for a valuation exercise.
If, 10 years from now, Sunrun is ultimately valued at 25x net income, and if today’s $9.5 billion valuation is appropriate, that would require $380 million of net income ($9,500 million ÷ 25).
Let’s say Sunrun will have the same net profit margin as the average S&P 500 company, which is 10%. That means it would need $3,800 million of sales to generate that level of earnings ($380 mill ÷ 10%).
Since sales are now $920 million, they would have to rise by 4.1x in the next 10 years. That would require annual sales growth of 15.2%.
You see how neatly that all works: investors accept the company’s 10-year, 15% annual sales growth projections, and if a 10% net profit margin and a P/E of 25x earnings are reasonable, then the company will have a $9.5 billion market cap at that time. Except that is the current price. That means a 10-year
return of zero.In order to get a 10% annualized return from the stock, Sunrun would need to be priced at a P/E of 65x its earnings 10 years from now, if at a 10% net margin. Or it would have to have some combination of lower P/E and higher growth and/or higher profit margin.
In the meantime, this is Sunrun’s recent pattern of revenue growth and profitability (the company did recently increase its estimate of installed-capacity growth in 2021 from 20-25% to a new estimate of 25% to 30%).
For the time being, Sunrun loses an extraordinary amount of money, an amount that has been getting larger. Perhaps there are scale economies that will manifest in the future, so that it will attain profitability. Perhaps from the roughly one-half of Sunrun’s revenues that are from long-term customer service
agreements that run up to 25 years. For now, though, the company would seem to require a lot of external financing, and that is one of the greatest of business risks.”
