If I wanted to invest in renewable energy stocks, what are the most popular?

If you’re looking at renewable energy in 2026, I’d separate the established names from the more speculative solar/storage plays. The sector has also picked up another tailwind recently: governments in Europe and Asia are accelerating renewable investment as energy-security concerns increase. (reuters.com)

Here are several of the most widely followed names:

Three I would research first

1. NextEra Energy (NEE) — my starting point for a conservative renewable holding

NextEra is one of the world’s largest wind and solar producers, but importantly it also owns a major regulated utility business. That makes it quite different from betting everything on solar-panel prices.

As of late August, NEE was roughly a $174 billion company, with a dividend yield around 2.8%. The company expects rising electricity demand to support more than 8% annual EPS growth through 2032. (fool.com)

Recent price: roughly $82–84. (marketwatch.com)

Why I like the setup: renewables + electricity-demand growth + dividend income.

2. Brookfield Renewable (BEPC/BEP) — renewable infrastructure play

This is probably the most diversified pure renewable-energy name on the list.

Brookfield operates hydroelectric, solar, wind and storage assets globally. It has about 47 GW of operating renewable assets and a development pipeline exceeding 200 GW. (barrons.com)

It also has major power agreements involving companies such as Microsoft and Alphabet, which makes the AI/data-center electricity boom particularly interesting for Brookfield. (barrons.com)

BEPC is generally the simpler corporate structure for an ordinary brokerage account; BEP is the partnership version.

3. First Solar (FSLR) — higher-growth solar bet

If I specifically wanted exposure to solar, this would be near the top of my research list.

First Solar manufactures utility-scale thin-film solar modules. It had approximately 45.1 GW of contracted sales through 2030, representing about $13.6 billion of future revenue visibility as of mid-2026. (fool.com)

FSLR recently traded around $204, considerably below its 2026 high of about $321. (marketwatch.com)

That doesn’t automatically make it cheap, but it certainly makes the valuation worth investigating.

One particularly interesting 2026 story: GE Vernova

GE Vernova isn’t a pure renewable-energy company, which is actually part of its appeal.

It sells wind turbines, grid equipment and power-generation equipment. Its installed base includes roughly 59,000 wind turbines representing more than 120 GW. (gevernova.com)

But it’s also benefiting enormously from increasing electricity demand from AI/data centers. GE Vernova raised its 2026 guidance after its backlog increased by more than $13 billion in a single quarter.

The drawback is valuation: investors have already recognized much of this story.

A simple portfolio approach

If I were putting $10,000 specifically into renewable/clean-energy investments and wanted reasonable diversification rather than gambling on one solar company, an example research portfolio might look like:

$3,000 NEE + $2,500 BEPC + $2,000 FSLR + $1,500 GEV + $1,000 in a clean-energy ETF.

That gives you utility-scale renewables, hydro, solar manufacturing, wind/grid infrastructure and broader diversification.

I would not put the entire renewable allocation into ENPH, RUN, SEDG or another smaller solar name. They can produce spectacular returns, but they can also be extremely volatile.

For someone starting a renewable-energy portfolio today, NEE, BEPC and FSLR would be my first three companies to investigate, with GEV as the interesting “picks-and-shovels” addition.
