Renewable energy stocks have been popular in recent years and it’s easy to see why. With surging global electricity demand colliding with the urgent push for cleaner, more sustainable power, the renewable energy sector looks poised for strong growth in the years ahead. 

Looking to add some clean energy stocks to your portfolio? Here are six names to consider. 

SSE 

In the FTSE 100, one renewable energy stock that could be worth checking out is SSE (SSE:LON). It is spearheading major North Sea offshore wind farm projects such as Dogger Bank (which will become the world's largest offshore wind farm upon completion) while managing critical UK transmission and distribution grids.

Currently, it is executing a fully funded £33 billion, five-year investment plan designed to unlock clean, secure, and affordable energy. By FY2030, it’s targeting 9 GW in renewable energy output – enough to power 7-9 million homes instantaneously. 

One attraction of this company from an investment perspective is that it offers exposure to offshore wind, onshore wind, solar, and battery storage projects. So, it’s a diversified play on the renewable energy theme. 

Another is that it balances renewable energy assets with highly predictable, inflation-linked regulated grid networks. This further reduces risk for investors. 

At present, this stock trades on a P/E ratio of just under 15, which is a reasonable valuation. The dividend yield is about 2.7%.

Overall, it looks like a solid play on the renewable energy theme. That said, with UK prime minister Andy Burnham calling for stronger public control of energy utilities, regulatory intervention is a risk. 

Renewables Infrastructure Group (TRIG)

Another diversified play within the UK market that’s worth a look is Renewables Infrastructure Group (TRIG:LON). This is a FTSE 250-listed investment company that owns a broad portfolio of wind and solar farms across the UK and Europe. 

At present, it has investments in over 80 projects across six different power markets. Overall, its portfolio generates in excess of 2 GW of power. 

TRIG’s goal is to provide steady, sustainable returns to investors through dividends while preserving the capital value of its investment portfolio. So, it’s more of an income play. 

But don’t be put off by that because the yields here are attractive. For 2026, TRIG is expected to pay out 7.43p per share in dividends, which translates to a yield of around 9%. 

It’s worth pointing out that dividends are not guaranteed. And if cash flows from the company’s operations fall, the company could be forced to lower its payouts. 

Taking a long-term view, however, this stock has the potential to be a cash cow. It’s worth noting that at present, it’s trading at a huge discount to its NAV meaning that investors can get access to the company’s renewable energy assets cheaply. 

Ceres Power Holdings 

For a more speculative clean energy play within the UK market, take a look at Ceres Power Holdings(CWR:LON). It is a solid oxide fuel cell technology company whose ultimate goal is to help sustain a clean, green planet by ensuring that there is clean energy everywhere in the world. 

This company has a unique business model. Instead of building its own products, it licenses its technology to other industrial companies. 

For example, in late 2025, it did a licensing deal with Chinese firm Weichai Power. Under this deal, Ceres will manufacture solid oxide fuel cells and stacks for Chinese power systems supporting AI data centres, commercial buildings, and industrial applications.

It has also signed a number of strategic partnerships with energy companies. Earlier this year, for example, it announced a partnership with Centrica to accelerate the deployment of solid oxide on-site power solutions to meet the multi-gigawatt demand from commercial and industrial power customers across the UK and Europe.

Now, Ceres Power isn’t profitable today. So, it’s definitely a riskier play on the renewable energy theme. 

However, there is a lot of potential here. If the company can continue to license its technology, its revenues and share price should move higher.  

GE Vernova

In the US market, one name worth highlighting is GE Vernova (GEV:NYSE). It is a major producer of utility-scale onshore wind turbines used in large land-based wind farms globally. 

It’s also engaged in grid modernisation and high-voltage transmission. Solar and wind projects are often located far from major cities, and GE Vernova builds High-Voltage Direct Current (HVDC) transmission corridors, converter stations, and advanced substations to transport clean power long distances with minimal loss.   

This company is growing at a fast pace at present. This year, its sales are forecast to rise about 23% to $46.9 billion. 

It also has a huge backlog. As of the end of the third quarter, its backlog was almost $200 billion (about five years’ worth of sales). 

On the downside, it’s a little bit expensive – currently it has a P/E ratio of 26.5. I think that valuation is justified given the growth and backlog, however. 

First Solar 

Another US-listed renewable energy stock to consider is First Solar (FSLR:NASDAQ). It’s the largest US-headquartered solar panel manufacturer. 

It specialises in Cadmium Telluride (CadTel) thin-film technology, which is able to perform well in high-temperature and low-light conditions. And it has a focus on utility-scale projects, which protects it from residential market weakness.

An attraction of this stock is its strong long–term revenue growth. Over the last five years, revenue has climbed from $2.7 billion to $5.2 billion. 

Another thing to like is that the company is profitable ($1.5 billion in net profit last year). So, it’s a bit less risky than a lot of other smaller renewable players. 

It’s worth pointing out that First Solar’s revenues can fluctuate from year to year. For example, revenues are expected to fall in 2026 before jumping in 2027. 

This lack of consistent top-line growth adds risk. However, with the shares trading on a P/E ratio of just 10, the risk/reward looks favourable. 

Shoals Technologies

Finally, a small-cap renewable energy stock in the US that could be worth a look is Shoals Technologies Group (SHLS:NASDAQ). Sporting a market cap of just $1.4 billion, it produces electrical components that carry electricity from solar panels to the inverter and onto the power grid. 

Its competitive advantage is its plug-and-play technology. Whereas traditional solar wiring requires expensive, licensed electricians to hand-wire connections in the field. Shoals’ proprietary ‘Big Lead Assembly’ system allows any worker to install solar wiring rapidly, reducing installation costs and speeding up project completion times. 

Shoals Technologies has an impressive track record in terms of revenue growth. This year, its revenue is expected to hit $646 million versus $213 million five years ago. 

It’s also consistently profitable. For 2026, analysts expect a net profit of around $75 million. 

With the stock trading on a P/E of less than 20, I reckon it has potential. Note that the average analyst price target is about 30% above the current share price.
