3 Renewable Energy Stocks To Own In September 2026

Higher long term bond yields are putting pressure on expensive growth plays and capital intensive projects, which is quietly pushing more attention toward businesses that generate power from the sun, wind and water. Cash flows that are tied to essential energy can look appealing when money is no longer cheap. This article walks through three renewable energy stocks from the US market that fit this theme and may warrant a closer look.

The three stocks below are only a sample, and the full renewable energy screen surfaced 20 more companies with equally compelling narratives that are not covered in this article.

If you want to identify your own highest conviction ideas across solar, wind, hydro and tidal power, head straight to the Renewable (solar, wind, hydro or tidal) Energy screener.

Clearway Energy (CWEN)

Overview: Clearway Energy operates a large US portfolio of wind, solar and battery storage assets, plus smaller combustion based power plants.

Operations: Clearway Energy generates about US$1.25b from Renewables & Storage and US$320 million from Flexible Generation, all within the United States.

Market Cap: US$6.0b

Clearway Energy matters for this screener because most of its business comes from operating real wind, solar and storage projects across the US. This gives investors direct exposure to contracted clean power rather than only to equipment or development risk.

"Expansion of late stage wind, solar and storage projects, with 100% of 2026 and 2027 vintages already commercialized and a 2028 to 2029 pipeline larger than what is needed for internal CAFD targets, gives the company multiple ways to add contracted capacity that can lift CAFD and support dividend coverage."

The key variable is how one pressure on future project economics ultimately shapes cash flow per share and long term dividend comfort.

That pressure on future project economics is exactly what the full narrative for Clearway Energy unpacks in detail, including how Clearway Energy’s growth pipeline interacts with financing risk.

Ormat Technologies (ORA)

Overview: Ormat Technologies develops, owns, and operates geothermal and solar power plants worldwide, selling renewable electricity and related equipment and services.

Operations: Ormat Technologies generates about US$705 million from Electricity, US$349 million from Product, and US$134 million from Energy Storage, with US$649 million from the United States.

Market Cap: US$5.6b

Ormat Technologies matters for this renewable screen because its geothermal power fleet provides round the clock clean electricity rather than weather dependent output.

"Recent federal permitting reforms and policy support have significantly expedited geothermal project development timelines in the U.S., enabling Ormat to accelerate greenfield expansion and release more projects for construction."

The real swing factor is how one unresolved cost pressure shapes future project returns, especially for storage-heavy geothermal expansions.

That unresolved cost pressure is exactly what the full narrative for Ormat Technologies breaks down, separating near term headwinds from longer term opportunities in Ormat Technologies’ geothermal and storage build out.

ReNew Energy Global (RNW)

Overview: ReNew Energy Global develops, owns, and operates large scale wind and solar projects across India, selling renewable electricity and related services.

Operations: ReNew Energy Global currently generates ₹137,779 million in revenue from India, reflecting its focus on domestic renewable power and services.

Market Cap: US$2.49b

ReNew Energy Global matters for this renewable screen because it runs a vast on the ground fleet of wind and solar assets in India, with in house services and manufacturing that tie directly into building and operating clean power projects.

"Accelerated project execution, strong ESG credentials, and advanced manufacturing are cited as drivers of revenue and margin growth, alongside access to green capital and premium corporate mandates."

The future path of ReNew Energy Global's earnings depends in part on how one underappreciated pressure shapes the actual cost of funding its expansion.

That funding pressure is exactly what the full narrative for ReNew Energy Global unpacks, tying ReNew Energy Global's capital costs to project pacing, contract quality, and any potential upside if financing conditions ease.
