Top 3 Clean Energy Stocks To Watch In October 2026

Oil prices recently moved above $111 a barrel after attacks on Saudi energy facilities, which reminded markets how reliant the world still is on fossil fuels. That shock is one reason investors are paying fresh attention to businesses building cleaner power sources from sun, wind and water. This article breaks down three renewable energy stocks from our specialist screener that could help you position your portfolio for that long term shift.

The three stocks below are just a starter pack, while the full renewable screen surfaced another 214 listed businesses with equally detailed stories that are not covered here. To go broader and deeper, head straight into the Renewable (solar, wind, hydro or tidal) Energy screener to identify, filter and analyze the renewable energy operators that best fit your own portfolio plan.

Doral Group Renewable Energy Resources (TASE:DORL)

Doral Group Renewable Energy Resources develops, builds, owns and operates solar power installations with storage across ground sites, rooftops and water surfaces, alongside wind farms and green hydrogen projects. Most revenue comes from renewable energy activities, led by ₪446.1 million from Electricity from Nature. The group has a roughly ₪11.1b market cap.

Doral Group Renewable Energy Resources provides direct exposure to large scale solar PV and storage projects, with Q2 2026 revenue of ₪183.75 million and a quarterly profit after earlier losses. The business remains unprofitable over six months, so long term returns depend on how pressure in its funding model is resolved.

If that funding pressure is on your mind, read the Doral Group Renewable Energy Resources financial health report to see how Doral Group Renewable Energy Resources is positioned for the next phase.

Corporación Acciona Energías Renovables (BME:ANE)

Corporación Acciona Energías Renovables runs and services large onshore wind farms and utility scale solar plants, with most income tied directly to these renewables projects. The group generated around €1.28b from wind, €222 million from photovoltaic and €86 million from biomass and solar, and has a roughly €7b market value.

Corporación Acciona Energías Renovables gives you exposure to the build and operate phases of big wind and solar parks, where long asset lives can create steady cash flows, but execution, funding and policy all matter for outcomes. That tension comes through clearly in the way management is reshaping the portfolio.

"Although the company leans on repeated asset disposals at high €/MW valuations to fund growth and cut net debt, reliance on achieving around €2b of 2026 rotation proceeds after already completing €3.2b in 2024 and 2025 raises the risk that weaker pricing or reduced buyer appetite would leave a gap in planned deleveraging and non recurring gains, pressuring earnings quality and leverage targets."

The outcome of a single pressure point in that plan shifting will likely decide whether future returns track expectations or drift away.

If that turning point is what concerns you, read the full narrative for Corporación Acciona Energías Renovables to see whether current rotation plans are masking risk or setting up a stronger runway.

ERG (BIT:ERG)

ERG is a pure play on utility scale renewable generation, with most income tied to wind and solar farms that feed power grids across Europe and the US. The stock’s roughly €3.2b market value reflects a sizeable listed operator in this space. Wind contributes about €634 million of revenue and solar adds roughly €140 million, underscoring how tightly this business is linked to the Renewable Energy screener theme.

For investors who want a listed operator that lives and breathes grid scale renewables, ERG brings a mix of contracted projects, repowering work and new storage capacity that could reshape how its earnings behave through the next power cycle.

"Acceleration of organic growth through about 230 MW of capacity under construction and roughly 700 MW of wind repowering and battery storage projects targeted for FIDs by end 2026, backed by about €1.0b of associated CapEx, could add contracted volumes that support future EBITDA and earnings."

The real swing factor is how one still unresolved pressure on future cash generation plays out against that growing fleet of green assets.

That unresolved cash flow question is exactly what the full narrative for ERG unpacks for ERG, separating temporary funding friction from long term earnings power.
