Annual Sustainability & Energy Transition Primer 2026

What You Need to Know:

• The energy transition remains intact.
• The market is rewarding near-term earnings power, commercial execution and technologies that can solve immediate grid, power and reliability bottlenecks.
• AI-driven data center load growth, electrification and grid underinvestment are creating a more favorable setup for grid modernization, storage and next-gen power electronics.
• We think capital is becoming more selective and should continue to favor scaled companies with proven products and direct exposure to the highest-priority power bottlenecks.

The TD Cowen Insight

Our 11th annual comprehensive primer on the Sustainability & Energy Transition sector aims to assist investors in navigating its complex and varied sub-verticals. We remain bullish on long-term prospects but see policy uncertainty and high interest rates slowing the pace of project development.

Our Thesis

The energy transition is intact, but in 2026, investors care far more about earnings visibility, commercial viability and speed to power than thematic excitement. The biggest opportunities are centered on AI/data center-driven electricity demand, grid modernization and scalable power solutions that can deliver reliable returns despite economic uncertainty.

The unsubsidized levelized cost of energy (LCOE) for renewable power choices (e.g. solar, storage and onshore wind) remain compelling relative to the marginal cost solution, combined cycle gas turbines (CCGT). We continue to expect the LCOE of renewables and CCGT to diverge. Renewables benefit from declining hardware costs and technological advancements. At the same time, CCGT faces a supply squeeze; an explosion in power demand over the past year has led to a tripling of natural gas equipment costs with lead times out to 2029+.

We note that not only are renewables the lowest-cost source of power generation, but they are also the fastest to build and a significant competitive edge in a constrained grid environment. Solar + storage has the potential to be 50% of the cost of new CCGT by 2030.

What You'll Find in Our Full Research Report

We have compiled a 300+ page primer on the sector. It's the collaborative effort of five TD Cowen senior analyst teams spanning various industries, plus our Washington Research Group (WRG) Energy Transition & Sustainability analyst. The report forms a comprehensive view of the sustainability and energy transition ecosystem, current key themes impacting stock performance and potential investment considerations for stakeholders. Within this report, we provide a thorough analysis of IRA revisions enacted by the OBBBA last year, and the subsequent Treasury Department guidance.

We also explore the implications of AI-driven growth in electricity demand. Our Smart Grid section dives deeper into the state of play for grid-edge intelligence sensors and the value they can provide to utilities.

Financial and Industry Model Implications

Our forecasts consider the increasing need to leverage technology (both networking and software) that manages distributed energy resources. We also consider key pillars of grid modernization needed to better manage the US$3 trillion global electricity market. Key drivers and forecasts by the industry form our overall sector view and are outlined within the report.

What To Watch For

Looking ahead, we see ten mega energy transition themes playing out:

1. Data center load growth is straining the grid, with renewables and gas playing key roles.
2. The electrotech revolution is shifting energy from fossil-fuel combustion to electrically driven technologies.
3. Electricity affordability is becoming a politically charged issue.
4. Electricity reliability is under pressure as reserve margins shrink.
5. Data center BYOP (Bring Your Own Power), BYOC (Bring Your Own Capacity), and our favorite, "BeYONCE" (Bring Your Own Clean Energy) reflects large loads bringing their own power or capacity.
6. Grid investment is badly needed to handle load growth.
7. The Iran war is resetting the global energy security narrative.
8. Higher-for-longer interest rates are reshaping sector economics with...
9. ...trade and policy issues in 2H26 remaining important to monitor.
10. New data center power electronics architectures are creating opportunities for fuel cell, storage and inverter companies.

Our highest-conviction long-term ideas for the energy transition over the next three to five years are aligned with utility-scale power, grid modernization, geothermal and selected international residential and commercial opportunities.
