Every Thursday it looks past the headlines to the incentives shaping the power market: not just what was announced, but who benefits and who’s exposed if it fails. Like CTVC did for climate tech, Powerstack aims to be the clearest read on the week in power, written for experts who already speak the language of market design, regulatory frameworks, and capital structure. Read the first issue here and subscribe to receive event invites, the latest Sightline Climate research, and be part of our network.

Quick reminders:

Early-Bird Access to the 2026 SF Climate Week calendar is still live.

You can view a preview of some of the 100+ events on the Early-Bird calendar here: https://bit.ly/SFCW26-Early

If you’re still interested, you can still get Early-Bird Access to 100+ events here.

Early-Bird Access costs $29. That fee directly supports our team’s work in coordinating and making SF Climate Week happen, and helps keep this a strong, independent, community-supported initiative.

We’re grateful to all of you who’ve already signed up for Early-Bird Access — thank you. We’re thrilled to hear how valuable the head start has already been for so many of you.

The full public calendar will go live for free in mid-March. But if you want early access before more events fill up — while also supporting SF Climate Week and our mission — Early-Bird Access is the best way to do it.

This week, the United States launched a war in the Middle East for the fourth time in as many decades, and the impact on energy markets has been swift. What is less clear is whether the war could unwittingly present an opportunity for renewables at the same time that an emerging order of countries taking climate action as a matter of national security is beginning to take shape.

The fallout of war with Iran may still be unpredictable, but it is not unprecedented. Two weeks ago marked the fourth anniversary of Russia’s invasion of Ukraine, and just as that military action provoked an energy shock that shapes Europe’s energy transition today, the world’s economies are once again confronting the vulnerability of fossil fuel supply chains during wartime.

On Tuesday, Iranian officials responded to American and Israeli strikes by effectively closing the Strait of Hormuz, a narrow passage connecting the Persian Gulf with the Indian Ocean. Roughly one fifth of the world’s oil and gas supply passes through the strait, and its closure has already pushed gas prices up roughly 50 percent in Europe. Iran has also launched missile attacks on the world’s largest oil refinery in Saudi Arabia, as well as a major natural gas hub in Qatar, forcing both facilities to shut down indefinitely.

Within weeks of Russia’s invasion of Ukraine in 2022, Europe cut off its supply of Russian coal, oil and gas, triggering an energy crisis that lasted into 2023. European officials responded by doubling down on renewables through an initiative known as REPowerEU.

The question now is whether the latest energy shock will produce a similar response.

This time around, energy analysts are divided on whether the spike in energy prices will lead countries to deploy more renewables in an effort to shore up electricity supply. On the one hand, expanding wind and solar installations would allow countries cut off from fossil fuels passing through the Strait of Hormuz to generate more electricity domestically.

But some analysts remain skeptical, pointing to the possibility that higher energy costs could provoke global inflation, leading to higher interest rates from central banks. Those interest rates influence the cost of borrowing money, as wind and solar projects rely heavily on cheap financing because of their high upfront costs. They also point out that the region most affected by restrictions from the Hormuz Strait is Asia, where many countries could simply burn more domestically available coal to compensate for lost gas and oil.
