Consequences of the missing risk market problem for power system emissions
Liberalized power markets are characterized by a missing market problem: a limited availability of long-term contracts leaves risk-averse investors ex…

Are electricity markets aligned with decarbonization goals? 🔌💡
In a new paper, I and co-authors show that market frictions in long-term contracting can hinder decarbonization. We are likely under-investing in clean energy.

Do climate policies bring risk-mitigation co-benefits? We find that in some cases they do, & that this matters for the CO2 price vs. subsidies debate.

States should make sure data centers are accompanied by more zero-fuel-cost capacity and transmission.
$16 billion. That's how much the PJM market monitor estimates that electricity ratepayers will pay via increased utility bills to subsidize interconnection of data centers owned by Big Tech. A massive give-away to some of the most profitable companies in the world.

Can confirm.
It's weird - but now in Oslo, there's so many EVs that you notice the noise and the smell from individual ICE cars, and you realise how much we've been normalising it for ever. You can smell them half a street away.
And inside parking lots are just *quiet*.

It's absolutely astonishing: In just about 13 years, Norway has skyrocketed from virtually no sales of zero-emission battery electric vehicles to nearly 100% of all new passenger car purchases.

Can confirm.
Remember those data centers raising electricity prices? In many cases, they are also getting taxpayer subsidies.

It's increasingly common to see a justifiable worry that AI data centers will raise electricity prices for ordinary consumers. What should we do about that?
There's a lot of remedies, but one overarching solution is to build more wind, solar, and batteries. Why? I am so glad you asked. 1/5
