Insightful @ucenergyinstitute.bsky.social post from @severinborenstein.bsky.social on California refineries. It'll get you up to speed on the facts, opportunities, and tensions as the California legislative session begins this week.

Spent so much time writing about clean air act repeal that I forgot to replace my air purifiers! We are going the direct air capture route because the actors below refuse to install scrubbers.

New blog post with my colleague on how new policy decisions expose fossil dependent grids to greater electricity price uncertainty.

UCSB researchers just released a great analysis of how to use the state's cap-and-trade program revenues to invest in energy affordability. 1 pager, policy brief, and online calculator are all great tools! emlab.ucsb.edu/projects/usi...

Reading the transferability language for PTC/ITC it seems like they repeal when the tax credit value goes to 0....
I don't see how transferability (for the PTC/ITC) is effectively changed at all?

The ways and means adjustment to IRA clean electricity tax credits are out. Phaseout of tax credits begins in 2029-2032. Modeling coming soon.

Last week, we published modeling of potential repeal of the clean energy tax credits in the IRA. We display changes regionally across the US, retail rate effects, and the emissions outcomes.
Retail electricity rates could rise between 6-10% in the next 10 years.

Emissions intensity standards (EISs) might be better equipped to address this leakage, especially if they have separate compliance instruments from existing REC markets. Here is a graph of the cost-effectiveness of these policies. A comparable EIS performs better than CES style policies.

Here is a graph from the report that shows the emissions pathways of the different policy options.
A 100% clean standard might not reach zero emissions. This is due to temporal leakage! Fossil power can still supply MD under a 100% clean standard if there are clean energy credits to cover it.

Big career moment for me! My research is cited in this year's Annual Economic Report from the White House Council of Economic Advisers.
Now I am just curious which citation 🤔

California carbon market auction prices tell a story of regulatory expectations. Initial rulemaking workshops steadily rose prices with expectations of more stringency. Since the state regulator (CARB) impact assessment and it's subsequent delays of rule announcement, prices have steadily declined.

Great article from @carbonbrief.org on China surpassing EU cumulative emissions.
The animated chart best explains the main takeaway for me: Emissions in China have grown exponentially in recent decades. Given current projections, it will become more S-shaped.

Thanks for sharing the report. I found this interesting too. We are underestimating near term projections (maybe underestimated Covid recovery) but long term outlook is looking better each year! A big win for the climate policy community with a lot more work left to do.
