I always looked at REPEAT/Rhodium analysis as best case scenario wrt clean cap additions. Lots of hard-to-model incentives and barriers that need to be overcome to reach those massive cap addn predictions
The DOE is sticking to the “deliver ability” part of the 3 pillars: energy.gov/sites/default/fil…
Despite claims of an overwhelming consensus backing the 3 pillars, deliverability makes the $3/kg subsidy hard to justify: nber.org/papers/w31902
There is a strong push for deliverability restrictions in H2 subsidies:

However, our new WP (w/ Stephen Holland and Andy Yates) presents some evidence for why we it's hard to justify our H2 subsidies if we do:

Getting a new waterheater (wh). 1st person suggests heatpump(hp) wh. 2nd guy says crawlspace is too small to install a hp wh that meets code. Both gave tankless quotes that r not eligible for IRA-tax credits. Punchline-I have no idea how much energy efficiency IRA will deliver.

Not sure I buy Duke here either, but option value is real. W/ high price volatility it’s a bigger deal. Big energy system models don’t generally pick up uncert. that drives opt. val. Would be interesting to see if cost/effic. uncertainties will delay clean energy deployment
This paper seems extremely timely given the analyses of the Inflation Reduction Act coming out that show significant reductions in transportation sector emissions

Some important changes in the Market Stability Reserve of EU-ETS announced by EC yesterday. Specifically, the release of permits from the reserve will now be price-based instead of allowances-in-circulation based, a move @_PierreNoel_ suggested: energypolicy.columbia.edu/re…
Hope they rollout in a way that allows estimates of how fixed pricing affects vmt. If my calc is right, the break-even annual miles one would have to go is pretty close to @RapsonEnergy est of avg annual vmt’s for EVs utilitydive.com/news/duke-ma…
Saw a few posts on EPIC/RhG study. Low solar/wind costs make ben-to-cost of PTC/ITC quite high now. OTH, emiss reduction is small (13% below BaU). I suspect cost effectiveness of PTC/ITC falls as we get larger emiss cuts

Of course my son’s school would have a snow day on the day I present at #ASSA2022. Et tu 2022
CGEP is hiring! The JOE ad was just posted. Looking for early-career & new PhD econs. If you're doing energy/enviro research, with an eye toward having a real policy impact, please apply. aeaweb.org/joe/listing.php?J…
Me: how did your lego figures get up there?
6yo: I put them up there.
Me: How?
6yo: I climbed up the wall.
So I live w/ Spiderman
So it's not all bad news: BBB w/o CEPP gets us some significant reductions and they model CEPP under very generous terms (no gaming, all grant $'s going to new clean energy)
Can pending Congressional legislation deliver Biden's #ClimateAction goals as #COP26 nears? Will losing the CEPP be a fatal blow? How far on the path to net-zero can we get?
REPEAT Project from Princeton ZERO Lab & @evolved_energy out today has answers @ repeatproject.org

We need to put a price on carbon and hold corporate polluters accountable. RT if you're on board.
Much written about the role of low wind gen (down about 20% ytd in some countries) in Europe’s high electricity prices for 2021. That made me wonder how volatile wind gen is in the U.S., so I took a look at plant-level wind gen data from EIA 923. 🧵1/6
So, yes, wind gen in US is prone to similarly large swings in productivity as what we're seeing in Europe, underscoring the need for long-term storage. 5/6
Wind variability is also important for #CEPP. LSE’s that meet CEPP targets w/ wind PPA’s may find clean energy rates varying considerably year-to-year. Underscores the need for a liquid clean energy credit market. More on that in this recent CGEP Q&A.bit.ly/3zs8iFI
