@ShanuMathew93 I use forecasts as guides to general direction of variables and relative sizes of changes (eg solar and wind will both grow but solar likely grows faster). I use EIA for data, not forecasts. Still work to do there but @EIA_One has ‘em on the right track

@HarrisonGFell What do you use to forecast instead then? What do you think of EIA? Btw know where the chart is from?

@MargrietKuijper @JesseJenkins @bprest @DxGordon emiss implications of less LNG is not as simple as that for oil. Reduction in Q demanded of oil from a field retirement is likely met with fewer ICE miles driven and more EVs, both lead to lower emiss. Reduced Q demanded of LNG b/c of higher prices can be met w/ higher emiss fuel

@JesseJenkins @bprest @HarrisonGFell @DxGordon Are supply-side oil production interventions really comparable to LNG supply-side permitting interventions? The whole gas-coal interaction is missing on the oil side. US LNG exports could be replaced with cleaner alternatives, but also with coal.

@stroebel_econ It’s unfortunate that this Fed conf is on the same day as the Assoc of Enviro & Res Econ Summer Conf, where there will be (and have been for many years) many climate econ papers presented

@noahqk @SpenceEnergyUT Yes, this result is basically b/c all the HPs are in the SE and they've been heavily subsidizing them for many years here. Would be interesting to see if this result still holds in NE and MidWest as they start to adopt.

@mikejrob So I buy that they’re hard to measure, but then at what rate should govt subsidize them and doesn’t the subsidy create all the same leakage potential as offset crediting?

Maybe someday we'll have perfect measurement, global pricing, and global enforcement. We'll just need to eliminate most net emissions long before that day. So, yeah, let's subsidize forest restoration. Just don't say it's a substitute for emissions reductions.

I think @JesseJenkins is right, but this will irk some economists who often think in terms of "getting the price right" and "the law of one price." If you can sequester your emissions and be net zero, why should that be different than zero emissions? A short 🧵.
Jesse D. Jenkins@JesseJenkins

This is the KEY point when it comes to soil carbon and other 'natural climate solutions.' They are real, important mitigation options. But they are NOT viable as *alternatives* to reducing direct fossil related greenhouse gas emissions -- aka they should NOT be used as offsets.

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.

@bstorrow I wonder how much of this is due to prevailing wage and apprenticeship requirements needed to reach max-value PTC. If there is a bottleneck there, I'm sure it's worthwhile for wind/solar developers to delay projects until those labor standards can be met

U.S. renewable growth slowed markedly in Q3. Country installed two - TWO- onshore wind farms. And relatively small ones at that. Question is whether it is a temporary slowdown or reflective of longer-term challenges subscriber.politicopro.com/article/eenews…

@davidrvetter If only there was a field in economics that did explicitly consider the environment and natural resources and they had an association with 100s of members and some respected journals and conferences…oh wait that does all exist. @AereOrg. Look into it.

On Monday, we [the MSEE cohort at @TheSmithSchool, @UniofOxford] met visionary systems thinker @KateRaworth and spoke with her about reimagining what and who the economy is for. Yet you won't hear her thesis in a mainstream economics lecture. 🧵 1/16

@JesseJenkins Yes makes sense. I was thinking in terms of discrete decisions planners might have. So maybe $60/ton vs NG and $25 vs coal (for the full $25/MWh credit)

Anyone want to correct my rough math here? The incentive from a $25/MWh production tax credit for carbon-free electricity generation is equivalent to a $61/tonne carbon price on electricity from natural gas. ($25/MWh divided by 0.41 tonnes/MWh).

@joshdr83 @OctaviSemonin @duncancampbell Sort of deregulation, but difference b/w utility and ipp additions weren't huge (66.8 GW of ngcc for utility and 74.1 for IPP over 2000-2005). The additions of gas were almost all NGCC. I thought it was in part due to tech improvements.

It's kind of incredible how much natural gas generation capacity was installed in the early 2000's. I feel like I should know this, but what drove that?

@JesseJenkins @noahqk Might be politically more feasible to sequence big subsidy then binding emissions constraint, but doesn’t it just shift the cost burden? Would be interesting to explore if that burden shift is progressive or regressive

@noahqk Let's keep working on that... But I do think this is the sequence that works. Make clean energy cheap. Then cost uncertainty looks more manageable to interests and politics of emissions cap might shift. Let's test that theory out eh?

For times like this, it'd be nice to have a climate change law that makes emissions targets mandatory. Then, the uncertainty would shift from emissions to costs. Probably better policy sequencing.

@robbieorvis Interesting that this analysis shows very little transportation sector reductions and much larger elec. sector reductions compared to REPEAT, but similar overall reductions to REPEAT. Is this simply due to lower overall elec. demand given lower EV adoption in your model?

🚨Updated IRA Modeling🚨 1⃣ Today we (@EnergyInnovLLC) released updated modeling of the IRA. We updated our modeling to reflect final bill text, add new modeling projections and data, incorporate new modeling updates. Results below. Text here: energyinnovation.org/wp-content/upl…

@RobGramlichDC There are many papers on restructuring in the economics literature. Fewer of late as we learn more about the limits of identification from methods that exploit restructuring as a quasi natural experiment. Still many many IO econ papers applied to power sector coming out

Completely agree with this. Technology has changed, the questions are as or more important than then (I would say'95-'10), but academic research on restructuring and IO economics applied to the power sector has all but disappeared. Let's petition the American Economics Assoc.
Travis Fisher@ts_fisher

One thing I’m having trouble understanding is why so many regulators and academics cared about studying restructuring in 2008/2009 but have gone completely silent since then. Any ideas? #energytwitter #electricity #competition

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
Tyler Norris@tylerhnorris

Actual line from testimony just filed by 2nd largest US utility: “accelerating solar deployments based on today’s tech could crowd out future, unknown solar or other technologies that are more efficient or more cost-effective than today’s solar.” Not the Onion, folks.
