HAPPENING NOW: #RFFlive’s “Making Sense of @FERC’s #MOPR Order.” Watch the livestream on our event webpage:

#EnergyTwitter #FutureOfPower
@FERC 2/ RFF’s Kathryne Cleary is giving a brief primer on @FERC’s #MOPR order. Some context: @pjminterconnect’s capacity market, which we’re here to discuss today, is intended to promote investment and ensure adequate supply is available to meet demand.
@FERC @pjminterconnect 3/ Cleary: PJM has had an existing #MOPR in place since 2006, which was originally intended for new #NatGas plants to prevent them from bidding into the market at low prices. This MOPR order expands upon that to include state-subsidized resources.

It's 8:53 PM on the East Coast and I am deeply disappointed that I have reached the end of the rehearing requests available on eLibrary. The bulk of today's filings are apparently stuck...somewhere?
Filing of the day in the PJM capacity docket is clearly:

Out-of-Time Motion to Invervene of The Hershey Company under EL16-49, et. al.
One #EnergyTwitter hero has stepped up and emailed me their filing. Thank you. Are there other heroes on this social media platform at 9:21 on a Tuesday evening?

#EnergyTwitter, do I want to attend my first ever SEJ conference in September, in Boise, ID? Y/N
The problem is, Future Me always wants to attend events and give talks. They sound fun for Future Me! But then, when the time comes, Future Me is nowhere to be found, only Present Me, who hates work travel & prefers being lazy. Where's Future Me when you need him?
All right, all right, y'all have talked me (or at least Future Me) into it. Boise it is.

#energytwitter New #Businessmodels for #EU prosumers! Local energy trading and self consumption in EU nations. @Proseu_Project @BrownSdc @BaumanInstitute
Disappearing subsidies are driving #innovation across decentralised generation. New ways of trading and sharing local electricity are coming @NewAngliaEnergy @exeterepg @Comm1nrg @Regen_insight @EnergyREV_UK @EnergySysCat @NatureEnergyJnl @energycities @Bankfieldbecky
Extending the definition of 'self' consumption to neighbourhoods and communities can really improve the viability of decentralised generation. This #p2p model is one way, but we think that micro trades can make local energy projects too 'markets' focussed. I.e. not fun 😑

Today @RockyMtnInst has released our foundational analysis to understand The Impact of Fossil Fuels in Buildings. Direct combustion in homes and businesses has been ~10% of GHG emissions for decades, with impacts on climate, health, & infrastructure. #energytwitter #climatechange
Across the US economy, gas has now surpassed coal in its overall contribution to climate change. With coal’s decline, electric power-sector emissions have fallen by a quarter in the past decade, but emissions from fuels burned in buildings have not budged.
The majority of these emissions are the result of burning gas (about 450 million tons of CO2 per year), with propane (78 million tons) and heating oil (64 million tons) still producing significant emissions.

THREAD (1/16)

What Will It Take to Clean Up the Electric Grid?
It's a huge undertaking to slow climate change, but we've done big things before.

The latest from me and @JustinHGillis in the @nytimes:…
(2/16) #energytwitter is out there sharpening pencils to check our math as we speak. So here's some help.

We used the Energy Policy Simulator ( to look at a scenario that hits ~90% clean by 2030. "Net zero" by 2030 could include offsets for the last ~10%
(3/16) "Clean" is defined as anything that produces electricity without emitting GHGs.

In practice, hitting ~90% means all coal would retire, some existing gas would hang around to be used for flexibility, while hydro, nuclear, and other renewables would generate the rest.

Happy Holidays #energytwitter! Reading children's Christmas books to my toddler has put me in that mood again. With apologies in advance for the questionable meter and rhyming, please enjoy "How The Grinch Stole Clean Energy... And Then Gave It Back" [Thread]
A long time ago (and, in places, still now),
A grumpy old Grinch hadn't figured out how
To meet all the Whos’ clean power desires,
Instead of just lighting old carbon on fire.
So this is a tale of the Grinch's transition,
And the power to change once he stopped to listen...
Every Who down in Whoville liked clean energy, lots
But the old Grinch who sold them their power did NOT
The Grinch hated green stuff; he preferred burning
Fossilized carbon to keep turbines turning

Hey #EnergyTwitter….here’s a thread on the electrification of oil and gas. #oilandgas #electrificationofeverything /START
There’s been a lot of chatter about “electrification of everything” as a way to tackle climate change & re-invent our energy system. One part of this electrification trend that receives less attention is the electrification of oil and gas./1
There are many motivations for the extractive industries sector to electrify. And that electrification shows up in multiple ways./2

I recently spent some time digging into cement & concrete emissions, and they are FASCINATING

(apologies to all my friends who’ve had to hear about this at length)
#climatetwitter #energytwitter
I should mention that I used to be a little obsessed with cement and concrete — I grew up next to a cement plant and won my school’s science fair with a project on strengths of different types of concrete — but I didn’t realize just how big their impact is
The current form of cement, Portland Cement, is the most common man-made material on the planet and it basically hasn’t changed at all in 200+ years

There have been some great threads over the weekend about what makes #climatetwitter and #energytwitter productive spaces, and what makes them less so. You'll find some those threads, if you haven't already, from @leahstokes, @DoctorVive, & @LetsFishSmarter and probably others.
I've been thinking about how the less productive moments I've seen fit on here, are pretty similar to the common difficulties people have communicating with each other about complex systems.
#1 - Sometimes people are describing different sub-systems of the same system. Very old wisdom traditions teach about this, like the Indian parable of the 'blind man and the elephant. Here's the version from wikipedia:

1/ Thread on the coming internal combustion engine death spiral (which needs a better name). A hypothesis..
2/ #energytwitter talks a lot about the utility death spiral. Still a theory - I think - as most utilities who haven't set their state on fire seem to still be doing pretty well. Shouldn't we expect the same kind of thing to happen in the internal combustion engine value chain?
3/ Imagine a scenario where a substantial percentage of internal combustion vehicles are replaced by #EVs. Doesn't even have to be that big of a percentage.. Maybe 30%? Which Bloomberg thinks will happen globally around 2040?…

#energytwitter @exeterepg @EnergySysCat @EnergyLeeds @EnergyREV_UK @NatureEnergyJnl continuing our energy #ideology theme for the week, we know ideology is a fundamental determinant of whether and if we legislate for an #energytransition…
So overt questions of regulating energy in capitalism are legit terrain for a partisan empirics of energy research. But are we aware how much we enjoy our own more private ideologies? Reactions to @UKLabour energy policy are fascinating.

I've been thinking about the debate over making utilities/power systems public.

First off, I salute the Sanders Campaign and @DemSocialists for getting this in the public debate. It's not the first time they've changed the Overton Window, and I think we all benefit. /1(thread)
@DemSocialists That said, I have a disagreement with this idea, but it isn't because I oppose making utilities public. It's because I (and many of us on #energytwitter) have different priorities.

Many of us feel we need to change the structure of the power system / break up utilities. /2
@DemSocialists And we have pretty specific ideas about what is wrong with the current model of utilities & regulation - both for public and private utilities. There are some structures that are really in the way of decarbonization, and they don't get fixed by merely making utilities public. /3

#EnergyTwitter, I'm writing a post about the PG&E mess in California. One question I'm having a weirdly difficult time finding answers to: what is the solution? What are the options to reduce the threat going forward? Is there even a plausible plan?
This thread is awesome and so informative! Y'all are the best.

One follow-up question: I got some people confidently telling me that burying transmission lines is part of the answer & some people confidently telling me it's impossible in CA. So which is it y'all?
Welp, I've now got enough reading material on PG&E, wildfires, and the grid to keep me busy until [checks watch] forever.

🚨New paper alert!🚨#energytwitter
In the absence of a price on carbon, the operation of grid-scale energy storage tends to increase GHG emissions, not decrease them. We propose a market rule to mitigate this effect: an Emissions Neutrality Constraint.…
First, why does energy storage tend to increase GHG emissions? Plenty of work has already been done on this topic (see R. Sioshansi and @ElephantEating for some examples), but the gist is that it's most profitable to charge with coal power and discharge to displace natural gas.
As the penetration of renewables increases, this negative effect will decrease and eventually flip (see the work of @TheEnergyCraig), but for now the beneficial effect of soaking up excess renewables is outweighed by the negative effect of coal->gas fuel switching.

PJM's 10-hour duration requirement doesn't pass the sniff test when you look at how the system actually operates on the most challenging peak days - a thread
Some background: PJM has proposed that a resource can only get paid from the capacity market if it can inject over 10 continuous hours. So if you build a 100 MW energy storage system w/ 4 hour duration, your check will be 40% of the check sent to the owner of a 100 MW gas peaker.
PJM is an outlier. Every other ISO/RTO with a capacity market gives full, or nearly full, credit if you can dispatch for 4 hours. But PJM has argued that their peaks are 10 hours long, and so they need 10 hour dispatches to maintain a reliable system.

#EnergyTwitter! The folks at @thetroublemag are putting together a package of stories on nationalizing utilities. They've got some Pro writers; they need a few Anti perspectives. Hit them up if you're against it.
@thetroublemag I'm going to do a deeper dive on this later, but my impression is that, while the pro-nationalization perspective is ideological, the Anti is more pragmatic: it's a huge expenditure of political capital that's basically orthogonal to the goal of decarbonization.
@thetroublemag That said I don't have particularly strong or settled views on it and look forward to reading what smart people have to say.

1/ Clean energy thread time:

Yesterday the #Hydrogen Study for British Columbia was released. The Study makes a compelling case for clean H2 to achieve its 2050 GHG reduction targets…

#bcpoli #climate #energytwitter
2/ Interest in #hydrogen as a clean energy source has gone through peaks and valleys over the past 30 years. But, this time is different. The role for H2 is critical as a low-carbon energy carrier to address difficult to decarbonize end-uses.
3/ The promise of #hydrogen in the province is summarized nicely:

mini-THREAD on a new debate between @KevinClimate and myself in @nature's @NatureNV column on the role of integrated assessment models (IAMs) in #climate strategies which inform much of @IPCC_CH recommendations. #climatetwitter #energytwitter 1/3
.@KevinClimate argues IAMs accelerate climate policy failure by promoting technocratic solutions & detracting attention from necessary social change. I respond that IAMs are indispensable to analyse driving forces of climate change & the scale of transformations needed 2/3
Both technocratic and social solutions can be represented in IAMs, but whether it is more feasible to deploy massive negative emissions or to radically change lifestyles should be established by disciplines other than IAMs. 3/3

🚨 Thread on rooftop solar & net metering! 🚨

This past week @mitenergy published a podcast in which we discuss the economics of rooftop solar, and, in particular, issues related to equity, net metering, & rooftop PV.

See the podcast below, & check out this thread for more!
Before I dive in, I want to note that many of the findings in this thread are early & stem from my PhD dissertation. I'm hoping that the #EnergyTwitter hivemind will provide feedback to improve the work. Please don't hesitate to *constructively* criticize. That's why I'm here!
As #Democratic presidential candidates lay out their climate plans, many have put clean power and justice at the core of their policies.

In my PhD dissertation, I dove into one energy justice issue: How does rooftop solar adoption and rate design impact vulnerable communities?

1/ Okay #climatetwitter and #energytwitter. Today I've been compiling a list of the top models I used for energy analysis. I figured I would make this publicly available as a resource for other folks, and to hear about what I'm missing.
2/ First a shameless plug for our (@EnergyInnovLLC) free model, the Energy Policy Simulator. The EPS covers 8 regions (US, China, India, Mexico, Indonesia, Canada, Poland, and KSA) and forecasts how policies affect energy, emissions, and cash flows.
3/ Next, work by others A-Z:

Hey #EnergyTwitter, I'm going to write about this stupid Ohio bill. If you have any thoughts on it (or good links), do share.…
This Ohio bill is unbelievable. So many sordid details. But here's my favorite sentence I've read so far in coverage: "FirstEnergy first revealed a year ago that the energy efficiency rules were interfering with normal market growth."
To translate: energy efficiency is causing FirstEnergy customers to reduce their energy consumption, and FirstEnergy is pitching that (to policymakers!) as a *problem*. It only profits if customers use more, more, more. Lord the utility sector is f'd up.

#EnergyTwitter, Please Retweet:

Announcing a new video series to introduce 35 inventions and an implementation plan for an emissions-free planet.

#ThermalHydrogen uses teamwork to provide emissions free heat and ions, pumped.

The premise of #ThermalHydrogen is that all energy suppliers--renewable, nuclear, and fossil--have unique strengths & weaknesses.

Through #teamwork, the strengths can be harnessed.

This thread previews the basic concepts, an outline for implementation, and a new company.
Key insight #1 of #ThermalHydrogen is that electrolyser/fuel cells can also filter oxygen.

This pure O2 allows fossil fuels to become more efficient and pre-empt Carbon Capture.

Therefore, it allows a path where fossil fuels can be increasingly competitive and emissions free.
