Utilities, including broadband, are essential services. Shareholders for ISPs, electrics, and natgas utils can/should be called on to fund services for low income & energy burdened folks. But we need to consider how rate structures contribute.
On the electric side, complicated/evolving rate structures could make energy burden worse. Adrienne Thompson has a good article here with lots of info about the issue and some potential solutions:…
Oregon's Biennial Energy report also addresses some issues of energy-burdened customers. But missing from both is a discussion of how rules against cross-subsidization make it difficult/impossible to direct ratepayer funds across classes.…

Hey #EnergyTwitter, true or false: there's no coherent physical or engineering justification for "hybrid power plants" (wind/solar/batteries); their existence is purely an artifact of perverse market structures & thus, in a sense, a sign of dysfunction.…
Main answer seems that you save on transmission/distribution costs. But you also lose something, right? The ideal wind site & the ideal solar site are not likely to be the same in all these cases.
Thanks y'all -- this is a more interesting/complicated question than I thought! (See also: all the other energy issues.) I'm not totally convinced by the savings in interconnection costs (I suspect those will decline), but the notion of distributed intelligence/coordination is 🤔

Hey #EnergyTwitter – Tulsa is in the news for many reasons. The 1921 race massacre, Trump’s rally last month, and the recent Supreme Court ruling. But Tulsa and Oklahoma are important to the history of energy and have been featured in Hollywood films. [A Thread]
If you want to read a fascinating book about how Native Americans in Oklahoma were murdered for their oil, then read “Killers of the Flower Moon”…
The Osage Murders overlapped with the birth of the FBI. The book is in development for a movie directed by Martin Scorsese @scorsesemartin and starring Leonardo Di Caprio @LeoDiCaprio and Robert De Niro…

Despite both having ~35% of electricity from renewables, the UK has cut its emissions at 3x the speed of Germany. How does that happen?

A: Margaret Thatcher, nuclear accidents, protests, economics, gas, and politics.…
Germany and the UK show how much history matters.

Both are highly industrialized and have had intentional climate policy for over a decade. But the UK has reduced its emissions at 3x the speed of Germany.

Why was the UK more successful?
From @CarbonBrief: less coal, energy efficiency, wind & solar growth, CO2 price, and gas all drove the UK's extraordinary 60%+ reduction.

But, this wasn't a secret plan that the UK kept to itself. Germany could have done this too, why didn't they?

@ShellenbergerMD wrote an opinion piece in
@Quillette with some very big claims on environment issues in order to push his new book sales. Here’s a thread on the accuracy of these claims. @EcoEye
#energytwitter #climatetwitter @gimenezbarbat @BlairKing_ca
Claim 1: “Humans are not causing a “sixth mass extinction”
False (unfortunately) - this statement completely misrepresents the view of actual scientists in the field.

“Although biologists are still debating how much the current extinction rate exceeds the background rate,
even the most conservative estimates reveal an exceptionally rapid loss of biodiversity typical of a mass extinction event.
In fact, some studies show that the interacting conditions experienced today, such as accelerated climate change, changing atmospheric composition caused

Hey #EnergyTwitter

I'm proud to present: Used But How Useful. How Electric Utilities Exploit Loopholes, Forcing Customers to Bail Out Uneconomic Coal-Fired Power Plants.

It represents the culmination of years of work on behalf of myself and my co-authors.
Thread alert 🚨 1/?
First off, I have to thank my manager at UCS (Jeff Deyette). I started analyzing the issue of uneconomic coal before I came to UCS and even though analyzing the issue wasn't in my work plan Jeff gave me the agency and autonomy to pursue this work. 2/?
Okay, now onto the juicy bits...
One of the principal shortcomings of past analyses is that they failed to account for what resources would replace coal if it wasn't dispatched. So UCS applied its considerable modeling capacity to analyze the issue.

Hi #energytwitter , this here is a THREAD about yet another worrying case of fossil fuel interests trying to influence our debate about clean energy.

It's a story about an industry lobby group that mingles with supposedly well wishing scientists and spreading IPCC denial to the youth.

So🐻 with me, your peer review is valuable.
We start off with the facts: our climate situation is so dire that @IPCC_CH calls for "all hands on deck" mobilization of all low carbon technologies, including nuclear and CCS.

"Societal preference" is certainly an obstacle, but we are running out of options. From AR5:

Reforms are coming to India's power sector. #DISCOMs in union territories are proposed to be privatized. What has India learnt from privatizing #electricity #distribution #utilities in the past?

Some food for thought >


#ElectricityTwitter #EnergyTwitter #privatization
Private/PPP DISCOMs operate in a few cities of India—most notably in #Delhi (Tata Power Delhi Distribution, #BSES Rajdhani & Yamuna), although among others, #Kolkata (CESC) and #Mumbai also receive power from privatized #DISCOMs.

What benefits accrue from #privatization?

Improvements in performance are best outcomes of #DISCOMs' #privatization—AT&C losses have fallen from 50+% in 2002 to ~8% in '19 for Delhi's DISCOMs, and CESC incurs 9.8% as against the 14.3% allowable in Kolkata.

Hi #energytwitter, where can I find historical CAISO hourly (or sub-) generation by fuel, batteries, and imports in a usable csv-type format? Essentially the data on this page but as far back as its readily available:…
I've tried going through OASIS but can't seem to find the specific fields I'm looking for (and its UI is not ideal for downloading multiple years of data!).

I'm assuming that production is exclusive of curtailment in these files (the readme is not that clear...)

Now to find 15-minute interval historical locational marginal prices back through 2014...

I have some legit questions for people who hate renewables and think they're a waste of time/money/resources/hope. Not looking to start arguments here, I'm looking to understand views
Are you arguing we should put all the money currently spent on renewables (including research, govt subsidies, etc) into research for advanced nuclear? Worth it to put the amount of clean energy in the US on hold for, at minimum, years until we have designs certified AND built?
Or should we try convincing/enticing/forcing utilities to starting build more large reactors with existing design certs NOW, like AP1000s? Or build ESBWRs, APR1400s (neither of which have been built in the US before), also putting the addition of clean energy on hold for years?

The new and mindboggling numbers on the methane emissions from the Permian Basin makes me wonder: has most of the progress to date in reducing U.S. GHG emissions been illusory, given much of it has been secured by coal-to-gas switching? #energytwitter #climatetwitter 1/n
Alvarez et al established an overall methane leakage rate for the natural gas sector at 2.3%, much higher than EPA estimates, and disturbing given that at 2.7% there is no net gain from coal-to-gas switching. 2/n
Now, with Zhang et al and Negron et al, we know that the Alvarez et al estimate is too low, and the EPA estimates are WAY too low. 3/n

The photo below reminds me of a 2013 essay by SFU economist @MarkJaccard whose 2020 book << Citizen's Guide to Climate Success: Overcoming Myths that Hinder Progress >> I recently recommended here. Allow me to excerpt a bit and explain why. THREAD
Jaccard's 2013 essay narratives Canada's bipartisan climate inaction since joining Kyoto Protocol, and culminates in his decision to risk arrest blocking a train full of coal... #energytwitter @leahstokes @KHayhoe @DKeithClimate @walrusmagazine…
The excerpt jogged from my brain by that lone undercooked bat comes in the 2nd half, where Jaccard tackles #CdnPoli-ticians' arguments against inconvenient limits on fossil fuel development.

Remember, it's 2013, and fossil-friendly Stephen Harper is Canada's prime minister ...

Ok folks its time to talk about overbuilding renewable energy as the quickest and cheapest way to a low-carbon future for Australia.

Firstly if you're thinking about both the economic recovery from the #Covid_19australia crisis and how to respond to the #climatecrisis, I highly recommend the excellent work of @Anna_Skarbek's team @ClimateWorksAus in their latest report. See @adamlmorton's article for summary
The analysis by @ClimateWorksAus "suggests over-building renewable energy to 200% capacity – double what the country needs – could be more cost-effective than building to 100%, and would spark new clean export opportunities."

Friends! I'm selling signed copies of my new book, Short Circuiting Policy, to support my local bookstore @chaucersbooks during this hard time. I've got 100 copies to sell.

Can the power of #climatetwitter + #energytwitter sell these books? LET'S DO THIS.…
Special thanks to @OUPPolitics which gave Chaucer's a great discount on the books. That means every copy you buy goes a *long* way to supporting this local bookstore. Thanks friends!
If you are wary of using a google form (note: I am the person with the information -- just me!) you can alternatively email me your shipping information and venmo me money and I will pay the store on your behalf. The details are on the Google form. Thanks!

A few thoughts on lessons learned from early in the COVID-19 pandemic [THREAD] :

1) We need universal broadband. Sending people to work from home, homeschool, etc. is only possible if everyone has reliable, high-speed access to the internet.

2) We should listen to scientists..
...when they tell us we need to get prepared for disaster ahead. Scientists have been warning us about our lack of preparedness for pandemics (and climate change) for a while.

3) Early action is cheaper and less impactful than late action. As problems compound... become more severe and costly.

4) We should use this "downtime" to make improvements to our infrastructure. The @Hyatt where I stayed used its <5% occupancy rate as an excuse to upgrade the internet access in each of its rooms. If they can...

Hey #EnergyTwitter!

Many of you are in the throes of preparing to teach your energy courses online or homeschooling. Well, it turns out I’ve spent much of the last 7 years creating a variety of online energy literacy resources, the vast preponderance of which is FREE. [THREAD]
The primary collection of online educational content I created is Energy101. We made it for a MOOC that had 40k+ students globally. It covers energy basics, fuels, sectors, & cross-cutting topics. Here are 30 video lectures; they are dated, but FREE:…
We also made an online curriculum (w/embedded quizzes for tracking progress!) as an outgrowth of that course. It costs $75-95 & has been adopted at high schools and universities (Stanford, Duke, UMD, Colorado State, UT Austin, Princeton, and Penn State):

THREAD: So, #energytwitter we did a thing. It is long testimony, but gives a pretty comprehensive look at how climate risks impact utility operations and should inform prudent planning going forward. Just a few words here on "why now?", not the merits of the case itself.
2/ Utilities like @ConEdison are now incorporating the state of the art in climate science to plan their system. Prudent planning requires this in 2020. Awareness of climate risk is here and the genie is not going back in the bottle.
3/ Corporate and investor awareness of climate risk is spiking. @blackrock and @statestreet CEO’s have strong words in the past few weeks/months re: corporations’ fiduciary duty to assess and disclose exposure to climate risk to investors.

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 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
