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

1/n
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 >

1/n

#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?

2/n
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: caiso.com/TodaysOutlook/…
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!).
Turns out its all hidden here in excel form: caiso.com/informed/Pages…

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 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
thewalrus.ca/the-accidental…
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.

THREAD
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.
forms.gle/oUYEnpHUe1nLuD…
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...
...solutions 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: youtube.com/playlist?list=…
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): energy101.com

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: buff.ly/2NjS9g3

#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
@https://proseu.eu/sites/default/files/Resources/PROSEU_D4.1_Business%20models%20for%20collective%20prosumers.pdf
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: nytimes.com/2019/12/16/opi…
(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 (us.energypolicy.solutions) 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? about.bnef.com/electric-vehic…

#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 sciencedirect.com/science/articl…
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

🚨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.
ieeexplore.ieee.org/document/88448…
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.
