Re Facebook and vaccine hesitancy, this remains relevant.

Me: "If Jenny McCarthy were to put up a post saying 'don't get your kids vaccinated' would you take that down?"
Zuckerberg: "We probably would not."

facebook.com/RepSeanCasten/…
Z: "Our policy is not to ban people from posting things that are false"
Z: "Our policies against hate speech [by contrast] do lead to us taking down content completely."
Me: "Can you spread hate speech if you are an elected official?"
Z: "That depends on a bunch of specifics that I can't answer."
This matters in light of FB attacking the WH today rather than acknowledging what Zuckerberg already has: they allow lies to spread on their platform.
They have the ability to police content on their site. And they do police content on their site. Except when it affects their revenue. Hate speech and lies that drive user engagement are not more "free speechy" than those that don't. No matter what FB claims to the contrary.

So @PrattKap raises an interesting point here that relates to something I've been diving into lately. What is the value of the US balance sheet, and should we seek to maximize it? Want to (accounting) nerd out? Let's go. Thread:
1/ First, it bugs me whenever someone says "we should run the government like a business" and then says we have too many liabilities but can't quantify our assets. We own buildings, land, mineral reserves and a whole lot of other stuff, but don't quantify it. We should!
2/ And until we do, no one can make a credible argument that we have "too much" debt. Maybe we do - but you have to do the math before you can have an informed opinion. Which is to say I've been diving into that issue. #nerd

Watch FERC. Today is the last official day for my friend @FERChatterjee. Which means that President Biden has the chance to appoint a new director to arguably the most important agency in the government when it comes to near-term CO2 reduction. Gonna be a #HotFERCSummer
1/ If we are going to electrify our transportation fleet, we need a lot of new transmission (several hundred billion $ worth, according to @JesseJenkins) and >1,000 GW of new generation.
2/ Those investments will lower our cost of energy and drop CO2 emissions. But our electric regulatory structure has never been fully market-based. Federal $ (e.g., infrastructure) can close some, but not all of that gap.

OK, @NRCC. I'll bite. Let's talk about critical race theory. Buckle up and take notes. Thread:
1/ As a general matter, I don't engage with the @NRCC. They serve only to provoke and are run by people with the intellectual rigor and moral compass of an emotionally-stunted 12 year old.
2/ But this matters. They are talking about CRT not because they care about the substance. It's because they want to blow racist dog whistles at their base AND encourage parents to attack teachers. They think it will help them win elections and don't care about the cost.

I continue to think LCOE is a lousy metric to understand the power sector. But when all-in costs for clean energy are lower than marginal costs for dirty energy, it's a big deal.
This is why I've been so focused on getting our financial regulators to start planning for the massive wealth transfers that are coming to our financial system. casten.house.gov/media/press-re…
The *physical* financial risks caused by climate change (property loss, crop failures, etc) are frightening but understandable. But in the near term, the *transition* risks may be bigger.

A brief #energytwitter nerd thread. As usual, about things people aren't talking about but should be. Who should be allowed to own and profit from retail EV charging stations?
1/ That may seem a dumb question. We have a market economy, if people want this businesses will build it, right? Not so fast.
2/ Because for all the deregulation we've done of our electric markets over the past 3 decades, the "last mile" that connects to retail use is still a regulated monopoly in all 50 states.

As a general rule, I love @drvolts stuff on our energy system and almost always learn from him. But I have to quibble with this one that - like most LCOE pieces conflates capex & opex. Short thread: #energytwitter
1/ My view is that for any energy storage system *once built* the only thing that really matters is round-trip efficiency (e.g., how much electricity you get out / how much you put in). For most battery systems it's around 80%.
2/ That means that you will run that asset as long as the price you get from selling the electricity is >= 1/0.8 = 1.25x the price you paid to buy the electricity. Above that point you will make marginal money and knock any more expensive source off the grid.
