Yes, let’s us be serious even as they’re not. Really.

Why? The point is that RGGI is a distraction. States have pursued decarb by other means. Focus there.

Yep

My conjecture…small change on the margin, and slightly lower wholesale prices. Perhaps someone has done the study?

RGGI is almost never the relevant constraint on fossil gen, but tons of academics give it attention. Here in MA we have strict quantity caps on gas gen. But we can buy unlimited electrons from NH.

Started out as a recommendation to read. Ended as a rec not to. Hmmmmm?

I have grave doubts about the chance of being an export powerhouse that doesn’t build at home.

Same as a

Batteries on the grid…it’s all state dependent opportunity cost. Natural gas in storage, same.

Commodity markets have versions of this, but their role is limited and not as imagined here. Oil royalty trusts for example. Commodity bonds. Loans for nat gas drilling repayment schedule tied to depletion.

Both. The latter affects the former.

Thanks for flagging this. Will be fun to dig into. I have some trouble with the framing. 1. Even in systems where the cost of fuel matters, we already had problems with the energy-only design. 2. Hypothesizing flexible demand points to a world we all want but don't have. 3. Ditto storage opt.

Market annoys many people, and this is what you get.

Yes. I think the American EconomicsAssociation has shown leadership. The financial crisis of 2008 was a watershed, so if you want to say it was β€˜reactionary’, so be it. I have always been a leftist outsider. But I am willing to give respect where it’s deserved.

There is a difference between the realism of muddling through complex problems and the failed strategies of Vietnam and Afghanistan, not to mention Iraq.

It is hard to look at Afghanistan war in that lens. We stayed long after it was clear our objectives could not be met with the forces and strategy we committed. A revolving door of generals replaced
one another with a fig leaf of a new strategy.

Ok, we differ. I also think the Cold War win could benefit from a more differentiated presentation. We undermined large swaths of the decolonizing and developing world in pursuit of our win. Could have been different.

I was counting from the Vietnam war which began when I was a small child, and through Afghanistan and Iraq, and numerous smaller events. Your reply to me doesn’t acknowledge such disasters. But they have had a momentous impact on domestic affairs.

Sadly, over my 6+ decades of life, the foreign policy experts in the US have guided us into disaster after disaster, and worse still, refused to reverse obvious mistakes. Tough to make a case for expertise there. Sorry, but it’s true. We have to deal with it.

While that agent model use AI, many don’t. Best as I can tell β€˜agent’ models are engineering’s approach to reproduce economics. Just terminology that arises in a subculture.

Have you seen any papers demonstrating the value of the storage and flexibility? I haven’t.
