YouTube video by The Independent Resurfaced clip shows Trump accusing Obama of wanting a war with Iran

"Our president will start a war with Iran because he has absolutely no ability to negotiate. He's weak and he's ineffective."

In other words, Trump’s mandate is not what he and some others think it is. It is in fact much, much narrower. Also, he is failing it.

Opinion | The Great Capitulation Is Over. What Will Take Its Place?

Reason for hope:

β€œThe 2024 elections weren’t a tectonic social and cultural shift. They were not about rejecting the Enlightenment; they were a complaint about the cost of ground beef. Voters were not embracing patriarchal dictatorshipβ€œ.

An important and underappreciated fact of electricity economics: The US average *wholesale* electricity price is ~5 c/kWh, or ~25% of the average *retail* price of ~19 c/kWh. The other ~75% of the electricity prices we pay is about poles, wires, transformers, generation capacity, and utility profit.

British wind farms drive down day-ahead wholesale energy prices by almost a third in 2025 British wind farms helped limit the role of gas power plants in setting prices, cutting power prices by almost a third, according to new analysis.

β€˜Great Britain’s day-ahead wholesale prices in 2024 could have been up to 33 per cent higher had there been no large-scale wind capacity…around Β£83/MWh, but could have been as high as Β£121/MWh…has over 29 GW of operational wind capacity’

We’re just not a free country.

Any American watching this play out between regime forces and journalists overseas would recognize it for what it is.

Mulling it over, while it's true that ICE's actions are against core American values we should all be able to agree on, the Gadsden flag words may raise unhelpful connotations.

Good point. Here the approach was top-down and we fitted an S curve. This does capture the network effects at the beginning where they act as a brake, but is in contradiction at the end (where the ICE phase out slows down rather than speeds up).

In our case we are not using consumer electronics as a reference class and I agree that would be an inaccurate analogy.

The point here is that what matters for emissions is how many miles are being driven in clean vehicles. A closely related proxy for this is how many of of the total vehicles on the road are clean; i.e. the share of EVs in the "fleet". The problem we face is that the fleet turns over very slowly.

This is driven by the turnover lag, illustrated here:

Good news about EV sales below. But bad news is that we are far off target given the current pace of vehicle turnover:

A Merriam-Webster dictionary screenshot of the definition of fascism, which reads: "a populist political philosophy, movement, or regime (such as that of the Fascisti) that exalts nation and often race above the individual, that is associated with a centralized autocratic government headed by a dictatorial leader, and that is characterized by severe economic and social regimentation and by forcible suppression of opposition"

Gee golly, that sounds familiar.
