Just in general in most cities and countries, or did you have a particular city or country that you wanted your readers to be thinking about in this chat that needs to happen?

In my work these days, I'm frequently reminded of that inspirational JFK quote:

"We do these things not because they are easy,
but because we thought they would be easy"

What I like about this judgment shortcut is that it dispenses with the onerous step of reading what is admittedly a very long book :)

Ah, right. Sounds like a particularly stupid version of guilt by association. β€œDon’t judge a book by (stereotypical associations you might have about) its owners.”

But I’m a fan of DFW and IJ, so I’ve probably already disqualified myself as being that guy. :)

Bad reputation why?

In about 1990 in Chicago, I was in a bank teller line and Billy Corgan came to say hi to the woman in front of me in line, who he knew. She asked how he was doing, and he said β€œHey, really good, I just got a record deal.” She said β€œoh, that’s great”

Lately we've realized that hist texts to us have been written by ChatGPT or similar. They are effective (just conversations about schedule), but with startling length, fluency, vocabulary, and good cheer

I’ve always been a fan of RZA and GZA. SZA not so much.

Uh, isn't leftist a relative term just like centrist? Aren't you still defining yourself relative to the room you're in? Left of what?

I put the original post in the very popular posting category called Reasons Why People Who Disagree With Me Somewhat Are Not Only Incorrect But Actually Evil

Nah. It can result from assessing your own true beliefs, then looking around the room and noticing that you’re not standing at either edge of the room, then using that one word as a super-concise summary to make it easier for others to roughly locate you

Electric Power Monthly - U.S. Energy Information Administration (EIA)

Bad news for solar today

To my surprise, EIA projects there were will be *less* new utility-scale solar capacity added in the U.S. in the next 12 months than in the prev 12 months. What's up with that?

(See the Solar subtotal row of the Jan 25 - Feb 25 report

Sure. Which is why you see all these β€œNatural gas drives out coal!” posts with graphs that omit wind and solar … but you don’t. There’s enough real success in renewables to celebrate without this kind of misleading presentation

22.04.2025 01:45 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Why do graphs like this so often leave out natural gas?

Natural gas is more responsible for the decline of coal than wind and solar are

Negative prices in CAISO: What PPA buyers and renewable developers need to know The last few years have seen an increasing trend of negative power prices in the region served by CAISO, particularly in Southern California.

See this piece on negative prices: www.renewableenergyworld.com/solar/negati...

Disconnection of renewables source is not that straightforward.

Also, renewables can beat fossil sources on cost in many situations, but not by so much that they still win if you have to discard most of the power

Thanks for the reply. I think you're underestimating the grid operational challenges of solar intermittency and oversupply.

Again: why do negative energy prices exist? Is it because no one had the sense to go out and disconnect the panels for a bit?

Hmm, maybe we should switch languages. Have you heard the Latin phrase β€œnon sequitur”

English grew up in England, and lived there for several hundred years. But when it came time to put away childish things it grew up and moved out. Soon it was spoken by many more people than those it had left behind, and it even became big in Japan!

But returning to the metrics question: even in a waterworks world, it would be weird to choose a metric to focus on that celebrated how much extra water you produced during peak flood times. Instead, you'd want to focus on how much you have in the dry times, or how infrequent dry times are

Negative prices require that it's even possible to deliver the power. Curtailment happens when the excess power can't even be put into transmission lines without damage or instability

Why not just let the electrons spill out over the top of the wire onto the ground? Because electricity is not water

:)

Grids and waterworks are not analogous

When you build a waterworks you don't have to pay someone to accept your excess water when you have too much

In your analogy, why are negative power prices a thing?
