"Spain’s rapid renewables build-out means its power prices were set by fossil generation just 19% of the time, down from 75% in 2019. As a result, wholesale electricity was almost a third cheaper than the EU average"

Imagine having cheaper power

Spain’s Renewable-Energy Boom Loosens Gas’s Grip on Power Prices

Soaring renewables output in Spain is weakening gas’s grip on electricity prices, setting the country apart from much of Europe where fossil fuels still dictate the cost of power.

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

To borrow another example, taken from the `dbreg` README: github.com/grantmcdermo...

Here I am running a fixed-effects regression on 180 million(!) row parquet dataset... and it completes **< 2 seconds**... on my laptop 🤯

This is powered by @duckdb.org under the hood.

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.

Hinkley Point C now over £45bn. Sizewell C - which was supposed to be much cheaper based on the experiences of HP-C - now at £38bn...

Maybe, and hear me out here, new-built nuclear power is a tiny bit more expensive than renewables... 👀

Who could have known?

Jim Pickard @pickardje.bsky.social · Jul 18

when the FT revealed in January that the cost of building the Sizewell C nuclear plant had risen to around £40bn they all denied it

now we can reveal the actual price tag - to be announced this week - and it is £38bn

Ministers set to admit Sizewell C nuclear plant pricetag has soared to £38bn

New official estimate reflects surging construction inflation and contingency costs

I've written a simple guide to the new Positron IDE for #rstats and #python programming. I think that RStudio is still the most thoughtfully designed IDE for R programming but Positron is very useful if you also code a lot in Python.
