Figure shows electricity consumption throughout the day for a baseline and with an EV tariff. During the off-peak period in the middle of the night, consumption is much higher with the EV tariff, while during the peak in the early evening it is much lower.

This recent working paper by @rmetcalfe.bsky.social e.a. for @centrefornetzero.bsky.social shows how effective automated EV smart charging is:

"42% reduction in household electricity demand during peak hours, with 100% of this demand shifted to low-cost, low-emission off-peak periods."

⚑ Britain's high electricity costs aren't a net zero problem β€” they're a legacy of outdated markets designed for fossil fuels

This doesn't even make sense for like 30 reasons, there's no reason to put already-existing public data on the blockchain when it already exists and is publicly accessible, it's pretty blatantly just gonna be an attempt to pump some coin

CRISPR as a microbial immune system

In 2003, Mojica wrote the first paper suggesting that CRISPR was an innate microbial immune system. The paper was rejected by a series of high-profile journals, including Nature, Proceedings of the National Academy of Sciences, Molecular Microbiology and Nucleic Acids Research, before finally being accepted by Journal of Molecular Evolution in February, 2005.[3][4]

TIL the original paper describing CRISPR, by Francisco Mojica, was rejected by 4 journals and took 2 years to be published

I don’t think I have ever publicly criticized any Presidential nominee before.

But E.J. Antoni is completely unqualified to be BLS Commissioner. He is an extreme partisan and does not have any relevant expertise.

He would be a break from decades of nonpartisan technocrats.

EJ Antoni has never worked in statistics collection. He is 5 years out of his PhD. He's only ever written one economics paper. His explicit, only qualifications are that he works in ultra-conservative think tanks & believes Trump's conspiracies about the BLS. Grim stuff.

iolent, lawless, broken Britain? The facts tell a different story
The populist narrative of a migrant-driven crimewave is catnip on social media and oil to the wheels of Reform. But it is so far from the truth that we’re in danger of losing sight of the country we live in

Once again, another excellent article from Fraser Nelson - who, as Editor of the Spectator, did more than anyone else in the UK media class to normalise the far-right conspiracist catastrophism he now so rightly decries.

Takeaway:

Different welfare measures tell different storiesβ€”and lead to different policy conclusions depending on temperature.

The findings might sound intuitive, but they challenge some widely held views that heat pumps and heat flexibility become less useful in cold snaps.

3️⃣ Consumers save more on their bills in warmer periods (resource cost per tonne of COβ‚‚ becomes negative), but subsidies have larger welfare impacts when it's colder (larger MVPF), as heat pumps displace more carbon-intensive heating sources.

3 key insights:

1️⃣ The Coefficient of Performance (COP) averages around 3.5, but drops below 2 during the coldest winter weeks.

2️⃣ This temperature gradient is steeper than predicted by engineering modelsβ€”read the paper to explore all the reasons why.

Impact of switching to heat pumps and smart tariff on demand Our team highlight some recent revisions we've made to our heat pump working paper, which investigates impacts on energy demand using customer data, at scale.

How well do heat pumps perform in homes under different temperaturesβ€”& what does that mean for households and the grid?

Our updated paper @centrefornetzero.bsky.social reveals that heat pump efficiency varies sharply with outdoor temperature.
