Never mind the miracle cells, just give us cheap perovskite with a decent life expectancy #energysky

No, it's not. It's just what it says.

That lever marked "cut energy bills":

- Locational Marginal Pricing
- move policy costs from elec to taxation
- tax fossil fuel industries more; subsidise energy efficiency & elec standing charges
- single state purchaser for electricity: break the link between wholesale elec price & gas price

It's the best single indicator of whether the room ventilation is sufficient when occupied. Levels above a few hundred ppm are enough to diminish thinking.

If you wait by the river long enough, you will see... well, not a dam floating past, that's exactly the opposite of what should happen with a dam.

If we want it built, some of us are gonna have to go make it happen.

It's been proposed as a key part of a #supergrid for 20+ years

It would be a source of power & balancing at a wide range of timescales for a vast area. #GregorCzischWasRight

& there is hope that an Africa united in trade and mutual inter-dependence could move to a new era of unity & prosperity

And *that* is why parking maximums and parking-space taxes are necessary

Enormous potential, for renewables, rewilding, rainforest, rewetted wetlands.

But the public discourse is impoverished, despite the best efforts of a handful of heroes: @hannahdaly.bsky.social @peterthorne.bsky.social @caugustenborg.bsky.social @thinkorswim.bsky.social @irishrainforest.bsky.social

Hi, I guess I'm kind of active. Well, by my own benchmark, at least.

The government's Climate Change Advisory Council were briefed by experts that new data centres would make it very difficult to meet the carbon budgets.

Industry lobbyists span a different story.

Lobbyists carry more weight than experts.

It's profoundly upsetting, frustrating & insulting.

And GB is absolutely going to need heat networks at huge scale, probably 40-50% of dwellings. It would be absurd not to. It's crucial to take a systems-level view here: optimising for one dwelling and then scaling that solution to national level is doomed.

There's been 30 years of research on how to do policy evaluation, since then. Plus a slowly growing realisation that England isn't anywhere near as exceptional as it likes to think it is. And a better understanding of how to (re)shape institutional cultures.

GB *can* do what Denmark did, which is build local capacity in local not-for-profit delivery bodies.

If GB chose to be smart about it, it could buy in expertise from DK and other successful places, to bring their corporate culture & processes.

Or it could reinvent the wheel.

I thought for one wonderful moment that Britain was going to break from decades of stupidity, and you were going to say: we studied countries that have been doing this well for decades, and decided to copy that exactly.

Yes, those emissions are largely from manufacturing. As manufacturing, freight transport & concrete decarbonise, those trend to zero.
There is no 1 "actual" number: there are credible ranges, which steadily as economies decarbonise.

These cables aren't for net imports. They're primarily for balancing services.

Intercontinental transmission can significantly reduce the need for local long-duration storage at both ends, and is one of the cheapest ways to do that.

yeah, if you've got (half-) empty carriages, make those seats cheaper. That should be sensible train business, and good transport planning. There's been a reluctance in many countries to do more yield management, to avoid complex pricing. But that doesn't seem to do much harm to planes & hotels.

there's related research @ketanjoshi.co @nworbmot.bsky.social from David Brayshaw.
