District heating in the UK contributes only 2% to heat demand and >90% is fossil fuel based.

By 2050 district heating could contribute 20% to UK heat demand. Modelling for the Climate Change Committee identifies heat pumps using excess and ambient heat as key technologies for decarbonisation.

If you do one good Nerd Thing this week, make it tapping the 'I Don't Need a Refund' button in Tweetbot and Twitterrific.

These apps, in many ways, pioneered the modern concept of quality, indie app for iPhone. They gave us much more than they ever asked for with their subscriptions.

A Final Update to Tweetbot and Twitterrific That Allows Users to Support Tapbots and The Iconfactory

Usually, when a big company shuts down an API, they give customers time to prepare. It’s the right thing to do regardless of what any terms of service say. That’s not how things went down with Twitter. Instead, as I wrote in January, Twitter eliminated access to its API for many third-party apps, including Tweetbot

If you were a former paying customer of Tweetbot or Twitterrific who was happy with what they got out of the app before Twitter unceremoniously killed third-party clients, then consider launching the latest update and opting out of the refund. The money comes out of the developer's pockets, and the fact that the apps don't work anymore isn't really their fault—you can ease the load on them a bit. https://sixcolors.com/post/2023/03/tweetbot-and-twitterrific-updated-with-option-to-opt-out-of-subscription-refund/

When Twitter shut down third-party clients in January, it not only left out in the cold the users of those apps, but the developers too. Many of those apps were significant sources of revenue for t…

#energytwitter / #energymastodon help! I'd planned to get a heat pump soon, but my boiler was declared dead this weekend and it's cold!

I've spoken to 2 engineers and filled in loads of online forms: seems I can get a boiler tomorrow but a heat pump in 6 weeks. Really?

I've tested radiators at 50c flow temp this Dec, modelled building heat loss at ~5-6kW, know I have a 100A fuse+fat enough pipes. But I'm not a heat engineer/MCS certified and am bad at plumbing.

Anyone fancy a challenge?

The APIs that Twitter/Mastodon migration tools use are being shutoff in a few days, so if you haven't scraped your followers from there yet you may want to do so now.

“Hey folks, even if you're not planning on using Mastodon instantly, you should take some time this week to create an account and set up your follows. Twitter is starting to charge for API access to the migration tools in 5 days, meaning the migration tools will probably break.”

Guest post: How the UK’s push to reach net-zero could deliver key health benefits - Carbon Brief

The IPCC's most recent assessment of climate impacts concluded that global warming “has adversely affected physical health of people globally”.

Carbon Brief

We’ve prepared this summary to meet the regular requests we receive from other parts of the world, but it’s a very accessible guide for anyone in the UK too.

We’ll be reviewing this method as we plan for Carbon Budget 7.

How does the Climate Change Committee build our recommended path to Net Zero for the UK?

This is a new guide to how we determine a sector-by-sector pathway - the pace of emissions reduction that can be achieved, the trade-offs, implications and constraints involved in the transition.
