Energy and transitioning from fossil fuels. Complex issues I try to shine a light on. Ex-UKAEA and Met Office. @dangrey.bsky.social

Extraordinary set of charts in the FT today. Twelve years of Tory misrule has left us sicker and poorer than our peers. Utterly disastrous.

@HighwaysSWEST That's 22 miles!

.@BBCr4today we *do not* have the most expensive electricity in Europe, it's actually about average #r4today. Left is DESNZ, right is eurostat.

PLEASE start speaking truth to power and challenge any guest who says this! @bbcnickrobinson @amolrajan @BBCSimonJack @DharshiniDavid

[Dan Grey @dan_grey]

Same applies to domestic customers. GB domestic electricity was 26p/unit in first half of 2024 (average of Ofgem price caps of 28p then 24p); EU average was 24p/unit

[Dan Grey @dan_grey]

For @JustinOnWeb (and the whole @BBCr4today team); Britain does NOT have expensive energy compared to Europe. The UK is about average. Data for manufacturers from DESNZ and eurostat. #r4today

@RobertLindsay More people who give a damn about the world use blue sky than X now 🤷‍♀️

[Dan Grey @dan_grey]

@horton_official This is your semi-regular beg for you to come to blue sky because quite frankly more people interested in the environment use it than X now. By only posting here you're isolating yourself.

[Dan Grey @dan_grey]

@seb_kennedy Seb, do you fancy opening a blue sky account? I think quite a few people (myself included) no longer use X

[Dan Grey @dan_grey]

@HighwaysSWEST Is anyone on duty today? What's happening with the M5 in Devon?

[Dan Grey @dan_grey]

@JomauxJulien How are prices today, Julien?

[Dan Grey @dan_grey]

@Chris74747755 Do you fancy opening a blue sky account? (Please! 🙂)

[Dan Grey @dan_grey]

@horton_official Even if you don't leave here, it would be lovely if you could post on blue sky too

[Dan Grey @dan_grey]

@horton_official There are far more people in the environment/climate space on blue sky now. You're sorely missed! Please come over.

[Dan Grey @dan_grey]

@NerosSlacker @ionewells @WyreDavies @carolinehawley Not exactly appropriate. You might want to learn a little about some of your colleagues.

@CREACleanAir Pssst it would be great if you began using your blue sky account

Upgrading to a heat pump? Get an extra 20% off when you order before the end of the year for #PinkFriday! Discount for #Octoplus members and comes off after the government's £7,500 Boiler Upgrade Scheme grant.

[Dan Grey @dan_grey]

This.

[Dan Grey @dan_grey]

Just to expand a bit, if a heat pump is noisy, there's something wrong with it or it hasn't been installed properly. The mandatory MCS 020 noise assessment doesn't prevent that.

[Dan Grey @dan_grey]

This is deeply disappointing, as it's a) totally unnecessary bureaucracy, all heat pumps are near silent; b) unfair and discriminatory, as gas boilers are far noiser but aren't subject to noise assessment; c) undermines any benefit from removing the 1 m rule.

[Dr Matthew Aylott @renewablewriter]

@MingleDandy @Miatsf Maximum permissible noise limits will remain and all heat pumps will still need to comply with the Microgeneration Certification Scheme Noise Planning Standard MCS 020 to be eligible for installation under permitted development.

@davidevans442 Not even making this up, it’s quieter than the boiler flume was
