A "potential" 0.43% increase in GDP by 2050 - in return for torching the UK's climate leadership and adding vast amounts of carbon to the atmosphere - is simply not worth it. No third runway. Grow the green economy, not airports. www.theguardian.com/politics/liv...

Heat pumps offer vast energy efficiency gains. They are 4x more efficient than gas boilers.

Happy new year!

What I’ve been calling “carbon leverage”: “if AI helps bring forward the electrification of heating, transport and industry by a single year, that would more than offset any negative climate impact from its own relatively limited power demand.”

Just about scraped over the 5MWh mark for the year.

39.3M GPU hours at 700 watts is 27.51 million kWh. 11390 tonnes would be about 410g/kWh, which sounds about right for the US grid. Right now, according to grid.iamkate.com, UK wind farms are generating 21GW (it’s windy), so would generate 28MWh in less than 5 seconds! (I hope my maths is right…)

Solar results are in for a dull and grey November… 110kWh total, average 3.7kWh per day. 58% of last year and 54% of the PVGIS estimate. Rubbish! Still, looks like we’re going to pay less than £50 to run the house (including the heating) AND the car once export credit from the summer is taken off.

I chatted to @chrisbaraniuk.com about thermal cameras after he tracked down one of my old tweets about an uninsulated bit of ceiling. The article is currently on the BBC News homepage. Fame at last!

Really excellent evening at the Brighton #peopleplanetpint meetup tonight. Three years to the day since the first one in Glasgow, there have now been 450 events across 120 cities. small99.co.uk/people-plane...

Arctic air slowly arriving in the south of England. Seven degree temperature drop between 5am and noon today (purple line). Heat pump now chugging along continuously, pulling about 500 watts from the battery (blue line) and pushing nearly 2000 watts of heat into the house (yellow line).

Mulling the idea of “carbon leverage”. The ability for an object or idea or process to disproportionally reduce (or, for that matter, increase) emissions far beyond the amount of carbon “invested” to create it. Example: software that controls a heat pump.

Since last posting on Bluesky, we got a heat pump. So far this month it’s cost about 1.7 pence per kWh of heat, or nearly 4 times cheaper than gas, and run entirely off our home battery or solar. Stop burning stuff!
