If CO2 emissions go to zero in 2050 (top), the sinks (green) will bring atmospheric CO2 back down (middle), & temperature will stabalise at ~1.7°C (bottom).

Going to zero today will keep us <1.5°C

Constant emissions leads to 2.6°C, rising rapidly thereafter.

A large SUV with private jet wings

A group of campaigners holding "Tax Private Jets" signs.

Did you know you pay more fuel tax on a single car journey than a billionaire does on a private jet flight?

Right now the gov is subsidising tax breaks, when they could be using that tax to generate billions for public services.

Table of COP data from PassivSystems MMSP dashboard for 2025 so far

ASHP stats Oct-2025 (via MMSP)
Elec consump = 153kWh of which
DHW = 16kWh, SH = 133kWh
total heat delivered = 605kWh
Overall COP = 3.96
COP space heat = 4.28
COP hot water = 2.32
Average flow temp = 31.0°C
Outside temp = 11.1°C
Room temp = 19.3°C
Power draw SH = 409W
Power draw DHW = 1.42kW

We used 290.4kWh of grid⚡ in Oct-2025 with
~7kWh for EV
181kWh general household activity
153.8kWh for ASHP
Delivering 605kWh heat & DHW
our PV generated 103kWh, with 101kWh self consump & ~2kWh export
Total cost of elec: £64.62 inc VAT and standing charge (but excluding FiT payments for our PV).

How many....?

Our charge point is located off a single track back alley and we are in the middle of the street. So we often blocked out of our own charge point. So yeah, we do very few miles and I have had to use public charge points 2 or 3 times during Oct.

Really happy to have Home Assistant up & running on this Pi5 with NVMe drive. This is an upgrade from previous Pi4 with SD card. Thanks to Matt & Ellis at Carbon.Coop for help restoring backup file of Home Assistant instance. All working very smoothly.

The winderful.uk dashboard showing that wind is generating 15,917 MW. That's enough to power 13,264,167 toasters!

While you were sleeping, #windEnergy reached 64% of the National Grid's electricity demand. https://winderful.uk

Thanks - amended that now.

No, you aren’t imagining it: the Tube is getting louder I SAID, THE TUBE *IS* GETTING LOUDER.

The main cause of the noise is something that will, sooner or later, hit every part of the network: “rail corrugation”.

You aren’t imagining it: London's Tube is getting louder.

3. Main takeaways, continued:
- Retail electricity prices, and price increases, are mostly about spending on poles and wires, not energy supply
- Renewables don't correlate with higher prices, but dependence on natural gas pretty clearly does

Russia’s Coal Collapse Marks The End Of Fossil Fuel Post-War Illusion Russia’s Coal Collapse signals the end of the fossil era. From bankrupt mines to battery booms, the global energy transition is accelerating. Facing political resistance.

Britain missing out on potential £2bn recycling industry by exporting plastic waste Exclusive: Government failure to close loophole allows 600,000 tonnes to be shipped elsewhere each year

Oh and www.theguardian.com/environment/...

UK plastic waste exports to developing countries rose 84% in a year, data shows Campaigners say increase in exports mostly to Malaysia and Indonesia is ‘unethical and irresponsible waste imperialism’

Brexit "dividend" here, UK plastic waste (imperialism) exports to developing countries rose 84% in a year, data shows www.theguardian.com/environment/...

In the first half of 2025, renewables became the biggest source of global electricity for the first time, as wind & solar growth exceeded global demand growth

Shocking that it's China & India leading - EU & USA have fossil power growing

Cottam coal power station demolished today (the cooling towers).

Will be replaced by a solar farm, using the same grid connection.

Oh and 3) our 19yo lad being away at Uni or on holiday etc meaning DHW is generally 1/2 while he's away.

Visible change caused by 1) sunny (spring-summer)period where our DHW has a lot of PV divert into HW storage 2) minor change to HP control strategy with HomeAssistant now taking control of DHW priority, this from July on.

High-speed rail is coming to #Canada!

This week, federal government fast-tracked the Alto project.

Will link #Quebec City- #Montreal - #Ottawa - #Toronto , a corridor with half Canada's population.

Projected to carry 30 million passengers a year—twice US Northeast Corridor—on 300 km/h trains.

He headlined a $500 dollar a head fundraiser for Trump…

I doubt, in those circumstances, he funded the trip (air fares/ hotels etc) himself

He‘s acting like a foreign agent isn’t he?

If he loves Trump’s America so much, why doesn’t he go & lives there? …the Brexiter’s line to Pro Eu people.

You're really going for it!!

Imagine a grid able to understand actual demand for a day based on heatpumps telling it what they need and cars telling it what they need. It could balance load by staggering car chargers and staggering hot water loads.
