🚨Vehicle Registration Data for 2025 🚨

December stats are extraordinary with Electric Cars taking 32.2% market share.
Petrol registrations plummet below 40% market share for the first time and diesel falls to 4.2% of all new registrations.
Hybrids and plug-in hybrids rise as expected.

Petrol market share has fallen below 50% for the year at 46.4% with electric cars climbing to 23.9% market share for the year.
The 28% ZEV mandate target for EVs in 2025 should have been met when Government flexibilities are taken into account.

@NathanpmYoung I think I’d fit into the mainstream leftism and Christianity spheres, needs extending at the top!

@MichaelRWear I shall have a look!

@ember_energy Thanks for sharing the video! Love your work and am inspired by the data you share

More solar was installed globally in first 4 months of 2025 than in all of 2022!

New battery storage is also setting global records in 2025.

Wind too likely sets a new global record for deployment in 2025.

EVs have record sales in 2025.

Petrostate politicos freak out.

Thanks to @tom_bray for this excellent video about @Openenergymon HeatPumpMonitor 😀 👏https://t.co/f5CwrtA8pr

@dc_lawrence Although I broadly agree with what you are saying…. Air to air heat pumps will get us part way in heat decarbonisation. Often only serving 1/2 rooms, and not providing hot water.

They can help reduce gas demand, but not the whole solution.

Drax widened its lead as the UK’s largest single source of carbon emissions in 2024, increasing its CO2 pollution by 16%.

Despite subsidy cuts from 2027 onwards, public funds for biomass will likely ensure Drax is STILL the UK’s largest emitter in 2030.

@ecocars1 Fantastic, and imagine the impact that has had in helping people understand the low carbon transition for themselves! People who have got EVs / solar / batteries because of your videos!

@mwt2008 Charging the car, heating water, even put heat pump back on here in the North East because of this (and negative octopus agile tariffs!)
