@mygridgb.bsky.social has this excellent UK historical annual grid generation plot, that illustrates how the UK has transitioned from being dominated by Coal and Gas generation: www.mygridgb.co.uk/historicalda... Would love to see the ordered left to right from low to high gCO2/kWh sources.
The 11.7% growth is driven by strong growth in electrified cars that outstrips the shrinking share of pure fossil cars - Petrol shrinking -5.2% and Diesel -17.7% year on year. We are seeing consistent movement from pure fossil to electrified cars.
@smmt-ukauto.bsky.social have published UK car registration figures for July. Again we see really strong growth for BEV (44.5% year on year) and PHEV (33.6%).
Tesla and SpaceX stock prices are 29.73 and 32.44% down this year/since launch respectively. Has the market woken up to hype?
Over the past decades annual Grid demand ha gone down substantially an increase in population over the same period. www.mygridgb.co.uk/historicalda... Our households and businesses have all got more efficient. This gives us headroom for adding air-con, charging EVs etc.
The www.smmt.co.uk/vehicle-data... data shows solid growth for BEV, HEV and PHEV's with shrinking market share for Petrol and Diesel. One thing of note, The NewAutomotive figures for June have lower figures for Petrol and higher figures for HEV because SMMT categorize mild hybrids as Petrol.
@smmt-ukauto.bsky.social have published their UK new car registration figures for June 2026. BEV's hit 30% market share with a 35% year on year growth. BEV growth remains ahead of the S-Curve that would see 50% BEV market share in January 2028.
Individual market segments show the electrification of the UK new car market with both pure Petrol and Diesel shrinking in May and overall for the year. BEV and PHEV are the standout growth segments, with HEV managing a very modest growth.
@smmt have published their UK new car registration data for May 2026 and BEV was the fastest growing segment up 34.2% over May 2025. The pure Petrol segment shrank the most, dropping 7.1% year on year. If the market continues on its current trajectory BEVs will exceed Petrol sales in 2027.
Thanks, lots of noise with the monthly figures but with the annual figures we see a clearer signal. Sure looks like recent BEV exceed historical peaks in Petrol and Diesel sales in Norway. Must be lots of old ICE cars on the road that will need replacing soon.
Big year and year growth across the board - 24% up on April 2025. All segments grew except Diesel. The most profound market share changes is move away from pure Petrol and and Diesel, in April 2025 they totaled 54.1%, but now in April 2026 they total just 46.8%. Electrification is progressing.
@smmt-ukauto.bsky.social have published their UK new car registration data for April and 59.1% year on year growth in BEVs and 36.4% increase in PHEV are the standouts. Growth is in line with 50% BEV sales before 2028, but doesn't look like a exceptional month in this context.
Prices for new EVs have been coming down year and year so it we expected price parity with Fossil cars to happen this decade, and soon after EVs would be cheape to buy. Here in the UK we're at this point - new EVs are now cheaper than new Petrol cars: plc.autotrader.co.uk/news-views/p...
With Scotland generating so much Wind power, covering all our local demand and still having plenty to export most days of the year one, would think that electricity would be cheaper in Scotland to incentivize electrification of heating and transport. Alas, it's not. www.uswitch.com/gas-electric...
Scotland's electricity grid is 100% carbon free once again, and exporting lots of power south to support Wales and England. During our evening peak demand all electric hobs and ovens, lighting, TVs, washing machines, heat-pumps, direct electrical heating, charging of EVs etc. are all carbon free.
Even our household is generating healthy amounts of Solar. We're powering our household, including heating, from our rooftop Solar and charging household battery.
39.4% of our electricity is coming from Wind. 33.5% from Solar Just 2.8% from Gas. Living in North Scotland region I'm not surprised by the high amount of Wind - here we're most Wind powered all year round. I do find the high amount of Solar is pretty astonishing. So much progress in a short time.
A bit of sunshine and a bit of wind and the UK is now majority powered by low carbon (33g/kWh), low cost sources. carbonintensity.org.uk
The stats show year on year growth for electrified cars with 46.9% for PHEV, BEV 24.2% and 7.3% for HEV, while non electrified cars shrank 6.1% of Petrol and 11.4% for Diesel. Overall market grew 6.6% this is driven by the growth of cars with plugs.
@smmt-ukauto.bsky.social have published their UK new car registration data for March, BEV market share bumped up from 19.4 to 22.6%, this keeps the growth following the later adoption curve.
Followed the link but got the following message about needing 5 more supporters, so I guess I beat the rush... I didn't see any means for adding support, but happy to do so.
I live in North Scotland region where we already have an abundance of Wind power. This is what carbonintensity.org.uk reports on most days of the year, and ESPECIALLY in winter as that's when average wind speeds are at there highest. It's Curtailment which is our local problem.
Did you get wet? That can cause clothing issues with stuff rubbing in new and unwelcome places. You can get products to apply in areas that rub, this is what I used in my ultras.
Market share dropped for BEV, HEV, Petrol and Diesel over the past year, only PHEV grew. Despite the strong growth in PHEV the actual number of sales is half that of BEVs, and a quarter that of Petrol, and is even behind HEV is overall market share. BEV remains 2nd in market share behind Petrol.
@smmt-ukauto.bsky.social have published their UK new car registration data for Feb. 2026. BEV grew marginally (2.8%) in absolute figures vs Feb. 2025, but strong growth in PHEV (43.5%) has resulted in BEV market share dropping from 25.3% to 24.2%. I've had to adjust the S-Curves later for this.
The big winner for Jan 26 was PHEV that grew by 47.3% vs Jan 25, this brings them much closer to parity with HEVs. BEVs remain 2nd largest segment behind Petrol which shrank 1.9%. Diesel shrank even more dropping 8.8%.
@smmt-ukauto.bsky.social's UK new car registration data for January 2026 show BEV sales grew by 0.1% but as the overall market grew by 3.4% so the share shrank a little to 20.6%. This shows in the market share trends with BEV no longer ahead the later adopter curve they had been tracking.
They certainly can. Achieved a combined COP of 4.07 this week! Over 5 times better efficiency than our old combi boiler and no noxious emissions to boot.
The most noticeable market development in 2025 was the solid growth of BEV +23.9% and PHEV +34.75% segments. While HEV +7.2% saw modest growth pure Petrol -8% and Diesel -15.6% shrank. In December BEV's 32.2% closed to gap to Petrol's 39.4% share respectively vs 31 & 42.2% in 2025.
@smmt-ukauto.bsky.social have published there UK new car registrations for December 2025. Again the BEV market share peaked above the 30% market share line. Growth through 2025 stayed pretty close to the Later S-Curve, suggesting a 50% market share mid 2027.
