Worldwide Fossil fuel electricity generation dropped in 2025 by 0.2%, not much but the exponential growth in Renewables won't stop.

In 2026 we should see a significant drop in Fossil generation and a more rapid transformation going forward.

As the market for EVs increases and the market for Fossil cars reduces economies of scale will favour EVs.

If you are building EVs profitably then you business is likely secure, if you are trying to eeck out profit from shrinking Fossil market then you are living on borrowed time.

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:

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.

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.

With each grid scale battery storage we lower the amount of Gas we need to use for electricity generation.

While these grid scale battery deployments were planned years in advance of the US/Israeli war against Iran and subsequent Fossil fuel energy crisis, but directly reduce the impact of it.

31 consecutive days where domestic wind and solar generation covered 100 percent of national electricity demand with zero fossil fuel input at any hour of any day.

Danish grid operator Energinet confirmed it.

Feeding garden birds safely | The Wildlife Trusts Is it okay to feed our feathered friends? In light of a new evidence review from the RSPB, Tom Hibbert explains the best way to keep birds visiting your garden safe.

To feed or not to feed? That is the question currently being asked by some bird lovers. Feeding garden birds brings joy to millions of people across the UK. It can also help support birds when natural food is hard to find. www.wildlifetrusts.org/blog/tom-hib...

It's deeply disturbing to see him talking like this, but what makes it worse is the lack of action from the US Congress to act & hold him to account.

Is the US military leadership is the only thing left preventing an appalling outcome?

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.

Totally agree, our MG5 EV is great to drive and far cheaper to run than the fossil car it replaced.

BEV's are doing OK sales wise, but we really need more rapid growth in pure electrics rather than PHEVs.

Perhaps the Oil crisis and higher Petrol and Diesel prices will spur higher sales in future.

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.

Great addition to a recent blogpost from @nworbmot.bsky.social

Most of humans can go 90% solar in 2030. It's mostly northern Europe that's the edge case that also needs loads of wind. And the last 10% fuel... we'll take care of that before too long.

Excellent thread on atmospheric CO2 accelerating faster than fossil fuel emissions. Well worth reading the whole thread.

Along with observed higher climate sensitivity to warming this really really highlights how critical we stop burning fossil fuels as soon as possible.

We all have to act ASAP.

Wind and Solar generation reducing our need for Gas imports by £1bn is astonishing achievement.

This is £1bn that stays in the UK economy rather than leaving our shores to foreign multi-nationals.

It also lowers electricity costs for businesses and households.

These are benefits right now.

Ahh... the primary energy falacy.

It's just a terrible metric to use primary energy.

Fossil fuels are so incredibly inefficient to turn into useful work you have to burn so much more of it and waste the vast majority of the Fossil fuels primary energy to heat.

Far better to look at work done.
