December 25 is just about the only day when electricity demand in Ireland peaks around lunchtime rather than in the evening 🎄

When else can you expect this behaviour? Easter Sunday. We love our roasts! 🍗

Renewables supplied over half of this year's Christmas Day electricity 🔌

Renewable generation and discharging storage equalled 76% of yesterday's electricity demand, with a peak of 86% at 21:45. Fossil fuel generation (mostly gas) equalled 27% of demand. 5% of generation was exported, 2% of demand was met by imports.

A screenshot of Green Collective's records dashboard. It shows current and past wind output records in MW (red dots) and as a percentage of demand (blue dots) on the Irish grid. It also lists out top 5 timestamps with highest all-island wind output, the top one being Friday December 5 2025 @9:30: 4671MW.

🚨Our dashboard caught a new all-island wind output record this morning: 4671MW at 9:30am on Friday, 5 December!🚨

You think you can’t love the Green Collective lads more and then you find they’re Princess Bride fans.

Curious who might be the Dread Pirate Roberts of the Irish electricity system…..

Huge amounts. Someone told me yesterday we had a GW or more of wind turned down/off while simultaneously importing.

Fantastic news! Record smashed with three and a half months to go!

China's EV charging network hits 16.7 million units, records 7.71 billion kWh monthly usage Global leader China boasts 16.7 million EV chargers, consuming 7.71 billion kWh monthly.

China’s EV charging network surged 53% YoY to 16.7M units. Europe? +35% to just over 1M. US? +20% to under 200k. Tesla? ~65k plugs. Nobody’s even close—this is how seriously China is taking electrification & its energy transition. Keep up or get left behind! 🚗🔌🔋⚡🇨🇳 #EV #EnergyTransition #BEV #RIPICE

They will try to tell you, “Resistance is futile.” It is never so.

4.6 Billion Years On, the Sun Is Having a Moment In the past two years, without much notice, solar power has begun to truly transform the world’s energy system.

“California is so far using forty per cent less natural gas to generate electricity than it did in 2023, which is the single most hopeful statistic I’ve seen in four decades of writing about the climate crisis.”

The bar for June 2025 is a paler colour to indicate that data is incomplete because the month is not yet over. All-island figures. Renewables comprise wind, hydro, solar, and biomass.

Renewable generation in Ireland has exceeded 1TWh for the first time ever in a June month. That's equal to more than 35% of the island's electricity demand.

Statistical Review of World Energy for 2024 is now available. Hidden inside the large spreadsheet is this gem.

Note that calling a peak is fraught with problems. Often you don't know peak happened until a few years after. But there are SO many signs pointing to this moment coming!

Losing. To Tipp. Badly.

Ireland’s privatised waste collection system is broken- only the state can fix it Domestic waste collection is not a typical market and having lots of bin lorries driving down that same street does not serve the consumer interest

Great column in the Business Post making many of the same arguments against full privatisation of waste collection made by anti-bin tax activists 20 years ago.

Strange to see it coming from the Competition and Consumer Protection Commission!

Sunk costs in fossil fuel infrastructure could sink us The greatest cost of new fossil fuel projects may be the missed opportunity to build clean energy

Great article by @hannahdaly.ie in the paper this week. A healthy dose of common sense in a context where so much discussion of energy issues and the merits of fossil fuel infrastructure is fantasy stuff.

Congestion pricing is an unqualified triumph. One of the most immediately, strikingly successful public policies of my lifetime.

Pints and politics this weekend. Strongly recommend this book by British journalist Ash Sarkar. Read it in a day, terrific political analysis.

52 Times Britain was a Bellend: The History You Didn't Get Taught At School Buy 52 Times Britain was a Bellend: The History You Didn't Get Taught At School by Felton, James (ISBN: 9780751578850) from Amazon's Book Store. Everyday low prices and free delivery on eligible orders.

Maybe a little young at eight but, on the other hand, are we ever too young to learn about our neighbours?!!

Haven’t cycled in town in ages but really hadn’t geared myself up again for the lack of space for cycling. The city REALLY needs to improve for road users other than cars, buses & trucks. Most of my headspace was taken up hoping I’d make it home to my kids in one piece! Do better DCC… 🛻🚙🚚🚛🚌🚴‍♂️🚑

The Infancy Gospel of Thomas as I learned from this book.

Arguably the greatest political self-saboteurs in the, very broadly defined, global left.

And that’s a tough field.

Jesus had killed two people by the age of five, and sold slaves, and his Mam cut off the hands of another woman in a really interesting way.

Fascinating story of the Christian gospels and teachings that got edited out and, in some ways, live on in Christian teaching. Great read.

Wouldn’t you be mortified if, as a political activist, this was the best you could come up with?

No wonder these boys lose elections they should win.
