Will AI and data centres be the main drivers of future electricity demand?
No. The biggest drivers will be the electrification of industry, transport and buildings. When powered by clean electricity, the benefits are fundamental: vastly higher efficiency, dramatically lower emissions & cleaner air.

Assuming a ring road is in place by 2040, the report suggests a short-term alleviation of traffic flow in the city centre after 2030. “However, increased transport demand will eventually result in the bypass becoming congested without further intervention,” the report warns.
Expect soaring congestion costs
A long-anticipated report into congestion across Irish cities has been circulated several months after its publication, and its findings for Galway city are damning.

The same for journalists. If a politician or business leader spits out 1.5C or net zero, ask them how fast emissions need to drop to reach net zero in 2050, and how fast they are dropping today. Point out the contradiction. Make them explain it.

Most of Ireland's uplands are commonage, ie co-owned by local farmers.
The ONLY real income from commonage is via subsidies, almost always for ecosystem-killing sheep. This is why Irish mountains are all empty wastelands, kept that way by your taxes.
Why are we STILL not paying farmers to rewild??

Renewable generation (that's biomass, hydro, wind, and solar) never dipped below 50% of electricity demand yesterday. Overnight, it exceeded 100% for a little while around 1am.
This is still rare outside of the winter: we saw it in Aug/Sep 2023, only in winter in 2024, and now in Aug/Sep 2025.

On Monday, large-scale solar generation in Ireland reached a new high of 934MW; about 19% of the island's electricity demand at the time ☀️
This took us by surprise - it's nearly October! It seems transmission constraints on the grid were notably lower than usual, perhaps due to extremely low winds.
