Six months ago I wrote this post about “the next terrorist attack.” I republish it now (lightly updated) because my fear of this scenario has recently grown much greater.

Old phones, fridges or laptops don’t just disappear when tossed.

The world generates 62 million tonnes of e-waste each year, enough to fill 1.5 million trucks.

New regulations, circular design and better recycling can help stop the toxic tide and #BeatWastePollution: www.unep.org/news-and-sto...

72.3GWh yesterday from wind, solar, biomass, and hydro was equal to 68.3% of the island's 105.9GWh of electricity demand.

In other words: the best ever July day for renewable generation in Ireland 🏅

All day long, these four sources were supplying >50% of demand.

We just had the greenest June ever for Irish electricity, with carbon emissions falling below 600,000 tonnes in any single month for the very first time 🥇

Head of Signal, Meredith Whittaker, on so-called "agentic AI" and the difference between how it's described in the marketing and what access and control it would actually require to work as advertised.

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.

We've just had two record-breaking days in a row for Irish solar:
- on Wednesday, solar farms produced 8.1GWh, a new one-day record
- on Thursday, solar farm output reached 861MW, a new high

On these strong days, solar farms are fulfilling about 7% of electricity demand with peaks of about 20% ☀️🔎

Fine Bank Holiday weather!

Yesterday, wind generation exceeded 4GW (about 95% of electricity demand at the time) for the first time in a June month, smashing the previous all-time high of 3.5GW set last year.

Fossil fuels also dropped below 1GW last night; grid carbon intensity numbers to follow!
