Hey Fedi!

What's this thing on the high-voltage line?
There are sections where there is plus one wire for maybe 20m, separated with glass beads from the main one, and it ends with a tube that looks kinda like a fuse.
(Edit: under the big red ball.)

My guess is some kind of sensor or safety device. I see no connections to / from it.

"""
From 2005 to 2017, the amount of electricity going to data centers remained quite flat thanks to increases in efficiency, despite the construction of armies of new data centers to serve the rise of cloud-based online services, from Facebook to Netflix. In 2017, AI began to change everything. Data centers started getting built with energy-intensive hardware designed for AI, which led them to double their electricity consumption by 2023.

Britain: you absolutely cannot have a regular power socket or wall mounted switch in a bathroom, go put that washing machine in the kitchen.
Also Britain: the best way to heat up the water in your shower is through an electric device mounted inside the shower, even if you already have a gas boiler.

"...and our electricity here comes from a renewable source ... nuclear ..."

Let me just stop you there. You don't need an Oxford degree to know Nuclear might be low carbon (construction depending) but it aint and can't physically *be* renewable.

Unless those clever boffins have figured out how to break entropy and rejoin U235 atoms.

How #DeepSea Cables That Power World Are Made
#Undersea routes are often preferred option for sharing #electricity between countries or simply keeping cables out of sight
“We are basically sold out through 2028,” Massimo Battaini, CEO of #Prysmian, said in an interview at the plant. He added that orders on the books for these conduits, which can carry up to two gigawatts of power, have jumped to around €17 billion from €2 billion five years ago

#Solar was the leading source of #electricity in the #EU last month, says report
Picture remains very different in #Canada, where solar is still a small share of electricity generation
Solar generated 22.1% of the EU's electricity last month, up from 18.9% a year earlier, as record sunshine and continued solar installations pushed output to 45.4TW hours. At least 13 EU countries, including Germany, Spain and Netherlands, recorded highest-ever monthly solar generation.

CBCSolar was the leading source of electricity in the EU last month, says report | CBC NewsCoal generation fell to a record low during June 2025, and experts say that the EU's power system is changing. The picture is very different in Canada, where solar is still a small share of total electricity generation.

What's been quite fun over the last few weeks is finding an electricity supplier with a free three hours of electricity during the day (11am-2pm). We work from home, and we find that the 11am deadline is enough to get us up from our desks and loading the dishwasher/washing machine etc, and seeing how much electricity we can feasibly use during that time. (The solar panels are normally at full generation then, and so are supplying half the power we use at that time anyway. Cunning.).

What's also been fun is a) fixing the solar inverter to report locally every five minutes, rather than fifteen; and b) getting the Home Assistant box to use this better data to calculate how much our electricity is costing at this moment.

The "bumps" in consumption at 9am-ish today was heating; then our solar took over. By 11am, you can see us turning everything on - the pool pump kicks in, the hot water heater, the dishwasher, the washing machine... fun!
