    Your post would mean more if a significant amount of our energy production wasnt already renewables and its only going to increase.

    I believe there has been one major instance of a datacentre running on gas 24/7 and some articles where new datacentres will have to do the same.

    An article in the New York Times about a group of people who worked together to vet installers, demystify contracts and, ultimately, install solar panels. Some people learned about the group from their local library. "Here’s how it works: Co-ops run for four to eight months and generally include 30 to 100 members. Around the third month, Solar United Neighbors solicits proposals from local installers, who compete for the business of the whole group. After the nonprofit does an initial round of due diligence on the bids, each cooperative appoints its own selection committee, which combs through the fine print and selects the best fit.'

    I can't speak for that occasion as I don't know the details, but what I can tell you as someone who actually works for a large multinational who owns datacenters and have seen them physically insitu, typically the diesel/gas turbines are installed for regulatory reasons so they can fire them up when there is a grid outage. They are not used for normal day-to-day operation. They don't like running them, not for financial reasons, but it causes more work.

    I'm now waiting for the inevitable "Ohh but you work for them ergo your biased!" No, I don't like them at all, but they are a necessary engineering solution to a engineering backup problem. Batteries can perhaps power a DC for 1-2 hrs. If the grid stays up, they'll never be fired up other than on the proper maintenance cycle to confirm operation. The alternative is that if the grid goes down then all manner of fall out happens from your bank machine not giving you money, train timetables not longer on your phone app….. to your nexflix movie going off. DC's are a modern fact of life. They need to be online 24x7 and anyone who thinks the country could run without them….is probably naïve.

    That said, I'd still get them to pay a premium for (more) than their share of infrastructure upgrades that are necessary due to their existence. that's fair to me. Everyone wins.

    The upper limit to how much energy to fuel will cost in the future. Or a real breakthrough in carbon storage that isn't greenwashing.

    Germans were making synthetic fuel during WWII so it's not new tech. Costs are mainly down to the price of hydrogen, which will be down to the cost of surplus renewables.

    Ammonia is another option for ships and possibly trains.

    https://www.boards.ie/discussion/comment/123754962#Comment_123754962Thanks for the detailed description. I'll leave the talk of generators out, my comments seem to be blending with an existing conversation about backup gennies.

    I've managed sites similar to datacentres with backup generators so I'm quite familiar with them. I just wasn't talking about backup generators but that didn't come across.

    Those giant generators you're referring to are called Flexgen generators

    It's basically a jet engine strapped to a generator and powered by natural gas

    The idea is pretty simple, it gives you a quick startup generator if there's a need for peak power. Because there's multiple turbines you can spin them up and down as needed, unlike many larger thermal plants which are a bit all or nothing

    They're there to cover shortfalls in renewable energy, they aren't designed to be run constantly and won't be

    The reason we can't have more renewables in the grid at the moment is because the grid was designed around large generating plants and needs a lot of rework to handle renewables

    The 80% figure is total energy consumption of the country, that includes transportation, heating and industry. Electricity generation is something like 30% of the total so even if that was fully renewable it doesn't count for the majority

    The ex peat fired station up the road from me is still running with an aircraft engine instead. My oil delivery man was describing it to me, he makes regular deliveries of fuel to it. It's gas, pardon the pun, you'd end up in court around here for selling a bag of turf.

    Happy for being islanded and generating all day during a power cut, proper cofffee, full office set up, toasted sandwich for lunch.
    Sad for the lost export potential and the fking neighbours' house alarms ringing THE ENTIRE TIME

    Funny story: Back in the early 2000's there was an alarm across the street and a few doors down ringing constantly for more than a day or so. They are now all forced to stop ringing after 15 mins by EU regs, so this must have been an an old alarm.

    Anyway owners must have been away on holliers or something and I saw the next door neighbor of the house come out his front door, bring out a ladder from the side passage…….claw hammer in place, climbed up the ladder and proceed to lash the absolute bejasus out of the box until it was scrap on the driveway.

    Problem solved. LOL

    Having been there I can appreciate it, coming in off the likes of shift work or even having to sleep in general with a loud house alarm within a few doors is near impossible

    I was working the front desk in a clubhouse years ago, there was a building nearby that had the alarm going off the whole bank holiday weekend

    It was obviously an older one that didn't stop. I was on all 3 days for 8-12 hour shifts the whole weekend, I could hear the thing in my sleep by the end of Monday

    We had constant complaints from members about the noise so we eventually spoke to the guards. They were immensely unhelpful, they didn't have the building owner on their records and would have to contact the land registry to get the details

    The land registry of course wouldn't be open until Tuesday 😫

    House alarms, the most stupid and useless appliance ever. Why do we insist on using them? Pretty much nobody in continental Europe has them

    I don't know. But no alarm has ever stopped a scrote from breaking in 😂

    On a more serious note, they do a lot more harm than good. See the above annoyances, and those are the milder symptoms. Just picture the thousands and thousands of people who have lost serious sleep over alarms going off 😒

    I heard a security "expert" on the radio before saying a scrote would prefer a house without an alarm box as a priority to burgle. Possibly a shill for alarm systems 😆

    At a guess hijacking keyfob signals for nicking cars has probably avoided house breaking instances.

    There are very few cars without rolling code key fobs anymore, recorded code can't be used again. Maybe some jap imports.

    Relay attacks are becoming far more common now, where they hijack the rolling code from the key in the house (especially if the keys are near the door).

    That's why Faraday pouches/boxes are becoming more common to store keys in.

    Yeh. Keep mine in a little Faraday pouch. Car is nothing special. Just don't want it nicked as we only have one car.

    Best place for them. If someone breaks in, they can grab the keys and make a getaway. Insurance will cover it. If the keys aren't there, they might go look for them. Maybe even kindly or not so kindly ask you or your family where they are.

    If you listen to the Verisure ads, the language is real evasive when they give the impression that someone will race around to your house if the alarm goes off. They will. In their hole.

    Speaking of pulling the pin…

    https://connachttribune.ie/wind-farm-company-loses-e35m-state-bond/

    There's one offshore wind farm that won't be going ahead. I expect more to follow.

    That's pretty old news (announced last April), and it looks like pulling out was a decision which has cost the company €35 million now

    Any particular reason why you're expecting the imminent death of other wind farms?

    Personally I don't see how this practice of shelling out to private companies who will up sticks and leave when it suits them is supposed to succeed. It isn't limited to wind either as several contracts for gas power stations got abruptly cancelledby the vendors a couple of years ago
