  1. Well that is the thing. Fossil fuels, or I would rather describe it as fossil resources are limited. I remember years ago hearing a talk about climate change, about increasing CO2 in the atmosphere and how mankind is affecting the weather. But what I remember from that talk was a comment in the closing remarks. I’m not sure that I can quote it exactly, but it was along the lines “Even if you don’t believe in climate change, oil and gas is too valuable to just burn”. That comment stuck with me. Sitting at your computer, what is it made of? Your clothes, your furniture, significant parts of your car will all have plastics or other materials made from hydrocarbons. If oil and gas extraction goes on at present rates, how long will it last, 20 years? 200 years? I don’t know, but I’m absolutely sure it won’t last 2000 years. So I wouldn’t say that all oil and gas extraction should be totally stopped, what I think is important is that it should be preserved for making other things and not simply be burned for uses like generating electricity or powering motor cars where other options are available. Yes preserving hydrocarbons has a “green” bonus to in terms of not producing so much CO2, but I think that reducing the use of a limited natural resource that is really useful is reason enough to try to preserve as much of it as possible for the future.
  2. Suggest you try J A & G D Nicolsons, phone number listed on their website is 01950 477573. In addition to buses, they have lorries, and are involved in agriculture. I am sure that it would be worth giving them a ring.
  3. Of course, this isn’t the first interconnector to take energy from Shetland to keep the lights on in the rest of the UK. Googling gives different answers, but what seemed a reasonable report gave the cost of the Laggan Tormore project as £3,500 million, so nothing comes cheap. https://www.energyvoice.com/oilandgas/101001/laggan-tormore-fast-facts-and-brief-history/ Since much of UK electricity comes from gas, all electricity users are now paying for that interconnector whenever a gas turbine is running. But at least oil/ gas producers don’t get “subsidies” like there is for renewable energy producers. No, they get “tax breaks” met by all the rest of us taxpayers. So presumably that is ok then – at least if you use a lot of electricity and don’t pay tax. Probably won’t live long enough to know for sure, but I bet that the wind will still be blowing and able to send electricity down the wires long after gas has run out at Laggan Tormore.
  4. It looks like the roof covering was pressed metal tiles. https://www.metrotile.co.uk/case-studies/fair-isle-bird-observatory/ I couldn’t find anything in the construction details as to how the wires from the photovoltaic panels are or should be taken in through the roof.
  5. Bulb is one of the newer energy companies, they have an “Economy 7 meter” tick box on the page that lets you look up their tariffs. I am told by someone with Bulb that they are very good at responding to any queries you have; they are happy with them and their prices. With Bulb,you have to give them all meter readings yourself online, perhaps I think also emailing them a photo of the meter when you change over. We are on year three of a three-year fixed tariff with SSE, now a very good price, but plan to look around when that expires.
  6. You missed an important bit, online is charged at cover price, so no saving by going digital. But it is available first thing on a Friday morning, and you don't have to fetch it from the shop.
  7. Not been to Sumburgh since they started charging – someone said that the overspill car park beyond the hangers isn’t included. Is that right?
  8. No Tavish. There are paid for car parking all over the country, and I am sure very very few are covered by CCTV. I don’t think that CCTV is seen very often as preventing/ solving all the crime and vandalism in Lerwick. The responsibility for vandalism is the vandal, like it is everywhere else. If HIAL were negligent – perhaps leave something unsecured that blows over in a moderate wind and damages a car – then there would be a good case for them to be held responsible. But not for some random person acting illegally.
  9. Your mother was there and heard what was said, I wasn’t; so its not for me to say anything more on that. Respect should certainly be shown by anyone visiting someone else’s home. Tone and attitude are as important as the actual words used, and only your mother can make a judgement on that (even if allowance is made in his choice of words, that English is not his first language).
  10. You say that the meter reader had poor English, so did he also have an accent, and so was a bit difficult to hear and follow? Might he have also have said “here” as he questioned about the dog – “Do you want to keep your dog here?” Answering by saying he is on a lead is the same as saying that the dog will be kept in the same area as the meter man is to work. So was the man threatening the dog? Don’t know, but I think it was more likely that the man was planning to leave if the dog was not going to be moved somewhere else. Training? When a meter change is being arranged, a householder is always asked about any dogs in the house. I guess that a meter man’s training is to walk away if a dog isn’t being kept at least a closed door away from where the work is being done. So I think that this is more likely to be a case of English as a second language, speaker with an accent and misunderstanding.
  11. One issue is that electricity flowing through a wire generates heat. With a bare wire way up in the air, that isn’t a problem. But cover it in insulation, bundle three wires together and add more insulation, bury in the ground, then heat does become an issue. The way around that is to use bigger wires to have less resistance and therefore produce less heat. But more copper costs more money, add insulation, armouring and laying; the result is that underground cables are expensive compared to overhead if moving a lot of power over a distance.
  12. A power cable isn’t the same beast at all as a phone cable. Photo shows how to lay one. Okay, equipment and machinery have become available and developed since that photo, but it wouldn’t be a small cable to supply any quarter of Shetland. If the link below doesn’t work, look for photo number W00027 on the museum website. http://photos.shetland-museum.org.uk/index.php?a=ViewItem&key=SXsiTiI6MywiUCI6eyJ2YWx1ZSI6IlNUMDAwODMiLCJvcGVyYXRvciI6IjEiLCJmdXp6eVByZWZpeExlbmd0aCI6IjMiLCJmdXp6eU1pblNpbWlsYXJpdHkiOjAuNjUsIm1heFN1Z2dlc3Rpb25zIjoiNSIsImFsd2F5c1N1Z2dlc3QiOm51bGx9fQ&pg=3&WINID=1541979584621#wLOpPzwe29AAAAFnBSUynA/36952
  13. Battery storage in conjunction with tidal (and other renewal) power – that has to be a good step forward. Anyone seen any spec for the battery – power/ capacity – and is it in place yet, or is it still just a proposal?
  14. I would always use treated timber, but my experience is limited.
  15. Well, the power station exists. Electricity comes out the ends of the wires when you switch on a light bulb. So I am willing to believe that SSE does exist. And willing to believe that wind turbines means that they don’t use quite as much diesel as they would do without them.
