  1. Does it mention lowering atmospheric CO2 by 150+ppm.
  2. I don't think so. Wind turbine blades are made from the same plastic as swimming pool slides. We could just pile them up as the degradation is fairly benign. There are also ways to recycle composite plastics, just not done that much as we don't have a huge market for it.
  3. I think London 'imports' most of its energy, so probably takes the percentages from the surrounding areas. There is a bit of a problem with zoning the country and then proportioning pollutants to that area. A lot of Cornwall's energy comes from the gas plant in Plymouth, and some of the waste at the St. Awful EFW comes from Devon (they just won't stop sending there shit to us). It is a bit of a nonsense to try and proportion, exactly, who is generating what. May just as well do a Carbon Intensity by population density, then we can claim that all Rural people are wasteful. The main thing is to reduce the national levels. I am just about to drive to Aylesbury, so shall be passing though, Devon, Somerset, Avon, Gloucestershire, Wiltshire, Oxfordshire and Buckinghamshire, with a tank of diesel bought in Cornwall, that came from a fuel depot in Devon, from ship that has come from Rotterdam, with oil that was probably refined in India, from Alaskan or Middle Eastern, or may by even Venezuelan, crude. When I get back later today (hopefully), I will have to fill up again, in Cornwall. How do I proportion that environmental costs to that simple journey. You have about 6 hours to answer that.
  4. I think there is some hydro on weirs in the Thames. There is one near Windsor Castle, but that isn't London.
  5. Much of the cost is for future decommissions, which was never priced in with the earlier nuclear power stations. Back in the late 1980s and early 90s, we were the worlds largest manufacturer of wind turbines. That changed. We have also bought into an untested design from EDF, the EPR. Same design as Olkiluoto 3, which is still not producing, 17 years after construction started. https://en.wikipedia.org/wiki/EPR_(nuclear_reactor)
  6. 50°C for UFH is very hot, too hot to walk on.
  7. Over how many day? About right for two people, will go up a bit, maybe a kWh/day in the winter. As @ProDave says, our radio switches are on GMT, but the billing window does change sometimes, but your energy provider will let you know. They sometimes, for load balancing reasons, shift the time. Sometimes I have had power in the afternoons for half an hour or so. This is billed at the night rate.
  8. That is public ignorance, not really anything to do with changing over from FF to RE. It is 3 times the price of RE alternatives though.
  9. Or your head/budget will compromise on.
  10. I don't comment on people house designs (well I did once). But I get the same endorphin release from sitting down with a coffee, a good book and a Marlboro. I also get the same health benefits as cold water swimming, from a hot bath. Just saying
  11. Not yet, but it is early days on the RE journey. Here is a breakdown of the 2752 major installed capacities. There is a total capacity of 97,155 MW on the grid. That is almost 100 GW of capacity. Source Capacity /MW Capacity Percentage /% Gas 29916 31 Wind 23202 24 Coal 12296 13 Nuclear 8918 9 Solar 8675 9 Hydro 6365 7 Cogeneration 3006 3 Waste 1886 2 Biomass 1584 2 Storage 897 1 Oil 372 0 Wave and Tidal 38 0 Not that far to go really, especially when you see that there is less than a GW of storage.
  12. Highest in South Wales usually. Get purple/yellow sunset when there is a NE wind blowing the Welsh air down here.
  13. Just be listening to yesterdays Any Questions. Lionel Shriver says that the housing problem is to do with immigration. About 40 and a half minutes in. Should keep the people of Sarratt in Hertfordshire feeling safe. DWIBNH
  14. Well yes, and no. It is local councils who decide the future needs, and we vote (or usually don't vote) them in, so that is the choice of the people. Price is a difficult one, regardless of supply levels, developer profitability, or need, if something is being sold out and someone cant buy it, then it is too cheap. The problem is really distribution of sales, not the actual product/service on sale. Or ignorant purchasers. If people were really struggling to find anywhere to live, they would go to the selling agents and point this out every Saturday morning. The selling agents, who seem to have no problem selling homes, will not see a problem otherwise.
  15. A few people on here claim, and back it up with 'evidence' that low CO2 electrical generation cannot work. I just had a quick look on the Templar Gridwatch site (this is the proper gridwatch site). Gas is supplying about 9% of out power. Now I know it is a Saturday, but at 31 GW of power being delivered, it is not particularly low, but it is a fantastically low amount. So the next time someone says tat RE does not deliver, remember this. And, if they want to get cute and point out that the capacity factor of RE is dreadful, tell them to look at this site: https://electricityproduction.uk/plant/ It shows the utilisation of different generation installations. Pembroke is currently at 8.7% utilisation. Nearby Wear Point wind far is at 42.9%. For some reason the solar reporting is not working today, probably got one of @Radian's RPis attached to it.
  16. It could be argued than main stream developers don't design what the public want at all. But, if all new houses get sold, then they are what people want, and too cheap.
  17. A decision I made when I was about 12, been one of my good ones.
  18. I have 6 in my tiny 2 bed terrace.
  19. I have cured the legacy support after death. Stay single. You all know it makes sense. Shall I get my coat again.

    You need to fit a mass flow sensor on the pipework. This is generally the bit that is missing. Temperature sensing is cheap and easy, £200 of DS18B20s strategically placed all over the place will give you loads of useful data. You can add extra 1wire GPIOs to a Raspberry Pi Zero W to save overloading one pin and build in redundancy that way, modify the /boot/config.txt file. dtoverlay=w1-gpio,gpiopin=x Where x is the extra GPIO pins. You can do similar with i2c.
  21. Borrow @pocster's tape measure, you may find that the hole and the glazing are different.
  22. Could shorten the life of your fuses.
  23. Only if not too old, and female. I shall get my coat

    Disregarding my flippant remarks about additive CoP. Space heating and DHW are different things. They operate at different temperatures and at different times if the day. You will almost certainly be adding forced ventilation if some sort. I have never looked at the numbers as they are hard to come by, but I often think that even with MVHR at a more realistic recover rate if 80% over the year, the other 20% may be enough to heat most of the DHW. What we need is output energy sensors on all heating heating systems, then the data would be easy to analyse.
  25. It is the Chinese, or Russians. Or MI5/6, NSA. Or could be that they cost a tenner.
