Answer because they would lose loads of money!! Well, wouldn't you if the subsidies stopped? Quote Link to comment Share on other sites More sharing options...

A 20MW turbine doesn't exist yet, although admittedly they seem to being explored at the moment and appear to the maximum possible theoretical size using current technology albeit still commercially unviable. Earystane = 5 x 5MW turbines which will be 150m - 200m tall. Druidale = 10 x 2MW turbines at 100m. A 20MW turbine would likely have to be around 350m tall (the height of the Eiffel Tower) and have blades that cover the area of approximately 10 football fields. The Chinese have built a 16mw one, which is 242m tall. Site one of them off the point and totally dominate the north irish sea Edited October 5, 2023 by TheTeapot Quote Link to comment Share on other sites More sharing options...

doc.fixit Posted October 5, 2023 Share Posted October 5, 2023 If you only have one mill and it breaks then you are stuffed. If you have a number then one goes down you still have some power. Quote Link to comment Share on other sites More sharing options...
Fred the shred Posted October 5, 2023 Share Posted October 5, 2023 Encouraging more people to invest in Solar would be great people I know who have had roof panels installed reckon it has been really effective inreducing their electricity bills. 2 Quote Link to comment Share on other sites More sharing options...
GD4ELI Posted October 5, 2023 Share Posted October 5, 2023 This year I had panels installed in February. Usage the same, just far less from the grid. 1 Quote Link to comment Share on other sites More sharing options...
Max Power Posted October 5, 2023 Share Posted October 5, 2023 Apparently the cable manufacturers of undersea cables, of which there are four worldwide, are totally sold out until 2030. This will determine how many projects go ahead on time. I'm not sure on land based cabling, but I imagine it may be the same, unless we are also planning for pylons?

Cambon Posted October 6, 2023 Share Posted October 6, 2023 Hence the reason Fred the Shred’s idea of helping people invest in PV panels is probably the most sensible way forward. No massive projects. No massive upgrade to the existing network. No huge expense in purchasing white elephants. All of which means it will not happen. 1 Quote Link to comment Share on other sites More sharing options...

It will take years to get your money back. Most people on here will be dead before they get their money back. They don't last forever either 2 1 Quote Link to comment Share on other sites More sharing options...

It wont happen because its cheaper to use bigger roofs that already exist than 'help' those than can afford, paid for by those who cannot 2 Quote Link to comment Share on other sites More sharing options...

Interesting that there's a consideration for a 1500km geo-thermal pipeline carrying energy from Iceland to Scotland. Great idea. Quote Link to comment Share on other sites More sharing options...
