    A balanced energy solution would always contain nuclear power, particularly now that much smaller units are an option. By that means it would be perfectly feasible to phase out fossil fuels.

      I just live up the road from Sellafield. They were going to build a new nuclear power plant that would of been the biggest in Europe until Toshiba pulled out. It was then earmarked as a suitable site for nuclear fusion reactors, now it looks like it's going to be used as a storage facility for plutonium, which is not getting as much support from the locals. The trouble has been the political parties, yes/no attitude for to long.

        They have shut down both reactors now at Dungeness, as far as I know and no plans to build another one.
        It makes no sence to me as all the infrastructure is there just rotting away.

          Indeed - we should also have shops, supermarkets, factories and car parks all covered with solar panels on their roof. Why can't we have solar panels alongside railways and motorways too?

            That is also an issue - and there is a similar problem comes out of the lead up to that too, very similar to that of the generator.... You cannot simply whack a generation source (or a large one) onto the grid, flick a switch and all is well - it has to have it's output frequency stabilised as near as dammit 50Hz - even very small drifts away from that can destablise the grid and cause power cuts. Traditional generation methods (nuclear, gas, coal etc) are all speed controlled to accommodate this and whilst turbines have brakes on them to moderate them, if they drop slightly under speed, there is bugger all can bring that speed back up.

              They raised that issue on the programme. The further North you go and even if you have solar panels fitted, the heat pumps would actually still need a back source of power. If ever there was a power cut in the cold winter months the energy generated from the solar panels would still be insufficient.

                When my air conditioner unit needed repair summer before last, the fellow tried to sell me a heat pump. He said it's more efficient. blah blah blah Then said that because our winters are so cold, we would still need a traditional furnace to keep the house warm during the winter months. So I had the air conditioner repaired - the heat pump, to me , would have just been an expensive air conditioner that could add a little warm air to the already gas powered heat the house would have. Totally silly. To me anyway.

                  I had an assessment for an air source heat pump system it was told it would be too expensive to bother. Apart from a partial grant towards the capital cost of the system we would need to have all our radiators replaced by larger ones and it would still be unlikely to heat our place to the temperature our old and frail bodies now require.

                  He said that it would work OK if we had underfloor heating instead but our floors are concrete!

                    I was reading that earlier. EU inflexibility has always been an issue, but the difficulties are really reaching crisis point.
