I was replying to Fionboard mentioning the need for power stations as she mentioned things other than ships. Obviously things will be different for cruise ships but the principle of electric cars etc which were mentioned by Fionboard will be solved by the increased use of wind etc. Actually some of the big cargo ships are trialling clean energy and electric so no doubt it's going to be feasible at some point although not immediately. 2 Link to comment Share on other sites More sharing options...
Fionboard Posted July 25 #27 Share Posted July 25 6 hours ago, Megabear2 said: Power stations will not be required using wind or tidal for electricity production. The power goes directly into the grid system via substations. These are bigger versions of the ones you see on land around housing areas. Already large amounts of the UK's electricity is produced this way. The clean energy you see mentioned on your electricity bill is produced this way. The announcement yesterday regarding both onshore and offshore wind turbines will make the move to this clean energy even more of a move away to self sufficiency by the UK for their electricity. As acknowledged by the last government and currently being looked at by the new one, the problem that has caused the slow movement towards the energy all coming from these sources has been lack of growth of the National Grid infrastructure to actually join up the system to move the power to where it's needed. Both governments were/are committed to speeding up the planning process to upgrade the grid. This explains the process: https://www.nationalgrideso.com/electricity-explained/how-electricity-generated/how-electricity-generated-using-wind Really cannot see wind and solar providing sufficient energy required for electrification of everything.

We are already over half way there - 48% of our electric was produced by wind and renewables in 2022. The exiting government and the new one have cleared the way for land based wind turbines and licences for new offshore ones are now up for sale. We have a legal commitment to be neutral by 2050 and are on target for beating that, hopefully 2035. https://www.nationalgrid.com/stories/energy-explained/how-much-uks-energy-renewable 1 Link to comment Share on other sites More sharing options...

Imagine a February day with no winds blowing and cloudy sky. Apparently in norway the domestic electricty costs about 6p per kilowatt-hour with a 90% government subsidy if the price goes higher. Example - 100KwH would cost £6 but if the price increased to 12p per KwH the 100KwH would rise to £6.60 Edited July 25 by davecttr Link to comment Share on other sites More sharing options...

They could hang up great big cotton sheets. The wind would catch in the sheets and pull the ships along . I doubt that would catch on. 2 Link to comment Share on other sites More sharing options...
