This insistence that Im somehow lying by providing actual, realtime power generation numbers is getting a bit tired now.
Ive made a couple of posts around 0930 where its been more than 50% clean energy, its now 1000 GMT and 14.4% is fossil fuels. If you look a bit further down fossil fuels only generated 11.6% in the last 24 hours. In the middle of winter. In the UK. Actually, Ill save you the time:
For your other example Im not even going to get into the maths, but 85mph average speed for 13 hours carrying 250lb isnt your average drive, is it? Factoring in cost of hotel room and meals because 13 hours becomes 15 isnt going to be the calculation most owners will do before purchase, by your workings anything <11 hours would take longer but cost less.
