I keep getting this message when trying to post.

The following error or errors occurred while posting this message:
Error - you have used a blacklisted term

Suddenly, apostrophes are not allowed?

Seems too silly to be a new policy so must be some kind of bug in the system I guess.

APOSTROPHES ARE ALLOWED AGAIN

For those that don't know the "Renewable Energy Foundation" claims that it "is a registered charity promoting sustainable development for the benefit of the public "

Whereas actually it's a campaigning organization set up by Noel Edmonds solely because he didn't like the look of a wind turbine somewhere around his (no doubt very expensive) house.  It's set up specifically and only to ensure that wind power doesn't get used in the UK.

Incidentally, electric transportation is about 4 times more efficient than fossil fuelled transportation. It's perfectly possible to power an electric car your normal mileage using the electricity from a domestic roof PV. You need just 5kWh generation per day to get the average car mileage.

The UK has a pretty good charging infrastructure now and it's likely to further improve.
Reading Motorway Services has parking space for about 600 cars and 100 trucks, with two recharging points. OK for "early adopters" (I've never seen either charging point occupied!) but a long way short of providing an adequate replacement for liquid fuels.
Right, so you've never seen anyone using a charging point, but you know it's not adequate??? How stupid do you think we are? Or how stupid are we supposed to think you are?

And as I am sure SS will agree, if you replace all road transport with electric vehicles, you will need to double your entire grid capacity: generation, distribution and storage.
No, electric cars are 99% charged using off-peak electricity,  because it's much cheaper. And it's cheaper because the grid is underused.

Cars, on average, go 20 odd miles a day. They use ~0.15-0.25kWh per mile. So that's ~4kWh of electricity per day. How crummy would the grid have to be to be unable to handle 4kWh for a few million electric cars????

To put this in perspective, the UK grid produced 317.5 TWh in 2012. If there were 60 million electric cars on the road (there aren't that many cars, never mind electric cars), that's about 240GWh, about 0.1% of the total.

Basically, you're absolutely, completely and totally full of sh1t.
