Re: If...
It's easy to just make these statements. The sad fact that is if you say it in an authoritative manner, some people will take what you say as established fact.
That goes for pro/anti arguments against green energy I should add, just as for pro/anti arguments about any emotive argument ("the bible actually says ..." being another prime example where people just say things demonstrably not true.
The people arguing a Range Rover is less harmful to the environment never seem to be people who actually care about the environment, and it's surely a bit of an anomaly how many of them own Range Rovers and could perhaps be motivated by self interest.
