Tim H,
Thank you for taking the time to impart your info. It would seem from your knowledge that things should be a lot better in the future, however, that doesn't help us much for the next few years.
I am being naïve in suggesting that we should all do simple things to cut down on power consumption such as:
Don't leave the tele on standby.
Switch off lights that are not required.
Turn the heating down by a degree or two.
I am sure there are many other things that we could do but is there really an appetite for this?
With regard to the diesel problem, well I think we have all been talked into buying diesel cars based on the mpg however, if you don't do a lot of miles I think the overall running costs are increased when taking into account servicing, fuel costs, replacing dirty particulate filters etc.
IMHO, a good lean burn petrol engine is still best for normal motoring leaving the diesels for the HGV trade.
