I guess hydrogen use is a variation on the theme, I don't know how they imagine it will work, but I'm sure, there are plans and plants already in place for this and 3 countries pledged to have zero green house emissions by 2021, which is said to be perfectly possible. :?
And there is the hybrid car with electrics. Reason I'm asking is, they say, to reduce your carbon footprint don't buy a new car as it is more emissions to manufacture one, would that be only true about traditional fuel models?
Because, they also say, lose your old fridge from the garage. And we had to replace a few electrical appliances in the last 2 years or so(bought A rated), in fact we use more of them than before but our electricity bill decreased.
So the promises about an energy and fuel efficient car sound tempting, but there is a big hmm, is that really so?
