I think it can be greener in several ways. First it allows you to move the energy generation to less dense areas where pollution is not as much of a problem (away from high density metro areas and traffic area's). Second it allows you to generate more efficiently (I assure you a couple of large plants maintained by professionals is cleaner than millions of small powerplants ignored by their owners.) Third it lets you be interchangable on your fuel. If you have solar or wind, use that but you can still use the current crop of oil/gas base fuels also and change when appropriate without requiring millions of people to convert.

>Maybe someone can tell me how these hybrids are greener. I mean, the lecky comes from your mains and somewhere fuel is being burned to supply this. If that lecky comes from a coal-fired generator then it's the people who live nearby who get the polution (same thing for "smokeless" fuel - coal - someone gets the smoke while the coal is being converted). We're told that we must be greener, and switch stand-by components off (something I do religiously btw) yet we have more and more devices on than ever before: phone chargers, flat-screen VDUs transformers, Nintendos, digital cameras recharging, digital radios (which consume more lecky than the trad. type btw), et al. Now the Volvo gets plugged in overnight!
