I just heard an interesting interview on global public media here:
http://www.globalpublicmedia.com/interviews/610
Dr. Joseph Romm says the peak-oil doomsayers like Kunstler miss that electricity is a very obvious substitute to oil - assuming we mount an all out investment program in renewable energy. Romm then discusses a new form of car that I had not previously been aware of. He says
plug-in electric hybrids are the next step beyond the current hybrids. We've had electric vehicles for a long time, but they take a while to charge and their range is much more limited than gas. As with any electric vehicle, the plug-in electric hybrid allows you to charge your vehicle at night then commute to a job say up to 20 miles away, completely on electric power. But, if you want to go on a long drive
the car also has an I.C.E. so that you can use gasoline and not have to stop and recharge every 40 miles or so.
My understanding is that hybrids such as the Prius only get their energy by regenerative braking - capturing wasted energy originally released by the burning of gas. The plug-in electric hybrid has the potential to be 100% sustainable for everyday use (assuming that your choosing renewable power from hydro, wind or solar), while still allowing you to utilize gas for long distance travel when needed. Romm indicated that these cars are beginning to appear, as the technology to make them possible is already well understood.
This just might be the technological wrinkle that convinces me to at least get my drivers license. I'll be researching this more and add any additional worthwhile info I find.
