6.1 Plug-in vehicle
Here’s a term you’re going to hear much more often: plug-in vehicle, and the acronym PEV. It’s what you and many other people will drive to work in, ten years and more from now.
At that time, before you drive off in the morning you will first unplug your car - your plug-in vehicle. Its big on board batteries will have been fully charged overnight, with enough power for you to drive 50-100 kilometers through city traffic.
When you arrive at work you'll plug in your car once again, this time into a socket that allows power to flow form your car's batteries to the electricity grid. One of the things you did when you bought your car was to sign a contract with your favorite electricity supplier, allowing them to draw a limited amount of power from your car's batteries should they need to, perhaps becau of a blackout, or very high wholesale spot power prices. The price you get for the power the distributor buys from your car would not only be most attractive to you, it would be a good deal for them too, their alternative being very expensive power form peaking stations.
If, driving home or for some other reason your batteries looked like running flat, a relatively small, but quiet and efficient engine running on petrol, diel or compresd natural gas, even biofuel, would automatically cut in, driving a generator that supplied the batteries so you could complete your journey.
Concerns over 'peak oil', increasing greenhou gas emissions, and the likelihood that by the middle of this century there could be five times as many motor vehicles registered world-wide as there are now, mean that the world's almost total dependence on petroleum-bad fuels for transport is伤残赔偿怀孕可以补牙吗, in every n of the word, unsustainable.
答案：While people drive to work, they will first unplug their plug-in vehicle before they drive off, and when they arrive they'll plug in their car into a socket that allows power to flow form their car's batteries to the electricity grid, so if their batteries looked like running flat and efficient engine running on petrol would automatically cut in, but the world's almost total dependence on petroleum-bad fuels for transport is unsustainable.
