Kicking the Oil Habit How to get alternative fuel cars on the road, Lots of them, Right now. by Peter Gray or years I had been substance-dependent, and it was time to get out. The stuff...
...Once the dust settles in the desert, maybe Americans will realize that there are better ways to get their hydrocarbons than by fighting for them, and that there are better ways to get to work in the moming than by driving a gas guzzler...
...All energy sources should then be taxed in proportion to the costs they impose on society through pollution, resource depletion, and security risks...

...Silent running While we’re waiting for these natural gas filling stations to sprout up, we can begin switching to electric vehicles (EVs...
...Clearly, in many of these households-more common sense-the family tends to rely on one car for trips around town, another for trips on the open road...
...Adding compressed natural gas capability runs about $2,000, in part because it is done on a small custom scale...
...In Texas, one-third of new transit and private fleet purchases in metropolitan areas must be alternative fuel vehicles by 1994...
...Put one EV in each multi-car family, throw in all those short-range fleet cars and vans, and you’re talking about a hefty slice of the market...
...Think about it: streets full of softly humming vehicles, not a tailpipe in sight...
...Once this snowball effect gets big enough, perhaps Americans will be able to drive coast-to-coast in natural gas vehicles . . . which means we’d finally catch up to the Canadians, who already can...
...The ideal initial target group for converting to natural gas, for instance, is fleet vehicleswhich consume 20 percent of our road transportation energy...
