CAMBRIDGE, MASS.—By 2030, the people of the world will be driving as many as two billion cars—up from 700 million today—according to John Viera, director of sustainable business strategies for Ford Motor Company. Whether those cars are plug-in hybrids, hydrogen fuel cell vehicles or just supremely efficient internal combustion engines, the economic, environmental and social impacts will be huge—from lithium mining in Bolivia to road rage in China.

If your wallet is taking a beating from high gas prices and all this talk of green energy has inspired you to shop around for a hybrid car, new fuel-efficiency ratings may help you.
The Environmental Protection Agency (EPA) has ranked 10 hybrid vehicles. Topping the list: the Toyota Prius, which gets 48 miles (77 kilometers) per gallon on city streets and 45 mpg (72 km) on the highway.
The Honda Civic Hybrid is next, racking up 40 mpg (64 km) for city driving and the same as the Prius on the freeway. No. 3 is the Nissan Altima Hybrid, which takes you 35 miles (56 kilometers) per gallon in the city, 33 miles (53 kilometers) per gallon on the expressway.

In a time of rising gas prices (well, actually falling at present but still more expensive than last year), many consumers are searching for ways to cut fuel costs. One eye-catching options appears to be so-called water for gas, turning the H2O from your tap into an endless fuel source.
But you'd better not put said water directly in your gas tank. That's a quick way to kill combustion in your internal combustion engine and earn a trip to the repair shop.
That's not what these outfits are peddling of course. They're selling kits that allow people to electrically or chemically separate the H2 from the O in water and then use said H2 as a fuel additive. And one man in Norfolk has used such a kit to extend the range of his Chevy Avalanche.
