Everything about Alison Gannett is green, from her straw-bale house to her solar-powered appliances. But when you're as serious about curbing carbon as she is, a mere hybrid won't do. That's why she spent $35,000 to install an extension cord on her Ford Escape Hybrid.
She is among a small but vocal -- and growing -- number of people who aren't waiting for automakers to deliver plug-in hybrids. These early adopters are shelling out big money to have already thrifty cars like the Toyota Prius and Ford Escape Hybrid converted into full-on plug-in hybrids capable of triple-digit fuel economy. "I love watching the mileage go up," says Gannett, a world champion extreme skier and dedicated eco-evangelist. "The highest I have gotten is 232 mpg. I average around 80-100 mpg."
