The driving experience I'm looking for in the Volt is driving by a gas station sign that says $7/gallon with a big old grin on my face. – LampCord, member at gm-volt.com/forum
A problem with renewable energy is that some forms are intermittent. E.g. wind doesn't blow all the time – on land. But, travel just 20 miles (32 kilometres) off shore, & the wind blows at a constant 33 feet per second (10 meters/sec, 36 km/hr, 22 miles/hr).
