my prediction is that as soon as we have all become green citizens and switched to hybrid cars, the use of coal for alternative fuel will result in the price of electricity skyrocketing! the sensible solution is a combination of conservation and preparation. use less and also start preparing to find more, both drilling and alternative methods. i have found on my long road trips (of which there WERE many) my trusty ford taurus gets 37 mpg instead of the usual 28 when i slow down from 75 down to 60 mph....what's the hurry?
