Our enormous investment in highways, airports, cars, buses, trucks, and aircraft is almost completely dependent on oil, and it will be significantly handicapped by higher fuel prices, and devastated by actual fuel shortages. The electrification of road-based vehicles is a must and will require at least two decades to fully deploy and we must move to Earth-gentle electricity generation to charge the vehicles. Meanwhile, existing private automobiles must be put to use more efficiently through carpooling, car-sharing, and ride-sharing networks.
