The Europeans just enacted a carbon tax on air travel. The auto carbon tax won’t be far behind if we are to have any chance of preventing the melting of polar ice caps. Try selling Expeditions, Yukons and Hummers when you’re paying $5.00/gallon plus a carbon tax. It’s coming, folks. The writing is on the wall.
Plug-in hybrids offer the best chance of transitioning away from fossil fuels towards a renewably powered transportation future. Full sized electric vehicles suffer from limited range and may require up to 3 times the battery capacity of an EDrive equipped plug-in hybrid and still not be capable of satisfying 100% of a person’s driving needs. At present, hydrogen fuel cell powered vehicles suffer from astronomical cost (over $500,000), limited range (80-180 miles), low efficiency (compared to batteries) and most notably a lack of economically priced and widely available fuel. Plug-in hybrids however can be built today and provide a no-compromises solution that moves us away from fossil fuels.
