Most are surprised that Las Vegas has the highest percentage of alternative fueled vehicles in its city fleet--more than 60% of its vehicles are burning biodiesel, or compressed natural gas or are hybrid electric. SustainLane Goverment released yesterday this ranking.
The top other cities are as follows:
3. Kansas City, MO
8. Los Angeles
10. Portland, OR
These cleaner-fuel vehicles cut air pollution locally, but they also reduce carbon emissions that cause global climate change. They push further development of clean technologies that are likely to be rolled out to consumers, and, alternative fuels provide economic opportunities for regional farmers producing fuel crops--or better still ag by-products that can be used as to make fuel, such as used cooking grease. My latest favorite biofuel is bio-butanol, which is way more efficient than corn-based ethanol, and can be made from a variety of crops.
Final footnote: two of these cities, Denver and Albuquerque, vow to implement 100% alternative fuel fleets by the end of 2007 or so.
