Local Governments Can Lead the Way, Even on Transportation

''Sustainable biofuels from waste materials or second generation feedstocks like cellulosic ethanol and jatropha or algae biodiesel are very promising, as they can be used in many of today's vehicles with only modest changes to infrastructure. If any of the hundreds of companies working on sustainable biofuels can produce fuels that use marginal land with little water, energy and other inputs, this option may become very important. It's clear that corn and soy, while useful for maturing the market and deploying infrastructure, have limited ability to solve our liquid fuels shortages without negatively impacting our environment and social fabrics.''
