I've written before here and in STANDPOINT magazine about the Greenhawk Movement. I should also have mentioned a like-thinking organization - SET AMERICA FREE. They're "a coalition," according to their website, "of tree-huggers, do-gooders, sodbusters, cheap hawks, and evangelicals."
They advocate American taxpayers providing $12 billion of incentives for auto manufacturers to produce, and consumers to purchase, plug-in and flex-fuel hybrid vehicles.
They advocate a mandate to incorporate plug-ins into the US government transportation fleet.
They advocate incentives to transform fueling stations to serve all liquid fuels for flex-fuel vehicles.
They advocate government policies to encourage mass transit.
