It helps the poor (at least in urban areas) and provides a basic social need. In addition it is environmentally sane.
How would those subsidies encourage people to drive slowly? To share a ride? To take a bike and do entirely without fuel? To better insulate their houses and burn less oil for heating and air conditioning?
My point is that energy efficiency comes from a large mix of measures. (I agree that these measures will probably include inreasing the number of busses and trains.) In theory, legislatures can help bring about the optimal mix through clever subsidizing and rationing. But in practice, it requires that the legislature know what the right mix is, and that it implement it in spite of fierce lobbying from oil and car companies. High prices, by contrast, encourage everyone to look for ways of conserving energy. They instantly rewards anyone who finds a new way and makes it happen, whatever it may look like. Their effectiveness does
not depend on any small group of people being geniouses or saints, or even especially decent.
As I said in my last post, the poverty aspect is difficult, and it needs a workable political solution. But on the specific problem of conserving energy, the best option for society is that the government do nothing.
