Going with alternative energy sources makes philosophical sense for those who choose to do so

From the Winston-Salem Journal:

For people like Ronald Cascio, who fuels his pickup with a soybean-oil derivative, and J.D. Doliner, whose home is partly solar powered, the high price of energy isn't a worry. That doesn't mean their renewable-energy preferences come cheap. In fact, it requires an extra financial commitment to wean one's home or vehicle off fossil fuels. Nonetheless, growing numbers of Americans are embracing cleaner technologies and more energy-efficient lifestyles.
