Yes, using less energy is better, dirty or not. Reducing our dependency on cars also has many other benefits: fewer traffic accidents; reduced parking requirements means more space for people in cities; less sound pollution, which is better for our bodies and for our ecosystems in and around cities; lessen the cost of living by no longer requiring a $15,000 machine as a prerequisite to having a job; increased density means increased foot traffic to small businesses, encouraging healthy competition; increased density can (has the potential to) mean a stronger, more connected community, less segregated by wealth etc. etc. etc.
