We expend energy to do work. That’s sort of a principle of physics. When an automobile engine burns gasoline, the idea is to move one or more persons from one place to another in a car. But when the car sits in traffic, engine idling, energy is being expended without accomplishing work. It’s wasted. Yet we’re addicted to our automobiles for several reasons. One, for that so-called sense of freedom. Another, because there aren’t always alternatives. And even when there are alternatives, many people still choose their cars.
For too long, support for public transportation in many areas has been grudging. Often decent mass-transit systems are impractical, simply because of the nature of our sprawling growth. Populations are no longer concentrated in a way that can be well served by bus and light rail systems. And if it’s impractical in many suburban areas, it’s certainly even less practical in rural sections of the country.
But where it is practical, public transportation should be expanded and made even more attractive an alternative to automobiles. And future planning should make public transit a high priority for communities of the future.
When public transportation does exist though, how can it be made more appealing than the private auto? One way is to make it cheaper to take a train or bus than to drive a car. If this means subsidies (and it surely will), so what. Another way is to make it far-reaching and timely. If people spend less time getting to their destination on a bus or train than they would in their car, they might be more inclined to regularly choose that option. Getting more people out of cars and into public transportation in cities and densely populated suburban areas would go a long way toward reducing greenhouse gases and energy consumption.
Once again though, it requires leadership at the top to get people behind public transportation. Right now we don’t have that kind of leadership. And once again, it requires the kind of leadership willing to fund public-transit alternatives. It might be expensive, but it’s a step that needs to be taken if we’re going to become energy independent and slow the rate of global warming.
