HOST: Have you ever wondered whether wind and solar plants should be located to best lower air pollution? On this week’s Energy Bite, Jay Apt, a professor at Carnegie Mellon University, has some answers.
APT: We all know that the sun shines most in the southwest part of the United States and the wind blows the most in the Great Plains. But that doesn’t necessarily mean that is where you should locate wind and solar plants.
If your objective is to decrease polluting power sources, you should locate the wind and solar where we have existing high pollution electric power sources. And thus increase the share of renewable power. In many cases, the renewable power can be less expensive than, let’s say, building a new coal plant in the Ohio Valley.
HOST: Can you give an example of how this might work?
APT: Some years ago, New Jersey passed incentives that have tremendously increased the amount of solar power in that state. I thought initially that was not an effective policy, because the sun does not shine as much in New Jersey as say it does in Arizona. But I came to realize that in New Jersey, solar power was displacing some old oil power plants and so it was a cost effective power that significantly reduced pollution.
