SALEM — A bill introduced in the House would allow more gas stations to offer self-service pumps. Oregon and New Jersey are the only two states in the Union that don’t allow self-service gas stations statewide.

In two generations, Oregonians might drive along freeways and not see a single industrial smokestack. They might instead see solar panels or wind turbines. And they might see them from an electric vehicle. That’s the goal of Oregon politicians trying to pass legislation to charge companies for polluting.
