Riding the train in to work Tuesday, I caught sight of a plume of smoke rising from the horizon. A large fire, I later learned, was underway at a major Chevron oil refinery just northeast of San Francisco. No one was seriously hurt, but upwards of 500 people went to the hospital with respiratory complaints, while several thousand were told to stay in their homes.

Following the news of the fire, I haven’t been able to stop thinking about the relationship between health and energy. It’s not an issue that gets much airtime in energy debates. But when we start to look into the health problems our current system is creating and how far existing clean energy technology could go in saving lives, the implications are huge.
