Starting in 1971, I became a card-carrying member of the “nuclear priesthood.” I began as a licensed nuclear reactor operator and progressed through the industry to become a senior vice president. I believed, with religious fervor, that by helping to build and operate atomic power reactors, I would be creating power that was “too cheap to meter.” The historic 1973 gasoline shortages and long lines of cars queued at the pumps made it clear to me and hundreds of other nuclear engineers that nuclear power was the only solution to the “energy shortage.” In the 1970s and ’80s, solving this apparent energy shortage was our only mantra. At that time, there was no scientific data connecting fossil fuels to climate change.
