In succeeding decades, nuclear power costs declined, but the industry remained heavily dependent on subsidies. And in recent years, the investment cost of developing new nuclear plants ballooned from $2,065 per kilowatt in 1998 to $5,828 in 2015, according to a World Nuclear Association report.

All of this bodes ill for the future of nuclear power. But the failure for nuclear to live up to its potential should hardly surprise us. It began as an idealistic attempt to domesticate the bomb in peacetime; the actual economic cost and benefits of doing was a secondary concern at best.

The world has spent nearly sixty years trying to make economic sense of nuclear power, with limited success. It may be time to pull the plug.
