Those sources are now drying up, and a new demand-driven peak may be on the horizon.
The Fukushima Daiichi disaster in Japan last year scaled back global nuclear ambition dramatically and raised questions about nuclear power's future. That makes peak uranium an uncertain risk at a time when other power sources, such as solar, wind and natural gas, have made great gains.
