The unintended effects from halting nuclear power production: Evidence from Fukushima Daiichi accident

This paper provides novel evidence of the unintended health effects stemming from the halt in nuclear power production after the Fukushima Daiichi nuclear accident. After the accident, nuclear power stations ceased operation and nuclear power was replaced by fossil fuels, causing an increase in electricity prices. We find that this increase led to a reduction in energy consumption, which caused an increase in mortality during very cold temperatures, given the protective role that climate control plays against the elements. Our results contribute to the debate surrounding the use of nuclear as a source of energy by documenting a yet unexplored health benefit from using nuclear power, and more broadly to regulatory policy approaches implemented during periods of scientific uncertainty about potential adverse effects.

Automated summary

After the Fukushima Daiichi nuclear accident, the halt in nuclear power production led to an increase in electricity prices, decrease in energy consumption, and an increase in mortality during very cold temperatures. The study reveals a previously unexplored health benefit of using nuclear power, adding to the debate on its role as a source of energy.
