Technicians in Japan have reopened their first nuclear reactor since Fukushima was shut down in 2011. A cause for growing concern is Japan’s increasing use of coal. Prior to Fukushima, 29% of the country’s electricity generation came from nuclear, but since then it has nearly been replaced entirely by coal. According to Politico, it seems like a short-term response to the nuclear crisis but it’s not. Japanese utilities are in the midst of replacing many of their aging coal power units with more efficient ones. Further, they are promoting their ‘efficient’ coal-burning plants globally to entice other companies to invest.
