Coal provides 40% of the world’s electricity, with 75% of this capacity deemed “subcritical”, in other words dirty. That’s a little over 1,200 GW of capacity. The IEA believes that we must shut down 290 GW of subcritical generation worldwide by 2020 in order to stay within a 2°C temperature rise.

In addition to CO2 production, air pollution and the public pressure to close for that reason, is a risk factor. Finally, subcritical plants use 67% more water. Many are in climatic areas where water scarcity is a risk. Continue reading Stranded assets and subcritical coal
