I hate to say it but based on this source it looks like global power sourced from coal power has gone UP every year since 2011. I found this source on google and am know nothing about its political agenda, however the slider it provides to see total coal power by year seemed very handy.

2011: 1.679 .MW 2012: 1.740 .MW 2013: 1.799 .MW 2014: 1.848 .MW 2015: 1.917 .MW 2016: 1.969 .MW 2017: 2.002 .MW 2018: 2.018 .MW 2019: 2.044 .MW

The growth appears to be coming from new plants coming online in each of those years primary in India and China.
