Sri Lanka used to rely on hydro, with oil as a backup, and has added a lot of coal.
I wonder how many other countries are increasing non-renewable output?
Not increasing but cancelling plans on phasing out. Here in The Netherlands, an absolutely minuscule country of ~18 million people, two coal plants will remain online that previously would've been phased out.
Sri Lanka has only one coal power plant (construction began 2006), and the later coal project was canceled.
