Just 5% of thermal power plants emit 73% of all CO2 from power generation! This widely reported study ( https://bit.ly/3AziT2k ) is quite stunning. So essentially, if 5% of the 29,000 thermal power plants (about 1500 of them) are given high priority in terms of efficiency increase and emissions reduction, that alone could mean significant CO2 emissions reductions worldwide. Light at the end of the tunnel?
