Energy - public electricity and heat production. Emissions from the subsector in 2020 decreased by 39.7 Mt CO-e (18.7%) from the peak in 2009, despite continuing population and economic growth. This was primarily driven by a decrease in the total share of generation from coal from 85.7% in 2009 to 68.3% in 2020, and an increase in the share of generation from renewable energy in the national electricity market from 5.8% in 2009 to 23.4% in 2020, with the largest increases coming from wind and solar.
