German use of coal to generate electricity has declined steadily from 1990 to 2011, according to readily available statistics on the German electricity system. The percentage of coal-fired electricity in German electricity generation has fallen from 56.7% in 1990 to 43.5% last year — a decrease of more than 10% despite a increase in total electricity generation during the same period of about 10%. At the same time the share of renewable energy in the electricity mix has increased from 3.6% to 19.9%, mostly due to the rapid development of wind energy and biomass.
