The “energy transition” from nonrenewable energy sources to a sustainable-power economy.
Update on 16 Jul 2013: After Germany began its phaseout of nuclear power by shutting down eight of its seventeen nuclear power plants in 2011 and yet was a net exporter of electricity in 2012 e.g. to France, which kept its nuclear power plants but suffered brownouts, German utility companies are now indicating they are considering shutting down dozens of coal and gas power plants as well because they are not profitable enough in the current renewable energy boom. Power plant operators want to be paid by the government for keeping the power plants available as backups, despite supply-driven reductions in their electricity selling prices. The Bundesnetzagentur can however force them by law to keep the power plants restartable, sans compensation.
