Economic depressions in 1929 (Wall street crash) and 1979 (related to OPEC oil price rise)
rapid economic growth in 1960s
"great leap forward" in China 1950s
burning oil wells in Middle East during 1991 Gulf war
collapse of the USSR leading to closure of heavy industry (also in east europe)
effect of weather variation on renewable energy supply (wind and hydro) in Denmark.
