The infamous term “three-day week” was coined during the 1984 “winter of discontent” when the UK coal miners went on strike. Gittus thus unwittingly highlights that fact that domestic energy resources need not necessarily outperform imported energy resources in their contribution to the security of energy supply. His own statistics confirm that the longest significant energy supply interruption in the United Kingdom was precisely due to the 1984 strike (Gittus, 2004, p. 5).
