Sources of energy: primary and secondary; components of demand and energy mixes in contrasting settings
Countries get energy from different sources, and the particular combination a country uses is called its energy mix. Some energy sources are used directly; others need converting first.
Real World
Germany generates nearly 60% of its electricity from renewables — a secondary energy source — converted primarily from wind and solar primary sources, having phased out nuclear power while still meeting industrial demand through grid diversification.
Exam Focus
Always clarify whether a named source is primary or secondary before discussing it — confusing the two categories undermines the accuracy marks in any energy mix question.
