An island nation decides to transition its electricity grid away from coal-fired power stations to renewable energy sources.
State two environmental problems caused by burning coal, other than contributing to global warming.
The nation decides to build a tidal barrage power station across an estuary. Describe how a tidal barrage generates electrical power.
Tidal barrages are expensive to construct. State two other disadvantages of using a tidal barrage power station to generate electrical power.
Because tidal energy generation is cyclic, the nation needs to store excess electrical energy during periods of high generation. Suggest one large-scale method of storing this electrical energy.
