Gas-fired power stations provide electricity for homes and industry.
A government decides to replace a gas-fired power station with a tidal barrage power station.
Describe how electrical energy may be obtained from the gravitational potential energy of the water trapped behind a tidal barrage.
Apart from cost, state two advantages of generating electricity using a tidal barrage power station compared with using a gas-fired power station.
Apart from cost, state two disadvantages of generating electricity using a tidal barrage power station compared with using a gas-fired power station.
