Coal-fired power stations are polluting whereas wind power is non-polluting. Which of the following is one explanation why wind power has not replaced coal power despite its advantages.
Wind power is a free and sustainable source of energy.
Coal power stations can only be built in certain locations.
You need a lot of wind turbines to generate the same power as a coal power station.
Wind turbines have to be built out at sea to be most effective.
The table shown gives information about various methods to generate power.
An electricity supply company has enough power stations to cover demand except when the weather is unusually cold. During very cold weather the demand can suddenly increase by as much as 20 000 MW.
Which types of power station is best suited to meet this demand? Check all boxes that might apply.
Wind Farm
Gas Turbine
Tidal Scheme
Nuclear Power Station
Coal Fired Power Station
