| Comment | The electricity boards back in the day insisted that power stations be optimised for electrical power generation which means the waste heat is too low grade to be used for district heating and is literally thrown away. If the thermoelectric efficiency had been reduced just slightly then the waste heat would have been suitable for district heating, none of it would have been thrown away and the overall system efficiency would have been much higher.
