Considering all of the errors and mistakes government makes, the post about A Flock of Seagulls seems to be a perfect case of the pot calling the kettle black. (Not to mention that there is no such animal as a seagull).
An electric heater rated at 1000 watts (1 kilowatt), operating for one hour uses one kilowatt-hour (equivalent to 3.6 megajoules) of energy. A television rated at 100 watts operating for 10 hours continuously uses one kilowatt-hour. A 40-watt light bulb operating continuously for 25 hours uses one kilowatt-hour.
Watt(W) is unit of power and 1000 watts equals 1 Kilowatt (Kw) .Kilowatt hour (Kwh) is the unit of energy consumed which the unit charged in the electricity bill. If you are using 1 Kw power ( sum of all loads including lights/fan TV etc., if switched on and working at the same time) for one hr your consumption will be 1 Unit.
