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.
3. Divide the result by 1,000 to convert watts to kilowatts. So for example, if your large window fan is rated at 250 watts and you use it 5 hours a day, its kWh use per day is 250 (watts) * 5 (hours used per day) / 1,000 (to change watts into kilowatts) = 1.25 kWh per day. 1  4 Edit step.
