After a report earlier this week claimed that Gwen Stefani was pregnant with twins, gossip debunking site Gossip Cop slammed the report and called it false.
Best Answer: A microwave oven putting out 900 watts consumes around 1500 watts. One unit of electricity is 1 kilowatt-hour, so a 1500 watt appliance will use 1.5 kWh or 1.5 units. Electricity is about 7p per unit, so it will cost around 11p to run it continuously for 1 hour.
A simple equation to work out how much running an appliance costs you: Wattage x hours used per day / 1000 = daily kilowatt usage. (1 kilowatt hour = 1,000 watts). As an example, our kettle takes 2,200 watts to run. Assuming that I boiled it (full) for a total of 1/2 hour per day it would use 1.1 kilowatts per day.To work out the cost, multiply the kilowatts per day by the cost per kilowatt hour as per your electricity bill. According to our latest electricity bill, our electricity costs $0.17130 per kilowatt hour.So at 1/2 hour per day, it costs us 19c each day to boil the kettle.ccording to our electricity bill we pay $0.17130 per kilowatt hour, so this appliance would cost us $86 per year or $0.23 per day to run. Apart from the energy rating sticker, most appliances have their wattage printed somewhere on them so you can work out how much they cost to run.
