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.
2) Run it for a month and see how much your bill increases. 3) Find out your electric rate. Typically it's 9 or 10 cents per kWh (Kilowatts per hour). That means if it's 1000 Watts and running all the time it would cost 10 cents times 24 = $2.40 per day.
