microwave usage????

Question

we use our microwave alot at home could this be the cause of our high electricity bill?how much does it cost to run a microwave each time we use it?ps i live in australia.....

Answer 1

Probably not.
If it's an old microwave, it might be using some extra electricity, but in general, microwave ovens are pretty efficient. They are a lot less to run than a oven that does the same thing. The newer smaller microwaves and convection units are really efficient.

Many other items use more electricity. Major problems are anything with motors and either heating or cooling.

Look at your refrigerator, a/c, water heater, etc. first.

Answer 2

Microwaves are typically 500-750 watt devices. Electricity in the US is charged by the kilowatt hour. So a 500 watt microwave 6 minutes( 1/10 hour) will consume 500 * 1/10 watt hours = 50 watt hours = 0.05 kilowatt hours. 1 kilowatt hour in the US is about $0.10 or 10 cents so 0.05 kilowwatt hours cost is $0.0010. So for a 500 watt microwave, 1 hour of operation would cost about $0.05 or 5 cents in the US You will have to adjust these numbers for the Australian ratesand your microwave power rating, but this gives you the foundation for the calculations. I don't see how your microwave could be causing high electricity usage, even if you used it 6-7 hours per day.

Answer 3
