Find out how much energy you consume
Given below is the energy consumption of our daily household gadgets – ranging from the innocuous mosquito repellent to energy guzzler like a kettle or a geyser. Check how much you use on a monthly basis. It will help you save on precious power.
Did you know that:
- A computer monitor left on overnight wastes enough energy to laser print 800 sheets of paper?
- A photocopier left on overnight wastes enough energy to make 5300 copies?
- A Low Energy Lightbulb uses 5 times less electricity than an ordinary bulb and lasts 10 times longer?
Now you can make your own list…whether it’s to find out how much you spend by running that huge refrigerator and air-conditioner, ironing your own clothes, or to save on the energy costs of running your washing machine….for example if you buy a model which does not automatically heat water, you will save a lot on electricity. This chart will give you everything – information on your innocuous ceiling fan to a toaster, immersion rod, hot plate, mixer, vacuum cleaner, tape recorder, video player (VCD) and yes even mosquito repellent and Night Lamp!
To read the chart: The column on the left which says ‘Wattage‘ is one which tells you the wattage of your appliance and this is usually found on the appliance itself. This determines how much electricity you consume. For example a 25 watt bulb, if used for just 1 hour a day for one month (monthly use) will consume .75 KWh (second column gives this figure) and it will take 40 hours to consume 1 whole unit (third column) =1000KWh. As the electricity company charges you per unit, this is what you need to know to calculate how much it costs you.
1. Wattage ratings differ from model to model
2. Electricity is measured in Kilowatt Hours (kWh) and is calculated by multiplying the watt rating by the number of hours the machine runs and dividing this by 1000
3. When 1000 watts are used (also called IkWh of electricity), 1 unit of electricity is consumed. (1 kWh=1 unit of electricity)
