Energy Saving Tips: Appliances
Comparing energy use by efficiency for a tall unit:
|Annual kWh Use||Daily kWh use|
Comparing energy use by size for an A rated fridge
|Cubic Feet/Litres||Style||Annual kWh Use||Daily kWh Use|
|8.2/232||Under Counter Unit||292||0.8|
We have to keep things clean but follow these handy tips to make it as energy efficient as possible:
– Use the ECO settings or turn the temperature of the wash down
– Make sure you put in a full load each time
– Pre-soak or treat any stains or especially soiled clothes
– Switch the machine off at the wall between washes
4 hours use per week = £100 per year
Buy a covered external rotary dryer for £100 and dry outside all year every year!
How many minutes used in one day –
If you have 4 cups of tea every day (for one year) and it takes 2 minutes to boil the kettle 4 x 2 minutes = 8 minutes
How many hours in one year-
8 minutes x 365 days = 2920 minutes
2920/60 (minutes in an hour) = 97.34hrs
How many kilowattts would that be –
Example kettle uses 2 kilowatts every hour 48.67 hrs x 2kW = 97.34kWh
How much would that cost-
It costs about £0.145 per kW
97.34kW x £0.145 = £14.11
How much if you boil 3x more than needed –
£14.11 x 3 = £42.33
Wasting £28.22 every year and releasing an extra 116kg of CO2 into the atmosphere
– Draw a mark on your kettle which you know represents 1-2 mugs worth of water so you don’t overfill it.
How Water Bottle v Electric Blanket
Boiling a 2kW kettle for 2 minutes = 70Watts (0.07kWh)
Electric blanket on for 10 minutes = 10-30Watts (0.01kWh – 0.03kWh)
Many electric towel rails just have on/off switches- but why heat your towels all night long? Have a timer attached to limit the amount of energy use.
– One rail on for 30 minutes of every hour will cost £190 per year and would require 643kg of coal to be burnt to create the required electricity.
