Reducing That Electricity Bill - More tips

Lids on saucepans
This may not seem like a big deal, but putting the lids on your saucepans reduces the amount of heat/energy required to, say boil potatoes, to about 1/4 or 1/3 of that needed to do the same without lids. Once the water is boiling you can turn the heat right down. Saucepans with glass lids also allow you to see what is going on without having to remove them.

Use a vacuum flask
If you put to much water in the kettle and end up with some boiling water left over, you can put the remainder into a vacuum flask. Then when you need more boiled water later in the day, you can pour it back into the kettle and possibly add some cold water from the tap. This may at first seem like a waste of time, but the warm water will require a lot less energy to boil than fresh cold water from the tap. Of course ideally it is best to only boil as much as needed, but this isn't always possible since many kettles have a minimum amount of water that should be used with them.
