Save Energy on your next Cuppa!

teaDid you know that you can radically reduce energy consumption by boiling only the water you need?

If you’re looking for energy saving kettles, you probably don’t need to look much farther than your own kitchen. Here are some of the key things you can do to turn ordinary kettles into energy saving kettles, without rushing off to the store to buy a new one:

Use an electric kettle, not a stovetop kettle. An electric kettle will be more efficient than a kettle you put on a stovetop, because much of the heat from a stovetop burner escapes around the sides of the kettle. So using an electric kettle is better than using a stove-top kettle on an electric stove, and is probably more energy efficient than using a stove-top kettle on a gas stove as well.

Buy the right size kettle. Only boil what you need. If you’ are making a four-cup pot of tea, only put four cups of water in the kettle. There’s no point boiling more water than you need. It will take longer, and it will use more energy. So measure carefully.

Get a small kettle is you usually only boil for one or two cups. Larger kettles have a minimum fill level required to cover up the heating element which might be more than the hot water you need.

Use the hot water right away.  Don’t get sidetracked.  The kettle boils and then shuts off.  Ten minutes later and you will have to boil the water again since the water is no longer hot enough.  This is a waste of energy to bring a kettle to the boil twice

Make sure everything else is ready before the water boils.  Don’t wait for the water to boil, then start setting up the coffee-making or tea-making ritual.

Look for energy saving kettles that let you know when the water has boiled. Old whistling stovetop kettles definitely qualify as energy saving kettles when it comes to forgetful people: it’s pretty hard to leave one of them boiling for very long.

Look for insulated energy saving kettles with an insulated shell, especially if you drink a lot of tea or coffee.  These kettles will keep more of the heat inside the kettle so that the water lasts longer before it needs to be boiled again, or takes less energy to come back to the boil.

Save the extra hot water. If you do boil too much hot water, use what’s left. Leave it in the kettle – someone else might want to use it.  Or put it in a thermos so it keeps really hot. Or pour it in the sink when you’re doing dishes. Above all, don’t pour hot water down the drain in winter – you’re just throwing away perfectly good heat and water.

There’s really not much more to energy saving kettles than this: boil only what you need, use it right away, keep it hot in a thermos without using more energy, and be at hand and at the ready when the kettle does boil. If you strive to do this, then all the kettles you come across will be energy saving kettles. And if you’re looking for a new energy saving kettle, just buy one that’s the right size, is electric, has an automatic shutoff, and, if you get easily sidetracked, reminds you loudly when the water has boiled!
