Energy Monitors
Do you know which appliances in your home or office use the most energy? Energy monitors can help you find out.
Energy monitors show you in real-time how much electricity your home is using, when you turn on a light or other electrical appliance they display shows the change in load. Many energy monitors also show the cost of electricity being used.
Energy monitors range from devices which plug in and monitor a single lamp or appliance – good for really working out how much electricity your TV uses, for example – to those which connect to a computer and allow you to see graphically how much energy you've been using.
The chart shows how much electricity was used while baking bread – you can see how the oven uses a lot of energy as it heats up and then the thermostat turns the electricity on and off to keep the oven at the right temperature. The two big spikes show when a kettle was used while the bread was baking.
It's been estimated that almost £1 billion is wasted each year by leaving appliances on when they're not being used and energy monitors can help reduce this.
