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.

Energy Monitor Log of Oven

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.

Insulation and Draught-proofing

 


The illustration  above shows the Nottingham ecohome where almost everything that can be done to improve insulation and draught-proofing has been done, and lots of other energy-saving measures put in place too. But we don't need to do it all at once.

Cavity wall and loft insulation can make a big difference to the heat your home loses. Loft insulation can be done as D-I-Y (although you do need to think about any pipes in the loft, and make sure there is enough ventilation to avoid condensation problems). Cavity wall insulation is a bit more tricky and really needs a specialist to do it.

If the walls of your house don't have a cavity then they can still be insulated – and the savings will be even greater – but installing the insulation will be a bit more tricky. Solid walls can be insulated on the inside or on the outside and there are pros and cons for each approach.

Double glazing windows although expensive makes a big difference to the amount of heat that escapes from your home. Draught-proofing windows and doors, filling any gaps in the floorboards and sealing gaps in the skirting will also make a big difference. Insulating under the ground floor is a bit more complicated but also makes a difference.

There are a range of grants and other schemes available to help with insulation and draught-proofing, the Energy Saving Trust has an online database which shows what help is available in our area for different types of insulation and draught-proofing, as well as for heating and renewable energy. Visit their website at http://www.energysavingtrust.org.uk/ for more details

Finally, there are those somple things you can do without spending any money at all, things like closing curtains and blinds after dark help keep heat in.
