There are lots of devices that people are being encouraged to buy, but we need to be smart when we part with our money. A good understanding of what we are getting a why is required. Knowledge is power! Knowing how much electrical energy we are using at home is a great enabler. What better way of getting the message home to your partner / kids / parents etc than actually showing them how much they are using. This is where smart meters come into play. The Eco Home Centre recommends Efergy meters. The E2 meter has the capacity to be linked into your home computer so that you can plot your usage in a visual format.
