eople to understand.
Interviewer: And you can tell ordinary families what their carbon footprint is, cant you?
Daren Howarth: Thats right. I work out how much carbon dioxide the familys generated over a year; firstly by studying their bills, then finding out how much waste they produce, how much they use the car, and so on. Adding together all these figures, I calculate their total carbon footprint in tonnes of carbon dioxide. Then I take a look around their home and suggest ways of reducing their carbon footprint.
Interviewer: How do you work out how much carbon each machine around the house emits?
Daren Howarth: By switching off all the things that use electricity, then turning each one on one at a time, you can see the amount of energy each one uses. I use something known as a carbon meter which measures the amount of electricity being used in the house at any one time. It also shows how much carbon dioxide this represents.
Interviewer: Whats the least energy efficient thing youve seen in homes?
Daren Howarth: I go into so many places where I look in the roof and theres no insulation, so theres nothing stopping all the heat just going straight out into the outside air. Insulation massively reduces your carbon footprint; its cheap and the government will help with the cost of it.
Interviewer: So is that the worst thing?
Daren Howarth: Well, central heating systems can be very inefficient and people иье things like electric knives and mixers which are unnecessary, but the thing 1 really cant stand is when people are still using old-fashioned light bulbs. People cant resist them because theyre so cheap, but up to ninety percent of the energy they produce is lost as heat. If you have one, put it in a box and smash it up, so no one else
