Energy Energy Saving Carbon Temperature

We’re all aware that we need to be saving energy, lowering our bills and cutting our carbon footprints – after all we’re constantly being bombarded by information and adverts to remind us to do our bit.

The only problem is that for many of us, with such a range of facts being bandied about, it can sometimes get a bit hard to keep track of them all.

Do low energy light bulbs, for instance, last ten times longer than ordinary ones and save around £40 over their lifetime – or will they save me a tenner and last 40 times as long? Or is it that they’ll each cost me £40 to buy?

Confused, or do you see yourself as a bit of an energy expert? Try this quick quiz and find out how much you really do remember.

    4. (c) 270mm.

    5. (b) ‘G’ rated products are the least energy efficient.
