Answers

1. b – £65. According to the Energy Saving Trust, standby accounts for around 10% of the average UK household’s electricity usage.

2. a – PV, standing for “photo-voltaic” (and give yourself a bonus point if you knew that!) PVC is a type of plastic and CHP stands for “combined-heat-and-power”.

3. b – the UK has access to 40% of Europe’s total wind energy.

4. c – A+ or A++ fridge freezers could slash 140 kg off the average household’s carbon footprint and save up to £35 a year, always assuming you don’t already have them, of course – and if you do, score a bonus point.

5. c – it’s nearly 30%; according to government estimates, our homes are responsible for 28% of the UK’s yearly total emissions!

6. b – 270mm is how deep loft insulation should be; it would be a very small tree, and a wind turbine that size would probably fit under your bed!

7. a – amazingly scientists say that growing your own fruit and vegetables for just three months of the year can cut up to a whopping 100kg off your carbon footprint.

8. c – 80%; energy saving bulbs use only around 20% of the electricity used by ordinary ones to produce the same level of light – although the amount of light they give out does reduce as they get older.

9. b – they are called fossil fuels because they were made millions of years ago and contain ancient carbon, although you could argue that (a) and (c) are mostly true too! The word fossil comes from the Latin for “dug up”.

10. c – a third of all the energy used in the UK each year goes on transport.

11. b – 230V.

12 - Give yourself a point for each one.
