Answers
Answer to question 1 of 10:
answer: C) 14,000 (based on medium sized petrol engine car)
An average petrol car consumes over 14,000 kWh per year; enough energy to heat an average house for a whole year!
Answer to question 2 of 10:
answer: A) 1 (based on average aviation emissions for return trip 5,000 km each way)
You'd need to cut out 1 long distance round trip flight to save 1 tonne of CO2.
Answer to question 3 of 10:
answer: C) 14,500 kWh/yr (based on driving 10000 miles)
A low efficiency car will use over three times the energy of a high+ efficiency car, equating to over 14,500 kWh per year.
Answer to question 4 of 10:
answer: A) 6 (Based on study on fuel used by AC units by NREL)
Just 6 US car drivers cutting their AC use by half could save 1 tonne of CO2.
Answer to question 5 of 10:
answer: B) 10 (Based on 500 km journey e.g. London - Edinburgh).
It would take 10 return trips on the train, instead of 1 short haul flight, to save 1 tonne of CO2.
Answer to question 6 of 10:
answer: B) a year (based on average charger data from Nokia)
If 65 people unplugged their mobile phone chargers when not in use for a year, it would save 1,000 kWh.
