Global warming is now one of the primarycauses of natural disasters such as glaciersmelting, the more frequent occurrences of typhoons, droughts and oods, and theextinction of some species of plants andanimals. The excessive burning of fossil fuelto produce energy is resulting in increasedemissions of carbon dioxide, which greatlycontributes to global warming.

Saving 1kWh of electricity is equivalent to

saving 0.4kg of coal and 0.4 litres of purewater, and reducing emission of 1kg of carbondioxide and 0.03kg of sulphur dioxide.

Our environment is changing for the worse.More and more, fossil fuels are burnt tokeep up with the worlds increasing energyrequirement. However, this situation can beimproved if everyone makes a little effort.In this booklet, you will nd some practicalenergy-saving tips.

Tip 9Small-displacement cars savemore energy

As small-displacement carsare fuel-ef cient, competitively-priced and environment-friendlycompared to fancy sports carsor petrol-intensive SUVs, theywill become more popular.

Plus, small cars providemore exibility when it comesto locating parking lots incongested cities.

Small-displacement cars consume__________________ as/than big- displacement cars.

1. the same quantity of fuel2. less fuel

Tip 10Take public transportation toreduce emission of greenhousegases

With more cars on the roads,traf c congestion is boundto worsen. Take publictransportation to avoid gettingstuck in traf c jams and conserveenergy at the same time.

Transporting 100 passengersby public buses occupies only1/10 of total roads (length-wise),consumes 1/6 of fuel and emits1/16 of noxious gases, ascompared to transporting themby cars.

Since public buses are able totransport more passengers, they

__________ more energy compared

to cars.

1. save2. waste
