Question

17．Walking，cycling or hopping on to public transport are the best ways to travel with a clean conscience．Yet cars remain an important option for many families because of its convenience．For people in rural areas，or with mobility problems，a car can be an essential lifeline．
Drive with style
No matter what kind of car you run，the least reliable part will be you：your driving style has a massive impact on the fuel needed，with acceleration，gear-changing and braking all playing a significant role．
Inching along at the pace of a child's tricycle might feel frugal but won't magically yield peak economy．In most modern cars，accelerate normally，changing up at 2，000rpm in a diesel，or 2，500rpm in a petrol-powered car．Once at a sensible steady speed，choose the highest gear that will let the engine run without labouring．
A number of eco-driving apps are available for smartphones，to help you improve your smoothness．The A Glass of Water iPhone app offers tips to help you avoid spilling a drop．The free RAC Traffic app is also a great way to avoid wasting fuel in traffic jams．
It's also important to：
●Check tyre pressures once a month．
●Leave junk at home．Carrying extra weight in the boot wastes excess fuel．
●Leave in good time and don't speed．An extra 10mph on the motorway will add 10% to your fuel bill．
Power plays
It may be decades before alternative fuels such as hydrogen become commonplace，but hybrid cars that use battery power to boost a petrol or diesel engine are already available in every category．It means many families might find an electric vehicle ideal as a second car．
Sell your wheels，still travel by car
If you need a car for short periods，such as shopping，and live in a city，then consider a short-term car-hire service such as Zipcar instead of owning a car．If you're travelling longer distances，pay your share of the fuel costs to someone who's already driving there．
