Read the article and put the paragraphs A–F in the correct order. The first paragraph is given.

Scotland’s Super Eco-Pensioner
A But Maureen’s energy-efficient lifestyle doesn’t just involve not travelling in vehicles. Another way in which we consume energy is in heating our homes, and so Maureen has stopped doing so. She won’t switch on the heating, even in winter. So how does she manage to keep warm? She just puts on another layer of clothing or does half an hour of exercise. Maureen doesn’t waste any fuel in cooking either. She eats only raw, vegetarian food. She lives on fruit, vegetables, seeds and nuts. She stopped eating meat when she discovered how the beef industry damages the rainforest. Now she has got so used to her low-fat, high fibre diet that she can’t imagine returning to the normal cooked food that most of her neighbours eat. [ ]

B Maureen McDonald is 65 years old and hasn’t caught a bus in nearly 40 years. Nor has she travelled by car, train or plane. She made the decision to stop using any form of motorized transport, not because of any fear or phobia, but because she wanted to live a more environmentally friendly lifestyle. According to Maureen, the people of the world use too much energy. Globally, we use more resources than the planet can sustain, and we must either reduce our consumption or destroy our planet. [1]
C Despite these strong convictions, Maureen’s lifestyle is not completely zero-energy. She has to admit that she does use some electricity – but only a very little. She has one low-energy light bulb and a radio. She got rid of her television 20 years ago, and she doesn’t miss it. She thinks that almost everything on TV is rubbish. [ ]

D So how does Maureen get around, if she can’t travel on wheels? Simple - she walks or runs whenever she needs to go anywhere. From her small flat in the suburbs of Edinburgh, it takes her just under an hour to reach the city centre. It’s not always pleasant – the weather in Scotland is often very wet – but Maureen certainly keeps very fit. She doesn’t have to worry about being overweight like many people of her age. So where does Maureen go for her holidays? Well, obviously not the sunny beaches of Spain. If she feels the need to go away for a break, she simply walks off into the Scottish countryside. [ ]

E Maureen has one more electrical appliance that she likes to use – an electric kettle. She uses it to make hot drinks, which she enjoys immensely. She also uses it to make hot water for washing. She usually tries to wash in cold water, but once in a while she allows herself the luxury of hot water, especially in winter when the temperatures in her flat can be freezing! “It takes a lot of discipline to live this way,” she says, “But I couldn’t change now, even if I wanted to!” [ ]

F So no heating! Raw vegetables! What does Maureen hope to achieve by living the way she does? After all, one person can’t save the planet single-handedly. What difference can she make, if everybody else continues to consume more and more energy? According to Maureen, she wants to lead by example. She wants to prove to the world that it is possible to live well without burning up the world’s natural resources. She sees her life as an experiment to show people an alternative. [ ]
