Electricity works everywhere(p46)
Almost everyone today uses electricity in one way or another. It is hard to imagine what life in our cities would be like without it. Electricity lights streets and buildings, and warms people and animals. It heats food in cookers and cools it in refrigerators. It drives trains and works traffic lights and lifts. It also works the machines in factories that make all kinds of goods. Everyday wonders such as computers and televisions use electricity to bring entertainment and news to millions of families. In villages and on farms, electrical machines milk the cows and chop their food. They also cool the milk and churn① the butter. Indeed, electricity finds as much work to do in the countryside as it does in the cities.
