　　Sweden is country which imports seventy percent of its energy. Its people are very 67of the cost of energy and the importance of not wasting it. In Uppsala temperatures are frequently 68zero degrees Celsius. There, a man has built a house which case he pays only twenty�瞗ive pounds a year to 69. The reason for this is insulation. In this it

　　means placing material70 the inside and the outside of the walls of the house to keep the cold71and the warmth in. There are five hundred

　　millimeters of insulation in the 72and three hundred millimeters of insulation inside the walls. All the windows have four panes of glass. The house is heated by the body heat of the people inside it, and by the heat from the lights and other 73in the house.

　　In the UK there is less waste now than 74. In 1980 the country used eight percent less energy than in 1973, 75there could still be a saving of thirty percent in industry and around forty percent in ordinary 76use of energy.

　　However these renewable forms are often expensive to 77, and there are problems. Solar

　　energy, for example, is not always 78because the sun moves about the sky and there are many days 79the weather is very bad.

　　There is one source, however, which may become 80important. This is geothermal energy,

　　or heat from the 81of the earth. The temperature of the earth increases thirty degrees Celsius 82each thousand meters in certain parts of the

　　world. At six kilometers, 83, it rises to nearly two hundred degrees. To remove the heat, water would be pumped down into the rocks and back up to the 84. Heat from the earth is already used in certain parts of Iceland and New Zealand.

　　When we have learnt how to use it properly, the earth itself, 85 with the seas, the wind and

　　the sun will 86 certainly provide with all the energy that we shall ever need.
