5 All building in Sweden will be heated by solar energy in 2050

II While - listening:

- Ask Ssto listen and then check their T/F statements.Ask Ss compare the answers with a friend

- Ss listen again if necessary Feedback and give the correct answers

2 Write it up: (optional)

Students write about energy, using the ideas discussed above and the two exercises (a+b) on page 60

*Tapescript: Are you looking for a cheap,clean,effective source of power that

doesn’t cause pollution or waste natural resources? Look no further than solar energy from our sun.At present, most of our electricity comes from the use of coal,gas, or nuclear power.This power could be provided by the sun.One percent of the solar energy that reaches the Earth is enough to provide power for total population Many countries are already using solar energy Solar panels are placed

on the roof of a house and the Sun’s energy can be stored for a number of days, so

on cloudy day you can use solar energy too Sweden has an advanced solar energy program There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015
