4. LISTEN
a) Listen to the news on solar energy
and decide whether the statements

are true or false. Check (√) the
boxes and correct the false
statements


“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, oil, 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 the total population.


“Many countries are already using solar
energy. Solar panels are placed on the roof
of a house and the Sun’s energy is used to
heat water. The energy can be stored for a
number of days, so on cloudy days 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
power instead of gas by the year of 2015”
