Unit 4
Global warming
Wind energy is used as power to
produce electricity .
Windmills
where electricity is produced by burning coals.
The coal power stations
in which oil is refined and made pure.
The Oil Refineries
炼油厂
a facility designed to convert nuclear energy into electricity.
A nuclear power plant
on the roof of a house on a bright sunny day are used to collect solar energy, making your house warm or heating your water.
Solar panels
are used to keep back water and raise its level for irrigation or for producing electricity, etc.
The Hydro-electric dams
What are these buildings made of and what is their purpose
They are made of glass and plants can grow in it when it is cold outside.
