8.1 Renewable and non-renewable resources
Anything that people find useful is a resource. Human resources include labour, machinery
and money. Stone, water, soil and timber are natural resources, because nature provides
them. Some natural resources will never run out, and we call these renewable. Other
natural resources will run out some day, and these are non-renewable.

8.3 Non-renewable energy
Energy provides lighting and heating in our homes and offices. It powers computers,
televisions and factory machinery. It fuels transport and has helped us develop and improve
our quality of life.
So far, non-renewable resources like coal, gas and oil have been easy to find, and seemed
quite cheap. The real cost is in the pollution they cause and the changes to the world’s climate.

8.5 Nuclear energy
People have strong views about nuclear energy. Some think it dangerous and want it
banned. Others see it as a clean and modern source of power which can meet our needs for
many years to come.
1
Q
Read what people have to say in the nuclear debate.
Nuclear power is very cost
effective. 1 tonne of
uranium ore can produce
as much electricity as
25,000 tonnes of coal.
There is always the
risk of a nuclear leak
or accident.
Safety is very important in
nuclear power stations.
Accidents are very unlikely.
Getting rid of
radioactive nuclear
waste is very difficult.
We should have nuclear
power. The world’s fossil
fuels, especially coal and
oil, will eventually run out.
Nuclear waste remains
radioactive for thousands of
years and must be buried
deep under ground.
We don’t need nuclear
power. More efficient
industry and energy-saving
homes will reduce the need
for electricity in the future.
2
Q
3
Q
Nuclear waste is minimal
and can be stored safely
under ground.
Nuclear power stations
cost a lot to build and
are expensive to run.
Nuclear power is ‘clean’. It
emits no waste gases which
pollute the atmosphere,
worsen the greenhouse effect
or produce acid rain.
Shade opposing views on the same issue, e.g. safety, in the same colour.
Why might nuclear power be a valuable energy resource in the future?

8.6 Renewable energy resources
Resources such as water, wind and the sun can be harnessed to supply us with renewable
energy. They tend to be difficult and expensive to use but cause little pollution and will
never run out.
As coal, gas and oil run out, renewable energy resources will become more important.

The drawing shows six main types of renewable energy resources. Complete the labels with
words from the Wordbox.

estuaries (mouths).

8.7 Wind power
The wind has been used for thousands of years as a power source for sailing ships and
windmills. Nowadays, huge wind turbines can generate electricity from the power of
the wind.

8.9 Energy and the environment – oil in Alaska
The exploitation of any type of energy can damage the environment. Most damage is
done by fossil fuels such as oil.
1
Q
Read the following statements about the oil industry.
Large areas of land have to be cleared when drilling for oil for laying pipelines
and building refineries and terminals.
Drilling rigs in the sea are ugly and can be a hazard to shipping.
Natural vegetation, wildlife habitats and sensitive marine reserves are destroyed.
Oil refineries are eyesores, especially if in an area with attractive scenery.
If underwater pipelines fracture, oil can be spilled.
Drilling for oil is very noisy.
Any oil spillage and discharges can kill wildlife and pollute beaches.
An explosion on a drilling rig or oil tanker could endanger life.
Smoke from serious fires causes air pollution.
Oil refineries and terminals release fumes into the air when oil is being refined.
If an oil tanker runs aground, oil escapes into the sea and is washed up onto the coast.
Oil is washed onshore, killing sea birds and affecting seal colonies.
Illegal, deliberate discharges of oil at sea cause serious pollution.
