Fossil Fuels.
(Links in pink will take you to the GCSE Chemistry site).
Most of the electricity generated
in the world today
comes from power stations which burn
fossil
fuels.
Fossil fuels are coal, oil and
natural gas.
The original
source of the energy is the
Sun.
Plants use sunlight energy for
photosynthesis.
Coal is made from plant remains.
Oil and natural
gas are made from both plant
and animal
remains,
which in turn received their energy
from eating plants.
Advantages of fossil fuels.
1. They give a large amount of energy from a small amount of fuel.
2. They are readily available.
If you need more energy, you just burn more
fuel.
3. They are relatively cheap.
Disadvantages.
1. They are non-renewable.
Once you burn them, they are
gone.
2. They cause pollution.
Burning a fossil
fuel can produce carbon dioxide, sulphur dioxide and smoke.
Carbon dioxide is a greenhouse gas and
causes global
warming.
Sulfur dioxide causes acid rain.
3. They use water as a coolant
and may return warm water into a river.
This decreases the amount of dissolved oxygen in the
river.
