Power Stations

Biomass - Wood Burning.

(Links in pink will take you to the GCSE Chemistry site).

A wood burning power station is similar to one which burns fossil fuel.

The original source of the energy is the Sun.
Growing trees use sunlight energy for photosynthesis.


Advantages
of
wood burning.

1.  It is renewable.
Trees can be grown at the same rate as they are burnt.

2.  It is reliable.

3.  Although burning wood produces carbon dioxide,
it does not contribute to global warming.
This is because the growing trees take in carbon dioxide for photosynthesis
at the same rate that the power station emits carbon dioxide during burning.


Disadvantages.

1.  Wood burning produces sulfur dioxide which causes acid rain.

2.  A large area is needed to grow enough trees
to keep the power station running.
The land could be used for other purposes, for example growing food.
