Task

Stick the diagram in your book Label it Underneath explain how this power plant

generates electricity

Fossil Fuel Power Plants Where does the

energy come from?

What gases are produced?

What problems do these cause?

Draw a diagram of a coal power plant showing the gases produced

Fossil Fuel Power Plants

Advantages High power output

Disadvantages Non renewable Lots of heat wasted Slow to start up Fuel supplies will run

out Causes global

warming and acid rain

Nuclear Power

The energy source for nuclear power is uranium

Nuclear Power Plants

Advantages Very High power output

from small amount of fuel No air pollution

Disadvantages Waste material is

radioactive. Decommissioning is

expensive. Waste takes along time to

become safe. Possibility of terrorist

attacks.
