Learning Objectives
Understand how power is produced Be able to identify the benefits and
drawbacks of various sources of power
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 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.
Hydroelectric Power
Advantages Renewable No air pollution No fuel costs
Disadvantages Flooding valleys has
serious consequences
Expensive to build initially
Wind Power
Advantages Renewable No air pollution No fuel costs
Disadvantages Dependent on the
wind Some people find
them ugly Need lots of turbines
to produce enough power
Tidal Barrage
Advantages Renewable No air pollution No fuel costs Produces lots of
power
Disadvantages Huge initial cost Environmental
concerns
Solar Power
Advantages Renewable No air pollution No fuel costs
Disadvantages Needs sunny
conditions
