Tomorrow's Energy

Pros and Cons

You are going to find out what the advantages and disadvantages are for the different types of energy. It is unlikely that a single source of energy will ever be used to supply all our needs. A mix of sources will be used as it is today. Much energy is used to meet two types of demand:

• Baseload is the level of electricity at must be supplied constantly to meet regular demand
• Peak time is the extra amount that must be supplied to meet short-lasting increases in demand. Think of the amount of electricity required when everyone puts the kettle on at half-time when they’re watching the world cup football final!

So the energy supply must be:

• Reliable
• Safe and secure
• Low in cost
• Environmentally friendly
  

In groups, choose one of the following reports on each type of energy supply. Decide what are the advantages and disadvantages. Be prepared to answer questions from the rest of your class.
