Term
How does a Nuclear Reactor work?
Definition

1. The fossil fuel is burnt to convert its stored chemical energy into heat (thermal) energy.

2. The heat energy is used to heat water to produce steam.

3. The steam turns a turbine converting heat energy into kinetic energy.

4. The turbine is conected to a generator which transfers kinetic energy into electrical energy.

Term
Name the advantages of Wind Power.
Definition
No pollution (except when they are manufactured), No fuel costs, Minimal running costs, No permanent damage to the landscape.
Term
Name the disadvantages of Wind Power.
Definition
Spoil the view, Very noisy, Unreliable, Impossible to increase supply if there is extra demand, Initial costs are very high.
Term
Name the advantages of Solar Power.
Definition
No pollution, Reliable source of energy (In sunny countries), No fuel costs, Minimal running costs.
Term
Name the disadvantages of Solar Power.
Definition
Unreliable (in not sunny countries), Initial costs are high, Not practical for the national grid.
Term
Name the advantages of Hydroelectric Power.
Definition
Can provide an imediate response to an increase in demand for electricity, Reliable, No fuel costs, Minimal running costs.
Term
Name the disadvantages of Hydroelectric Power.
Definition
Requires the flooding of a valley (by building a big dam), Loss of habitat, Damage of the landscape, Initial costs are very high.
Term
Name the advantages of Wave Power.
Definition
No fuel costs, Minimal running costs.
Term
Name the disadvantages of Wave Power.
Definition
Lots of wave-powered turbines are needed around the coast, No pollution (except when they are manufactured).

Definition
No pollution, Reliable, No fuel costs, Minimal running costs.
Term
Name the disadvantages of Tidal Power.
Definition
Prevents free access by boats, Spoils the view, Alters habitats, Initial costs are moderately high.
Term
Name the advantages of Geothermal Power.
Definition
No pollution.
Term
Name the disadvantages of Geothermal Power.
Definition
Not many suitable locations (only possible in volcanic areas where hot rocks lie close to the surface).
