Creating Electricity
Fossil Fuels
Coal
Oil
Gas
Advantages
Fossil-fuel powers are very reliable
Large amounts of energy can be generated cheaply
Disadvantages
Non renewable - will run out
Produces harmful gasses like Carbon Dioxide and Sulfur Dioxide
Nuclear Energy
Advantages
Does not produce harmful gasses
Very reliable
Produces a lot of energy - High yield
Disadvantages
Expensive to build
Expensive to decommision
Produces radioactive waste that must be stored safely for a long time
High risk from nuclear accidents
Wind energy
Advantages
Renewable - will not run out
Does not produce harmful gasses
Disadvantages
Will only operate when it is windy
Low yield
Can be unsightly - may spoil the view
Hyrdoelectric
Advantages
Renewable
No harmful gasses
Very large amount of energy produced instantly and reliably
Disadvantages
Large dams can be expensive to build
habitats are destroyed when the valleys are flooded
Wave and Tidal
Advantages
Renewable
Very predictable
High yield
Disadvantages
Can destroy habitats and wildlife populations
Expensive to build
Solar power
Advantages
Disadvantages
Does not generate electricity at night
Uses up a lot of land in large scale power stations
Lots of solar panels needed to produce a significant amount of energy
Renewable
Predictable - Available in the daytime
Cheap to install and readily available to the public
