Pollution
Pros and cons of tidal power
Constant, efficient
Can kill marine wildlife, costly
Pros and cons of geothermal
Reliable, high efficiency
Location specific, high investment costs
Pros and cons of hydroelectric
Safe, clean fuel source

3 fossil fuels
Coal
Oil
Gas
Advantages of fossil fuels
Cheap
Provide jobs
Disadvantages of fossil fuels
Produce CO2, limited and will run out
Coal and oil produce sulfur dioxide which causes acid rain, oil spills
How do fossil fuels work?
1) heat from burning fuel
2) heats water to steam
3) steam turns a turbine
4) turns a generator which creates electricity
Advantages of nuclear power
High and reliable output, can match demand
Disadvantages of nuclear power
Very polluting, running out, involves mining
