3. Relatively Safe Transport
4. Massive Economic benefits
, 5. Useful bioproducts
6. Relatively easy to set up/maintain
Disadvantages of fossil generation - Answers 1. environmental pollutants
2. Non-renewable
3. cost for fuel to be delivered
4. mining results in large impact on environment
Megawatt - Answers equal to one million watts of electricity
Hydroelectric Generation - Answers electric power is generated by water flowing through a turbine,
which is coupled solidly to a generator
3 methods of generating power by water flowing through a turbine - Answers 1. natural water fall
2. Constructing dams
3. Pump Storage
Advantages of Hydroelectric Generation - Answers 1. Low operating cost
2. High production capability
3. a renewable resource - water
4. Does not require any fuel
Disadvantages of Hydroelectric Generation - Answers 1. Usually Located far from the load centers
2. Cost to construct
3. Land Lost to backwater
4. Impact on Wildlife
Nuclear Generation - Answers Steam not obtained from the burning fuels. Rather the heat is obtained
by nuclear fission process which takes place in the reactor
