nuclear electric power generation

hydroelectric power generation

advantages

1.     Nuclear fuel is of high density of energy, so the fuels in nuclear power station are all of small size. It is easy to store and transport.

2.     No greenhouse gases, so no air pollution as thermal power station.

3.     The fuel is comparatively cheap and the resources of fuel are stable without the influence of international economic situation.

4.     The fuel is renewable.

1.     It is green and does not consume the primary energy.

2.     It efficiency of generation can be as high as 90%.

3.     It can start generation efficiently, in minutes.

4.     The fuel is renewable.

disadvantages

1.     The waste of nuclear power station is harmful to human being for its radiation. It needs costly and serious measures to deal with.

2.     The nuclear power station will give out more heat in the generation, so it causes severe thermal pollution.

3.     The cost of investment is high. The power company will run in a high financial risk.

4.     The construction of nuclear power station can easily cause political dispute.

1.     Its establishment depends a lot on the geographic environment, so the generation capacity is limited with the maximum of 300MW per unit.

2.     The cost of construction is high and time consuming.

3.     It relies on the nature a lot and the seasonal alternation of water level, the other natural disasters may all possibly affect its operation.

4.     The cost of transmission is high if the dam site is far from the load center.
