Advantages:
Does not depend on costs of uranium, oil, or other fuels.Pollution is rarely created.It doesn't require as many employeesIt can be set up in many sizes.Stations can operate and run for long periods of time.Reduces greenhouse emissions.Relatively low maintenance costsCan be used throughout the world.
Advantages
It is transportable over long distancesIt is silentIt can be used produce magnetic fields, which can be used to propel motorsIt is very transformableIt is very fast, virtually the speed of lightIt can be used to produce other forms of radiant energy, such as radio waves, microwaves, radiant heat and lightEDIT: You can store it for use later
It is the Esperanto of energy, it can covert to just about anything
Disadvantages
It can kill youWe become dependent on itWe use other dirtier forms of energy (nuclear, fossil fuels) to produce itThere is growing concern that the magnetic fields around transmission lines may be unhealthy

The water can be saved for use another time when electricity demand is high. The build up of water in the lake means that energy can be stored until needed, when the water is released to produce electricity.Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades.The lake that forms behind the dam can be used for water sports and leisure / pleasure activities. Often large dams become tourist attractions in their own right.The lake's water can be used for irrigation purposes.When in use, electricity produced by dam systems do not produce green house gases. They do not pollute the atmosphere.Hydropower is a fueled by water, so it's a clean fuel source. Hydropower doesn't pollute the air like power plants that burn fossil fuels, such as coal, oil or natural gas.Hydropower is a domestic source of energy, produced locally near where it is needed.Hydropower relies on the water cycle, which is driven by the sun, thus it's a renewable power source so long as the rain keeps falling on the dam catchment area.
