Tidal power needs a suitable bay or river mouth that fills up with massive amounts of water at high tide, but that only has a small exit to the sea, otherwise it is not economical. There are not many suitable locations in the US for tidal power.
Tidal energy is a form of gathering energy from the tidal currents. Depending of the size of the system it could cost billions. A system planned for Britain would cost 15 billion pounds to build.
Tidal power is useful because it generates electricity that is renewable, free and non-polluting. So it is an excellent replacement for energy from fossil fuels (coal, oil and natural gas) which is non-renewable, expensive and polluting (that is, causing global warming).
it is caused by the shocks of an earthquake and the earthquake is caused by the movements of the plates at the bottom of the earth
The amount of Watts a tidal energy gives is 200-300W
more than wave also more preditable than saolar AND wind!
Every turbine gives 300-400 homes power.
Sihwa Lake Tidal Power in South Korea generates 250 MW of electricity, and has been in operation since last year. Korea has plans to begin construction of a 1 GW tidal power plant in 2017. Since a watt is equal to one joule per second, a gigawatt is 3.16x10^16 joules per year. Theoretically, much larger tidal generation facilities could be built, but there are practical economic and environmental considerations to factor in that.
It's difficult to say. A tidal wave, or a tsunami, has an amazing amount of power, but it is all over in a hour or two. Tidal mills can capture the tidal water twice a day and use it to generate clean electricity. This will continue for ever (or until the turbines need to be replaced).
Because their isn't much water in the desert.

Energy takes up no space, at all.
Realistically none of the worlds energy needs are done in this manner.
