The rotation of the planets slows through the use of tidal power.
No, and there are no proposals for tidal power in Australia. For more information on the status of tidal power in Australia, see the related link.
Depends. It certainly can do; an example of a tidal power project potentially destructive to the marine environment is the proposed Severn Barrage, which basically dams the Severn estuary between England and Wales. There are also completely non-invasive ways of producing tidal power, such as the the 'snakes' which float on the water off the coast of Portugal (see link). As yet these more advanced methods are less effective though.
Utility companies that use tidal energy would also use other ways of generating power, because tidal energy can only be collected when tides come in or out, that is, usually four times a day. Most utility companies would have access to the national grid and feed their tidal power into it. They would be able to draw on power from other sources when the tide was quiet.
Tidal power produces electricity, the same electricity that you use in everyday life. Some countries are planning systems that will use the tides as a source of renewable energy. That is an extremely good idea.
Hydroelectric power (dams)Tidal powerWave power
Tidal power is caused by the moon (largely). Tidal power has no effect on the moon.Yes, tidal power, if it is harnessed properly by wave motion machines, dams and barrages, has enough power to generate all the Earth's electricity needs. However, this power is difficult to capture. Dams and river barrages are large and cause some damage to the environment and obstruction to river travel.Various experiments are underway trying to find suitable ways of harnessing the power of tides and ocean waves. No one has discovered a cheap and easy way to do it yet.
Sunlight is renewable. With solar panels you can use it to produce electricity.Wind power is similar.Water power (hydro-electric dams, tidal power, wave power) is similar.Boiling water from under the ground is renewable, too.
Hydroelectric power
We don't use tidal power in Maine because we don't have any tidal barrages in Maine.

It depends on the type of power station. Some, such as dams just use the weight of the water coming out. Tidal powerstations use the force of the tides, kind of like how windmills use wind. I, however, do not believe that there are currently any sources of hydroelectric power that use waves.
There are two kinds of tidal power stations: * Tidal stream systems, which use turbines turned by the moving water to generate electricity. Very like wind power. * Barrage systems. These are like dams built across rivers. After the tide comes in, the gates are closed. When the tide is low enough on the downstream side, the water flows through turbines rather like a hydro-electric dam.
There are models that are made to test different situations. Dams, wave motion and tidal motion are all forms of hydro electricity.
Singapore does not use hydroelectric dams to generate electricity.
