Moon Power?

Harvesting tidal power is overall a very effective and economical form of power, it uses the tide (waves) to spin turbines and create electricity. It relies on sea water to create electricity making it a renewable form of power; there's enough sea water and soon there will be far too much of it. However it requires a beach to run so not affective in all locations, but very good for Australia and in particular Melbourne. Tidal power is my favorite form of power as i am a very Melbourne based person and i know that most of Melbourne's beaches are all but useless.
Solar power is whilst very expensive, a good way to harvest electricity especially considering that the suns rays are just going to keep getting hotter and hotter. Solar power takes the heat provided by the sun and uses that energy to form electricity by charging turbines (above).Wind power harvests the kinetic energy from the wind and uses it to turn an areal turbine (see above) in order to make electricity. This is a very good form of electricity as we are so rich in wind. Offshore wind turbines are ideal for some ares because they are not visible from land so that neighbors don't complain about the "eyesores" being near them as much.

Renewable forms of power are sustainable because they don't require any finite fuel sources such as coal or natural gas. All though these forms of electricity require large amounts of copper in order to create and spin turbines which isn't as sustainable.
