Tidal power is a very intriguing form of alternative energy. Our oceans could generate a large amount of power for us, if we put the right systems in place. The most commonly known system for harnessing tidal power is the tidal barrage. It is very expensive and large, but supplies equally large amounts of power. However, tidal barrages aren’t the only way to make use of the ocean’s ability to generate power.

Offshore turbines are much cheaper method of generating power by making use of the tides. They look very similar to wind farms except that they are located underwater. They work similarly too, only the turbines are moved by water currents rather than wind. The turbines are connected to a generator and electricity is produced.

Tidal power is certainly an alternative power source to consider. Advances like offshore turbines make it a more realistic option to put in place in the near future.
