Renewable power debates often include the discussion of ocean currents and tidal power. Tidal power is very similar to solar and wind power, in that it utilizes nature in a way that’s not damaging to its source (in this case the ocean).

It is often hailed as a possible new form of electricity. However, there are still a few problems scientists are working out regarding the use of ocean currents for tidal power.

The main concern regarding the use of ocean currents for tidal power is the possible damage not done by using the powerful source of the ocean itself. Instead, the concern comes with the harnessing of the power.

To harness the power, there would be a need for turbines located in the ocean. These large machines would present a real risk to marine life or possibly swimmers. Environmentalists are not excited about the thought of putting dangerous machinery into the ocean.

The coverage by animal rights groups of the possibilities of danger associated with tidal power is making quite an impact. While ocean current power was once hailed as a positive possibility, these groups are clear to state the dangers involved with turbine machinery are far worse than first expected.

Still not giving up on tidal power, scientists are further studying ocean currents and are trying to create a safer way to harness tidal power for years to come. If they are successful, it could be possible to say ocean currents could indeed power the world.
