ocean currents as alternative energy

Ocean currents are also gaining significance as a possible form of alternative energy. Because water is dense, it carries an enormous amount of energy that could possible be captured and converted into a usable form through the use of water turbines. Currently this is an experimental technology being tested by the U.S., Japan, china, and some of the European Union countries.

Whether ocean currents are used as alternative energy, to reduce shipping costs, or in their nature to state to move species and weather worldwide, they are significant to geographers, meteorologists, and other scientists because they have a tremendous impact on the globe and earth-atmosphere relations.

I learnt that it reduce shipping cost by changing the ocean current and that the currently this is an experimental technology being tested.

With ocean current is all pulls some where normally towards the land.

I wonder how people use water in turbines.

Ocean Currents

What is an ocean current?

Ocean currents are vertical and horizontal movement of the two surface and the deep water throughout the worlds oceans. Currents normally move in specified directions.

Oceanic currents are found all over the world in many sizes.
Some of the prominent currents are found in California and Humboldt currents of the pacific, the gulf stream and the Labrador Current in the Atlantic.

Surface currents are those found in the upper 400 meters or 1,300 feet of the ocean and that make up about 10% of the entire worlds ocean.
