Harvesting the Power of the Ocean But another significant, untapped renewable energy source also exists: the world's oceans. It is estimated that harnessing just 2 one-thousandths of the oceans' untapped energy could provide power equal to current worldwide demand. Engineers have attempted, with varying success, to tap ocean energy as it occurs in waves, tides, marine currents, thermal gradients, and differences in salinity.

8 Benefits You Didnât Know About Ocean Wave Energy Wave energy contains roughly 1000 times the kinetic energy of wind. Hence, it allows smaller and less conspicuous devices to produce power. Also, water being 850 times as dense as air results in much higher power produced from waves averaged over time.

Ocean zones They are sometimes referred to as ocean layers or environmental zones. The ocean environment is divided into two broad categories, known as realms: the benthic realm (consisting of the seafloor) and the pelagic realm (consisting of the ocean waters).elow this layer, down to the deepest parts of the ocean, it is perpetual night. This last layer is called the aphotic zone (meaning without light). At one time, scientists thought that very little life existed within the aphotic zone.

Ocean Current Energy Ocean currents are relatively constant and flow in one direction, in contrast to tidal currents along the shore. While ocean currents move slowly relative to typical wind speeds, they carry a great deal of energy because of the density of water. Water is more than 800 times denser than air. So for the same surface area, water moving 12 miles per hour exerts the same amount of force as a constant 110 mph wind. Because of this physical property, ocean currents contain an enormous amount of energy that can be captured and converted to a usable form.

Huge 'Ocean' Discovered Inside Earth Scientists probing the Earth's interior have found a large reservoir of water equal to the volume of the Arctic Ocean beneath eastern Asia. The left figure is a slice through the Earth, taken from the figure on the right, showing the attenuation anomalies within the mantle at a depth of roughly 620 miles.

Ocean Energy A difference of at least 38 degrees Fahrenheit is needed between the warmer surface water and the colder deep ocean water. The cold ocean water can also be used to cooling buildings, and desalinated water is often a by-product. Using this type of energy source is called Ocean Thermal Energy Conversion or OTEC. It was demonstrated in Hawaii at the Open Cycle Ocean Thermal Energy Conversion (OC-OTEC) system located at the Natural Energy Laboratory of Hawaii Authority (NELHA) at Keahole Point on the Big Island of Hawaii.

Ocean Energy Tidal power requires large tidal differences which, in the U.S., occur only in Maine and Alaska. Ocean thermal energy conversion is limited to tropical regions, such as Hawaii, and to a portion of the Atlantic coast. Wave energy has a more general application, with potential along the California coast.enerating technologies for deriving electrical power from the ocean include tidal power, wave power, ocean thermal energy conversion, ocean currents, ocean winds and salinity gradients. Of these, the three most well-developed technologies are tidal power, wave power and ocean thermal energy conversion.

Why Earth is a closed thermodynamic system that must obey the 2nd Law of Thermodynamics Open Systems. The ocean is an open system. The ocean is an example of an open system. The ocean is a component of the hydrosphere and the ocean surface represents the interface between the hydrosphere and the atmosphere that lies above. Solar radiation passes through the atmosphere and is absorbed by the ocean.

Environmental Impact of Wave Energy Because wave energy generation occurs on the oceans surface either shoreline, near-shore, or located far out at sea, the possible environmental effects of wave energy generation are similar in many ways to those of offshore wind power generation.

LiftBoat Lifting Expectations? â Ezion, Ezra, Swissco & Triyards Below is an energy landscape of oil and gas countries in SEA. Indonesia, Malaysia and Brunei lead the oil and gas production in SEA while potential growth lies in countries such as Vietnam and Myanmar. Over the years, SEA had a growing thirst of energy due to sustained economical and social development.he decline in energy production in SEA aside from rising consumption is a result of large numbers of maturing fields, particular the ones in shallow waters. Many oil platforms are already old and required maintenance/upgrade such as replacement of tubings, valves, pumps that may be malfunctioned.

How Ocean Power Works Environmental Benefits of Ocean Power. Oceans cover more than 70 percent of Earth's surface, so clearly they represent an enormous energy resource. For many years, power companies have interested themselves primarily in the nonrenewable energy sources -- oil and natural gas -- trapped beneath seafloor sediments. But recently, as prices of fossil fuels continue to climb, the ocean's renewable energy sources have become more attractive. In the near term, power generation based on waves, tides and currents will likely contribute only a small sliver of the energy pie.

Climate Change: Ocean Heat Content July 14, 2015. The ocean is the largest solar energy collector on Earth. Not only does water cover more than 70 percent of our planet’s surface, it can also absorb large amounts of heat without a large increase in temperature. This tremendous ability to store and release heat over long periods of time gives the ocean a central role in stabilizing Earth’s climate system.
