According to a new study by the Carbon Trust up to 240 GW of capacity of marine energy could be installed worldwide by 2050. Out of these, 75 percent could be coming from wave, and the remainder by tidal energy.

The total market for both wave and tidal energies (more…)

PG&E, Pacific Gas and Electric, provides electricity and natural gas to roughly 40 percent of all Californians. Because this equates to approximately one out of 20 Americans, PG&E recognizes the products that are produced and delivered to serve customers has an impact on the environment. Because of this, (more…)

The ARPA-E Energy Innovation Summit took place last week just outside Washington, D.C., and the show floor was filled with projects that promise to advance the United States as a force in clean energy. Most of the exhibiting companies were very young and in possession of early-stage technologies that are difficult to (more…)

As a country with enormous potential for both wind power and solar energy, India has been steadily working towards building up the respective technologies to establish their renewable energy reputation. One of the areas they have yet to consider, however, is tidal and wave based energies and India is about to make a change for the better in that department. With plans to (more…)

Wave energy technology is one of the more fascinating renewable energy technologies that are being researched today. In concept, they bear a similarity to how wind power works by harnessing a naturally occurring movement and transfer of energy in order to generate electricity. Sadly, a great deal of wave energy projects so far have had varying degrees of success or (more…)

A U.S. startup is working on a plan to install hundreds of 40-kilowatt hydrokinetic turbines, each the size of a large jet engine, along the bottom of the Mississippi River, an ambitious renewable energy project developers say could someday produce more than one gigawatt of (more…)

As renewable energy moves steadily into the future, the possibilities that exist thanks to tidal and wave energy are becoming more and more widely accepted by countries hoping to adopt such technologies. While tidal and wave based projects are found around the (more…)

The news that the world’s largest tidal turbine – 1 MW in size – will be installed off the coast of Scotland near Orkney should come as no surprise.

Primitive tidal mills operated in the England date back to the 11th century. During the 18th century, several tidal mills popped up in Western Europe. The first modern tidal plants borrowed from conventional (more…)

An Irish university has launched the world’s largest hydro-electric wave energy converter off the coast of northern Scotland.

The so-called Oyster is a mechanically-hinged flap that is embedded into the sea floor — at a depth of about 32 feet (10 meters) — and moves with the motions of the waves. That wave energy pumps high-pressure water to a shore-based electric turbine.

Power will be fed into the national grid and provide electricity to homes in the Orkney islands. Researchers say a farm of 20 Oysters could eventually provide enough electricity to power 9,000 three-bedroom homes.
