Think about it, the ocean is moving 24/7/365. Between the waves and the tides, there is a constant source of renewable energy being generated, but not being harvested. “Generating technologies for deriving electrical power from the ocean include tidal power, wave power, ocean thermal energy conversion (OTEC), 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. 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. The western coastline has the highest wave potential in the U.S.; in California, the greatest potential is along the northern coast.
California has more than 1,200 kilometers (745 miles) of coastline, and the combined average annual deep water wave power flux is over 37,000 megawatts (MW) of which an upper limit of about 20 percent could be converted into electricity. This is sufficient for about 23 percent of California’s current electricity consumption. However, economics, environmental impacts, land-use and grid interconnection constraints will likely impose further limits to how much of the resource can be extracted.
Although technology is still at a relatively immature pilot project stage, economic projections indicate that ocean energy could become cost-competitive over the long-term.”
Diane Tegarden’s wildest release “Anti-Vigilante and The Rips in Time” is a science fiction novel set in the distant future with its hooks deep into renewable energy, which changes the face of the planet.
“Terrax, the Crystal Planet, is an exacting world. A place where human physical contact is impossible and stepping outside is virtual suicide. The atmosphere is a hurricane of Coriolis winds and deadly scattershowers, composed of toxic metals formed into whip-like threads kilometers long. Immense Ocean Domes cover over the toxic sludge where the oceans used to be, and the surface of Terrax is covered in crystalline structures, called the Hives, where only the upper crust lives. No one can survive the raw elements; all must reside inside buildings, vicariously living through virtual reality programming.”

Did you ever think about where islands get their electricity?
If they have to use gas or oil to run engines that create electricity, it’s costly, inefficient and pollutes the air. Other resources are solar power, tidal turbines off the coast, or WEC (wave energy conversion).
The June 25th edition of Renewable Energy Magazine just ran in interesting article on Indonesia’s move to use wave energy conversion.
“The Indonesian archipelago is facing extensive challenges with its complex power network and the deployment of Bombora Wave Power’s WEC would greatly improve access to electrical power for Indonesian citizens. The country’s present wave energy resource level is somewhat less than that currently available to other countries and the WEC is very attractive to the Indonesian market, on account of its ability to collect wave energy from a wide wave front.
The WEC’s flexible membrane and simple valving, squeezes air through a closed circuit and extracts energy with an air turbine to generate electricity.”
