Department of Energy Findings on Wave and Tidal Energy
The United States Department of Energy just released a study that has been conducted on the possibilities of Wave and Tidal energy for the United States annual electricity production. Subsea World News has reported that: The new wave and tidal resource assessments, combined with ongoing analyses of the technologies and other resource assessments, show that water power, including conventional hydropower and wave, tidal, and other water power resources, can potentially provide 15% of our nation’s electricity by 2030. These numbers are not based completely in reality, they are a theoretical estimate of the amount of energy that could potentially be produced by harnessing the natural movements of the waves and tides in the world’s oceans. One way to possibly harness the energy created by the constant movement of water as the moon rotates around the earth is to put windmill-like devices in channels where tides are strong, such as in the Molokai channel. In their article Subsea World News states “The West Coast, including Alaska and Hawaii, has especially high potential for wave energy development”. The Department of energy’s Water Power Program is supporting the development of technology that can tap into these vast power sources, and the Water Power Program is undertaking a detailed assessment of water power technologies so that it can more accurately predict the cost of development and implementation of these new technologies. There are currently 40 projects which are being sponsored by the Water Power Program which will serve as a basis for performance evaluation, and possibilities of cost reduction. With the development and implementation of these new technologies the U.S. stands to make a huge step towards reducing its dependence on foreign oil, and other energy sources. With seasonal waves and constantly changing tides Hawaii could stand to gain a lot from this new technology, from reduced energy costs, less dependence on outside sources, and the creation of jobs.
