A new federal study says Hawaii’s waves stand to provide a massive source of alternative energy.

The U.S. Department of Energy says 80 terawatt hours of electricity could be generated annually off the island coast.

By comparison, utilities generated only 10 terawatt hours from all sources for the counties of Honolulu, Maui and Hawaii Island in 2010. Tapping into the clean energy is the challenge.

The U.S. Department of Energy released two reports last week detailing the country's ocean wave and tidal resource energy potential. Mapping and Assessment of the United States Ocean Wave Energy Resource report is a follow-up to the Electric Power Research Institute's 2004 study, with the most recent evidence suggesting a 26 percent increase in wave energy resources.

The Assessment of Energy Production Potential from Tidal Streams in the United States, led by researchers at Georgia Tech Research Corporation in collaboration with DOE, is the first of its kind in the U.S. and includes a geographic information systems (GIS) tool available for public use. The report data concludes that U.S. water power resources, including ocean wave, tidal and conventional hydropower, have the potential to provide 15 percent of our nation's electricity by 2030.

The notion of harnessing energy from the sea has captured the human imagination for years. With interest in renewable energy at an all-time high, steps are being taken to turn this idea into a reality.

As the global need for renewable energy sources continues to surge, one innovative company has released technology that could have a major impact on utility and energy companies, as well as their customers, well into the future. The Pelamis Wave Energy Converter, made by Scottish company Pelamis Wave Power, is the first commercial machine that can generate electricity from offshore wave energy. Since the company first tested its prototype wave energy converter between 2004 and 2007 in Scotland, four additional Pelamis machines and two designs – the P1 and the second-generation P2 – have been created.
