Hawaii: an Epicenter for Renewable Energy

Hawaii: an Epicenter for Renewable Energy

If that wasn’t enough, Hawaii is surrounded by yet-underexploited ocean resources . The linear power densities of ocean waves can reach monstrous quantities during a storm, and while it’s impossible to extract 100 percent of this energy from a wave, lots of research and development is underway to improve this efficiency. Hawaii has been the site of many major U.S. Ocean thermal energy conversion (OTEC) experiments , all of which contribute to the authority of this technology. In a nutshell, OTEC uses oceanic temperature gradients to circulate energy that can used to produce electricity. Warm liquid is piped from the ocean’s surface to vaporize a liquid that can drive a turbine. This gas is then cooled using water from deep beneath the ocean to restart the cycle. In 2006, Ocean Engineering & Energy Systems announced their plants to construct two of the world’s largest OTEC ...
