The term "alternative energy" refers to sustainable means of generating electrical power that do not involve burning fossil fuels. Potential sources of energy in the ocean include solar, wind, waves, tides and geothermal energy.

In recent years, there has been a surge of interest in the development of these industries. Numerous projects have been proposed – and in some cases implemented - throughout the U.S. and world, encompassing a broad range of designs and locations.

The Surfrider Foundation recognizes that technologies that utilize ocean waves, tides, currents and wind may offer important benefits as renewable sources of energy that will reduce emissions of greenhouse gases. These alternative energy sources may also provide economic development through a cutting-edge industry for coastal communities.

Surfrider also recognizes that there are many questions and concerns about ocean energy, including potential impacts to ocean recreation, nearshore ecology, coastal processes, public safety, aesthetics, and fishing access.

The Surfrider Foundation has developed a Policy on Alternative Ocean Energy that articulates as set of ‘best practices’ for evaluating or planning for potential projects.
