California is looking at harnessing power from the sea to help meet the state's energy demand. Although not yet widely used, many believe tidal power has more potential than wind or solar power for meeting alternative energy needs. Quest radio looks at plans for tidal and wave power off San Francisco and along the northern California coast.
You may listen to the "Harnessing Power from the Sea" Radio report online, as well as find additional links and resources.
