Marine

 

Wave and tidal power pilot plants have been very costly to build per kW and in the case of wave power have often suffered very high ongoing maintenance costs. This makes the average carbon footprint of current marine (tidal and wave) power nearly 100 times larger than that of wind, with very much higher delivered energy costs.
