Schalk, 90 percent of heat attributable to climate change has been accumulating in the oceans. It is causing thermal expansion and the erosion of the icecaps.
A portion of the 330 TWh a NASA study suggests has been accumulating there, can be converted to work by the process of ocean thermal energy conversion (OTEC).
Ray Schmitt, Woods Hole Oceanographic Institution, suggests OTEC's potential is 15-24 TW; whereas the world currently operates on a bout 16 TW.
Gerard Nihous, suggests as much as 25 TW is available here.
The more energy produced by this method, the more the ocean's surface would be cooled, which in turn lessens the threat from tropical storms and reduces the movement of heat towards the poles.
The oceans are the largest heat repository on the planet at the same time as they are the largest heat sink. Virtually all other forms of energy production and all energy use adds to the problem of ocean heat.
OTEC is the only form of production that ameliorates the problem.
The more energy produced, the more the ocean is cooled.
It is a renewable with a bright and virtually limitless horizon.
