"Thermal energy from the suns heat and mechanical energy are the two types that the ocean can produce. Over half of our earth is covered by oceans, which makes them the worlds largest solar collectors. The heat from the sun warms the surface water a lot more than the deep ocean water, and the difference in this creates thermal energy. It is said that just a small portion of the heat trapped in the ocean could power the world"(http://www.renewableenergyworld.com/).
It is pretty cool that the ocean produces energy just like the sun, and the wind. We seem to lean more on other sources, like oil, nuclear power and so on. I think that the natural elements of the world that produce energy, like the sun, the ocean, and the wind should be used more because they don't pose a threat to us, our world, and our way of life. They do not seem to produce the energy as fast as us humans need it. "The thermal energy that the ocean produces is used for many reasons, including electricity generation" (http://www.renewableenergyworld.com/). To me it sounds like the ocean is a powerhouse of energy that is still untapped. The sun, the ocean, and the wind together create massive amounts of energy, yet it seems like people do not have the time to wait around for them to produce energy. What will us humans do when we run out of oil and natural gas? What will we humans do when our ozone layer is gone from all of the pollution we have forced upon it? There is nothing we can do! We will be slowly on our way to the grave, because we have one foot in it already.
