Oceans cover more than 70 percent of Earth's surface, so clearly they represent an enormous energy resource. In these past 10 years or so companies have been interested in the nonrenewable resources such as natural gasses, coal, and oil. Fortunately for our world, ocean power has become more attractive. now in the near term that will only contribute to the world by maybe a little sliver, but in the long term that could definitely turn into a sizable wedge.

Part of the reason everyone likes ocean power now is because it is a never ending resource. We can be reasonably assured that it will remain in motion far into the future.Not only that, ocean power is, for the most part, predictable. the tide charts in 2010 show the high and low tides as much as every minute, while maps show both the dimensions and speed of Earth's major currents.

Another key concept of ocean power is its density. The air's density is about 1.25 kilograms every cubic meter, and the density of seawater is about three times that much, which means it can transmit more energy to turbines placed in the ocean. Currents running no faster than 5 miles per hour can turn a tidal turbine more than 30 rotations in a minute, which delivers a better output than a wind turbine of larger size operating in strong winds.

In the end ocean power is much better that all the other nonrenewable fossil fuels. there are many reasons why, one is because they are killing the earth and it is also killing the o-zone layer and that will give us a higher percentage of getting skin cancer. The other reason is because it is strong and it can help out a ton of different things better than the fossil fuels could.
