Marine and Hydrokinetic Power



Hydrokinetic technologies have come to the forefront of renewable energy in recent years as the power of waves are a relatively untapped source. Water is a staggering 832 times denser than air and makes the potential power of hydrokinetic energy an opportunity that we cannot ignore for the future of our environment.

Hydrokinetic power uses the kinetic power of waves, tides and currents to create electricity. The development of technologies used in harnessing this power is still being worked on however pilot schemes are being put into place to further the development. It is difficult to get to a point where full use of the technologies is conceivable however with increasing funding going towards renewables the possibilities are growing daily with this relatively new technology.

The most simple and powerful way of harnessing marine hydrokinetic power is by using both near and off-shore waves. By extracting only 15% of the potential kinetic power from waves in the USA it would exceed the amount of electricity currently generated by hydroelectric dams. This is an immense possibility considering there amount of water that covers the entire planet.

Not only are the kinetic powers of waves harnessable but experts believe there is a lot of promise held in ocean tides. As the tides change they produce a phenomenon known as a tidal stream which is a powerful current. Not only is this current powerful enough to produce high amounts of energy but it is highly predictable which means it is easier to predict the surges in electricity and when support would be needed.

While the effects of hydrokinetic technologies on climate change are easy to define as there are no dangerous greenhouse emissions further research is necessary to see the wider implications of using this technology. Many renewable resources have been able to work in means of protecting the environment from harm. Before it is possible to give the green light to use new and untested technology there needs to be assurances that there wont be any kinds of danger to marine biodiversity.


It is also exceedingly expensive getting new renewable energies into use as there are so many complications along the line. Without the funding from governments and dedication from researchers and scientists there is no knowing how long it could take to get to a stage where we are able to use hydrokinetic technologies to harness electricity. Fortunately it is becoming a more pressing matter not only in the eyes of those working on the technology but also on a wider scale. The general public is becoming much more softened to the idea of using renewable energy and are much more conscious of the impact of electricity on the environment. Image can make or break a company and the time is certainly coming that there will be a shift in power towards renewables and a cleaner power sector which marine hydrokinetic energy is certainly a part of.
