Tidal Power
The use of offshore underwater turbines using the tides to generate electricity is a relatively new concept of
creating clean energy. By using the current generated by the differences in low and high tide the movement of the
propeller, similar as a wind turbine, will provide the power necessary for a turbine to generate electricity.

New - The application of the propeller-powered turbine system for underwater purposes offers an entirely new
way to create clean energy. Although tidal and wave power applications have been under development for some
time the (modular) offshore underwater turbine system offers a relatively inexpensive and efficient solution for
clean energy generation.

Replace - With the end of the fossil fuels nearing the search for (clean) alternatives continues. Although the
above visualised system can only be used in areas with large differences in height between high and low tide
(twenty locations worldwide, often deep bays) it can contribute to the replacement of current energy generating

Change - The use of water or the tides to generate electricity is more reliable then the sun and wind, because
water movement (especially the tides) is continuous, while the presence of the sun and wind are not. Using these
offshore underwater turbines can renew the attention for hydroelectric applications.

Growth - Only twenty locations worldwide have been appointed to be able to use the current system. This has
directly to do with the necessary difference in height between the high and low tide (several dozens of
centimetres). Currently the application of the system is considered in Argentina, Australia, Canada, India, Korea,
Mexico, the UK, the USA, and Russia. Once the system gets improved it might be applicable in more locations.

Other - The system is not yet sophisticated enough to offer a real attractive cost-revenue ratio. Furthermore
additional research needs to be done on the reliability of the hardware and its influence on the environment and
