'''Tidal Power'''<br>
The use of offshore underwater turbines using the tides to generate electricity is a relatively new concept of<br>creating clean energy. By using the current generated by the differences in low and high tide the movement of the<br>propeller, similar as a wind turbine, will provide the power necessary for a turbine to generate electricity.<br><br>
 
'''New''' - The application of the propeller-powered turbine system for underwater purposes offers an entirely new<br>way to create clean energy. Although tidal and wave power applications have been under development for some<br>time the (modular) offshore underwater turbine system offers a relatively inexpensive and efficient solution for <br>clean energy generation.<br><br>
 
'''Replace''' - With the end of the fossil fuels nearing the search for (clean) alternatives continues. Although the<br>above visualised system can only be used in areas with large differences in height between high and low tide<br>(twenty locations worldwide, often deep bays) it can contribute to the replacement of current energy generating<br>facilities.<br><br>
 
'''Change''' - The use of water or the tides to generate electricity is more reliable then the sun and wind, because<br>water movement (especially the tides) is continuous, while the presence of the sun and wind are not. Using these<br>offshore underwater turbines can renew the attention for hydroelectric applications.<br><br>
 
'''Growth''' - Only twenty locations worldwide have been appointed to be able to use the current system. This has<br>directly to do with the necessary difference in height between the high and low tide (several dozens of<br>centimetres). Currently the application of the system is considered in Argentina, Australia, Canada, India, Korea,<br>Mexico, the UK, the USA, and Russia. Once the system gets improved it might be applicable in more locations.<br><br>
 
'''Other''' - The system is not yet sophisticated enough to offer a real attractive cost-revenue ratio. Furthermore<br>additional research needs to be done on the reliability of the hardware and its influence on the environment and<br>ecosystem.<br><br>
