IMPACT FACTOR 2.702 an Open Access Journal by MDPI Tidal Turbines Guest Editors: Message from the Guest Editors Prof. Dr. Guillou Sylvain Dear colleagues, Ecole d'Ingénieurs (ESIX Normandie), Université de Caen Tidal turbines generate energy from tidal currents. One of Normandie, 50130 Cherbourg-en- the major interests of this renewable energy is its Cotentin, France predictability. With its predictability, tidal turbines are [email protected] ideally suited to be integrated with smart grids. The areas Dr. Eric L. Bibeau of interest for the installation of these devices are spread Department of Mechanical all over the world. They are characterized by a complex Engineering, University of bottom morphology and flow due to currents which can be Manitoba, Winnipeg, Manitoba, disturbed by waves, the presence of sediments, or objects R3T 2N2, Canada transported by the flow. The design, positioning of the [email protected] turbines, maintenance, and interactions must consider these aspects. At present, the cost of tidal turbines is higher than that of technologies such as wind turbines, and Deadline for manuscript reducing this cost remains a challenge from the design of submissions: the machine to the installation and maintenance 20 March 2021 operation. mdpi.com/si/44926 SpeciaIslsue IMPACT FACTOR 2.702 an Open Access Journal by MDPI Editor-in-Chief Message from the Editor-in-Chief Prof. Dr. Enrico Sciubba Energies is an international, open access journal in energy Room 32, Department of engineering and research. The journal publishes original Mechanical and Aerospace papers, review articles, technical notes, and letters. Authors Engineering, University of Roma Sapienza, Via Eudossiana 18, are encouraged to submit manuscripts which bridge the 00184 Roma, Italy gaps between research, development and implementation. The journal provides a forum for information on research, innovation, and demonstration in the areas of energy conversion and conservation, the optimal use of energy resources, optimization of energy processes, mitigation of environmental pollutants, and sustainable energy systems.
