Dear Colleagues,

Climate change is a proven fact. There are many causes that are causing this climate change and one of the main ones is the uncontrolled emission of greenhouse gases into the atmosphere. The generation of energy for both domestic and industrial use through the use of fossil resources generates very significant amounts of greenhouse gases, and therefore this type of energy sources must either be improved or replaced by others with less environmental impact. These new energies are renewable energies. The changes in the form of energy generation are what will allow us to take care of the environment and continue conceiving life on the planet as we know it. Environment is crucial in our lifes from different point of view: it gives us the oxygen to breathe, the food to feed us and the raw materials to produce our products. In this context, our oceans occupy the seventy per cent of our world. Therefore, we must take advantage of their resources: marine biological species that can cure our diseases, alternative food (new ways of marine aquaculture), offshore energy (offshore wind, wave energy, tidal energy, gradients, currents, hydrogen, etc.), maritime transport (new types of vessels, new routes of transport, etc.), water pollution (plastics, waste, etc.), social aspects, etc. Papers related to these or similar topics are welcome to this Special Issue.

Topics of interest include, but are not limited to:

• Offshore wind energy;
• Wave energy;
• Tidal energy;
• Gradients;
• Currents;
• Combined systems;
• Maritime transport;
• New ways of marine aquaculture;
• Water pollution;
• Electrical engineering;
• Green hydrogen;
• Social aspects;
• Independent energy,

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
