Dear Colleagues,

Hydroelectric generation plays an important role in many power systems, mainly due to its capability to provide medium-term energy storage (hours  or days). In this way, it can contribute to integrate non-manageable energy sources in power systems. In addition, hydroelectricity is, in itself, a renewable energy source. However, this does not mean that it is environmentally benign.

Climate change may continue being the bigger long-term concern; however, in the medium and short term, oil and gas shortage is the most pressing concern. Thus, any advance in any technology that can contribute to reduce world dependency on fossil fuels is extremely valuable. These advances can provide higher efficiency and lower costs, and use less materials or more robust devices. Furthermore, any submissions on the reduction in environmental or society impacts are also welcome.

As it is well known, advances have to be disseminated for being useful. Five years ago, this journal published an Special Issue on “Hydropower and Sustainability”. The purpose of this Issue is to reexamine this topic and its contributions to advance the sustainable generation of hydroelectric 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. Sustainability 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 2400 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.
