Dear Colleagues,

Energy is a vital component of social/economic growth and a driver in raising living standards. Conventional fossil fuels are finite and non-renewable, using them adds to greenhouse gas pollution in the atmosphere, which drives up global temperatures. Therefore, the integration and growth of renewable energy technologies and systems has become critical for preserving the potential of keeping global warming to 1.5 degrees Celsius and ensuring a worldwide net zero emissions trajectory by the middle of the century. These innovations are at the forefront of enabling a fair and just shift to a low-carbon economy.

There are various forms of renewable energy sources (solar, wind, hydro, geothermal, biofuels, wave, tidal, and others) that can be incorporated to minimize the use of fossil fuels. In addition to sustainable energy generation, a promising solution to store sustainable energy is crucial. Clean fuels and battery energy storage are good options for several power systems to store different amounts of energy for short and long durations. There are various systems and concepts that can be employed to take advantage of clean sources such as solar PV panels, wind turbines, fuel cells, hydropower systems and hybrid/integrated energy systems. To conclude, the increasing deployment of renewable energy and green technology is important to tackle greenhouse gas emissions, reduce air pollution and expand energy access.

This Special Issue aims to showcase the latest research achievements in the development of renewable energy technologies, as well as applications and perspectives of sustainable energy systems. The potential topics of interest for this Special Issue include, but are not limited to, the following:

• Novel concepts and ideas related to renewable energy technologies;
• Sustainable technologies for the decarbonization of power systems;
• Integrated assessment and modeling of renewable energy systems;
• Technical, economic and environmental analysis of renewable energy technologies and hybrid systems;
• Integration of renewable energy sources and energy storage technologies;
• Case studies demonstrating the implementation of renewable energy technologies;
• Best-practice analysis and review of green technologies and solutions;
• Fuel cell systems and integrated clean systems;
• Hybrid energy systems that are based on clean fuels.

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. Applied Sciences 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.
