Dear Colleagues,

The need for widespread implementation of renewable energy technologies has become a global challenge as we transition to a low carbon and green economy. Around 176 countries have stated their renewable energy targets, driven by various motivations. Renewable energy technologies are regarded as one of the pathways to decarbonize the energy sector and to reduce fossil fuel dependency. Traditionally, renewable energy plays a vital role as an energy source in rural areas of developing countries. At present, one of the key challenges to adopting alternative options is the cost effectiveness for sustainable development.

The following areas of technologies could be included in this proposed issue for a wider spectrum of researchers and policy outlooks.

1. Renewable energy economy analysis: modeling, investment, and policy assessment;
2. Life cycle analysis/life cycle management in renewable energy applications;
3. Economics of 4th-generation biodiesel;
4. Biomass to biodiesel or bioethanol;
5. 3rd-generation bioethanol production;
6. Waste plastics to fuel production economics;
7. Municipal green waste and solid waste to fuel production technologies and economics;
8. Agro-farm or industrial emission reduction technologies leading to renewable economic emergence;
9. Grid-tied/off-grid solar energy economics;
10. Economics of renewable energy storage: solar to hydrogen fuel cell, nuclear to hydrogen, biomass to hydrogen, biofuel (bioethanol, biomethane, biodiesel) to fuel cell technology, alternative fuels to fuel cell production;
11. Carbon capture technologies and economics from biofuels;
12. Transition to renewable or cleaner energy production activities.

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.
