Special Issue Information

Dear Colleagues,

The depletion of fossil fuel and concerns on global warming have increased worldwide interest in alternative fuel and energy systems. Although they produce little pollution and have large reserves, new energy currently has limited application due to its decentralized distribution, random production, and discontinuous generation. This determines the fundamental importance of studies and practices related to utilizing new energy in energy-efficient systems like smart grid and the worldwide energy web (InterGrid), where every individual can share sustainable energy resources.

The 2016 International Conference on New Energy and Future Energy System (NEFES 2016) is, thus, organized to provide a platform for researchers and practitioners in both industry and academia to brainstorm, share their latest achievements, and discuss the possible challenges in terms of new energy and future energy systems. NEFES 2016 aims to address various fields of new energy materials and resources, and networking and computing issues.

The topics of interest include, but are not limited to

Session I: New Energy

  • New energy resources

  • Advanced energy technologies

  • Energy management

Session II: InterGrid

  • Smart gird

  • Energy control and storage

  • Energy network

Session III: New Energy Material

  • Material for energy saving and sustainability

  • Techniques for developing new energy materials

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

In the present article, six symmetric compound parabolic solar concentrators (CPCs) with all-glass evacuated solar tubes (EST) as the receiver are designed, and a comparative study on their optical performance is performed based on theoretical analysis and ray-tracing simulations. In terms of optical loss through gaps of CPCs and optical efficiency averaged for radiation over the acceptance angle, CPC-6, designed based on a fictitious “hat”-shaped absorber with a “V” groove at the bottom, is the optimal design, and CPC-1, designed based on the cover tube, is the worst solution, whereas from the point of view of the annual collectible radiation on the EST, it is found that CPC-4, designed based on a fictitious “ice-cream” absorber, is the optimal design and CPC-1 is the worst solution. CPC-6, commonly regarded as the best design in the past, is not an optimal design in terms of annual collectible radiation after truncation. Results also indicate that, for high temperature applications, CPC-6 and CPC-4 are advisable due to the high solar flux on the EST resulting from the high optical efficiency for radiation within the acceptance angle.
