Special Issue Information

Dear Colleagues,

Since the beginning of this century, renewable energy has been the fastest-growing energy source and demand has grown with the fast development in the industrial and transportation sectors. According to the C2ES, renewables made up more than 20 percent of net U.S. energy consumed globally for heating, power, and transportation. Nearly 60 percent came from modern renewables (i.e., biomass, geothermal, solar, hydro, wind, and biofuels). In the industrial sector, biomass accounts for 98 percent of renewable energy use, with nearly 60 percent derived from biomass wood, 32 percent from biofuels, and nearly 7 percent from biomass waste. In the transportation sector, the use of renewable fuels, such as ethanol and biodiesel, has increased significantly during the past decade. E85 (an ethanol transportation fuel) is expected to be the fastest-growing renewable energy type, growing at an average annual rate of 9.7 percent over the next 30 years. The International Conference on Innovations in Energy Engineering & Cleaner Production (IEECP’21) aims to investigate innovative applications and the latest research in the areas of energy production, alternative and renewable energy supply, energy savings analysis, cleaner production, and optimization of energy processes and environmental impacts.

This year, the IEECP Annual Conference will take place virtually in Silicon Valley, San Francisco, California, USA from 29 to 30 July 2021 and will be supported by the Energies journal. We encourage authors who will present an article at IEECP’21 and who feel that their contribution is within the scope of interest of the journal Energies to apply through the following link: https://www.mdpi.com/journal/energies/special_issues/IEECP21. Selected authors will be asked to submit an original and essential extension of their IEECP’21 paper to be considered for publication no later than 30 November 2021. More details can be found at https://www.mdpi.com/journal/energies/instructions#preparation. Accepted papers, after a process of peer-review by experts in the field, will be published in a Special Issue of Energies.
