Objective Representation

A single paragraph of about 200 words maximum. For research articles, abstracts should give a pertinent overview of the work. We strongly encourage authors to use the following style of structured abstracts, but without headings: (1) Background: place the question addressed in a broad context and highlight the purpose of the study; (2) Methods: describe briefly the main methods or treatments applied; (3) Results: summarize the article’s main findings; and (4) Conclusions: indicate the main conclusions or interpretations. The abstract should be an objective representation of the article; it must not contain results that are not presented and substantiated in the main text and should not exaggerate the main conclusions.

Reducing Energy

Next to climate change on the list of challenges faced by humankind in today’s technological age is energy management. While “smart” ideas continue to gather momentum as some of the ways earmarked to combat the menace of a changing climate, coupled with efficient management of energy, research and development in the blockchain is not retracting, recently giving rise to digital currencies capable of fueling massive energy consumption via mining of “crypto-coins”. Given that sustainability is a crucial goal in the design of smart cities nowadays, there are currently no assurances of sustainable cities where cryptocurrency mining is at full scale. Nevertheless, alternative energy sources may come to the rescue in no distant time. In this paper, we contextualize energy-use in smart cities through mining of virtual currencies, in order to predict whether or not smart cities can truly be sustainable if crypto-mining is sustained. An attempt is also made to emphasize the possible ways of reducing energy use and all activities involving digital currencies by seeking to replace “Proof of Work” (PoW) with improved alternatives.

Hybrid Renewable Energy

The demand for electricity is increasing day by day and canNot be satisfactorily met without Non-renewable energy sources. Renewable energy sources such as wind and sun are universal and environmentally friendly. These renewable energy sources are the best options for meeting global energy needs, but they are unpredictable due to natural conditions. Using solar and wind hybrid renewable energy systems is the best option to take advantage of these available resources. This article introduces wind energy conversion systems, solar energy conversion systems, and multistage inverters.
