The p-Si/methanol interface in the presence of redox couples was studied by means of impedance, open-circuit photovoltage and cyclic-voltammetric measurements. Evidence was found for the occurrence of an inversion layer underneath the Si surface under certain circumstan...

In this study an assessment of investments in a hydropower plants is considered. The objective of this work is to maximize the net present value from selling energy. Because of the stochastic nature of river flows, flow duration curve is constructed to take into account...

The monitoring and targeting methodology consists of a systematic approach on energetic resources use in order to achieve the best economic result. This paper shows an overview of a framework for an automated energy monitoring and targeting system which is compatible wi...

At present, the photovoltaic power is subject to a number of discussions in domestic, as well as foreign studies and expert publications. Despite the conditions of the sunshine in the Slovak Republic, which are better than in the Czech Republic or Germany, Slovakia keep...

This paper investigates the impact of second-generation (SG) plug-in battery electric vehicles (PBEVs) on distribution transformers insulation life considering the time-of-use (TOU) prices. The effect of dual Level 2 charging, 3.7kW, and 6.6kW on the loss of life (LOL) ...

Abstract Heliostat reflective facets have traditionally been constructed with glass/silver and metal back support, which may be near reaching its minimum cost point. During the past year, Sandia National Laboratories evaluated alternative low-cost materials and manufact...

In this paper, we present our vision of what kind of wearable devices and how they can be powered by the heat of human beings and by using ambient light. The basic principles of designing body-powered devices and ways of their hybridizing with photovoltaic cells are dis...

Abstract Fuel cell vehicles have reached the commercialization stage and hybrid vehicles are already on the road. While hydrogen storage and infrastructure remain critical issues in stand alone commercialization of the technology, researchers are developing onboard fuel...

Abstract Cold tolerant sugarcane ( Saccharum spp.) cultivars are important in sub-tropical production areas because they can extend the growing and harvest seasons, and increase ratooning ability. Improved cold tolerance in Saccharum species has the potential to expand ...

This presentation was part of the SP5 & SP6 WORKSHOP on System Integration – Expert Workshop: “Wind & Power-2-X”.

Publisher Summary There are many controversial issues in terms of the energy problem. Energy suppliers are now forced to take into account environmental effects and safety at the cost of less commercial profit. Although they intend to build more nuclear plants, it is so...

Microgrids expansion problems with battery energy storage (BES) have gained great attention in recent years. To ensure reliable, resilient, and cost-effective operation of microgrids, the installed BES must be optimally sized. However, critical factors that have a great...

Abstract The Indus Basin of Pakistan with 800 hydropower project sites and a feasible hydropower potential of 60 GW, 89% of which is undeveloped, is a complex system poised for large-scale changes in the future. Motivated by the need to understand future impacts of hydr...

Abstract This study investigates the effect of different mixing strategies on anaerobic digestion of food waste in order to make the anaerobic digestion waste-to-energy process more energy efficient. Results showed that intermittent mixing is an alternative strategy to ...

Congratulations! You are reading a book about a technology that has changed the way we think about energy. Solar electricity, also known as photovoltaics (PV), has shown since the 1970s that the human race can get a substantial portion of its electrical power without bu...

The article describes a newly developed calculation technique and choice of the geometrical parameters of the solar collector with the siphon effect. The dependence of the cross section of the pipe on the flow time for different values of the head is also shown. With an...

<jats:sec><jats:title>Abstract</jats:title><jats:p>Over the past decade, multiple attempts have been made to curb North Korea's development of a nuclear program. Major world powers such as the United States and China have reached out to Pyongyang through bilateral and m...

Abstract In this article, quasi-oppositional teaching learning based algorithm (QOTLBO) is proposed to solve thermal unit commitment (UC) problem. Teaching learning based algorithm (TLBO) is a recently developed meta-heuristic algorithm based on the effect of the influe...

Abstract Nowadays the concept of intelligent homes and smart technologies are spreading out and becoming a vital strategy to optimize the energy performance. Specially that the internet is available to all our life aspects including educational system, health care, bank...

Abstract This paper reports recent efforts made by the mining industry in adapting and applying photovoltaic (PV) and wind power systems at operating and abandoned mines around the world. Several applications of PV systems have been found at operating mines such as the ...
