Magnetic refrigeration (MR) at room temperature is an emerging technology and shows real potential to enter conventional markets. The principle of MR obeys the magnetocaloric effect (MCE), which is based on the effect caused by a magnetic field on the materials that bear the property of varying...

This paper aims to provide the current state of the art of solar adsorption refrigeration systems operating with the single-bed intermittent cycle (also known as basic cycle). A comprehensive literature review has been conducted and it was concluded that this technology, although attractive, has...

Demand side management (DSM) can be defined as modifications in the demand side energy consumption pattern to foster better efficiency and operations in electrical energy systems. DSM activities, which are classified into “energy efficiency (EE)” and “demand response (DR)” are becoming...

Most commentators expect improved energy efficiency and reduced energy demand to provide the dominant contribution to tackling global climate change. But at the global level, the correlation between increased wealth and increased energy consumption is very strong and the impact of policies to...

Satisfying energy requirements in its most suitable form is the great challenge of the world in the 21st century. Moroccan authorities are fully aware about this challenge, especially with the population and economic growth that causes a sharp increase of energy demand. This paper presents the...

Local level actors have an important role in developing small-scale energy innovations as well as disseminating the gained knowledge to key audiences. Diffusion of these energy solutions from innovators and early adopters to wider user groups has often been slow. This study explores the...

It is well known that rooftop solar thermal panels increase both power rates of circulation pumps and initial investment cost of solar assisted ground source (geothermal) systems. To avoid both of them it means that the unnecessary energy consumption rates of circulation pump(s) and their...

It is well established that ground-source heat pumps (GSHPs) require less external energy input than conventional heating and cooling systems for buildings because they exchange heat with the subsurface soil and rock, which has a steady temperature compared to that of the outside air. To address...

Though improving energy efficiency is an important approach to decrease the energy consumption, the rebound effect caused by technology progress negatively affects the effectiveness of energy efficiency policies. This paper empirically investigates direct rebound effect of urban residential...

Industrial processes account for one-third of global energy demand. The iron and steel, cement and refining sectors are particularly energy-intensive, together making up over 30% of total industrial energy consumption and producing millions of tonnes of CO2 per year. The aim of this paper is to...
