recent developments in hydrogen production by thermochemical water decomposition are reported,with an emphasis on hydrogen production from non-fossil energy sources such as nuclear and solar. numerousdevelopments have been made on sulphur-iodine, copper-chlorine and other thermochemicalcycles. efforts are described to lower the temperatures required in thermochemical cycles, so as to broadenthe...

The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...

In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

Abstract This article aims to carry out a comparative analysis in the European Union and Romania, period 1991-2021, on achievement of ambitious energy efficiency objectives, by assessing assumed targets for primary final consumption at level years 2020 2030. Since 2007, EU leaders have been concerned about decarbonisation sector, first essential measure being reduce 20% 2020. As part objectives...

As we enter the post-pandemic period, United Nations' first priority related to sustainable development is facilitate a green transition, whereby “investments must accelerate decarbonization of all aspects our economy.” A 2009 study conducted by The Rocky Mountain Institute stated that “The role energy efficiency has historically played in US generally under appreciated. If productivity had rem...
