“…The weighted total energy and exergy efficiencies in the residential sector for various countries and periods are presented in Table 4. Badmus and Osunleke [15] studied the overall energy and exergy analyses for the whole Nigerian residential sector in 1991-2005. They found that the overall utilization energy efficiency was 19.89%, and the exergy efficiency was 4.38%.…”

Exergy and Economic Analysis of Energy Consumption in the Residential Sector of the Qassim Region in the Kingdom of Saudi Arabia

The Kingdom of Saudi Arabia (KSA) is considered one of the countries with the highest consumption of electric energy per capita. Moreover, during the period of 2007–2017, the consumption rate increased from 6.9 MWh to 9.6 MWh. On the other hand, the share of residential electricity consumption in the KSA constitutes the biggest portion of the total electric consumption, which was about 48% in 2017. The objectives of this work were to analyze the exergy and assess the economic and environmental impacts of energy consumption in the residential sector of the Qassim region to determine potential areas for energy rationalization. The consumption patterns of 100 surveyed dwellings were analyzed to establish energy consumption indicators and conduct exergy analysis. The performances of different consuming domestic items were also examined, and energy efficiency measures are proposed. The average yearly consumption per dwelling was determined, and the total energy and exergy efficiencies are 145% and 11.38%, respectively. The average shares of lighting, domestic appliances, water heaters, and air conditioning from the total yearly energy consumption were determined.

“…Based on [34], LPG stove cooking efficiency is taken as 45% and HHK stove cooking efficiency as 35%. In a similar vein, according to [39], quoted in [40], the lighting efficiency of a kerosene lamp is 0.05% and its exergetic efficiency is 0.045%. Since efficiency is ratio of output to input, the energy efficiency η is, simply:…”

Household kerosene and Liquefied Petroleum Gas form the bulk of domestic fuels, especially in Nigerian urban areas. Data on both fuels, from 1980 to 2019, were collected, mainly from Nigerian National Petroleum Corporation sources. Energy, exergy and environmental compatibility analyses were carried out on the utilisation of LPG for cooking, and household kerosene for both cooking and lighting. Kerosene lighting, with 0.05% energy efficiency and 0.045% exergy efficiency, was extremely poor. Cooking, with different mixes of both fuels, yielded energy efficiencies ranging from 35.04% to 44.54%. Corresponding exergy efficiencies were from 7.75% to 9.98%. Associated environmental compatibility factors were from 0.71749 to 0.73945. Overall process energy efficiencies, involving both cooking and lighting, were from 4.05% to 34.19%. Corresponding exergy efficiencies were from 0.93% to 7.61%. Overall environmental compatibility factors ranged from 0.71746 to 0.73259. Energy and exergy efficiencies, as well as environmental compatibility factors, increased directly with increase in LPG utilisation in the fuel-mix.

“…It revealed the 1900-1998 energy (exergy) efficiency curve for the USA, where the 25-year curve, in general, tends to form a straight line. Assumption strengthened after studying research results, among others (Badmus and Osunleke, 2010;Chowdhury et al, 2019;Chowdhury et al, 2020;Kondo, 2009;Mitra and Gautam, 2014), regarding other efficiencies. The estimation results using formula ( 23) are then compared with the results of historical efficiency improvements on average: 1 [%/year] (Gilli et al, 1995…”

Quantification of global sustainable energy security (ES) becomes urgent, but the concepts of ES are still not clear. Thus, this paper is originated from philosophical ES studies, in which the various concepts came from the differences in determining the observed multi-matters (energy, equipment, human, and ecosystem: EPME) and point of view to see the EPME. Therefore, this research is aimed at measuring the EPME variables, producing ES material quantities (Q es ). Q es is derived after a 4-stage unification and is defined in a formula. The formula is then applied to calculate the top ten populous nations in the world from 1990 to 2015. Based on the top Q es values, the rankings are Russia (Fed.), USA,
