“…Tackling the climate change emergency requires a considerable change in the structure of energy systems and to replace fossil fuels by renewable energy sources. Concerns have been raised recently regarding the net energy [4][5][6] and macroeconomic implications of the energy transition [7][8][9][10][11] , because renewable energy systems have been traditionally thought to have substantially lower EROIs than fossil fuel-based energy systems 12 . Recent works have shown that such an understanding may be misguided, due to inconsistent comparisons whereby the primary-stage fossil fuel EROIs (fuels extracted, quantified at the mine or well mouth) are compared to the final-stage renewable energy EROIs (energy carrier delivered to the end user) 13,14 .…”

The net energy implications of the energy transition have so far been analysed at best at the final energy stage. Here we argue that expanding the analysis to the useful stage is crucial. We estimate fossil fuelsʼ useful-stage energy returns on investment (EROIs) over the period 1971–2020, globally and nationally, and disaggregate EROIs by end use. We find that fossil fuelsʼ useful-stage EROIs (~3.5:1) are considerably lower than at the final stage (~8.5:1), due to low final-to-useful efficiencies. Further, we estimate the final-stage EROI for which electricity-yielding renewable energy would deliver the same net useful energy as fossil fuels (EROI equivalent) to be approximately 4.6:1. The EROIs of electricity-yielding renewable energy systems, based on published estimations, are found to be higher than the determined EROI equivalent, even considering the effects of intermittency under a range of energy transition scenarios. Results suggest that the energy transition may happen without a decline in net useful energy, countering the view that renewable energy systems cannot replace fossil fuels without incurring a substantial energy penalty.

“…Final energy demand is expected to increase by about 1.8% per year, driven by the need for energy to support higher living standards, and accompanied by massive energy efficiency gains. There are studies such as (Dupont et al, 2021) present scenarios that are based on the possibility of an absolute decoupling between the production of goods and services and energy consumption.…”

Factors of investment in renewable energy and energy efficiency in Algeria

Our paper aims to identify the most important factors determining companies’ decision to invest in the energy transition in Algeria. Energy transition has been many governments’ main topic of interest over the last decades, climate change has led many of them to establish long-term plans for a successful energy transition; these plans aim to reduce greenhouse gas emissions following the guidelines of the COP21. Through a quantitative approach, we have addressed a questionnaire to different companies operating in Algeria and have obtained a total of 117 responses. The results show that financial, technical and regulatory factors have minimal impact on companies’ decision to invest in renewable energy and energy efficiency in Algeria. Further studies should explore other investment factors to help accurately determine those that significantly impact companies’ decisions to invest in Algeria’s renewable energy and energy efficiency. Furthermore, targetting one sector at a time and exploring the alternatives of foreign direct investment in renewable energy can result in higher efficiency.

“…and the CO 2 emissions released by their ever-escalating use threaten every aspect of human societies as well as a large part of the living world [2,3]. In this context, a rapid and global transition to low-carbon energy sources is deemed a necessity, although not without scrutiny of its feasibility [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Assessing Global Long-Term EROI of Gas: A Net-Energy Perspective on the Energy Transition

et al. 2021

Natural gas is expected to play an important role in the coming low-carbon energy transition. However, conventional gas resources are gradually being replaced by unconventional ones and a question remains: to what extent is net-energy production impacted by the use of lower-quality energy sources? This aspect of the energy transition was only partially explored in previous discussions. To fill this gap, this paper incorporates standard energy-return-on-investment (EROI) estimates and dynamic functions into the GlobalShift bottom-up model at a global level. We find that the energy necessary to produce gas (including direct and indirect energy and material costs) corresponds to 6.7% of the gross energy produced at present, and is growing at an exponential rate: by 2050, it will reach 23.7%. Our results highlight the necessity of viewing the energy transition through the net-energy prism and call for a greater number of EROI studies.
