“…In 2014, the global carbon emissions to the atmosphere were about 36 billion tons, which is approximately 1.6 times the 1990s rates, an increase which has been associated with average global temperature rises (Gamil et al, 2020). Close to 9,855 million metric tons of fossil-fuel based carbon dioxide emissions were emitted between 2013 and 2014, representing an increase of 0.8%.…”

Sustainable Energy Transition for Renewable and Low Carbon Grid Electricity Generation and Supply

The greatest sustainability challenge facing humanity today is the greenhouse gas emissions and the global climate change with fossil fuels led by coal, natural gas and oil contributing 61.3% of global electricity generation in the year 2020. The cumulative effect of the Stockholm, Rio, and Johannesburg conferences identified sustainable energy development (SED) as a very important factor in the sustainable global development. This study reviews energy transition strategies and proposes a roadmap for sustainable energy transition for sustainable electricity generation and supply in line with commitments of the Paris Agreement aimed at reducing greenhouse gas emissions and limiting the rise in global average temperature to 1.5°C above the preindustrial level. The sustainable transition strategies typically consist of three major technological changes namely, energy savings on the demand side, generation efficiency at production level and fossil fuel substitution by various renewable energy sources and low carbon nuclear. For the transition remain technically and economically feasible and beneficial, policy initiatives are necessary to steer the global electricity transition towards a sustainable energy and electricity system. Large-scale renewable energy adoption should include measures to improve efficiency of existing nonrenewable sources which still have an important cost reduction and stabilization role. A resilient grid with advanced energy storage for storage and absorption of variable renewables should also be part of the transition strategies. From this study, it was noted that whereas sustainable development has social, economic, and environmental pillars, energy sustainability is best analysed by five-dimensional approach consisting of environmental, economic, social, technical, and institutional/political sustainability to determine resource sustainability. The energy transition requires new technology for maximum use of the abundant but intermittent renewable sources a sustainable mix with limited nonrenewable sources optimized to minimize cost and environmental impact but maintained quality, stability, and flexibility of an electricity supply system. Technologies needed for the transition are those that use conventional mitigation, negative emissions technologies which capture and sequester carbon emissions and finally technologies which alter the global atmospheric radiative energy budget to stabilize and reduce global average temperature. A sustainable electricity system needs facilitating technology, policy, strategies and infrastructure like smart grids, and models with an appropriate mix of both renewable and low carbon energy sources.

Figure 5 (Lidsey, 2020;Lindsey, 2019) Figure 5 shows that the main element in greenhouse gases is carbon dioxide, followed by methane, nitrous oxides, CFC -11 and CFC-12 and other minor gases.…”

The purpose of this study is to review the role of energy in sustainable development by ensuring sustainability in electricity generation, supply, and consumption. Global electricity generation remains dominated by fossil fuels with renewable energy sources contributing a smaller proportion. Sustainable development needs sustainable energy which should be reliable, stable, good quality, affordable non-polluting and socially acceptable. Various measures can be put in place to limit emissions from various sectors. New technology should be developed and exploited for to maximize use of abundant but intermittent renewable sources a sustainable mix with limited nonrenewable sources optimized to minimize cost and environmental impact but maintained quality, stability, and flexibility of an electricity supply system. Other measures that can limit emissions include electrification of transport and industrial activities with electricity coming from renewable and low carbon sources. This review recommends the use of the three main strategies to minimize carbon emissions in the energy transition. These are conventional mitigation, negative emissions technologies which capture and sequester carbon emissions and finally technologies which alter the global atmospheric radiative energy budget to stabilize and reduce global average temperature.

“…Gamil et al [17] proposed the optimal scale and planning strategy for a fully hybrid renewable energy power system on remote islands in Japan. The system consisted of the combination of photovoltaic (PV) power, a wind turbine generator (WG), a battery energy storage system (BESS), a fuel cell (FC), a seawater electrolysis plant, and a hydrogen tank.…”

This article proposes a plan to replace real-time power with constant power from the grid to reduce costs and reduce the impact of the micro-grid on the main grid at the same time. Most of the peak electricity consumption periods of universities or some enterprise institutions are during the daytime. If solar energy can be used reasonably at this time, it can provide a good guarantee of peak power. In this study, a grid-linked solar-plus-storage micro-grid was used to supply power to a university located in Okinawa, Japan. The non-dominated sorting genetic algorithm II (NSGA-II) was used to optimize the model size, and the loss of power supply probability (LPSP), life cycle cost (LCC), and waste of energy (WE) were taken as the optimization indicators. For this study, three scenarios were considered where the first scheme (Case 1) was a comparison scheme, which used a PV battery and real-time power from the infinity bus. Both the second and third cases used constant power. While Case 2 used constant power throughout the year, Case 3 used daily constant power. The optimal solutions for the power supply units were grouped into three cases where Case 1 was found to be the most expensive one. It was found that the costs of Cases 2 and 3 were 62.8% and 63.3% less than Case 1. As a result, the waste of energy was found to be more significant than Case 1: 70 times and 60 times, respectively. On the contrary, Case 1 had 15.2% and 16.7% less carbon emissions than Case 2 and Case 3, respectively. This article put forward the idea of constant power supply growth at the financial markets, which breaks the traditional way in which the power supply side follows the user’s consumption. While reducing costs, it reduces the impact on large-scale power grids and can also ensure the reliability of campus microgrids.
