There exists a wide energy supply/demand gap in Nigeria. The local generation of electricity meets only 31% of the demand of 10000 MW. By contrast, only 39.6% of the total installed capacity for electricity generation is achieved, owing to aging infrastructure, etc. The energy demand/supply pattern and infrastructure critically reviewed thus suggested the need to increase the electricity generation capacity. Furthermore, Nigeria flares 77% of her associated natural gas. Apart from the environmental penalties that flaring represents, in monetary terms, over the 110 years' life of Nigeria's gas reserves, a conservative estimate of the cost of the gas so-flared was $330 billion (based on $20/barrel average price of crude). It was safely inferred that the way forward in meeting the country's energy demand should include a strong element of gas utilization. In previous publications by this group, it was established that while domestic cooking could reduce the flared gas by about 5.4%, a cohesive policy on associated gas use for electricity generation could eliminate gas flaring. For domestic utilization of the associated gas, burner design and safety concerns were identified as the key challenges to overcome. The paper reports the effectiveness of odorizers in leakage detection/ prevention by the local consumers. It also discusses the issue of prevention of gas explosions. The previous cases of gas accidents were reviewed. The safety approaches proffered in the paper identified the relevant areas of research for safe delivery and consumption of natural gas in Nigeria.

Subject Energy diversification efforts. Significance The El Nino weather phenomenon has laid bare the vulnerabilities of South America's dependence on hydropower. Gas has been the primary back-up, and liquefied natural gas (LNG) import capacity a strategic necessity (one which the northern part of the continent lacks). However, a recovery in Argentine gas production could eventually change the region's current gas balance, while the growth of renewables offers a new, indigenous, low-cost energy source. Impacts Investment in LNG import capacity and gas storage will continue. However, facilities face the threat of low utilisation as renewables capacity and domestic gas production increases. As one of the cheapest forms of electricity generation with a large amount of unexploited resource, hydropower will expand. States will gradually look towards other forms of system flexibility and grid resilience.

Electrical Energy Generation

Electric energy is very important both technologically and economically in today's countries. Countries can generate and consume more energy according to their level of development and the resources they have. In the literature, it is estimated in parallel with the development of countries; there will also be an increase in electrical energy generation and consumption. Similarly, in economies that generate and consume more electricity, it is assumed that this will affect their economic growth. But these assumptions need to be calculated econometrically. This study has been prepared for this purpose. In this study, the relationship between electricity generation, electricity consumption, and economic growth in Turkey was analyzed. In the analysis conducted for the period 1975-2019, the Toda-Yamamoto causality test method was preferred as the method. As a result of the analysis, it was determined that there is a causal relationship from electricity consumption and electricity generation to economic growth, valid for the period 1975-2019 in Turkey.

The study carried out here aims to determine the advantage of using in-situ electricity generation facilities versus conventional generators, being evaluated from the environmental point of view. For this, an environmental analysis on the production of CO2 has been applied to two scenarios of electricity generation for a residential building in Medellin city (Colombia). The first one refers to La Sierra thermo-electric plant located in La Sierra, municipality of Puerto Nare, in the Antioquiashire, which is the most efficient plant in Colombian thermal generation. The second comparison scenario refers to the annual operation of a micro-cogeneration facility, which satisfies the building’s hot water and electrical energy needs. Using the capabilities of the TRNSYS v17® energy simulation software and the emission equations available in the public domain, the comparative environmental analysis is carried out between one and the other for the same load. The losses in electric transmission are assumed to be 10%. This analysis has shown a difference of more than 50% in emissions generation, with the main cause being the amount of fuel used, which for both cases is natural gas. On the other hand, this study shows the environmental advantages in the use of in-situ generators, decreasing transmission losses.

Weather Scenario

The current study applies an energy-system model to explore energy supply options in meeting Tanzania’s electricity demands projection from 2010 to 2040. Three economic scenarios namely; business as usual (BAU), low economic consumption scenario (LEC) and high economic growth scenario (HEC) were developed for modelling purposes. Moreover, the study develops a dry weather scenario to explore how the country’s electricity system would behave under dry weather conditions. The model results suggests: If projected final electricity demand increases as anticipated in BAU, LEC and HEC scenarios, the total installed capacity will expand at 9.05%, 8.46% and 9.8% respectively from the base value of 804.2MW. Correspondingly, the model results depict dominance of hydro, coal, natural gas and geothermal as least-cost energy supply options for electricity generation in all scenarios. The alternative dry weather scenario formulated to study electricity system behaviour under uncertain weather conditions suggested a shift of energy supply option to coal and natural gas (NG) dominance replacing hydro energy. The least cost optimization results further depict an insignificant contribution of renewable energy technologies in terms of solar thermal, wind and solar PV into the total generation shares. With that regard, the renewable energy penetration policy option (REPP), as an alternative scenario suggests the importance of policy options that favour renewable energy technologies inclusion in electricity generation. Sensitivity analysis on the discount rate to approximate the influence of discount rate on the future pattern of electricity generation capacity demonstrated that lower values favour wind and coal fired power plants, while higher values favour the NG technologies. Finally, the modelling results conclude the self-sufficiency of the country in generating future electricity using its own energy resources.

Electric energy is an important factor for human needs, functions as lighting, and various human activities. The large amount of electrical energy needs demands to create various alternative electrical energy. Alternative energy uses renewable energy sources to avoid crisis and energy scarcity. The National Energy Policy (KEN) has encouraged the government and the private sector and the public to use energy effectively and efficiently, and to utilize renewable energy. The direction of national energy policy includes reducing dependence on fossil fuels, specifically petroleum. Utilization of renewable energy is needed for the sustainability of national energy supply and reserves. Indonesia is called a maritime country, because 2/3 of Indonesia’s territory is the sea with the longest coastline in the world, which is ± 80,791. 42 Km and is also called an archipelagic country because it has thousands of islands. This natural situation is a great potential for the development of renewable energy, especially the energy sourced from the sea spread wide and very abundant, namely solar pond. One of the alternative sources of renewable energy sourced from the sea currently not developed in Indonesia is solar ponds, even though Indonesia has a huge geographical potential to develop this technology. There are at least two potential parameters for building a solar pond, first because Indonesia has a tropical climate with a large enough intensity of sun, second because Indonesia is a maritime country surrounded by sea, so the availability of raw water is very abundant. Solar pond is not a new power generation technology. In the history of electricity generation technology in Indonesia, this technology has never been tested and implemented at all. In this study, it has a long-term goal of generating electricity from solar ponds. Solar pond technology is a type of environmentally friendly power plant, based on seawater using sunlight to get the difference in heat in the solar pool so that the thermal layer can be converted into electrical energy. The specific targets, namely data salinity and temperature data on the prototype solar pond have been realized in the form of cylindrical with a height of 1. 05m and a diameter of 0. 8 meters. Solar pool research, in line with the goal of national transformation as a significant contributor to the benefit of the Indonesian Maritime Continent. In line with the development of electricity generation technology, solar pond technology has never been implemented in Indonesia, so this research is in accordance with the 2016-2020 National Strategic Plan number 51868 / UN4. 1 / PR. 04 / 2016.

Coal and coal-fired electricity generation, as interdependent upstream and downstream industries, play a positive role in ensuring energy security, economic development and social stability in China. However, the strategies of coal enterprises and coal-fired power enterprises are influenced by the market structure, coal-electrical energy policies and the characteristics in the coal-electricity energy supply chain. In this paper, considering the upstream for many coal enterprises, the downstream for many coal-fired electricity generation enterprises in coal-electricity energy supply chain model, is concluded that profit calculation model for coal-electricity cooperative enterprises, independent upstream coal enterprises, and independent downstream coal-fired electricity generation enterprises were obtained. In order to maximize the profits, we construct coal enterprises and coal-fired electricity generation enterprises cooperative operation decision-making model, and the different situation of the optimal strategy is studied and analyzed. Using Matlab simulation software for numerical simulation. It is to belong to the simulation results confirm the efficiency of the model.
