An electricity substitution strategy that replaces fossil fuels such as coal and oil with electricity in end-use energy consumption, can effectively contribute to an energy transition and the early achievement of carbon peaking and carbon neutrality targets. As the benefits of electricity substitution are not synchronized across China’s regions, this paper uses a three-stage data envelopment analysis (DEA) model to measure the efficiency of electric energy substitution in 30 provinces of China in 2017. The results show that both environmental factors and random errors have significant effects on energy efficiency. After eliminating these influences, the efficiency of electrical energy substitution among regions presented the following pattern: “high in the east and low in the west”. According to the evaluation results, this paper proposes corresponding suggestions for the development of electrical energy substitution.

In 2020, despite the global economic crisis caused by the COVID-19 pandemic, it became clear that decarbonization and energy transition had become strategic goals rather than market trends. Moreover, they have become part of the broader and more ambitious plans of the world’s largest economies to move toward carbon neutrality by the middle of the 21st century. These economies include the European Union, the U.S., China, Japan and Korea. In Russia, these trends are typically viewed through the prism of risk: carbon neutrality implies a dramatic decrease in demand for fossil fuels, the production and export of which still play a key role in the Russian economy. However, apart from the risk to traditional sources of income, the global transition to carbon neutrality creates new opportunities for the development and diversification of the Russian economy, as well as for international cooperation in new areas. This article is devoted to the general identification of such opportunities. The authors perform a content analysis of the official plans of the largest economies related to achieving carbon neutrality by 2050–60. The main areas in which actions will be taken are identified. The current state of the corresponding industries in Russia and the possibilities for improvement are investigated. On the basis of this analysis, promising directions for the development of the Russian economy are proposed in which the implementation of large-scale international economic cooperation is possible in the coming decades.

The increased production of electrical energy will lead to an increase on the use of fossil fuels which ultimately raise the Greenhouse Gas (GHG) emissions. The use of fossil fuels (non-renewable fuels) for large-scaled generation of electrical energy will certainly cause problems considering oil and coal reserves as the main source for PLTU will shrink and run out over time. In addition, several environmental problems need to be considered and studied regarding this condition. Thus, it is very important to efficiently use electrical energy according to Presidential Instruction No. 6 of 2014 concerning energy development which focused on sub-sectors electricity development and minimization of fossil energy use as well as development of new, renewable, and converted energies. Based on this, a system which can support energy saving is needed. A system used for regulating energy needs is called the Energy Management System (EMS). The study was conducted in the Malang State Polytechnic Campus which is located on Jalan Soekarno Hatta no. 9, Jatimulyo, Lowokwaru Sub-district, Malang City. The sample used in this study consists of 230 people, including 150 students, 30 lecturers and 50 academics. This study is purposed to examine the correlation of the four variables to the energy management system and the use of environmentally friendly energy. Thus, the most appropriate model to accommodate this requirement is Structural Equation Modeling (SEM). The results of SEM analysis showed that the model of an environmentally friendly electric energy management is said to be feasible to be developed, thus it can be collectively adapted in all aspects for creating a green campus.

And Control

The increase in demand for electrical energy is increasing rapidly, in line with economic growth. In developing the electricity system, electrical energy service providers must provide electrical energy according to demand with good quality. The generation of conventional electric energy systems that use fossil fuels faces depleting fossil fuel sources, poor efficiency, and environmental pollution. This technology is known as Distributed Generation (DG). Distributed Generation (DG) or Micro Grid (MG) is a small-scale power plant located close to the load. The use of distributed generators can improve the entire system's efficiency, reduce transmission losses, reduce pollution, and ensure the continuity of the distribution of electrical energy. However, the drastic increase in the use of DG causes problems in the form of voltage and frequency stability which will be disturbed due to rapid changes in the generation and loading rates. If this is left unchecked, it can harm system security and reliability. A proper control strategy will restore system stability in the event of an imbalance.

Clean energy transition in islands is important and urgent in the current era of climate change. The possibility of de-carbonizing the heating and cooling sector in the island of Crete, Greece has been investigated. Fossil fuels are used in Crete in electricity generation, in heat and cooling production as well as in transportation. The use of various renewable and non-renewable fuels as well as the technologies used in heat and cooling generation has been examined together with the annual changes in fossil fuels consumption during the last years. Various renewable energies like solar energy, biomass and low enthalpy geothermal energy combined with renewable electricity could cover all the heating and cooling requirements in Crete totally eliminating the use of fossil fuels. Their technologies are mature, reliable, and cost efficient.  Renewable and low cost electricity can be easily generated by the abundant solar and wind energy resources in Crete powering electric systems generating heat and cooling. Current work indicates that the heating and cooling sector in Crete can be de-carbonized. This would result in the mitigation of climate change complying with the European goal for carbon neutrality in Europe by 2050.

Continuous Use

The continuous use of fossil fuels as energy source has depleted their level, and if used by the same rate, these forms of energy sources are going to become extinct in a few hundred years. In addition, the emissions generated from the usage of these fuels are adversely affecting the environment. Hence, governments has been forced to find other non-conventional forms of energy, which can be used sustainably. Due to its geographic location, Oman has a very high potential for renewable energies like solar and wind. Oman receives moderate wind speeds both offshore and onshore. On highways, the wind turbulence caused by fast moving cars would add up to the energy that can be obtained from the natural wind. This study focuses on harvesting of electric energy from the highway wind turbulence along with the normal wind breeze, and converting it into useful electrical energy. A comparative study was done between different types of wind turbines. Based on this study, a Savonius-type Vertical Axis Wind Turbine was selected to study and determine the amount of energy that can be generated along Muscat Expressway from the wind energy. The optimum location for the implementation of the designed VAWT was found out to be in the middle of the highways. The total electricity which can be generated was estimated to be around 1.063 kWh in one day using a single VAWT. It was found that the harvested electricity could be used to power the street lights on the highways if multiple VAWTs would be installed at regular intervals.
