Nepal is 100% dependent on imported petroleum products as it has no as yet viable proven reserve. The import of petroleum is increasing at an alarming rate (15.2% annually) which is creating not only a burden on the national economy but also raising the issue of energy supply security and environmental degradation. In this study, eleven distinct significant indicators have been used to evaluate the energy security status of the country. Since there is no such detailed quantification of indicators carried out in previous research, this study can be a significant input to policymakers and planners. It also explores the policy intervention measures to improve energy security status in the context of a developing country that is increasingly dependent on imported commercial fuels. Five different scenarios have been developed considering 2017 as a base year and 2040 as an end year with different economic growth rates 4.5%, 7.2% and 9.2% as main driving parameter. Two additional policy intervention scenarios (Policy-I and Policy-II), prioritizing electrification to enhance energy security, have been analyzed. The energy demands have been projected using the Model for Analysis of Energy Demand (MAED), while the Low Emission Analysis Platform (LEAP) tool has been used to analyze the supply, the energy supply requirement, fuel import dependence, cost, as well as the size of power plant requirement under different scenarios. The results manifest that there would be a reduction in Total Primary Energy Supply (TPES) requirement by 1.14% and 8.7% under policy-I and Policy-II scenarios respectively in the year 2040, compared to the reference scenario (7.2%) resulting in improved energy security, economic vulnerability, and GHG mitigation. It indicates that the use of indigenous renewable energy resources mainly hydro is indispensable for ensuring the energy security of Nepal.

This paper investigates the impact that economies of scale have had in the success of the wind industry in the United States since 1980 including the trend to larger wind turbines and wind farms and assembly learning curve effects. Analyses utilize average U.S. wind industry historical data to assess past performance and predict the future economic potential for both onshore and offshore wind turbine industries. The intent of this analysis is to serve as a case study to demonstrate the importance of selecting the right product design platform and how the ability to scale a technology can impact the success of products and, in this case, an entire multi-billion dollar industry. From the early stages of development, the wind industry recognized this opportunity and enabled the commercialization of larger and larger wind turbines and subsequently exploited the significant economies of scale possible in producing low-cost electricity via large, horizontal axis turbines and associated wind plants. The cost to produce electricity was reduced more than six-fold over this timeframe and is competitive today with conventional fossil-fuel power generation alternatives. The physics of horizontal axis wind turbines enables them to scale up disproportionately in electric power output and annual energy production with increased size/nameplate rating.

Power load forecasting plays a critical role in energy economy development and distribution of power systems. Predicting medium and long term power loads have facilitated the development of power grids. In this paper, a stacked-gated recurrent unit (Stacked-GRU) is applied to establish a power load forecasting model by integrating economic factors. Meanwhile, it also conducts medium and long term power load (MLTPL) forecasting based on the power load data of Yunnan Province from 2009 to 2020. By comparing different optimizers, it is found that the Adam optimizer works the best on the Stacked-GRU architecture. In the experiment of medium and long term power load forecasting for Yunnan Province, the values of MAPE, RMSE, and MAE of the model are 9.76%, 1.412, and 1.14, respectively, all of which outperform other deep learning comparison algorithms.

The construction of the digital village is a combination of the concept of digital economy and the strategy of rural revitalization, which requires a correct understanding and scientific evaluation. Taking Zhejiang Province as the research object, based on the actual situation and the connotation of digital villages, a digital village indicator system was constructed from the two dimensions of digital village development capacity and development effectiveness, and the relative entropy TOPSIS method was used to analyze the digital villages in Zhejiang Province from 2016 to 2019. Compare and evaluate the development level. The results show that the development of digital villages in Zhejiang Province has achieved remarkable results, and the development level of digital villages has been improved year by year. Among them, the index scores of industry digitalization, governance digitalization, service digitalization, digital life, agricultural production, farmers’ prosperity, and rural prosperity have achieved stable or rapid growth. The close value of TOPSIS is increasing year by year. Finally, it puts forward countermeasures and suggestions to promote the development of digital villages across the country.

Due to the development of the times and the rapid pace of life in the modern society, the living standards has become higher and higher, and various types of self-driving travel have begun to increase. However, at present, most rural areas do not have good infrastructures, tourist introduction platforms and tour guide services for tourism, and there is no effective guidance service for the rural complex traffic environment, so these problems restrict the development of rural tourism. In view of these problems, in this paper, the rural tourism information service system based on SOA technology framework was designed and developed to provide tourists with convenient services and to attract more tourists.

Today, energy is as important as labour, capital and technology for the growth of countries. As countries grow economically, they try to achieve the same or more amounts of output with fewer inputs. In other words, countries target efficiency based growth. As the economic growth of countries increases, their energy requirements also increase. Regarding countries that are not rich in domestic resources, this increase, imposes significant costs. On the other hand, the finite energy supply in countries rich in domestic resources is an important problem. That is why the phenomenon of renewable energy has become a trend all over the world. In addition to reducing import dependence on energy, new policies are required to reduce the effects of climate changes and to protect natural resources. That is why; renewable energy and economic efficiency are an attractive research area. In the study, efficiency scores were obtained by calculating the Malmquist total factor productivity index in the period 1992–2018 for 10 countries among the N11 countries. Then, the efficiency values obtained by using the two stage estimation method were used as the dependent variables. The test results based on Tobit regression indicated that the increase in the supply of renewable energy positively increases economic efficiency. It can be said that the supply of renewable energy will lead to economic efficiency in the future.

Most of the travel demand in developing countries is fulfilled by private vehicles dominated by 2-wheelers due to their affordability, accessibility, and availability, which has direct effects on energy, economy, and environment. To achieve sustainable transport, policies such as electric mobility and mass transport options have been implemented which are mainly focused on technology shift based on technology cost and environmental externalities. Transport modelling in this study was carried out using an additional attribute: travel time which shows the impact of travel behaviour on the optimal modal mix and the consequent impact on energy and emissions. The scenario-based approach using the travel time budget (TTB) concept was used using a bottom-up TIMES modelling framework. The scenario analysis shows the trade-off between the speed of the vehicle, available travel time, and sustainability in transport. The result suggests that the investment in rapid transit would be the potential future mode in Kathmandu valley.

The smart grid is playing a game-changing role in achieving clean and green energy, infrastructure, and cities, which are all part of the sustainable development goals. The significance of communication infrastructure in the reliable design and operation of the smart grid is well recognized, notably for renewable integration, facilitating distributed energy resources and storage, demand response, and energy efficiency. Since choosing the optimal communication technology is a strategic decision, the problem needs careful investigation, taking into account realistic data traffic estimates to fulfill the communication needs of the applications envisaged. Even though a vast array of technologies with diverse capabilities is available to meet such communication needs, choosing the optimal wireless technology for a smart grid project remains a difficult challenge. In this context, to achieve and maximize the benefits of the smart grid and its applications, a systematic and efficient approach is necessary. This study proposes a data-driven decision-making approach for evaluating the capabilities of viable wireless technology options and selecting the most suitable option for the smart grid project at the design phase. The suggested approach and the decision-support tool were developed using a cost-function-based optimization technique. A case study of Siliguri city Indian smart grid pilot is discussed to validate the potential and aptness of the presented approach and suggest better technology alternatives as replacements. Being field data-driven, the presented optimization approach is simple, customizable, strategic, and re-usable with practical efficacy to assist decision-making.

The main purpose of the study conducted in the article is to study the nature of Ukrainian consumption of fashion industry goods for “consciousness” and to determine the present and prospect trends of development. To achieve this goal, the next tasks were set: to analyze literary sources to reveal the topic of conscious consumption; to study the general world trends of conscious consumption in the category of clothing – from the point of view regarding how does phenomenon of conscious consumption is disseminated, and regarding to dissemination of information about this fact; to conduct a qualitative survey of a representative sample of consumers for their behavior in the field of fashion industry products consumption; to draw conclusions about the state and prospects of conscious fashion in the domestic market. The study of literature sources and approaches to solving the problem of the detrimental impact of the fashion industry, in particular the fast fashion sector, showed the need to promote this problem and the insufficient awareness of Ukrainians in conscious consumption field. The urgency of solving this scientific problem is that the purchasing behavior and habits of Ukrainians in the field of goods of the fashion industry is somewhat different from the behavior of European consumers, which is due to the impact of the hard trade deficit during the Soviet Union times. To achieve the goals of the article, normative documents of both international level and internally adapted materials were processed. Empirical methods have been used to describe the general problems of the harmful impact of the fashion industry on the environment and approaches to its solution. The own marketing sociological survey about the conscious consumption of fashion industry goods by Ukrainians was conducted using digital tools. Theoretical research methods such as analysis, generalization, explanation and classification are used. The results of the study may be valuable for top managers of domestic and international fashion companies in restructuring their business strategy and marketing strategy to a more environmentally and socially oriented – respondents demonstrated a willingness to pay more for recycled clothing and willingness to properly dispose of clothing – and these are, in fact, specific recommendations for the development of new collections and ideas for new environmental programs and communication plans. Thus, the willingness of consumers to practice environmental approaches in consumer behavior confirms the need to promote this study among the public and stakeholders in order to raise awareness in the conscious consumption field.

In order to improve the cruising range of new energy electric vehicles and solve the low efficiency of electric transmission system in low-speed driving stage, a space vector pulse width modulation algorithm is proposed. The simulation model is established by Matlab/Simulink software, and the test parameters of electric transmission system in the actual driving process of new energy electric vehicle are analyzed, and the harmonic distribution of line voltage of electric transmission system and the influence of battery bus voltage on harmonic content are explored. The actual test results show that reducing the difference between the bus voltage and the fundamental line voltage under actual electric transmission can reduce the harmonic content and improve the system efficiency. According to the characteristics of power generation system, a reliable motor optimization scheme is proposed to reduce harmonic content to improve the efficiency of electric transmission system of new energy vehicles.
