Vietnam’s economy has been growing rapidly in the last 20 years, leading to significant increases in energy consumption as well as in carbon emissions. Most electricity is consumed by loads of industry and construction due to the country’s socio-economic development strategy. An energy saving strategy cannot be achieved if the industry factories lack energy consumption data. The installation of energy monitoring systems can help to improve energy efficiency by supplying daily, monthly, and yearly energy consumption reports. Moreover, major energy-consuming enterprises in Vietnam must implement solutions for energy-efficient use as prescribed in the Law on Energy Efficient Use. Therefore, this study aimed to determine the impact of an energy monitoring system as an improvement solution for energy efficiency in a typical major energy-consuming enterprise in Vietnam. The study’s results, after six months, show that the total saved electricity after installing the power monitoring system was 191,923 kWh. The company saved approximately 19.584 USD and reduced emission to the environment by 139 tons of CO₂. In addition, the return on investment time of power monitoring systems is about 14 months, while the annual energy costs of the factory can be reduced by about 9.62% per year. Therefore, power monitoring systems should be promoted in factories with different scales to control energy wastage in the domestic industry field.

In this paper, blister formation on a lined fluoropolymer-steel substrate’s exposure to water and hydrochloride acid solution at different temperatures and temperature gradients was studied. The higher the temperature gradient between the lining and the substrate, the faster the blister will form. In the absence of a temperature gradient, the temperature also affects the formation of blisters. The higher the working environment temperature, the faster the blistering will appear. Even so, the role of temperature gradients in promoting blistering is far greater than that of temperature. The concentration of HCl solution also affects the formation of blisters. Blistering occurs more slowly in high-concentration solutions and water is determined to be the main cause of blister formation.

Purpose: This study aims to present the factors affecting and comparing the difference in community acceptance between groups of survey from the perspective of behavioral reasoning theory (BRT).Design/methodology/approach: This study presents a quantitative method through conducting survey of 152 local residents from three provinces of Viet Nam.Findings: This study examines the new approach of “reason for” and “reason against” community acceptance within the context of wind energy development in Viet Nam. This study also suggests that “reason for” have a positive impact on the local community; however, issues like noise and shadow cast by turbine blades are significant challenges that contribute to the “reason against” acceptance. This study’s findings provide evidence of the importance of location and socio – economic impacts in influencing community acceptance and can give some feedback for local policymakers in Viet Nam’s energy sector as they implement wind projects in potential areas.Originality/value: To the best of the author's knowledge, this study is the first empirical study conducted across three Vietnamese provinces on community acceptance of onshore wind energy. The integration of literature on socio-acceptance with BRT in energy research contributes valuable insights to the fields of energy behavior and energy policy research.
