“…On the other hand, Kahia et al (2016) proposed that most renewable energy technologies might be less competitive than non-renewable energy due to a high level of initial capital cost and thus higher levelized cost of electricity. This explains the competitive disadvantage of renewable energy due to lengthy payback time needed to recover high initial capital costs (Baulch et al, 2018). This speedy decline of the costs of renewable energy technologies is mainly attributed to substantial advances and manufacturing capacities.…”

“…However, 2015 was the first year when investment in non-hydro renewables was higher in developing countries than advanced countries, with investments reaching US$156 billion, mainly in China, India, and Brazil (FS-UNEP Collaborating Centre, 2016). The technical potential for renewable energy in the developing world is enormous (see Baulch et al (2018) for Vietnam). Many developing countries have abundant renewable energy resources, such as biomass, geothermal energy, solar energy, and wind power, as well as the ability to manufacture the relatively labor-intensive systems that harness these energy sources (Flavin and Aeck, 2010).…”

This study aims to reexamine how energy consumption interacts with economic growth and emissions using a panel data of a global sample consisting of 102 countries, from 1996 to 2012. The effects of renewable energy and nonrenewable energy sources are separately examined. The consumption of both renewable and nonrenewable energy appears to have contributed significantly to the level of income across countries, implying that promoting renewable energy benefits economic development. The empirical evidence suggests that the use of non-renewable energy consumption significantly raised the level of emissions across different income groups of countries. On the other hand, our findings suggest that the use of renewable energy sources helped tackle emissions in developed countries but not in developing countries. The success of developed countries in controlling emissions through renewable energy has significant policy implications for developing countries.

“…With the rapid development of the economy, along with the process of industrialization, modernization and population growth, the demand for electricity use in Vietnam is rocketing. Whereas, in recent years, that demand has increased by 12% to 16% per year [1,2]. The intensity of energy consumption in Vietnam is among the highest in the region and around the world.…”

In the context of dramatically increase in electricity demand, Vietnam's potential for power supply remains limited. Research and promotion of electricity saving behavior of households become significant to reduce electricity consumption and protect ecological environment. This study incorporates elements of planned behavior theory (TPB) and norm activation model (NAM) as the basis for developing and extending key assumptions. In addition, expansion TPB is used to study influence factors affecting electricity saving behavior. Through a sample of 395 randomly selected residents in Tay Ninh Province and Ho Chi Minh city in Vietnam, the proposals were checked using a structural equation model (SEM). The results showed that the factors in TPB and NAM (such as perceived behavioral control, subjective norm, attitude, personal moral norm) and additional factor (perceived benefit) are the important factors that influence resident's intention of saving electricity. Moreover, electricity saving behavior is strongly influenced by the intention of saving electricity, perceived benefit, policy and social propaganda. Based on these results, some inferences are drawn, and recommendations are made for policy makers and further research proposals are discussed.

“…Thus, before applying the solar tracking system in any region, an intensive investigation should be carried out. To our knowledge, an extensive investigation into the fabrication and operation of solar tracking systems in Vietnam and other Association of Southeast Asian Nations (ASEAN) has been rarely reported [33,34]. To understand the energy gain by the solar tracking system globally, an extensive study in a large area and countries is very important.…”

Recently, the demand for small grid-connected photovoltaic (PV) systems has been rapidly increasing; this is due to the reduction in the costs of grid-connected storage systems as compared to those of the stand-alone ones. Notably, the performance of the solar tracking system is not only depending on the types but also the region that they are set up and used. To understand how solar tracking systems work globally, we need to know their performance in each country and even the different parts of a country. In this study, two grid-connected PV systems with 250 W solar modules were used to investigate the efficient improvement of a single-axis sun tracking system in Central Vietnam. First, a mechanical tracking device with a linear actuator and a controller was designed and then its performance was comprehensively investigated with a grid-connected PV system. In addition to evaluating the energy gain by the tracking system, this study also considered the energy consumption of the linear actuator with its controller and a small grid-connected PV system; this has generally been omitted in previous works. Experimental results indicate that the total energy consumption of the tracking system was approximately 2–8% of the energy generated by the grid-connected PV system. The maximum overall energy generation was confirmed to have increased by up to 30.3% on a sunny day upon using the proposed tracking system; further, the net energy gain by using the sun tracker was ascertained to be 15.2% in average weather conditions. Based on the success of this work, we will keep experimenting with other parts of Vietnam. Also, we will collaborate with colleagues in other countries to create a guideline for understanding and using the solar tracker regionally and globally.
