This study aims at evaluating the green growth in Vietnam in terms of energy consumption and CO2 emission level using the theory of the relationship between economy and environment. Data of Vietnam’s energy consumption and CO2 emission level in the period of 1985-2014 are obtained from the World Bank. Results show that the fossilized energy consumption to the total energy consumption ratio sharply increased from 29.57% in 1985 to 71.05% in 2011. The CO2 emission level also experienced a strong rise, from 0.3595 ton per capita in 1985 to 1.7281 ton per capita in 2010. On average, the CO2 emission per capita is 0.74 tons during this period. In addition, there is also a clear relationship between GDP per capita and CO2 emission level in the period with an explanation capacity of 95.2%. The study also offers some suggestions to the green growth policy in Vietnam for the next period.

Energy consumption is increasing due to the expansion of economic activity and population size which results higher GHG emission worldwide. The study has examined the trends of energy consumption and CO2 emission in Bangladesh using the secondary data extracted from the World Development Indicators of the World Bank database. The results found that there is an increasing trend of total energy consumption and per capita energy consumption in Bangladesh from 1991 to 2012 where the total energy consumption has been increased nearly three times from 12.55 mtoe (million tonne oil equivalent) in 1991 to 33.17 mtoe in 2012. The total CO2 emission was estimated by 57.07 mtoe in 2011 which was increased by 140.67% compared to the 1991 emission of 15.94 mtoe. Thus, the CO2 emission and per capita emission has also provided increasing trend over the period of 1991 to 2011.It has revealed that the growth of CO2 emission found to be higher than the growth of GDP and energy consumption in Bangladesh. The yearly average growth of CO2 emission has estimated by 6.7% which is higher that the annual average growth of GDP and energy consumption as of 5.25% and 4.77% respectively. This situation calls for serious attention of the country for reducing CO2 emission. Therefore, government needs to develop a national mitigation plan/policy and promote the use and development of green technology, renewable energy and green growth for sustainable energy and environment in Bangladesh.

As a new type of underwater observation platform, underwater glider is widely used in marine explorations and military surveys, and most gliders are powered by their own batteries whose capacities are limited. It is therefore necessary to analyze the energy consumption of underwater glider. In this article, the variation law of seawater density changing with depth is considered; based on the theory of rigid body dynamics, the motion model of blended-wing-body underwater glider is established; the energy consumption model of each component module is accounted by analyzing the energy consumption composition in the working process of blended-wing-body underwater glider; and the energy consumption under different navigation depths, different glide ratios, and different buoyancy adjustments regulation is simulated. The results demonstrate that as the glide depth is increased, the total energy consumption increases in a single cycle and decreases per gliding distance, leading to a smaller energy consumption ratio for the attitude adjustment module; on the other hand, as the buoyancy adjustment is increased, more energy is consumed in a single cycle and less energy is consumed per gliding distanced, resulting in a larger energy consumption ratio for the attitude adjustment module. As the glide ratio increases, the total energy consumption in a single cycle first increases and then decreases, while the energy consumption of per gliding distance and the energy consumption ratio of the attitude adjustment module are decreased.

Recognizing the change in regulation of energy consumption may help China to control total energy consumption and realize sustainable development during rapid urbanization and industrialization. This paper re-examined the trans-provincial convergence of per capita energy consumption from 1990–2015 using five different kinds of methods for 30 Chinese provinces. Results show that per capita energy consumption across Chinese provinces was convergent. However, the results obtained by different methods were slightly different. First, it shows a weak beta-unconditional convergence during the entire period, as well as a significant beta-unconditional and conditional piecewise convergence from 1990–2000 and 2001–2015. Second, it shows a significant sigma-convergence indicated by a marked decrease in the standard deviation of logarithm (SDlog) and the coefficient of variation (CV). Third, the kernel density curve became narrower during 1990–2015, indicating that the per capita energy consumption of each Chinese province converged to a common equilibrium level, which was about 80% of the national average. Fourth, the intra-distributional mobility index implied a weak gamma-convergence. Fifth, the first difference of DF (Dickey-Fuller), ADF (Augmented Dickey-Fuller), and PP (Phillips-Perron) unit-root tests all suggested a stochastic convergence. On the whole, the results from this paper contribute to a more in-depth understanding of the status quo of per capita energy consumption in China, as well as a meaningful implication for differentiated energy policies and sustainable development strategies.

The Relationship

In China, transportation accounts for a large proportion of total energy consumption and that trend is projected to increase in the future. Through the stochastic impacts by regression on population, affluence, and technology (STIRPAT) model, OLS regressions were conducted to investigate the impacts of gross domestic product (GDP), urbanization, energy intensity and transport structure on the transport energy consumption in China’s three regions. The analyses of inter-provincial panel data during the period 2006–2015 is compared to the analysis of the data from 1996 to 2005 to determine the change. There were two primary findings from this study. First, the changes of the influencing degree in three regions are considered. GDP is still the main driver of transport energy consumption in eastern region, while urbanization becomes the main driver in the other two regions. Second, the relationship between the elasticity and the value of each variable is detected. The elasticity of transport energy consumption with respect to GDP, transport structure, energy intensity and urbanization have separate positive and significant relationships. The primary measure is to optimize transport structure in the central region, while reducing energy intensity in the western region. Finally, we propose relevant policy recommendations for the three regions.
