A Study on Future Energy Consumption and Carbon Emissions of China’s Transportation Sector  [PDF]
Hailin Wang, Xi Yang, Xunmin Ou
Low Carbon Economy (LCE) , 2014, DOI: 10.4236/lce.2014.54014
Abstract: The actual energy consumption of China’s transportation sector accounts for 10% - 15% of the nation’s total energy consumption. Experience from developed countries shows that on entering a phase of stable urbanization, transportation will account for around 30% of total energy consumption, close to levels seen in developed nations (nearly 40%). Transportation in China is one of the sectors with the fastest growth in energy consumption. A literature review shows an obvious future growth in China’s total energy usage within this sector, with a continuous increase from baseline until 2050. However, withstrict policy the growth will drop a little by 2030, but will still be about 1.5 times higher than current levels (reported in 2010) in 2050. Therefore, China needs to further optimize traffic infrastructure, properly allocate resources, and improve transportation technology and energy efficiency. This will help realise infrastructural energy saving and facilitate China’s low-carbon transportation sector development.

Energy and Power Engineering (EPE) , 2015, DOI: 10.4236/epe.2015.73009
Abstract: In this paper, we present an analysis of energy and exergy utilization in the residential sector of Cameroon by considering the sectoral energy and exergy flows for the years of 2001-2010. Exergy analysis of Cameroon residential sector utilisation indicates a less efficient picture than that obtained by the energy analysis. Cooking stands out as the most inefficient end use in the Cameroon’s residential sector. In 2010, the energy and exergy efficiency are determined and were respectively 58.74% and 22.63%. Energy and exergy flows diagrams for the overall efficiencies of Cameroon residential sector are illustrated and a comparison with the residential sector of other countries is also done. To carry out this study, a survey of 250 households was conducted and the sharing of the end uses of energy was done and data were gathered.

Green Transport Infrastructure of Taiwan  [PDF]
Shyi-Min Lu, Ching Lu, Yu-Shun Huang
Open Journal of Energy Efficiency (OJEE) , 2013, DOI: 10.4236/ojee.2013.21003
Abstract: Transport is the lifeblood of a nation’s economy. Since the fossil fuels are being gradually depleted and the global warming phenomena are more and more serious, this article is to construct a low-carbon transport infrastructure for Taiwan by the implementation of energy-saving measures. First of all, via data collection and analysis, we found that the small passenger cars and the large trucks are the largest energy users in the transport sector, due to their high energy intensities and large transport volumes. Therefore, their energy-conserving potentials are the focuses of this study. According to “Top-Down” methodology, the most effective and economical energy-saving strategies for Taiwan’s transport sector are the significant adoptions of rail transport and electrification mode. Whereby, under a maximal energy-saving scenario, comprising of delicate shift of transport volumes, the energy saving potential in the land transport sector of Taiwan is 4914 MLOE (million liters of oil equivalent), which is equivalent to greenhouse gas reduction of 10.56Mt-CO2e approximately with a scale of 45.3% or crediting for 4.1% reduction of national GHG emissions. Finally, we suggest the green transport infrastructure of Taiwan should be mainly comprised of rail transport, electric motorcycles, MRT (Mass Rapid Transit), and EV (Electric Vehicles).
Integrating Renewable Energy and Smart Grid Technology into the Nigerian Electricity Grid System  [PDF]
Emodi Nnaemeka Vincent, Samson D. Yusuf
Smart Grid and Renewable Energy (SGRE) , 2014, DOI: 10.4236/sgre.2014.59021
Abstract: The electricity situation in Nigeria can be described as epileptic with no sign in view of improvement. This epileptic power situation affects the manufacturing, service and residential sectors of the economy which in turn affects the country’s economic growth. Even with the recent reforms in the power sector, more than half of the country’s population still lack access to electricity. The epileptic condition of the power sector can be attributed to the inadequate and inefficient power plants, poor transmission and distribution facilities, and outdated metering system used by electricity consumers. This paper attempts to present the way forward for the Nigerian poor electricity situation by reviewing the power sector as a whole and the renewable energy potentials. We identified the problems in the national grid and then proposed a smart grid model for the Nigerian power sector which will include renewable energy source. We believe that the content of this review paper will solve the poor epileptic condition of the power sector in Nigeria and also enable the proper integration of smart grid technology into the national grid.
Anticipated Actions to Reduce Energy Shortages in the Residential Sector  [PDF]

Abstract: This study investigates the electric energy shortages impact upon the residential sector in Riyadh city, the capital of the Kingdom of Saudi Arabia (KSA) resulting from severe power outages. The results reveal the extent of hardship and high costs the residential will suffer and endure. These outages occur and extend for longer durations. To mitigate these consequences, a method is suggested known as “willingness-to-pay” to seek the ability and willingness of consumers to pay to avert these power outages and energy shortages. Two approaches have been developed and utilized. The first one is based on a consumer survey to estimate his perceived costs. Outages occur in specific periods and last for longer durations. The second approach focussed on developing a mathematical model to complement the survey approach as this model can decrease the size of the problem complexity associated with consumer lack of experience in evaluating and assessing the worth of service reliability and quality.

Abstract: This study, discuss the stability problem of Resha generation plant. The length of the transmission line which connect Resha with Haranah station, decrease the power transferred capacity that increase the risk of transient disturbance on the system, especially when the generators loaded at full load. Beside that several solutions were suggest in order to improve system stability and raise the capacity of transmitted power.
Analysis on electrical energy consumption of agricultural sector in indian context
K. V. S. Ramachandra Murthy,M. Ramalinga Raju
Journal of Engineering and Applied Sciences , 2009,
Abstract: This paper attempts to identify inter-linkages between agriculture and Electricity. The growth of agriculture has been possible because of timely and adequate supply of water. As a result, ground water irrigation started assuming greater importance as compared to canal irrigation. Farmers have better control over water availability with ground water irrigation. A study of Electrical Energy requirements for the irrigation purposes based on crop pattern and area irrigated under various heads has been carried out. The energy audit reports of various departments such as Irrigation, Agriculture and Electric Utilities are some time at variance. This paper highlights the need for proper interfacing between these agencies to evolve a credible strategy for optimum utilization of resources like electrical energy and underground water.

International Journal of Energy and Environment , 2011,
Abstract: Nowadays, Serbia needs to disengage from the broad use of fossil fuels and turn to the “attractive” Renewable Energy Sources (RES) for energy production, since the Kyoto Protocol ratification, so as to resolve systematically the problem of energy demand. In addition, research indicates that Serbia is a country with high potential and favourable conditions for RES energy production, as the country’s potential could supply almost half of its primary energy needs. The paper provides an overview of Serbia’s energy sector status quo, so as to emphasize the necessity for RES implementation in order to balance the country’s energy deficit. The aim is to investigate and present the country’s prospects in the RES sector, revealing the proven RES potential and pointing out that the unexploited RES potential together with an adequately well structured energy sector would create great possibilities and conditions for a new market.

Mahmoud S. Awad,Anwar Al-Mofleh
Journal of Emerging Trends in Computing and Information Sciences , 2012,
Abstract: This paper examines building energy efficiency parameter in order to improve efficient of construction projects as well as looking into making the building more energy efficient. Buildings considered one of the largest consumers of energy. In the developing countries huge number of new buildings is constructed yearly. One of the major barriers for better building energy efficiency is the lack of aiding tools during the primary design stage. A major barrier during design process of building has been the difficulty in finding the available suitable programs. ENERGY-10 overcomes this hurdle by automating many of the time-consuming tasks, shortening the time required from hours or days to minutes. Buildings descriptions are created automatically based on defaults
