Fuel Consumption And Emissions

Many challenges are associated with the ever increasing level of energy consumption and the damage to the environment caused by the pollutants from all sectors, On the local level the problem is associated with matters such as noise and air pollution, while on the global level the problems are associated with acid rain, ozone layer depletion and the greenhouse effect (global warming). The transport sector is a major contributor in this respect. The use of appropriate decision-making tools to assist in the assessment of alternative transport policies is required urgently. One such tool is the TEMIS program which was described in Part 1 of this investigation, where the methodology for the enhancement of TEMIS was reported. The enhanced version of TEMIS has subsequently been used to model the effects of different transport scenarios in order to improve future fuel economy and the adverse effects of air emissions as well as the greenhouse gases. In the present paper, three main case studies have been considered to test the effect of different scenarios (in terms of alternative fuels and technical advances) on energy consumption and emissions: firstly, the switch to alternative fuels, through investigating the effects of switching from petrol to diesel, secondly, the effects of switching from diesel to bio-diesel (for buses) and, finally, the effects of technical advances (three-way catalytic converters) and the effects on fuel consumption and emissions are considered.

The National Energy Policy and Conservation Act of 1978 requires the Federal Trade Commission to mandate labels for appliances indicating their energy consumption. The purposes of this study are to measure the level of awareness of appliance energy labels by recent purchasers of refrigerators and washers, and to measure changes in the degree to which energy considerations entered into the purchase decisions of national samples of consumers before and after introduction of the FTC program.

Controlling energy consumption to reduce greenhouse gas emissions has become a global consensus in response to the challenge of climate change. Most studies have focused on energy consumption control in a single region; however, high-resolution analysis of energy consumption and personalized energy policy-making, for multiple regions with differentiated development, have become a complicated challenge. Using the logarithmic mean Divisia index I (LMDI) decomposition method based on energy allocation analysis (EAA), this paper aims to establish a standard paradigm for a high-resolution analysis of multi-regional energy consumption and provide suggestions for energy policy-making, taking 29 provinces of China as the sample. The process involved three steps: (1) determination of regional priorities of energy consumption control by EAA, (2) revealing regional disparity among the driving forces of energy consumption growth by LMDI, and (3) deriving policy implications by comparing the obtained results with existing policies. The results indicated that 29 provinces can be divided into four groups, with different priorities of energy consumption control according to the patterns of coal flows. Most provinces have increasing levels of energy consumption, driven by increasing per capita GDP and improving living standards, while its growth is restrained by decreasing end-use energy intensity, improving energy supply efficiency, and optimization of industrial structures. However, some provinces are not following these trends to the same degree. This indicates that policy-makers must pay more attention to the different driving mechanisms of energy consumption growth among provinces.

The worldwide consumption of fossil hydrocarbons in the road transport sector in 2020 corresponded to roughly half of the overall consumption. However, biofuels have been discreetly contributing to mitigate gaseous emissions and participating in sustainable development, and thus leading to the extending of the commercial utilization of internal combustion engines. In this scenario, the present work aims at exploring the effects of alternative fuels containing a blend of 15% ethanol and 35% biodiesel with a 50% fossil diesel (E15D50B35) or 50% Fischer–Tropsch (F-T) diesel (E15FTD50B35) on the engine combustion, exhaust emissions (CO, HC, and NOx), particulate emissions characteristics as well as the performance of an aftertreatment system of a common rail diesel engine. It was found that one of the blends (E15FTD50B35) showed more than 30% reduction in PM concentration number, more than 25% reduction in mean particle size, and more than 85% reduction in total PM mass with respect to conventional diesel fuel. Additionally, it was found that the E15FTD50B35 blend reduces gaseous emissions of total hydrocarbons (THC) by more than 25% and NO by 3.8%. The oxidation catalyst was effective in carbonaceous emissions reduction, despite the catalyst light-off being slightly delayed in comparison to diesel fuel blends.

Hydropower (HP) in Europe is playing an increasingly important role. Its share in final energy consumption varies from country to country, which is associated with different challenges for each of them. This article presents the challenges of HP development in three countries with a diversified domestic share, i.e., Albania (100% share in 2019), Slovenia (25.7%) and Estonia (0.3%). Particular attention was paid to issues of rational management of water resources in conjunction with the objectives of nature protection and European energy policy. As a result of the analysis, the following challenges in the development of HP were identified: the need to modernize the current HP network, conflicts related to the implementation of HP projects in naturally valuable areas, dependence on external electricity supply due to adverse environmental conditions, problems with the diversification of energy sources and lack of cooperation between environments representing different interests. The countries described have different local specificities; therefore, the challenges in the development of HP are different in each of them. The key to solving them is especially mutual cooperation between various environments, integration of energy markets and diversification of used energy sources, with an indication of renewable energy sources (RES). This will enable harmonious development of each country. Furthermore, it cannot be clearly determined whether the assumed objectives of EU energy policy will be achieved. Achieving these goals is possible because the share of RES in final energy consumption in the countries described is growing.

Alternative Energy Sources

In urban areas, the transport sector is one of the main sources of significant energy consumption and carbon emissions. Although diesel and gasoline are still the main sources of energy used in urban transport, more and more attention is now being paid to alternative and transitional sources of energy, as they are renewable and have less negative impact on the environment. However, the successful use of alternative energy sources can be hindered by various technical, economic and political factors. This article discusses the latest literature on alternative and transitional energy sources in order to understand the possibility of their use in urban transport at present, as well as the possibility of introducing these sources in the future
