Sources of renewable energy have received wide attention in the literature because of serious threats to the environment. However, some renewable resources, including biomass energy role is debatable in the energy economics literature. This empirical work focuses to analyze the role of biomass energy in carbon dioxide (CO2) emissions using the framework of the environmental Kuznets curve (EKC) in Pakistan over the period from 1980 to 2015. The bound testing approach suggests there is cointegration among study variables. The study uses an auto-regressive distributed lag model (ARDL) with a structural break in the series. To summarize the findings of the study, it can be inferred that biomass energy increase CO2 emissions. In addition, biomass energy helps to form a U-shaped relationship between income and CO2 emissions that support the EKC hypothesis. Also, the feedback hypothesis is found between biomass energy and CO2 emissions. The findings would guide policymaker with practical guidelines to formulate policies to utilize a high amount of biomass energy in a sustainable manner.

Municipal and state regulations limiting the allowable sulfur content of fossil fuels are having the effect of changing fuel use patterns of many of the nation’s utilities. The utility companies are faced with increased costs of lower sulfur fuels and capital expenditures associated with the fuel changes, as well as with greater uncertainty concerning long term supplies of suitable fuels. Capital costs for air pollution control are mounting. Electrostatic precipitators must be built to meet more stringent air pollution codes, and stack heights may have to be increased to improve discharge patterns. Other capital expenditures for added requirements such as steam and electric tracing and pumping equipment must be made to accommodate distinctive characteristics of low sulfur fuels. Air pollution control costs do not result in increased productivity, improved products, or products that will command a better price in the market. Nevertheless, the expenditures are essential. Nuclear power is the long range solution to which many utilities look but, in the shorter view, the power industry must expect continued cost increases in the areas of fuel and operating expenses, capital expenditures and research and development.  相似文献

This paper presents an energy and environmental network analysis model to explore tradeoffs associated with freight transport. The geospatial model uses an intermodal network built by the authors to connect various modes (rail, road, water) via intermodal terminals. Routes along the network are characterized not only by temporal and distance attributes, but also by cost, energy, and emissions attributes (including emissions of carbon dioxide, particulate matter, sulfur oxides, volatile organic compounds, and oxides of nitrogen). Decision-makers can use the model to explore tradeoffs among alternative route selection across different modal combinations, and to identify optimal routes for objectives that feature energy and environmental parameters (e.g., minimize carbon dioxide emissions). The model is demonstrated with three case studies of freight transport along the U.S. eastern seaboard.  相似文献

This study examines the relation between CO2 emissions, income, non-renewable, and renewable energy consumption in Algeria during the period extending from 1980 to 2011. Our work gives particular attention to the validity of environmental Kuznets curve (EKC) hypothesis. The autoregressive distributed lag (ARDL) with break point method outcome demonstrates the positive effect of non-renewable type of energy on CO2 emissions consumption. On the contrary, the results reveal an insignificant effect of renewable energy on environment improvement. Moreover, the results accept the existence of EKC hypothesis but the highest gross domestic product value in logarithm scale of our data is inferior to the estimated turning point. Consequently, policy-makers in Algeria should expand the ratio of renewable energy and should decrease the quota of non-renewable energy consumption.  相似文献

Marine algae have made a strong contribution to global food security in the future. This study is the first report describing the concentration, pathways, and interactions of halogens in 15 species of marine algae collected from the Eastern Harbor in Alexandria, Egypt, relative to 22 key variables. The relationship between halogen content and chemical and biochemical parameters was studied through multivariate analysis. Among all the tested algae, the iodine content was the lowest (2.53–3.00 μg/g). The range of fluoride and chloride in macroalgae (1.12–1.70 and 0.10–0.46 mg/g) was smaller than that of microalgae (0.10–0.46 and 1.48–3.17 mg/g). The bromide content in macroalgae (0.36–5.45 mg/g) was higher than that in microalgae (0.40–0.76 mg/g). The halogen content in macroalgae was arranged in the order of Br > F > Cl > I. In addition, the biochemical parameters such as carbohydrates, proteins, lipids, and certain heavy metals (Fe, Zn, Cu, Mn, Pb, Ni, Co, Cd, and Cr) were determined. Calories, energy, total antioxidant activity (TAC), K/Na, and ion quotient amounts were estimated. The results showed that the green seaweed species had the highest TAC content. In most of the studied algal species, the calculated ion quotient referred to their likelihood of overcoming high blood pressure. The estimated daily intake (EDI) of algae showed no adverse effects on human health. Most of the research variables are below the acceptable WHO/FAO level. Generally, the calorie content of the selected algae is less than 2 kcal, which makes the algae considered an alternative source of healthy food to reduce obesity.
