基于电力结构调整的上海市电力行业大气污染物排放总量研究

基于上海市能源与电力统计数据,参考政府间气候变化专门委员会(IPCC)及国内发电企业污染物排放相关研究报告,设定不同发电方式的装机比例,分析核算不同装机比例下SO2、NOX以及CO2的排放量与减排量。结果表明,装机比例提升10.0%,相比煤电装机,天然气装机的SO2、NOX及CO2的排放量分别降低90.2%、91.3%与99.9%,减排效果显著。新能源装机比例由5.0%提升至10.0%,SO2、NOX及CO2分别削减3.0×103、3.8×103、3.6×107 t。     

CHEAP POWER - AN EXPENSIVE FAILURE: HYDRO-ELECTRIC POWER AND INDUSTRIAL DEVELOPMENT IN NEWFOUNDLAND1

ABSTRACT By creating the 459,000 kW Bay d'Espoir h.e.p. scheme, the Newfoundland government hoped that the consequent doubling of the island's electricity supply would not only eliminate a deficite situation but provide power for industrial development. These hopes have not been fulfilled, and only one company, producing elemental phosphorus, was attracted to the island by the government's ‘cheap power’ policy. In addition to the continuing power subidy, this company received considerable federal and provincial incentives by locating its plant in Newfoundland. To these direct financial costs have to be added the environmental destruction and deterioration stemming from the h.e.p. development and the haste with which its construction was undertaken, and the catastrophic pollution problem created by effluent from the phosphorus plant. The costs of the ‘cheap power’ policy have been, and continue to be, massive for Newfoundland, Canada's poorest province. Further, the policy has made little or no impact on the small job market and the very large unemployment problem.     

Electricity consumption and economic growth nexus in Zimbabwe revisited: fresh evidence from Maki cointegration

This study explores the relationship between electricity consumption, real gross domestic product per capita and carbon dioxide emissions in Zimbabwe. To achieve this, the study set off by examining the stationarity properties of the variables under review with the Zivot-Andrews (1992 Zivot, E., and D.W.K. Andrews. 1992. Further evidence on the great crash, the oil-price shock, and the unit-root hypothesis. Journal Of Business and Economic Statistics 10:251-270. doi: http://dx.doi.org/10.2307/1391541.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) unit root test that accounts for a single structural break. Subsequently, Maki (2012 Maki, Daiki. 2012. “Tests for Cointegration Allowing for an Unknown Number of Breaks.” Economic Modelling 29 (5): 2011–15. https://doi.org/10.1016/J.ECONMOD.2012.04.022 [Google Scholar]) cointegration test, which accounts for multiple structural breaks, is applied for equilibrium relationship between the variables under review while the long run regression of dynamic ordinary least square (DOLS) is employed for long-run coefficients as estimation procedures. In order to account for the direction of causality flow, the Toda-Yamamoto (1995 Toda, H Y.., and Taku Yamamoto. 1995. Statistical inference in vector autoregressions with possibly integrated processes. Journal Of Econometrics 66 (1–2):225–50. doi: 10.1016/0304-4076(94)01616-8.[Crossref], [Web of Science ®] , [Google Scholar]) causality test is used for annual frequency data set spanning from 1971–2014. Empirical evidence from the Maki cointegration test shows that there exists a long-run equilibrium relationship between electricity consumption, carbon dioxide emissions and real gross domestic product per capita over the sampled period. The long-run regression suggests that there exist a positive statistically significant relationship between real income and electricity consumption. Thus, corroborating the electricity-led growth hypothesis. This result is supported by the causality test, as one-way causality is observed running from electricity consumption to real gross domestic product. Thus, this is suggestive to government administrators and policymakers that the Zimbabwean economy is electricity dependent. However, there is a tradeoff for environmental quality. As the increase in electricity consumption increases carbon dioxide emissions. The need for diversification of Zimbabwe energy portfolio to cleaner and environmentally friendly energy sources is recommended, given the world global consciousness for cleaner energy consumption.

REVIVING URBAN STREAMS: LAND USE,HYDROLOGY, BIOLOGY,AND HUMAN BEHAVIOR1

ABSTRACT: Successful stream rehabilitation requires a shift from narrow analysis and management to integrated understanding of the links between human actions and changing river health. At study sites in the Puget Sound lowlands of western Washington State, landscape, hydrological, and biological conditions were evaluated for streams flowing through watersheds with varying levels of urban development. At all spatial scales, stream biological condition measured by the benthic index of biological integrity (B‐IBI) declined as impervious area increased. Impervious area alone, however, is a flawed surrogate of river health. Hydrologic metrics that reflect chronic altered streamflows, for example, provide a direct mechanistic link between the changes associated with urban development and declines in stream biological condition. These measures provide a more sensitive understanding of stream basin response to urban development than do treatment of each increment of impervious area equally. Land use in residential backyards adjacent to streams also heavily influences stream condition. Successful stream rehabilitation thus requires coordinated diagnosis of the causes of degradation and integrative management to treat the range of ecological stressors within each urban area, and it depends on remedies appropriate at scales from backyards to regional storm water systems.     

STORMWATER DETENTION BASINS AND RESIDENTIAL LOCATIONAL DECISIONS1

ABSTRACT: Residents of seven subdivisions with wet and dry stormwater basins were questioned about the role the basin played in their decision to purchase their home. They were asked to estimate the impact of such basins on the image of residential developments and on lot values. Respondents believed that wet basins contributed positively to subdivision image and that lots in developments with wet basins were more valuable than comparable lots in dry basin subdivisions. Lots adjacent to wet basins were perceived as the most valuable, while those adjacent to dry basins were considered the least valuable.
