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。 相似文献

CHEAP POWER - AN EXPENSIVE FAILURE: HYDRO-ELECTRIC POWER AND INDUSTRIAL DEVELOPMENT IN NEWFOUNDLAND1
Peter Crabb 《Journal of the American Water Resources Association》1974,10(1):42-53
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. 相似文献

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) unit root test that accounts for a single structural break. Subsequently, Maki (2012) 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) 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. 相似文献

通过静态模拟实验,分析了外秦淮河底泥中释放出的与黑臭有关的DO、COD、NH3-N对上覆水水质的影响。上覆水中COD质量浓度是前4d呈下降趋势,至第11d基本稳定;NH3-N质量浓度是前4d呈上升趋势,至第11d趋于稳定;DO质量浓度是从开始实验时的7mg/L左右,很快下降至第11d的1mg/L以下才基本稳定。结果表明,外秦淮河底泥释放对上覆水水质有一定影响,并且这种释放有明显的梯度效应。 相似文献

The health care staff operating magnetic resonance imaging (MRI) scanners are exposed to static magnetic field of significant
spatial heterogenity and high level of flux density—usually existing permanently during the shift. The personnel can also
be exposed to pulses of magnetic field of high rate of rise/fall, so-called gradient fields, which exist only during examination
of patients. The level of workers’ exposure depends both on the type of the magnet and on the ergonomical characteristic of
design of the particular MRI scanner. This paper presents the current state of the art on occupational exposure to static
magnetic field health effects, gaps in scientific data, MRI workers’ exposure characteristics, research needs, and suggestions
for the exposure assessment protocol for future investigations. 相似文献
