This research examines the impact of increasing the stringency of renewable portfolio standards (RPS) on the consumption of energy produced from renewable sources. Putting prior findings in the context of policy learning, first we focus on technological innovation, factor endowments, and economic energy dependence of American states to track how RPS have proliferated and strengthened. Next, we look at the net effect of this RPS evolution on state fossil fuel energy divestment. To evaluate the interplay between: a) the political desire to lower fossil fuel use, b) technological feasibility to do so, and c) the economic trade‐offs and risks, we focus on the industrial sector dependence on energy security and affordability. Our results indicate that energy security is a priority and even in light of increasing RPS stringency, states with relatively weak but mandatory RPS are leaders in aggregate renewable energy consumption. This fact is due to favoring biofuel and hydro generation rather than solar and wind because of lower deployment costs.  相似文献

Innovation is the central element of climate change policy in many jurisdictions. Reduced to technology development and linked to market‐driven priorities, innovation accommodates the interests of large emitters in the energy sector and underpins a sustainable development discourse that denies ecological limits to economic growth. This study examines the use of innovation as a key component of climate change policy in the case of Alberta's Climate Change Emissions Management Corporation, utilizing a political economy approach to explain the drivers of government funding priorities. An analysis of this technology fund's investments over nine years, under two different governments, revealed that nearly half of the revenue has been used to subsidize R&D in the fossil fuels industry in the name of clean energy development, and that this priority has continued despite recent government commitments under the Paris CoP agreement. The carbon levy system that generates revenue for the fund has been unsuccessful in incentivizing facility reductions, pointing to the need for more stringent regulation. Innovation as a framework for transition to a post‐carbon economy is severely limited by its exclusion of the roles of social knowledge and citizen participation in envisaging and designing paths for change.  相似文献

The Ukraine crisis and subsequent tensions in relations with Russia urged the European Union to diversify its energy suppliers and integrate the energy markets of member states. However, the EU does not seem to have a clear strategy to strengthen its energy security. Member states are reluctant to relinquish control over their energy policy. Moreover, the diversification of fossil fuel suppliers may lead to new dependencies on authoritarian states, while the emphasis on unconventional energy sources may delay the development of renewables. A coordinated focus on renewable energy, coupled with investments in energy efficiency, appears to be the most forward-looking and climate-friendly way of reducing external dependencies.  相似文献

Torso models for ballistics research require that the mechanical properties of simulant materials must match the heterogeneous nature of tissues/organs within the human thorax/abdomen. A series of energy loss experiments were conducted on fresh porcine organs/tissues at room temperature and 37°C, using steel 4.5 mm BBs fired from a Daisy® brand air rifle. They were compared to FBI and NATO specification ordnance gelatin and a candidate surrogate material called Simulant “A”. Two CED M2 chronographs measured BB velocity. The resulting energy loss was established using KE = 1/2 mv² before and after target perforation. The combined results at room temperature and 37°C were as follows: FBI specification gelatin was similar (p > 0.05) to heart and lung, spleen was similar to NATO specification gelatin, Simulant “A” was similar to hindquarter muscle, and hindquarter muscle, kidney, and spleen were similar to each other regarding energy retardation. These results can be used as a basis for the development of simulant materials to create an anatomically correct heterogeneous model.  相似文献

目的应用衰减全反射傅里叶变换红外(attenuated total reflection-Fourier transform infrared,ATRFTIR)光谱技术分析长白猪死后肋软骨和肋骨组织随死亡时间推移的化学降解过程,为死后较长时间段内推断死亡时间提供可行的新途径和方法。方法猪放血处死后取肋软骨和肋骨离体置于20℃环境,后每72 h提取部分组织样本,进行ATR-FTIR光谱分析,并与对应死亡时间点进行相关性分析。结果随死亡时间的延长,肋软骨与肋骨FTIR的主要吸收峰峰位没有发生明显变化,而其部分峰强比出现了不同时序性的变化趋势,并与死亡时间存在良好的相关性,肋软骨较肋骨组织有更好的时序性。结论应用ATRFTIR光谱技术发现死后猪肋软骨和肋骨组织光谱学变化存在一定的规律性,有望成为基于光谱学推断死亡时间的一种新途径。  相似文献

西伯利亚联邦区能源综合体对该地区经济发展具有重要作用,但同时它也是环境的一个主要污染源。尽管西伯利亚联邦区在实施燃料能源综合体项目时采用了净化设施,但目前还不可能完全消除燃料能源部门对环境造成的负面影响。因此,能源综合体必须加强环保工作,尽快采取切实可行的措施。  相似文献

Abstract: Pressure‐sensitive tape is often used to bind explosive devices. It can become important trace evidence in many cases. Three types of calcium carbonate (heavy, light, and active CaCO3), which were widely used as additives in pressure‐sensitive tape substrate, were analyzed with Fourier transform infrared spectroscopy (FTIR) in this study. A Spectrum GX 2000 system with a diamond anvil cell and a deuterated triglycine sulfate detector was employed for IR observation. Background was subtracted for every measurement, and triplicate tests were performed. Differences in positions of main peaks and the corresponding functional groups were investigated. Heavy CaCO3 could be identified from the two absorptions near 873 and 855/cm, while light CaCO3 only has one peak near 873/cm because of the low content of aragonite. Active CaCO3 could be identified from the absorptions in the 2800–2900/cm region because of the existence of organic compounds. Tiny but indicative changes in the 878–853/cm region were found in the spectra of CaCO3 with different content of aragonite and calcite. CaCO3 in pressure‐sensitive tape, which cannot be differentiated by scanning electron microscope/energy dispersive X‐ray spectrometer and thermal analysis, can be easily identified using FTIR. The findings were successfully applied to three specific explosive cases and would be helpful in finding the possible source of explosive devices in future cases.  相似文献

Here, we present a method of extracting drug residues from fingerprints via Direct Analyte‐Probed Nanoextraction coupled to nanospray ionization–mass spectrometry (DAPNe‐NSI‐MS). This instrumental technique provides higher selectivity and lower detection limits over current methods, greatly reducing sample preparation, and does not compromise the integrity of latent fingerprints. This coupled to Raman microscopy is an advantageous supplement for location and identification of trace particles. DAPNe uses a nanomanipulator for extraction and differing microscopies for localization of chemicals of interest. A capillary tip with solvent of choice is placed in a nanopositioner. The surface to be analyzed is placed under a microscope, and a particle of interest is located. Using a pressure injector, the solvent is injected onto the surface where it dissolves the analyte, and then extracted back into the capillary tip. The solution is then directly analyzed via NSI‐MS. Analyses of caffeine, cocaine, crystal methamphetamine, and ecstasy have been performed successfully.  相似文献
