Installed rooftop solar PV generation in the U.S. has grown rapidly to meet the increasing electricity demand, reduce reliance on expensive fossil fuel, while reducing greenhouse gas emissions. According to Wood Mackenzie Power & Renewables and the Solar Energy Industries Association (SEIA), the U.S. topped 2 million solar PV installations in 2019, hitting a milestone previously reached only by two countries — Australia in 2018 and Japan in 2014. Delaware, for example, average solar electricity consumption increased at a compound growth rate of 138% from 2010-2016. Some of the factors contributing to this dramatic growth of solar power include the declining cost of solar equipment, installation, and operation and maintenance (O&M) which make investment in rooftop PV attractive for municipal and state buildings, universities, colleges, K-12 schools, and hospitals (often abbreviated as MUSH). Although investment opportunities in urban rooftop PV in privately-owned residential and commercial buildings have also grown significantly in Delaware, as consumers seek greater control of their energy use, MUSH buildings provide the most attractive PV investment potential due to their public function and better institutional capacity. This report describes our findings for research conducted with the support of the Delaware General Assembly — Science, Engineering and Technology (SET) Services Program in 2018-2019. The analysis for both Wilmington Solar City Plant (SCP) and Newark SCP has identified a priority buildingscape with significant solar technical potential. The results of a direct purchase option analysis assuming a utility-scale opportunity, show feasible PV system deployment at 9.68 cents/kWh for both cities. Current average retail costs for electricity in the two cities are greater than 14 cents/kWh.
安装在屋顶的太阳能光伏发电在美国迅速增长，以满足日益增长的电力需求，减少对昂贵的化石燃料的依赖，同时减少温室气体排放。根据Wood Mackenzie Power &根据可再生能源和太阳能工业协会(SEIA)的数据，美国2019年的太阳能光伏安装量超过200万，创下了此前只有澳大利亚(2018年)和日本(2014年)两个国家达到的里程碑。例如，特拉华州的平均太阳能用电量从2010年到2016年以138%的复合增长率增长。促成太阳能发电急剧增长的一些因素包括太阳能设备、安装和运营维护(O&M)成本的下降，这使得屋顶光伏投资对市政和国家建筑、大学、学院、K-12学校和医院(通常缩写为MUSH)具有吸引力。尽管在特拉华州，私人住宅和商业建筑的城市屋顶光伏投资机会也显著增长，因为消费者寻求更好地控制他们的能源使用，MUSH建筑由于其公共功能和更好的机构能力，提供了最具吸引力的光伏投资潜力。本报告描述了我们在2018-2019年特拉华州大会科学、工程和技术(SET)服务计划的支持下进行的研究结果。对威尔明顿太阳能城市工厂(SCP)和纽瓦克太阳能城市工厂的分析已经确定了具有重要太阳能技术潜力的优先建筑景观。直接购买选项分析的结果显示，假设一个公用事业规模的机会，可行的光伏系统部署在9.68美分/千瓦时两个城市。目前，这两个城市的平均电力零售成本超过14美分/千瓦时。

Unlike many other places around the globe, Hong Kong is a small city with a high population density. Some housing units are built near the sources of an externality, such as a landfill site. As the blocks of buildings are particularly tall, many are walled buildings that block the bad odor from the landfill. Thus, the wind blowing from a landfill site may not affect the entire building estate. Some buildings are more heavily affected than others, partly because walled buildings built near landfills are rare. Only a few studies currently examine the correlation between wind direction and the prices of walled buildings. In this paper, we aim to bridge this research gap by illustrating Hong Kong as a case study. Most previous research studies only examine a few factors affecting housing prices. Modern big data is characterized by its large volume of data, which includes various types of data that analysts would not necessarily sample, but instead merely observe to track what happens. Therefore, another innovative point of our paper, is that we adopt a big data approach to study this issue. In this aspect, this paper is the first of its kind. There are 53,071 observations in the 1999 to 2014 dataset, with 2,175,911 data entries. Our results reflect that when more municipal solid waste is sent to the South East New Territories Landfill, residents’ complaints in Tseung Kwan O increase. However, entire property prices in the region also increase, which rejects our hypothesis. We speculate that as more people become aware of the housing estate due to complaints, with only a limited number of housing units affected by the smell, since the wind usually only blows in certain directions, the “advertisement effect” originating from complaints about the bad smell boosts the property prices of the unaffected units. That is, people become aware of the existence of the property, visit the site, and discover that only specific units facing one particular direction are affected. Then, they purchase units that are unaffected by the smelly wind, leading to an overall increase in property prices. The study’s results may provide a new perspective on urban planning, and possible implications for other cities in view of the constant increase in population and expansion of landfill sites.

In this paper, I investigate the respective economic returns to capital and inherent ability by studying the recovery of fishermen in Aceh, Indonesia, from the 2004 Indian Ocean Tsunami. Since the natural disaster wiped out almost all existing differentials in productive physical capital among fishermen, the subsequent random assignment of aid boats generates a natural experiment. Using panel data from fishing households, I first examine whether the transfer of physical capital increases overall productivity. Second, I investigate whether fishermen who were relatively more productive pre-tsunami retain their productive edge ex-post. Focusing on the sample of fishermen who lost their pre-tsunami boats, I find that the impact of aid boat length on fishing revenue is positive but diminishes over time. In contrast, I find that the impact of pre-tsunami productivity on fishing revenue increases. These results suggest that (i) returns to inherent ability, measured by pre-tsunami productivity, are more important than returns to physical capital in the long run, and (ii) the redistributive effects of boat aid on productivity are small and temporary.

In a European perspective, the electricity markets have been experiencing major changes via deregulation, new technologies and changes in the production mix. Together with the daily and seasonal peak hours on the demand side, the changing markets put pressure on increased flexibility to handle and sustain balance in the grid systems. This paper focuses on the demand side and analyzes preferences related to demand management of Swedish households' energy use. In a web-based choice experiment respondents were faced with three hypothetical electricity contracts. The choices of preferred contracts revealed preferences for attributes related to external control of heating, household electricity and information dissemination (integrity). The results show that people put a substantial value on not being controlled, illustrated by compensations up to thousands of SEK for accepting a contract characterized by external control of energy use in various dimensions. In addition, the results show that household composition, age, gender and income play a role for the perceived discomfort from the external control and information dissemination.

The Italian water sector has encompassed major changes since mid?90s when law 96/94 has entered into force. Next to private participation, integration of services and growth in production scales, the reform was intended to revolutionize the traditional financial model almost fully based on public funds. Although citizens, politicians and experts on water services have been debating for a long time on the impact of the reform on the industry, as well as on the fairness of a tariff system inspired by the concept of full cost recovery, we are still on a state of uncertainty. The final purpose of this paper is to provide regulators with guidelines that could be used to revise water tariffs in a way that may be cost?efficient, sustainable and fair to the most. According to the analyses, which rely on firm?specific Xinefficiency scores, despite a satisfactory mean level of performance, in the period under investigation, efficiency improvements have been limited. Moreover, the results demonstrate that both the ownership structure and politics do have an impact on the efficiency of the firms: in particular, public shareholding and centreright local governments negatively affects firms’ performances. To this respect, we think that a more effective regulation would also have the side effect of loosening the ties between politicians and managers.

The humanitarian emergency that followed the TokweMukosi flooding in Zimbabwe has been widely covered in the media. The humanitarian crisis that always follow natural hazards such as floods have been subjected to various researches, however they have been mainly assessing the impact of floods on livelihoods. This study revealed that a plethora of challenges face NGOs at Chingwizi in their endeavour to ameliorate the humanitarian emergency.

We consider a class of evolution equations describing the population dynamics in the presence of a carrying capacity depending on the population with delay. In an earlier work, we presented an exhaustive classification of the logistic equation where the carrying capacity is linearly dependent on the population with a time delay, which we refer to as the "linear delayed carrying capacity" model. Here, we generalize it to the case of a nonlinear delayed carrying capacity. The nonlinear functional form of the carrying capacity characterizes the delayed feedback of the evolving population on the capacity of their surrounding by either creating additional means for survival or destroying the available resources. The previously studied linear approximation for the capacity assumed weak feedback, while the nonlinear form is applicable to arbitrarily strong feedback. The nonlinearity essentially changes the behavior of solutions to the evolution equation, as compared to the linear case. All admissible dynamical r...

This paper analyzes the impact of the Indian Ocean Tsunami in 2004 and the Nias earthquake in 2005 on population dynamic across regions in Aceh and North Sumatera. We find no evidence that the disasters affected the regularity of size-distribution of the regions. The estimates of a population growth model yield clear evidence that the disasters had only a temporary impact. This study provides indicative evidence for the relevance of the locational fundamental theory and rejects the random growth explanation.

The shortcomings of a commonly used technique, difference in difference, have recently been addressed with Generalized Difference in Difference (GDD) method. This study relaxes some of the restrictions of GDD and utilizes hurricanes as exogenous shocks to determine their impact on wages and employment in three different industries (construction, manufacturing, and leisure & hospitality) in Louisiana from 2001 to 2010. The results suggest that the hurricanes have a significant adverse effect on wages in construction and leisure & hospitality sectors. During the time period studied, the parishes that are directly hit by a hurricane suffer a 6 percent drop in wages in leisure and hospitality sector while the neighboring parishes suffer 5 percent drop in construction sector.
