With the increasing demand for clean and low-carbon energy, high proportion of renewable energy has been integrated into the receiving-end grid. The grid-side energy storage project can ensure the safe and stable operation of the grid, but it still faces many problems, such as high initial investment, difficult operation and maintenance, unclear profit model, lack of business mode. Therefore, it is of great significance to evaluate the comprehensive benefit of energy storage projects in order to guide the sustainable development of large-scale energy storage projects and power system. By studying the technical and economic characteristics of energy storage, this paper establishes a comprehensive evaluation system from four dimensions of energy efficiency, economic, social, and environmental benefit. Combined with typical business modes and determining the subdivision index system of different modes, the comprehensive benefit evaluation model of grid-side commercial storage project based on Fuzzy-Analytic Network Process (ANP) approach is established. Empirical analysis of a 100-megawatt storage project is carried out to evaluate the project benefits comprehensively, the potential problems of the market development and business mode of the grid-side large-scale storage project are discussed, and the future development orientation and suggestions are put forward.

Abstract Economists often default to the assumption that cash is always preferable to an in-kind transfer. Do beneficiaries feel the same way? This paper addresses this issue using longitudinal household data from Ethiopia, where a large-scale social safety net intervention (PSNP) operates. Even though most payments are made in cash, and even though the (temporal) transaction costs associated with food payments are higher than payments received as cash, most beneficiaries stated that they prefer their payments only or partly in food. Higher food prices induce shifts in stated preferences toward in-kind transfers. More food-secure households, those closer to food markets and to financial services are more likely to prefer cash. Though shifts occur, the stated preference for food is dominant: In no year do more than 17 percent of households prefer only cash. There is suggestive evidence that stated preferences for food are also driven by self-control concerns.

This empirical study investigates large urban park cooling effects on the thermal comfort of occupants in the vicinity of the main central park, located in Madrid, Spain. Data were gathered during hot summer days, using mobile observations and a questionnaire. The results showed that the cooling effect of this urban park of 125 ha area at a distance of 150 m could reduce air temperatures by an average of 0.63 °C and 1.28 °C for distances of 380 m and 665 meters from the park. Moreover, the degree of the physiological equivalent temperature (PET) index at a distance of 150 meters from the park is on average 2 °C PET and 2.3 °C PET less compared to distances of 380 m and 665 m, respectively. Considering the distance from the park, the correlation between occupant perceived thermal comfort (PTC) and PET is inverse. That is, augmenting the distance from the park increases PET, while the extent of PTC reduces accordingly. The correlation between these two factors at the nearest and furthest distances from the park is meaningful (p-value < 0.05). The results also showed that large-scale urban parks generally play a significant part in creating a cognitive state of high-perceived thermal comfort spaces for residents.

This treatise outlines developments in disaster management focusing on earthquake disaster measures taken by the Japanese and Tokyo Metropolitan Governments since the 1980s. The 1978 Large-Scale Earthquake Measures Special Act on conditions for predicting the Tokai Earthquake significantly changed the direction of earthquake disaster measures in Japan. The Tokyo Metropolitan Government undertook its own earthquake disaster measures based on lessons learned from the 1964 Niigata Earthquake. In the 1980s, it began planning urban development disaster management programs for upgrading areas with high wooden houses concentration - still a big problem in many urban areas of Japan - which are most vulnerable to earthquake disasters. The 1995 Great Hanshin-Awaji Earthquake in Kobe brought meaningful insight into both to earthquake disaster measures by the Japanese Government and by the Tokyo Metropolitan Government and other local governments nationwide. Long-term predictions concerning possible earthquake occurrence have been conducted throughout Japan and new earthquake disaster measures have been adopted based on this long-term prediction. The Tokyo Government has further completely revised its own earthquake disaster measures. As a review of measures against foreseeable earthquake disasters based on developments in disaster management measures, this treatise provides invaluable insights emphasizing urban earthquake disaster prevention developed in Japan over the last 30 years that readers are sure to find both interesting and informative in their own work.

Large-scale coastal reclamation has become a significant land use issue worldwide for urban construction and economic development. The reclamation of coastal wetlands brings substantial economic benefits, however, the structure and function of coastal ecosystem are affected by drivers of human-caused landscape change. This research takes Hangzhou Bay and Zhoushan Islands as the case study to investigate the correlation between the coastal geomorphic complexity and the tidal range reduction rate, and to explore the control technical indexes of the design in reclamation area by a multidisciplinary approach that integrates the basic theories and quantitative methods of fractal geometry with the hydrodynamic mechanism of ocean dynamics. The results show that the coastal tidal range reduction rate is closely related to the coastline fractal dimension and patch shape index (D, S), and reveals the influence of the complexity of the coastal landscape on the tidal energy loss. In addition, based on model predictions, it can be found that the large-scale reclamation in Zhoushan will cause a serious decline in the complexity of the coastal landscape and the reduction of tidal energy, which is extremely detrimental to coastal disaster prevention. In the end, the scientific design theory and quantitative control indexes of reclamation are put forward to provide theoretical basis and design reference for future coastal reclamation and disaster prevention.

Studies assessing people’s willingness-to-pay for carbon offsets are overwhelmingly grounded in hypothetical stated-preference approaches. Here, we report on a large-scale observational field study involving a final sample of 63,520 bookings made with a European airline, allowing us to gauge willingness-to-pay for offsets in a revealed-preference approach. Our pre-registered study shows that the median willingness-to-pay to voluntarily offset a ton of CO2 from flight-related emissions is zero, with the mean willingness-to-pay being around 1 EUR. Neither prices of the offset nor airfares are predictive of offsetting behavior in a highly powered sample. Climate vulnerability of the destination has no significant impact on the compensation decision either. On the other hand, higher ancillary spending is associated with an increased likelihood to compensate, even though the effect size is low due to the general unwillingness to internalize flight-related emissions. Additionally, we find the choice of a vegetarian meal to be of similar predictive power (significant, but low in effect size given an overall low proportion of passengers choosing a vegetarian meal). Our results inform existing research on stated preferences as well as mitigation efforts relying on voluntary climate action.
