Photovoltaic (PV) solar farms and hydropower stations can create a plant that do more than the two resources acting independently as long as, with the addition of a solar project, hydroelectric plants increase its annual availability of power and economic efficiency, taking advantage of the storage capacity of energy that a hydroelectric reservoir can provide. The objective of this paper is to investigate the potential of Brazilian hydropower plants regarding these issues using the large amount of available data recorded. There exists a potential increase in the energy production of 53.3 TWh per year based on the proposed optimized solution for the Brazilian hydropower stations with significant water storage capacities assessed in this paper. This energy is equivalent to an additional capacity factor of approximately 20% to the original 31.5 GW installed hydro capacity or almost 10% of the Brazilian electricity demand in 2018. This result would be at the expenses of a huge deployment of 34 GW of solar PV floating power plants installed close to the reservoir dams that must yet prove to be economically feasible. However, on the other hand, this proposal can create a virtuous cycle for the solar industry in Brazil and speed up the viability of solar cell costs, since setting up and connecting the PV plants are greatly simplified when done in existing hydropower stations facilities.

Following numerous global scientific studies and major international agreements, the decarbonization of energy systems is an apparent and pressing concern. The consequence of continued emission growth tied to rising global average temperatures is difficult to predict, but against a background of other natural and human-induced disasters, may create a situation, from a positive perspective, where each disaster event triggers "build back better" responses designed to speed the transition toward low carbon, resilience-oriented energy systems. This article examines the potential for disaster-triggered responses in communities, at various local and regional levels, in four industrial economies in the Asia Pacific region: Japan, China, Australia, and the USA. Seven case studies were evaluated against a set of criteria that exemplify the key aspects of resilient energy systems. The research results suggest that a new space of innovation does emerge in post-disaster situations at a range of local and regional scales. The greatest potential benefit and opportunity for significant gains, however, appears to manifest at the small community level, and the ultimate challenge relates to how to mainstream local innovations into state and national level transformation on energy systems so as to enhance resilience and promote rapid decarbonization.

“…It is worth mentioning that the upper reach of the West River basin is known for its typical karst landform featuring thin soil cover and sinkholes. The karst landform has led to droughts prevailing in the upper reach of the West River basin (Guo et al, 2013;Long et al, 2014;Fang et al, 2017). Therefore, as shown in Figure 1, there are a total of seven subregions for risk analysis in the PRB.…”

Abrupt transitions between droughts and floods present greater challenges to water resource management than independent drought or flood events. It is therefore of significant importance to further include drought-flood transitions in the risk analysis of water-related hazards under a changing climate. This study more generally evaluates the risks of combinations of dry and wet conditions between adjacent seasons. First, dry and wet conditions are monitored by the standardized precipitation index (SPI). Then, a copula-based framework is proposed for the deviation of joint return periods of dryness-wetness combinations at different severity levels. In addition, SPI series trend detection is conducted using the Mann-Kendall test to analyse the temporal-spatial changes in dry and wet conditions. Wavelet analysis is applied to investigating correlations of dry and wet conditions with climate variability signals, which may provide predictive signals for dryness-wetness combinations. The results of a case study in the Pearl River basin (PRB), China over the period of 1960-2015 indicate that (a) the flood season (from July to October) tends towards dryness and there are wetting trends in the late autumn and winter; (b) as the joint return period is considered the proxy for the risk of dryness-wetness combination, shorter joint return periods remind a higher risk of suffering from abrupt dryness-wetness transitions in the spring-summer and summer-autumn, as well as the more frequent occurrence of continued dryness/wetness in the autumn-winter and winter-spring; (c) the western and eastern PRB are separately characterized by intensified and reduced risks of the most frequent combinations under a changing climate; and (d) El Niño-Southern Oscillation events, the Pacific Decadal Oscillation and sunspot activities have a close association with dry and wet conditions in the PRB. The study provides a supplement for the current risk map and may benefit the early warning and mitigation of water-related hazards.
