“…The overall demand for electricity increased globally in the past decade, thereby levying a pressing concern on the direction of energy governance and decisions [1][2][3]. As such, it has become imperative for countries to transition toward clean and safe energy production, such as generating electricity with technologies from solar, wind, hydro, thermal, and nuclear sources [4,5].…”

This paper offers a discussion on the social dimensions of the barriers to nuclear power generation in the country. The aim of this paper is to contribute to the literature by identifying the barriers to nuclear power generation in the Philippines and offering perspectives on the social relevance of potentially adding nuclear sources to the country’s energy mix. Given the contemporary relevance of the energy transitions globally, this work builds on the available sources over the past decade concerning nuclear energy technology in the Philippines and provides further discussions on the diverse barriers to the country’s energy transition pathway. Findings present barriers related to politics, policy, infrastructure, technical capacities, environment and information. The differences in priorities and values concerning nuclear energy reflect that the barriers to nuclear energy generation in the Philippines are social as much as technical. Based on the findings and descriptions of the current discussions on Philippine energy generation, this work provides some key points for consideration in order to deploy nuclear power plants in the country. These recommendations, however, are not definitive measures and are still subject to local conditions that may arise. This study hopes to be instructive to other countries in terms of further reflecting on the social dimensions of the barriers to nuclear energy generation.

In recent years, environmental and energy issues relating to global warming have become more serious, and there is a need to shift from conventional power generation, which emits an abundance of carbon dioxide, to renewable energy sources without emissions, such as solar and wind. However, solar power generation, which is one of the renewable energies, changes dynamically, depending on real time weather conditions. Thus, power supplied mainly by solar power generation is often unstable, and an appropriate on-demand energy management for demand-to-supply is required to ensure a stable power supply. Demand-to-supply management methods include inventory management analysis and on-demand inventory management analysis. The cumulative-control method has been used as one of the production management methods to visually manage inventory status in factories and warehouses, while the on-demand cumulative-control method is an extension of inventory management analysis. This study models a demand-to-supply management method for a solar power generation system by using the on-demand cumulative-control method in an actual case. First, a demand-to-supply management method is modeled by an on-demand cumulative-control method, using actual power data from a childcare facility in Tokyo. Next, the on-demand cumulative-control method is adopted to the case without batteries, and the amount of electricity to be purchased is estimated. Finally, the effectiveness of the maximum battery capacity and the amount of the initial charge are examined and discussed by sensitivity analysis.

“…The use of alternative energy to meet electricity and heating demand is increasing around the world, particularly in countries where those resources exist. This has become more necessary as a result of the negative effect of greenhouse gases on the environment due to the continuous use of fossil fuel to meet energy demand globally [ 1 , 2 , 3 , 4 , 5 , 6 ]. Solar photovoltaic (PV) power is one of the clean technologies that is widely used around the world, it is probably the most common technology [ 7 , 8 , 9 ].…”

Solar photovoltaic (PV) energy is one of the most widely used renewable energy options around the world. However, its electrical efficiency drops with increasing PV module temperature, it is therefore necessary to find appropriate ways to improve the performance of the module under high temperature conditions. In this study we evaluated the impact of simultaneous dual surface cooling on the PV module's output performance experimentally. The PV module's rear surface was cooled using cotton wick mesh which absorbs water from a perforated pipe and use capillary action to transfer the water down the surface of the rear side of the module. The perforated pipe is strategically positioned at the upper part of the panel and as a result, water from the tank through the holes in the pipe also spread on the front surface of the panel. The experiment recorded a temperature drop of 23.55 °C. This resulted in about 30.3% improvement in the output power of the panel. The cooled PV module also recorded an average efficiency of 14.36% against 12.83% for the uncooled panel. This represent a difference of 1.53% which is 11.9% improvement in the electrical efficiency of the cooled panel. In effect, the proposed approach had a significant positive effect on the energy yield of the PV system.
