Company participation in supporting national energy security through collective installation of rooftop solar panel of employees’ houses as an effort to accelerate increased utilization of solar energy

It is common practice, in the production of photovoltaic energy to only use the south-exposed roof surface of a building, in order to achieve the maximum production of solar energy while lowering the costs of the energy and the solar technologies. However, using the south-exposed surface of a roof only allows a small quota of the energy demand to be covered. Roof surfaces oriented in other directions could also be used to better cover the energy load profile. The aim of this work is to investigate the benefits, in terms of costs, self-sufficiency and self-consumption, of roof integrated photovoltaic technologies on residential buildings with different orientations. A cost-optimal analysis has been carried out taking into account the economic incentives for a collective self-consumer configuration. It has emerged, from this analysis, that the better the orientation is, the higher the energy security and the lower the energy costs and those for the installation of photovoltaic technologies. In general, the use of south-facing and north-facing roof surfaces for solar energy production has both economic and energy benefits. The self-sufficiency index can on average be increased by 8.5% through the use of photovoltaic installations in two directions on gable roofs, and the maximum level that can be achieved was on average 41.8, 41.5 and 35.7% for small, medium and large condominiums, respectively. Therefore, it could be convenient to exploit all the potential orientations of photovoltaic panels in cities to improve energy security and to provide significant economic benefits for the residential users.

The Difference

People can make solar energy alternative energy by employing solar panels to generate electricity. The utilization of solar energy on a solar panel to generate electricity is affected by the weather and the duration of the radiation, and they will affect the solar panel’s temperature. There are various types of solar panels that can be found on the market today, including Mono-Crystalline and Poly-Crystalline. The difference in the material used needs to be observed in terms of temperature changes in the solar module. Our study’s findings showed that a change in the temperature would impact the solar panel’s output voltage, and the solar panel’s output voltage would change when it was connected to the load although the measured temperatures were almost the same.

Development Goals

Energy was not stated as one of the millennium development goals (MDGs) but played an indirect role in helping meet the MDGs especially in the areas of housing, health, education, and poverty reduction in Africa. In contrast, the United Nations’ 2030 agenda includes 17 sustainable development goals (SDGs), one of which is devoted to energy. SDG7 seeks to ensure “access to affordable, reliable, sustainable, and modern energy for all,” thereby creating a vital role for the energy sector to join in the task of achieving SDGs. Renewable energy including solar energy will play a significant role in improving energy security in Africa and diversifying the energy mix by reducing reliance on fossil fuels. This chapter examines the advantages of solar technologies in the context of social, economic, and environment benefits using case studies from Kenya and South Africa. This chapter also examines some of the key challenges that are associated with the application of solar energy technologies in these countries. Finally, the chapter discusses how solar energy technologies can help meet SDGs and summarizes policy and programs targeting the promotion of solar energy technologies for the implementation of SDGs.

Definition Of

Abstract National energy security, parallel with the ultimate goal of emissions reductions, is of utmost priority for the Chinese government. In order to comply with the requirements set by the Kyoto Protocol, the Chinese government announced, on 25 November 2009, that 2020’s CO2 emissions would be reduced by 40–45 per cent in accordance with the data collected from 2005. Said goal was met three years ahead of schedule. Even in light of such an accomplishment, however, commentators suggest that the overall nationally determined contributions (NDCs) made by the Parties belonging to the Paris agreement are not enough to reduce global warming by even 2°C. This article focuses on the concept of energy security in assessing whether, and how, the priorities related to climate change are gradually changing. After analysing climate change’s impact on China, conducted via an analysis of the study’s available literature and through the support of international data, this article mainly focuses on the concept of energy security, itself. Under the second section, based on the examination of China’s efforts to transition towards a low-carbon economy, the authors provide a holistic definition of energy security through the lens of three dimensions: energy supply security, energy economy and energy ecological security. The third section, in turn, addresses the relationship between energy security and climate change. The results presented in the conclusion insist that, in order to strengthen environmental protection in China, it is crucial to reform the highly inefficient and strictly regulated national energy market. In doing so, China’s transition to a low-carbon society and economy could prove less painful, as China’s available resources offer the potential for a strengthened ecological dimension and sustained socio-economic development.

This study aims to discuss the policy of using renewable energy in the form of rare metal eart as an effort to build national energy security. The research method used a legal research looking from various perspectives in social science. Law is seen as a space for the process of scientific study in order to seek truth. The use of relevant legal research wants to understand the law more thoroughly. In performing implementation analysis, using the method of Regulatory Impact Assessment (RIA) with focus on energy regulation. The results of the study show that: First, the policy of the Indonesian republic government regarding the use of new energy and renewable energy aims to prepare the carrying capacity of national energy security. This policy has not fully gone well. The policy is not supported by consistency in issuing derivative policies. Second, the use of new energy and renewable energy, especially rare earth metals as part of efforts to encourage national energy security in Indonesia is still very far from expectations. The use of rare eart metal is only around 0.7% of the use of new energy. Efforts to explore and exploit rare earth metals have not been carried out in a timely manner. Whereas the potential of rare earth metals is a strategic community and has the potential to encourage national energy security in Indonesia. Indonesia is projected to produce rare earth metals reaching 20% of the world's supply.
