Energy Autonomy

The purpose of this study is to determine the impact of households’ energy autonomy on a country’s energy independence level, to identify prospects and risks. To assess the economic efficiency of households’ energy autonomy, the study used a modeling method based on maximizing the net present value, determining the average notional cost of energy efficiency and the level of energy independence in 20 countries. Based on the analysis of the volumes of electricity consumption by households in the studied countries for the period 2000–2018, it was revealed that in developed and developing countries there is an increase in this indicator. Diagnostics of the investment attractiveness of the installation and operation of energy systems for households makes it possible to determine the boundaries of a possible increase in the level of their energy autonomy. The scientific novelty of the research is represented by the proposed methodological approach, which makes it possible to assess the level of energy dependence of countries, possible deviations, and an increase in households’ energy autonomy in relation to the risk limit of energy dependence. The proposed methodological approach allowed the authors to prove the positive impact of increasing households’ energy autonomy for most developed countries. The most positive effect is characteristic of the leading countries in fossil energy market.

Electrical Consumption

The latest measure for the development of photovoltaics in Greece utilizes the net-metering scheme. Under this scheme the energy produced by a PV system may be either consumed by the local loads or be injected to the grid. The final cost reported in an electricity bill depends upon the energy produced by the PV system, the energy absorbed from the grid and the energy injected to the grid. Consequently, the actual electricity consumption profile is important to estimate the benefit from the use of this renewable energy source. The state latest statistics in Greece for households reveal that the typical electrical consumption is 3750 kWh while 10244 kWh are consumed in the form of thermal energy. We adopt in our calculations the above amount of electrical energy but assume four different scenarios. These different hourly profiles are examined to study the effects of synchronization upon the final cost of energy. The above scenarios are applied to areas in different climate zones in Greece (Heraklion, Athens and Thessaloniki) to examine the dependence of the hourly profiles and the solar potential upon the financial data with respect to internal rate of return, payback times, net present value and the levelized cost of energy. These parameters are affected by the initial system cost and the financial parameters.

The Impact

In Financial Systems, the impact of Free Cash Flow (FCF) on the performance of a company has been in the center of academic discourse in recent years. Several studies have tried to ascertain the nature and magnitude of the relationship between free cash flow and firm profitability with conflicting results coming from different scholars. The main objective of this research work was to examine the impact of FCF on the profitability of quoted manufacturing firms in the Nigerian and Ghana stock exchanges. Data were pooled from twenty (20) different companies (ten each from Nigeria and Ghana) for a period of six years (2012 – 2017). A panel data estimation model was used to measure the impact of FCF and other performance metrics on the Return on Assets (ROA), which is our chosen profitability measure. The results show a positive but insignificant relationship between FCF and ROA both for Ghana and Nigerian manufacturing firms. Also, sales growth showed a positive impact on profitability of both countries while leverage negatively impacted on profitability. with Ghana being significant at 5%. The implication of the findings of the study is that it makes no business sense for companies to keep piling up excess funds beyond that which is needed for transactional purposes. The similarity between the results from Ghana and Nigeria in most of the variables shows that the findings of this study can be generalized to other countries. Based on the findings of the study, we recommend that the management of companies should strive to keep only the minimum needed free cash flow while the rest should be invested in other projects with positive net present value

Aims: This systematic review aims to assess the impact of Balanced Scorecard (BSC) implementation at Health Care Organizations (HCOs) on Health Care Workers' (HCWs') satisfaction, patient satisfaction, and financial performance. Up to now, no previous systematic reviews have performed a comprehensive and rigorous methodological approach to figure out the impact of BSC implementation in HCOs. Methods: This systematic review was prepared according to PRISMA guidelines. PubMed, Embase, Cochrane, and Google Scholar databases, as well as Google search engine, were inspected to find all BSC implementations at HCOs until 20 September 2020. Then the resulted articles were screened to find the implementations which measured the impact of BSC on HCWs' satisfaction, patient satisfaction, and financial performance. Quality assessment was performed using the Standards for Reporting Implementation Studies: (StaRI) checklist. Results: Out of 4031 records, 20 articles were finally included for measuring one or more of the three impact types. 17 measured the impact of BSC on patient satisfaction, 7 on HCWs' satisfaction, and 12 on financial performance. Studies with higher quality had a higher positive impact. Conclusion: This paper offers evidence to HCOs and policymakers on the benefits of implementing BSC. BSC implementations showed a positive impact on patient satisfaction and financial performance in HCOs. However, less impact was found on HCWs' satisfaction, which should be given better consideration in future BSC implementations. High and medium-quality BSC studies were associated with higher positive impacts than low ones. BSC can be utilized as an effective tool to improve HCOs' performance during the COVID-19 pandemic.

The Impact

Inflation could likely cause devastating impacts where high inflation can harmful economic and social circumstances. However, only limited studies try to find the impact of inflation on the quality of air. The aim of this study is to investigate the empirical linkage between inflation and air pollution in Indonesia covering the period of 1981 until 2017 by using an error correction model (ECM) methodological approach. The result of study suggests that in the short run, higher inflation is causing the lower level of air pollution. Similarly, in the long run, higher inflation is also affecting the lower level of air pollution. While there are a lot of negative impacts of inflation in Indonesia, the finding in this study indicates a positive impact of inflation in Indonesia, which is higher inflation can reduce the air pollution. The results seem contradict with the target of central bank of Indonesia to have a low but positive rate of inflation. Based on the findings, the study suggests the policymakers in Indonesia to support a robust role of inflation stability in achieving targets related to the reduction of air pollution.

The Impact

The relevance of this study is due to the importance of assessing the prospective dynamics and structure of demand for energy carriers when developing and making strategic decisions in the field of energy and economic security of the country and its regions. The advance of digital technology redefines the properties of electric power supply systems, erases the boundary between electric power producers and consumers, and impacts the formation of electricity price and demand in the region. This study presents a method of electricity costing in the regional power system, which serves as an integral part of the approach to assessing the impact of intelligent systems development on the demand for electricity in the region. The approach is unique in that it simulates the behavior of electricity consumers and producers of various types as they pursue their own interests and assesses the impact of this behavior on the demand and price of electricity in the regional power system. Determining the cost of electricity in the system is based on the consistent alignment of the required amount of electricity consumption with the capabilities of producers seeking to achieve their best economic performance. Each producer is described as an optimization model, which is a standalone agent in a multi-agent power system model.

The Impact

The population is aging in developed countries. This aging process results in many changes, both physical and mental. Over the years, there has been a gradual decline in the level of cognitive functions closely related to the ageing process, which is most often connected with ageing diseases such as dementia. So far, pharmacological treatment has not yet been able to cure this neurological disorder. Health policies around the world seek to find alternative programs and strategies to help a healthy population prevent cognitive decline and prolong active life. One such strategy appears to be physical activity. The aim of this review is to discuss the impact of physical activity on cognitive performance among healthy older individuals. The methodology of this study is based on a systematic electronic literature search of available studies found in three databases: PubMed, Web of Science and Scopus. The findings suggest that any physical activity in older age seems to have a positive impact on the improvement of cognitive function. Furthermore, it appears that dancing, due to its multiple mechanisms, might have the biggest effect on the enhancement of cognitive performance in healthy older individuals. However, controlled clinical trials of physical activity intervention in older adults are rare. Therefore, further research in this area (particularly on the amount of physical activity, its intensity and type) is needed.

The study was made of the relationship between GDP growth rates and individual components of its final use by combining factor analysis using the principal component method and regression analysis. The period from 1955 to 1980 was studied using data on the average annual growth rate of components over fiveyear periods in the countries of the non-socialist world. The growth rates of the various components of the use of GDP at different stages as the fourth technical and economic structure of the fourth dominates and the development of crisis phenomena in the economy has had a variable impact on economic growth. During the crisis period, the impact of the growth of all components of using GDP on economic growth has dropped sharply. The greatest role in this period was played by the growth of current expenditures of the state. Comparison of the structure of the use of GDP using factor analysis by the method of principal components was carried out by the average annual values for the period from 1950 to 1980. As the development crisis approaches, as the models show, the influence of factors of the structure of using GDP on economic growth decreases. During the entire period, high levels of government spending had a negative effect on economic growth. The impact of exports and imports was positive for the entire period studied. Overcoming the crisis in the economies of developed countries led to a transition to a positive impact of investment on economic growth.

There has been an ongoing debate about the impact of trade openness on the health. This study aims to inform this debate by comparing health impacts of trade in services vis-à-vis trade in goods. Prima facie, the former, due to association with the higher human capital requirement and less pollution, may have a higher positive health impact. The main finding is that the trade in services has a higher positive impact on the health status compared to that of the trade in goods. However, for the least developed countries trade in goods is the dominant factor impacting the health status.

Future electricity tariffs are expected to increase. To overcome this condition, arise the idea how the residential can generate its own electricity by exploiting the potential of solar energy. However, there are some constraints in its implementation due to the difference of the initial cost and sales from solar PV systems in various region of Indonesia. The purpose of this study is to determine the impact of initial cost on the levelized cost of energy from the system. This study uses the calculation of Levelized Cost of Energy (LCoE) and economic feasibility analysis through the calculation of net present value with net metering scheme. Manado is the most optimal city to implement this system. The initial cost will affect to the LCoE, the high initial cost can be covered by the amount of cash flow generated by the system which has huge solar irradiation potentials.
