research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...

This study attempt to fill the research gap by figuring out dynamic effects of foreign capital inflows effect on renewable energy and non-renewable consumption using time series non-linear ARDL approach for BRICS from 1991 2019. Non-linear estimates show that positive change in has a Brazil, India, South Africa long run. Also, negative exhibits negatively liked with economies, except Russia We ...

The displacement of non-renewable fossil fuels by renewable energy resources has occurred at a low rate in the USA. But a large number of drivers is expected to cause significant expansion of the US renewable energy industry in the near future. Included among the extrinsic drivers, or those that are not directly related to renewable energy resources, are reductions in natural gas and crude oil ...

We evaluate the N-shaped environmental Kuznets curve (EKC) using panel quantile regression analysis. We investigate the relationship between CO2 emissions and GDP per capita for 74 countries over the period of 1994-2012. We include additional explanatory variables, such as renewable energy consumption, technological development, trade, and institutional quality. We find evidence for the N-shape...

Abstract. One of the most important research directions in the building sector is reducing the energy consumption. In Hungary the residential sector is the biggest energy consumer with 32% from the total energy consumption of the country. One possibility to decrease the energy consumption for heating is using renewable energy sources. In this paper a short description of the heat pump technolog...

This paper adopts the vector auto-regression model (VAR) to study the dynamic effect of renewable energy consumption on carbon dioxide emissions. Our model is based on a given level of primary energy consumption, economic growth and natural gas consumption in the US, from 1990 to 2015. Our results indicate that a long-running equilibrium relationship exists between carbon emissions and four oth...

Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distribute...

In recent years, energy predicament and environmental problems in the world caused by fossil fuels combustion make us to pay serious attention to optimizing energy consumption and using renewable energies. One of the potential renewable energies which can be helpful in electricity generation is harness wind and water energy or using these two kinds of energy simultaneously. In this study, to pr...

Energy systems operation in isolated areas is frequently based on imported fossil fuels, which is a problem in different dimensions including environmental, economic and security of supply, with the latter being particularly relevant for any isolated system like Islands. Renewable energy is regarded as a solution to this problem, mainly in its transformation to electricity. This, however, exclu...
