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...

In recent two decades, countries focused on minimum extraction of fossil fuels and utilized the renewable energies based on countries' policies and the environmental considerations. Thus, choosing the best renewable energy alternative is a significant role to investment on them. Among the classical decision approaches that have used in the literature, the hesitant fuzzy sets (HFSs) theory is ap...

Introduction: Current energy sources are coming to end and one of the main priorities of the country’s management is the energy recovery from renewable energy. Considerable quantity of municipal solid waste (MSW) is one of the most serious urban pollution sources. Impact assessment matrix is a new and fast tool for Environmental Impact Assessment (EIA). Materials and Methods: In this regard, r...

Purpose The purpose of this study is to assess the nexus between governance and renewable energy consumption in Sub-Saharan Africa (SSA). Design/methodology/approach focus on 44 countries SSA with data from 1996 2016. empirical evidence based Tobit regressions. Findings It apparent findings that political institutional are negatively related sampled countries. unexpected clarified policy implic...

Deforestation shows the constant environmental degradation that occurs worldwide as a result of growth economic activity and increase in population. This research examines causal link between renewable energy consumption, GDP, GDP2, non-renewable price, population forest area high, middle- low-income countries. Based on data obtained from World Development Indicators, autoregressive distributed...

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...
