The study investigates the long run relationship and causal relationship between energy consumption and economic growth in the Brics countries during the period 1990 – 2013. The Pedroni panel co-integration method is applied to analyse the co-integration relationship among the variables. The...

Since the early 1970s there has been a worldwide upsurge in the price of energy and in particular of gasoline. Therefore, demand functions for energy and its components like gasoline have received much attention. However, since confidence in the estimated demand functions is important for use in...

This paper explores the 2021-2022 global energy crisis. The 2021-2022 energy crisis was caused by many factors including the global campaign to reduce carbon emission, the shortage in fossil fuel reserves due to divestment from fossil fuels, the halt in oil production due to the COVID-19...

The compressed air flow in the pneumatic networks is studied from thermodynamic point of view. Generally speaking, the flow issue is presented as next: knowing the characteristics p1 (pressure), v1 (specific volume), T1 (temperature) and the fluid speed w1, in the initial section (point 1), of a...

The fresh calculation of the centrifugal-type compressor characteristics at the aspirations parameters and rotations modification has a significant importance in practice, because the tests of compressors generate high energetic consumptions. The solution of the problem is based on replacement...

This study is focused on the construction of long – term scenarios for the transition to renewable energy. Utilizing European and national targets, the key objective of this work is to investigate how these targets are reflected in both economic and environmental terms. The constructed model...
