Much of the energy used in the world is associated with the construction sector, and one of the ways to reduce that energy consumption is to do each constructive process in an energetically efficient way. The aim of this paper is to present results from an energy efficiency program in the...

Circular economy (CE) is a new trend in balanced development, directed at limiting consumption of resources and minimising waste production. In consideration of the European Commission's (EC) postulates of the CE implementation, the article aims at verifying whether coal power plants in...

The greening of power engineering is a component of the ecologically sustainable development strategy being implemented in the world and also a pillar of the EU sustainable energy policy. One of the main fields of activity for the greening of power engineering are actions for improving power...

Oil and gas exploration companies (E&Ps) exhibit large variations in earnings due to volatile oil and gas prices. Furthermore, their primary asset, oil and gas reserves, is accumulated through highly risky exploration activities. In contrast, integrated oil and gas companies display lower...

Aim: Propose a Data Envelopment Analysis (DEA) based approach to set energy efficiency targets under the Perform, Achieve and Trade (PAT) framework of the Bureau of Energy Efficiency (BEE) Design / Research methods: We adopt input-oriented non-controllable DEA model with variable return to scale...

This study attempts to discover the nexus between crude oil price fluctuation after heavy oil upgrading and stock returns of petroleum companies in the U.S. Stock Exchange for the years 2008 to 2018. One of the methods of upgrading heavy crude oil is to extract asphaltene from crude oil....

Purpose: The aim of this paper is to examine investors' economic and social profiles in renewable energy sources with the help of widely used investment rating indicators, such as Net Present Value, Internal Grade of Performance and Profitability Index. Design/methodology/approach: The study...

Decisions on climate change and nuclear policies are likely to have major influences on the future evolution of the Swiss energy system. To understand the implications of selected future policy decisions, we analyse the development of the Swiss energy system with a bottom-up technology-rich...

The aim of this paper is to enunciate a new way to estimate levelized cost of electric energy (LCOE), considering emission of greenhouse gases cost, by taking the theoretical cost of avoiding pollution as the emission cost. In this way, it would be comparable LCOE from different sources of...

This paper aimed to evaluate the impact of the current EU energy crisis on Romania s policies to boost green energy as a solution to balance the national energy mix. Our methodological approach was a mixed one using both bibliometric analysis and qualitative analysis based on experts interview....
