Nowadays most of the decisions in the field of energy supply lead to an increased use of renewable energy resources. Such decisions imply several consequences for instance in electrical power generation. Indeed, replacing conventional energy sources by mor ...

District energy systems could be used together with centralized and decentralized energy conversion technologies in order to reduce the amount of CO2 emissions. One way to transfer the produced energy from these technologies to users is to implement the co ...

In order to pave the way to a sustainable energy future based on a large share of Distributed Generation (DG), there is a clear need to prepare the European electricity system for the large-scale integration of both renewable and other distributed energy s ...
Energy efficiency is one of the more economically sounds way to sustainability. Real Estate accounts for 30% of energy consumption in most developed countries. It also accounts for more than 30% of GHG emission. In the last several years many research have ...
This paper discusses the role of actors in the transition towards an energy self- sufficient region in Güssing, Austria. Regions with the vision of energy self-sufficiency are often called “energy regions”. We identify and describe the states, phases and m ...
The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...
Even if supercapacitors present a reduced energy density, they allow to store a significant amount of energy which leads to a significant autonomy for applications with reduced energy needs. The main advantage of supercapacitors is to compensate a limited ...
An innovative subway has been proposed using supercapacitors as energy source. In this paper, are presented different possibilities to reduce on-board stored energy in order to downsize the on-board energy storage subsystem. Special attention is paid to th ...
In the present context of finding ways to decrease CO2 emissions linked with human activity, district energy systems including polygeneration energy conversion technologies are likely to play a major role. District energy systems meet the heating, hot wate ...
Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
