The penetration of Variable Renewable Energies (VREs) in the electricity mix poses serious challenges in terms of management of the electrical grids, as the associated variability and non-dispatchability are in contrast with the requirement that the load be instantaneously equalized by the...

Der angestrebte Umbau der Energieversorgung wird die Rationalität des Stromsystems vollständig verändern, indem die fluktuierenden erneuerbaren Energien (FEE, das heißt Wind, Photovoltaik und große Teile der Laufwasserkraft) zu den prägenden Systemsäulen werden. Die FEE sollen sukzessive...

The intended transformation of the energy supply system will completely change the rationality of the electricity system by establishing the variable renewable energies (VRE, that is wind, photovoltaic and large parts of the run-of-the-river hydroelectricity) as its formative pillar. As they are...

China is appraised to have the world's largest exploitable reserves of shale gas, although several legal, regulatory, environmental and investment-related issues will likely restrain its scope. China's capacity to successfully face these hurdles and produce commercial shale gas will have a...

The twenty-first century must see a decarbonisation of electricity production to mitigate the flow of greenhouse gas emissions into the atmosphere. This paper presents an econometric analysis of the factors that motivate the use of renewable energy in electricity production using panel data from...

Wind and solar energy are often expected to fall victim to their own success: the higher their share in electricity production, the more their revenue on electricity markets (their “market value”) declines. While in conventional power systems, the market value may converge to zero, this...

In the context of 100% renewable electricity systems, prolonged periods with persistently scarce supply from wind and solar resources have received increasing academic and political attention. This article explores how such scarcity periods relate to energy storage requirements. To this end, we...
