Vor mehr als einer halben Million Jahren lernten die Menschen das Feuer zu nutzen. Aus diesem epochalen historischen Schritt entwickelten sie den Nerv unserer heutigen Wirtschaft und Kultur: die Gewinnung von Energie aus Kohle, Erdöl und Erdgas. Die Folgen allen voran der Klimawandel...

Der Gründer des erfolgreichen Solartechnologie-Herstellers Solarworld hält ein engagiertes Plädoyer für ein fundamentales Umdenken in der Energie-und Industriepolitik mit Schwerpunkt Solarenergie. (Rolf Raschka)

Electricity shortage has become a major challenge to continued economic growth in Bangladesh. The country is growing in terms of GDP growth at a rate of 7% a year. Bangladesh is expected to move towards 23rd position globally by 2050 from its position 31 in 2014, in terms of GDP at purchasing...

The intermittency of the solar radiation is the big challenger for the management of electrical SMART GRID network. So the forecasting of the solar radiation remains the crucial objective to anticipate the injection of the electrical power produced by a photovoltaic generator. In this study, we...

The growth in energy demand and global concern about the environment has resulted in the drive towards alternative energy sources and consequently this research concerning solar energy harvesting of radiation received at the earth's surface. Analysis of solar radiation data is an important tool...

The paper aims at analysing the energy performance of an innovative multi-source energy system for residential small-scale combined heat and power (CHP) applications. The integrated system is based on an Organic Rankine Cycle (ORC) fuelled by biodiesel, a wind turbine, and a photovoltaic unit....

Solar energy market is still growing in Morocco and in other countries ar,ound the world. The development and deployment of any solar project require a prefeasibility study before the establishment of the plant. The most important parameters influencing the site selection or the project...

In this paper, a reliable and cost-effective polygeneration system for an existing test building, able to provide electricity, cooling and heating needs is presented, modelled and assessed. The system relies on solar energy as the primary source (PV and solar thermal collectors). Building...

Qatari policymakers must balance domestic energy needs with the economic imperative to maximise hydrocarbon exports. We have modelled the optimal evolution of Qatar's electricity system over the next few decades, with the goal of quantifying the potential for solar energy (and other low-carbon...

Curtailment of variable renewable energy increases the Levelized Cost of Energy (LCOE), which is the tool often used to compare its profitability against traditional energy sources. Recently, the Kyushu Region of Japan had to curtail some of its solar production to meet energy balance. As many...
