The long debate as to whether PV produces more energy than it consumes has been settled conclusively. It does.
A high energy return on energy investment (EROI) of an energy production process is crucial to its long-term viability. The EROI of conventional thermal electricity from fossil fuels has traditionally been viewed as being much higher than the EROI of renewable energy, and specifically of photovoltaics (PVs).Read full article
Over the years, the demand for flexible and functional electrical installations for houses and apartments has grown on a daily basis. Changing living conditions and habits, evolving housing needs, the availability of new technologies and the awareness of the importance of efficient energy use provide the impetus for an in-depth analysis of the electrical installation.Read full article
Today, most newly built or renovated private houses are still equipped with a rather simple electricity installation, providing not much more than a series of light points, switches and power outlets throughout the building. While this so-called base case electricity installation is very robust and safe, it is being challenged by the ever increasing expectations of 21st century homeowners and occupants.Read full article
A study conducted among distribution utilities throughout the world as to the grounds for deciding to use copper or aluminium conductors in LV and MV cable networks has highlighted the technical advantages of copper against the price advantage of aluminium.Read full article

It provides a technical guide to the different PV systems available.
It analyses different types of commercial consumers, with different consumption patterns and load curves.
It carries out an economic analysis to study the profitability of the investment in a PV generation system for self-consumption purposes at a commercial level.
The nuclear energy and renewable energy industries may be uncomfortable bed-fellows, but a hybrid energy system incorporating the best of both might draw them closer together.
Post-Fukushima, the jury is still out as to whether the nuclear industry has a viable future, with Germany and Italy already leading the retreat, and recommendations still in the process of being implemented to enhance reactor safety at existing plants worldwide.Read full article
The IEA Photovoltaic Power Systems Programme (PVPS) is one of the collaborative R&D Agreements established within the IEA and, since its establishment in 1993, the PVPS participants have been conducting a variety of joint projects in the application of photovoltaic conversion of solar energy into electricity.Read full article
