If presented with a choice of staying with a fixed tariff or moving to a dynamic tariff, will consumers maintain the status quo, or opt for change? Read full article
In this report attention is paid to the laminated covering, replacing the conventional lead sheath with corrugated aluminium or copper sheath in HV cables. Various designs and related pros and cons for both copper and aluminium laminated coverings will be discussed. Finally international experience and observed trends will be listed, resulting in the conclusion that a long term view, in which the beneficial properties of copper play a part, is recommendable.

It’s easy for us to say we support renewable energy. But in practice, what is our willingness-to-pay (WTP) for it?
A key factor in whether a particular country or region is likely to reach its renewable energy objectives – such as the European Union’s goal to achieve a 20% overall share of renewable energy by 2020 – is how willing households are to migrate to its use from conventional energy.Read full article
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
