[en] This article presents, along with data on the statistics concerning accidents involving electrical installations for the period 1995 - 2004, detailed descriptions of several serious accidents. The examples of accidents presented cover a range of installations and situations and are selected from the 88 instances reported in Switzerland in the year 2004. The statistics and the number of victims in various areas are commented on. Safety rules that should always be followed when doing work on electrical installations are listed

[en] Starting from a look back on the development of nuclear energy with its progresses and setbacks, the author summarizes the present situation. In the forecast, he comes to the conclusion that nuclear energy in a developed technology can make an essential and indisposable contribution to a sustainable development and is urgently needed for this.

[en] The future of our environmental and energy problems will be decided next century in today's developing countries, particularly in the large agglomerations of the Third World. It is unlikely that fossil fuels will to any great degree be replaced by renewable energy sources and/or nuclear energy. The excellent efficiency of thermal power plants now achieved in the industrial countries should as fast as possible also be realised in the developing countries, and the process of electrification there should be accelerated. The greatest obstacle to a rapid worldwide spread of efficient energy systems are the political imponderabilities in many developing countries. (orig.)

[en] When, at the turn of the century, public electric power supply facilities were created and in 1908, the electric power stations of the Swiss canton of Zurich (EKZ) were built, only a third of the communities in the Zurich area could boast about being the consumers of this new energy. But what did the first electrically powered devices and machines look like? This, and more, is presented in the ''electric power house'' in Burenwisen Glattfelden in the canton of Zurich. Besides a Kaplan turbine and a sample of the most interesting devices from the past and the present, the focus of the exhibition is on the presentation of the new and old sources of light. The EKZ are pleased to be able to present their ''electric power house'' to the public, providing a broad range of information on energy-related questions and the development of electric power supply.

[en] The treatment method to be applied consists of thermal decomposition and vitrification. The facility to be constructed at the Zwilag is a plasma-arc furnace, and planning activities are heading towards the final phase. There will be only this one facility for treating in only one process step solid, mixed wastes, liquid wastes, sludges, metals, and inorganic wastes, producing vitrified waste packages ready for ultimate storage as 200-l waste drums. The main features of the plasma-arc furnace are explained. (orig./HP)

[en] ELECTROBROC is a unique centre for information, documentation and experiments in the fields of energy and electric power. At the same time, it is a forum for all those who are interested in energy and related environmental aspects. Furthermore, ELECTROBROC is also a means of communication. (orig.)

[en] The expansion of nuclear energy by 3000 GWe by the year 2030 would represent a worldwide increase of 30% in the use of nuclear energy as a primary energy source. Even this ambitious nuclear power programme could at least keep the annual CO₂ production constant. What are the short-, medium- and long term prospects of uranium reserves? Which technical measures and developments influence the range and potential of the nuclear electricity supply? In reference to the long term potential of nuclear energy past the year 2000, the basic question is how large the world uranium reserves are, and how reliable the indicators to these deposits are.

[en] Two events at the 16th World Energy Congress focussed on the subject of mobility, which is a determining factor of worldwide mineral oil consumption. The study 'Global transport sector energy demand towards 2020', written by a working group led by the Norwegian Statoil company, served as a basis for the debates. (orig.)

[en] Demand-side management and least-cost planning are terms one increasingly comes across in energy economy literature. This RAVEL paper (rationelle Verwendung von elektrischer Energie- electric power conservation) is dedicated to throwing light on the often unclear meaning, origin, relevance and applicability of these terms.
