When you look inside an AC locomotive, you may notice that there is a transformer in it. You may figure out that the rating of said transformer is ≈5 MVA, its efficiency is ≈95% and the mass ≈10 tons. A utility transformer of comparable rating (same frequency – the odd 16.7 Hz in Germany, Austria, Switzerland, Norway and Sweden) would have a mass of 50 t and an efficiency of 99%.

This paper analyses the effect of the novel market-based instrument of emission trading on investment strategies of local utilities in the climate friendly technologies of combined heat and power (CHP) and renewable energy resources (RES). We take the example of the German electricity sector, where the economic conditions have been subject to dramatic changes in recent years.

It may be normal that in a church an earthing electrode, if any, is directed to the sky, like this one found in Jena / Germany beneath the altar, and not linked to anything "earthly", but under "normal" conditions and from an electro-technical point of view, if there is any sort of electrical installation contained in any building at all, it should also be earthed!

The EU Directive 2006/32/EC on energy end-use efficiency and energy services (ESD) became effective on 17 May 2006. Now the Member States have to develop strategies and policies for the national implementation of the Directive, which sets a national indicative energy savings target of 9 % for the ninth year of the Directive’s application. This target is to be met using measures to improve energy efficiency. The Member States have to present their first energy efficiency action plan (EEAP) under the ESD by 30 June 2007, which must contain the national overall target for energy saving.

On the January 23, 2008 the European Commission agreed on a far-reaching package of proposals that will deliver the European Council's commitments to fight climate change and promote RE. With the publication of this Climate Action Plan and its several targets, the EU wants to show global leadership in this area.
This report provides an overview of the Kyoto-targets and the objectives of energy from RES in final energy consumption in 2020.
