While modern coal-fired power plants like in Lippendorf and Lünen provide relatively high electrical efficiencies, their overall fuel utilization remains limited. Combined heat and power plants close to town in Bautzen and Chemnitz are able to use more of the heat available from electricity generation.
The press manufacturer Schuler is working on new technologies to cut energy consumption in half at an automobile stamping plant. Achieving similar potential savings in overall car-body manufacturing has turned out to be more difficult.
Coal gasification is considered a key technology for the long-term switch to carbochemistry. The greenhouse gas carbon-dioxide will one day be entirely integrated in chemical products and fuels, according to the International Freiberg Conference on IGCC & XtL Technologies (IFC) in Leipzig.

Solar and wind power are naturally quite irregular in terms of production and supply to the grid. The Epex Spot power exchange has coped with these fluctuations in supply rather well over the last year and a half. 07/2011
The watery residue from bioethanol production used to be disposed of on farm fields. Verbio, a Leipzig-based bioethanol producer, is now using it in a new procedure to produce biomethane in natural-gas quality as well as organic fertilizer. The company has thus added two new, high-quality products to its portfolio while improving its greenhouse balance sheet. 12/2010
Scientists have presented a concept of how German energy supply can be wholly converted to renewable energy by the year 2050. It’s really a matter of political decision-making, said Wolfgang Eberhardt, managing director at the Helmholtz Center for Materials and Energy. 10/2010
German scientists have come up with a procedure for storing surplus wind and solar electricity as biomethane. The upgrading of biogas to natural-gas quality is making particular headway in Germany, Sweden and Switzerland. Yet the basic parameters still need to be set for the international transport and trade of biomethane. 04/2010
Russia never ratified the Energy Charter, the international legal framework for the energy industry. At the German-Russian Raw Materials Forum in Freiberg, Germany, Russian energy politician Valery Yazev announced meanwhile the “concept of a Global Energy Code”. 03/2010
Huge potential for energy savings could be unlocked in the US by 2020, concludes a report from McKinsey. But this will only happen if a ‘holistic approach’ is adopted – and investments of some $500 billion are made. The investment would quickly pay for itself. 12/2009
German industry could save twenty-five percent of its energy consumption by consistently applying existing efficiency technologies. While industry managers adopt a new way of thinking, scientists are working on the vision of a resource-efficient factory. 12/2009
In Germany, some 4,000 plants produce biogas which is used to generate electricity. The latest trend is for plants to convert biogas into biomethane, which is then fed into the gas grid. By 2020, some 6% of the gas that flows through the German grid must be from renewable sources. 07/2009
German gas providers coped remarkebly well with the supply disruption in January. They even managed to supply extra gas to hard-hit customers in Eastern Europe. Even so the companies are expanding their storage capabilities and looking for alternative supply routes. 02/2009
