2008-10-16 possible if energy-ef fi ciency measures are included in adaptations and renovations, and if most new houses after 2015 are built as passive houses . The increase in effi ciency is estimated to be 2%/year from 2010, but only 5% in total for 2000-2010. For the new EU countries, an increase in effi ciency of 57% is also expected for space heating,

2017-8-15 industrial applications, combined heat and power has the most energy-saving potential. This process uses the waste heat that is produced when fuel is converted to electricity for water heating, space heating, or industrial processes. Although burning fuel for electricity is only 30 percent effi cient, combined heat and power can be 50 to 80 percent

2000-9-1 High waste transport costs and low pollution leads to the conclusion that plants based on these technologies can be acceptably located within cities. This not only reduces the electrical distribution losses but also permits the ‘waste’ heat to be used in the plant locality resulting in overall CHP efficiencies greater than 80%.
