For a better comprehension of the efﬁciency of compressed air conversion some simpliﬁcations have to be made. When air is deﬁned as an ideal gas (same gas constant) and the isothermal state change is described by: p1 V1 ¼ p2 V2 : ð2:6Þ V The resulting mechanical work W12 that is necessary to perform the demanded strain work of uniform tension can be derived as (Baehr and Kabelac 2009, p. 60): Z2 V ¼ À pdV ¼ Àp1 V1 lnðV2 =V1 Þ: W12 ð2:7Þ 1 The adiabatic and isentropic state change describes a pressure change without any heat flows entering or leaving the system more accurately, but still in an ideal approximation.
2) In his report to the Club of Rome, Randers forecasts that the global energy demand will rise by 50 % in the time span from 2012 to 2052. It is especially noticeable that he foresees the peak of the global energy demand in 2030 and a slow decline from thereon (Randers 2013, pp. 132–134). Randers’ prognosis is situated below the current policy scenario of the International Energy Agency (IEA), but is still above the desired 450 ppm of CO2-eq. scenario (later referred to as the 450 ppm scenario), proclaimed to be the one with the highest probability to ensure the maximum of 2 °C of global warming compared with pre-industrial levels in this century (IEA 2012, pp.
Technical processes like heating, cooling, lighting, production of goods, transportation and the transmission of data demand energy— moreover, effective work or electricity, which is exergy. To supply exergy to technical processes in factories, primary energy must be converted (Baehr and Kabelac 2009, pp. 2 Energy Types at the Factory Gate The conversion of primary energy sources from import, storage or extraction or from renewable sources into ﬁnal energy, supplied to the factory, is deﬁned as the energy chain (Cleveland and Morris 2009, p.
