Table 4: _Cont._These different amounts of energy and material supply generate different environmental effects [33] that can be observed on the supply side and the sink side. When the FU (micro timescale) is used, there is only interest in the viability (technical and economic) of the CHP plant Table 4 (a), and less attention is paid to the changes in the feasibility assessment of the ecological resources.
