2.4.2 Sustainability Indicators Selection and Their Weightage
ОглавлениеThe social, environmental, and economic indicators are the three basic pillars of sustainability, although some technological and operational indicators have also been reviewed in the literature [36, 48, 58, 59]. The selection of sustainability indicators for the present study has been made with reference to studies [48, 53, 58]. Table 2.2 presents a summary of the selected indicators. Ten indicators have been selected comprised of three technological, two economic, two environmental, and three social types. The optimization preferences are assigned as maximum (max-m) or minimum (min-m). The indicator values of selected technologies with the range given in the brackets are presented in Table 2.3. The indicator’s values and range were estimated from substantial available literature [32, 35, 48, 60–83]. The present study assigned equal weightage to all indicators assuming that all indicators are equally important for sustainable development.
Table 2.2 Summary of selected indicators.
Indicators | Type | Unit | Optimization preference |
Efficiency (I1) | Technological | Percentage | max-m |
Response to peak demand (I2) | Technological | Qualitative (1-5) | max-m |
Capacity factor (I3) | Technological | Percentage | max-m |
LCOE (I4) | Economic | USD/KWh | min-m |
Service life (I5) | Economic | Years | max-m |
Land use (I6) | Environmental | m2/MWh | min-m |
GHG emissions (I7) | Environmental | g CO2-eq/KWh | min-m |
Social acceptance (I8) | Social | Qualitative (1-5) | max-m |
Social risks (I9) | Social | Qualitative (1-5) | min-m |
Environmental risks (I10) | Social | Qualitative (1-5) | min-m |
