2.4.2 Sustainability Indicators Selection and Their Weightage

Оглавление

The 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
