“…In the energy sector, other import indicators for economic sustainability of electrification solutions are the cost-effectiveness (e.g., [19,22,39]) and the Table 1 Indicators for sustainability of off-grid PV systems in Chile (adapted from [15]) reliability of supply (see, e.g., [19,22,23,28,41,42]). Moreover, since energy consumption is correlated with income, efforts on rural electrification are expected to contribute to the income of its users (e.g., [19,39,[43][44][45]). However, if energy projects aim at a higher productive outcome of rural communities, electrification programs need to be coupled with complementary infrastructure, including training and education [45].…”
