Contextual analysis through five country-specific simulations determined that the economic and environmental sustainability of the NEWgenerator was highly dependent on the context in which it will be deployed. The per capita cost of the NEWgenerator with photovoltaic energy across the five countries was as low as 0.068 USD•cap -1 •d -1 in India and as high as 0.100 USD•cap -1 •d -1 in Senegal, with higher costs for the grid-tied configuration ranging from 0.090 to 0.114 USD•cap - 1 •d -1 . The differences in per capita costs from the general case highlights the importance of contextual parameters in the characterization of the costs and life cycle GHG emissions of the NEWgenerator. The use of global average values may overestimate costs when deployment with locally manufactured or produced technologies is possible. Further, sub-national variation may lead to additional variation that can best be captured by more detailed consideration of specific localities under consideration for technology deployment.
