By applying the multiregional socially extended input–output (MRSEIO) framework, the authors evaluated human rights risks of 12 power sources in the UK as a case study. Results show that human rights violation risks for renewable electricity, such as solar and wind power, are 4–22 times greater than the electricity from gas per 1 USD of cradle-to-gate production. This almost counter-intuitive results might be attributed to the higher cost percentage in the construction sector, which has inherently hazardous characteristics. Furthermore, renewable power sources like solar PV (photovoltaics) would also be affected by potential forced labor in high-risk regions due to its unique supply chain. Notwithstanding limitations, the authors believe that this framework would enable a more quantitative discussion on the social aspects of the power sector, contributing to policymaking that considers not only environmental aspects but also human rights risks in the construction of future energy supply chain.
