General equilibrium impact evaluation of food top-up induced by households’ renewable power self-supply in 141 regions

• Outputs of electricity and fossil fuel mining sectors decrease in all countries. Positive impacts on agriculture food production occurs Land prices increase significantly land-scarce Real GDP reduces countries with less dependence agriculture. GHG emission levels marginally reduce various This article employs a global computable general equilibrium economic model (GTAP-E-PowerS) to examine the impact world economy if households every country self-supply power meet 30–100% residential demand, subsequent monetary savings diverted consuming more food. Results show generation sector output by 14%–42% across 100% self-supply. Coal are adversely affected numerous contractions 9%–28% ($6,086-$18,935 million) United States 4%–13% ($2,505–$8,143 Australia. Improved outcomes for environment found reductions CO 2 e 2.24%–7.38% (or 924–3,042 MtCO equivalent). The food-processing expand many but also cause major increases land prices, particularly Middle East, Europe, Japan, Taiwan. security energy supply improved along environmental gains from lower levels. However, is those heavy reliance extraction activities experience significant real GDP.
