This article employs a global computable general equilibrium economic model (GTAP-E-PowerS) to examine the impact on the world economy if households in every country self-supply power to meet 30–100% of residential demand, with subsequent monetary savings diverted to consuming more food. Results show the power generation sector reduces output levels by 14%–42% across various countries if households 100% self-supply. Coal mining sectors are adversely affected in numerous countries with contractions of 9%–28% ($6,086-$18,935 million) in the United States and 4%–13% ($2,505–$8,143 million) in Australia. Improved outcomes for the world environment are found with reductions of CO2e emission levels of 2.24%–7.38% (or 924–3,042 MtCO2 equivalent). The agriculture and food-processing sectors expand significantly in many countries but also cause major increases in land prices, particularly in land-scarce countries in Middle East, Europe, Japan, and Taiwan. Results also show the security of food and energy supply are improved along with environmental gains from lower emission levels. However, the energy sector is adversely affected and those countries with a heavy reliance on fossil fuel extraction and mining activities experience significant reductions in real GDP.

Keywords: Solar home system; rooftop solar photovoltaic (PV); GTAP-E-PowerS model; Sustainable Development Goal 1 (SDG1); SDG 7; SDG 13.

 About presenter (Brief profile)

Duy is currently a Senior Research Scientist in agricultural and applied energy economics at the Agriculture and Food Business Unit, CSIRO. He is also an Associate Professor at the Centre for Applied Energy Economics and Policy Research, Griffith University. Prior to these appointments, he worked internationally at the University of Bonn (Germany), Colorado State University (United States) and the University of New England (Australia).

Duy is a leading economist in the field of foresight modelling and is leading the economic modelling team at CSIRO. He is pursuing the development of a set of global computable general equilibrium and partial equilibrium models to study the impact of climate variability and related policies on agricultural, food and energy systems in Australia and internationally.

Duy is interested in investigating the sustainability implications of bioeconomic transformation on global land-use change, agricultural production, food security, energy security, emission levels and others. His work also covers studies related to climate change impacts on agriculture, food security and livelihoods, as well as climate change mitigation policies, particularly in Australia and developing countries. He is passionate about helping countries and regional households to better adapt to climate change and achieve more sustainable development.

Duy has published more than 30 research articles mainly in top-tier energy and environmental journals, such as Renewable and Sustainable Energy Reviews, Applied Energy, Energy Economics, Journal of Clean Production, Energy Policy, Journal of Environmental Management, Environmental Science and Policy, and others. Duy supported and mentored many junior researchers in these publications. Duy has also prepared several reports for the United Nations and Government Departments, including a chapter in the forthcoming 2023 Global Resources Outlook. He was awarded the Top 5 Early Career Achievers in Social Science in Australia by The Australian (The Australian National Magazine) given his prominent contributions to foresight modelling development, environmental policy and ‘Net Zero Mission’ studies in Australia, Vietnam, South Africa, South Korea, China, the US, and Europe. In 2022, he received the prestigious Vebleo Fellow award, in recognition for his prominence, leadership and impact in the fields of science, engineering, and technology; and outstanding and creative contributions to basic and applied scientific research.

About series

This seminar series is part of the E-PhD Program at National Economics University. It targets PhD students, early-career researchers, and senior faculty who find interested in doing research in the areas of economics, business, management, and other inter-disciplinary fields of social science. The series is a platform for the wider research community to exchange ideas, networks and collaborations.
