TL;DR: In this paper, the authors present a set of guiding principles for energy system optimization models (ESOMs) that can be used to guide ESOM-based analysis, including how to formulate research questions, set spatio-temporal boundaries, consider appropriate model features, conduct and refine the analysis, quantify uncertainty, and communicate insights.

TL;DR: In this paper, the authors investigated mitigation strategies beyond 2020 and the interplay between different decarbonization options, and found that wind power and bioenergy increase considerably beyond current deployment levels.

TL;DR: In this article, the authors developed state-of-the-art representations of consumer preferences in multiple global energy-economy models, specifically focusing on the non-financial preferences of individuals.

TL;DR: It is shown that removing fossil fuel subsidies would have an unexpectedly small impact on global energy demand and carbon dioxide emissions and would not increase renewable energy use by 2030, and subsidy removal would result in the largest CO2 emission reductions in high-income oil- and gas-exporting regions.

TL;DR: Contrary to the hopes of policymakers, fossil fuel subsidy removal would have only a small impact on global energy demand and carbon dioxide emissions and would not increase renewable energy use by 2030 as discussed by the authors.
