Future electricity systems with tight constraints on carbon emissions will rely much more on wind and solar generation, with zero marginal cost, than today. We use capacity expansion modelling of Texas in 2050 to illustrate wholesale price distributions in future energy-only, carbon-constrained...

Constraints on electric power system carbon emissions will make optimal increased reliance on variable renewable energy (VRE, mainly wind and solar generation), which has near zero marginal operating costs. Using capacity expansion modeling of electric power systems in three US regions in...

The final version of this paper will appear as Chapter 6 in the forthcoming MIT Energy Initiative study, The Future of Storage. Chapters referred to in this paper will be included in that study when it is published. In order to illuminate the role of energy storage in future decarbonized...

This paper examines how digital finance development affects household risk sharing in China. We provide convincing evidence that households that experience idiosyncratic negative shocks on income growth exhibit a disproportionally lower level of reduction in idiosyncratic consumption growth in...
