Summary: Decarbonizing the electricity system to zero-carbon emission is crucial for climate change mitigation, but this transition may lead to increased costs in the U.S. electric power sector. This study presents a regionally resolved model to quantify the cost of decarbonizing the U.S. electricity system and finds that reaching zero CO2 emission by 2050 would incur an additional cost of 335-494 billion USD, depending on different scenarios. Regional costs of electricity generation vary due to generation profiles and renewable resource availability. Furthermore, the cost of mitigating the last few percent CO2 emission may exceed the costs of negative emission technologies, indicating an opportunity for their contribution to electricity decarbonization.

Summary: The paper examines the compatibility of wind and solar energy resources with projections of future electricity demand in Hungary. By modeling the national electricity system and estimating surplus generation, the study suggests that wind turbines and solar PV technology can supply 46-47% of the projected electricity consumption in 2033 with a surplus of less than 5% of yearly consumption. A suitable capacity ratio of wind to solar PV and the management of electric vehicle charging may reduce surplus electricity. It is shown by our EnergyPLAN model that the solar PV capacity should be 1.1 times the wind power capacity, which contrasts with the current situation in Hungary where solar PV is almost 10 times the wind power capacity.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.
