Summary: This study examines the impacts of three policies on the power sector in the Middle East and North Africa region: removal of fuel subsidies, enhanced cross-border electricity trade, and a cap on carbon dioxide emissions. The results show that removing subsidies to natural gas for power generation would save the region $26.3-$27.5 billion, while cross-border electricity trade would save $83.6-$90.9 billion. Implementing both policies would reduce CO2 emissions in the power sector by 10% and save a net cost of $111 billion. However, introducing carbon emission-constraining policy would increase power supply costs by $97 billion. The study also highlights the complementary nature of removing fossil fuel subsidies and expanding cross-border electricity trade in achieving climate change mitigation goals in the MENA region.

Summary: Given the separation between China's renewable energy supply and load areas, the transmission capacity across regions is limited, hindering the penetration of renewable energy. This is directly influenced by policies such as renewable portfolio standard (RPS) and feed-in tariff (FIT). A multi-objective optimization model was developed to assess the impacts of changes in RPS and FIT policies on transmission line layout. The study found that strengthening power transmission in certain directions and increasing the RPS target can lead to the construction of more transmission lines, while continuing the FIT subsidy beyond 2020 may decrease the demand for new line construction. Ultimately, high penetration of renewable energy in China can be achieved.

Summary: The Generation Expansion Planning (GEP) process in Brazil takes into account various factors and constraints, including technical, economic, environmental, and climatic aspects. This study introduces scenarios that penalize or limit greenhouse gas emissions into the investment decision model (MDI) used in Brazil, aiming to assess the impact of emission reduction objectives on the optimum expansion planning. The results show that adopting a monetary penalty for fossil fuel combustion of US$25.00/tCO(2eq) leads to the largest reduction in emissions, with a corresponding increase in the expansion of wind and biomass sources.

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.
