Summary/Abstract

Accelerating development in Sub-Saharan Africa will require massive expansion of access to electricity-currently reaching only about one third of households. This paper explores how essential economic development might be reconciled with the need to keep carbon emissions in check. We develop a geographically explicit framework and use spatial modeling and cost estimates from recent engineering studies to determine where stand-alone renewable energy generation is a cost effective alternative to centralized grid supply. Our results suggest that decentralized renewable energy will likely play an important role in expanding rural energy access. However, it will be the lowest cost option for a minority of households in Africa, even when likely cost reductions over the next 20 years are considered. Decentralized renewables are competitive mostly in remote and rural areas, while grid connected supply dominates denser areas where the majority of households reside. These findings underscore the need to decarbonize the fuel mix for centralized power generation as it expands in Africa.

Summary/Abstract

Since economic reforms began in 1978, China's urban population has increased by half a billion. Over the next 20 years, cities will likely add another 300 million people through local population growth, migration and the integration of nearby rural areas. Cities account for the majority of resource use and pollution so achieving greener growth will depend on developing and implementing a more sustainable urbanization model. China's leaders have responded to these challenges with ambitious goals and comprehensive environmental laws and regulations. These have so far not significantly reduced the harm from air, water and soil pollution: in large measure because China's green governance does not match its green ambitions. Drawing on the World Bank's work on green growth and a recent joint urbanization study by the Development Research Center of China's State Council and the World Bank, this paper reviews recent academic research on green governance in urban China and discusses its main implications in the context of emerging global green growth concepts.
