Abstract

Mid- and long-term energy requirements and greenhouse gas emission scenarios for China were presented by using the Integrated Policy Assessment Model of China. Technologies are the key component to reach a low carbon future. Technologies are identified with the scenario analysis. In order to realize the low carbon future, a technology roadmap was presented to reach the emission reduction up to 2050 in China. Twenty-eight key technologies are given in the paper for the technology roadmap, presenting learning curves. With full adoption of these key technologies, we do see ample opportunities for China to make the emission stable after 2020, without a large increase, and even start to have a deep reduction after 2030.

Abstract

Bioenergy from crop residues is one of important components of clean energy to adapt climate change. However, it is still uncertain how bioenergy potential from crop residues changes, as well as what deficits exist when offsetting fossil energy consumption. Taking the Yangtze River Delta (YRD) in China as an instance, bioenergy potential of crop residue was estimated for the period 2001-2010. The deficits between bioenergy from crop residue and fossil energy consumption were assessed to examine their differences. We found that a large amount of cropland, approximately 15% of the total cropland in 2000, was encroached for other uses in this period. The cropland loss reduced the bioenergy of crop residues, at a rate of 4.05 x 1011kJ · year-1, approximately 1.62% of annual average bioenergy from crop residues. In this context, further research and policy are needed to advance sustainability in the YRD in future decades. [ABSTRACT FROM AUTHOR]
