Clean-energy utilization technology in the transformation of existing urban residences in China

Abstract Clean-energy substitution technology for existing residential buildings in cities is an inevitable choice sustainable development and low-carbon ecological city construction. In this paper, the current status of energy-saving renovation renewable-energy applications various China was summarized by using statistical methods. The geographical distribution clean-energy power generation primary energy production explored depth. According to different climatic divisions urban residences, consumption were analyzed predicted based on STIRPAT model. results show that 2016 increased 43.6% compared with 2009, percentage clean also from 7.9% 13.4%. Different regions have advantages regarding energy: nuclear leads region experiences hot summers warm winters, whereas wind solar lead cold severely regions. present provide basic data support planning implementation upgrading transformation systems residences China.
