Study of the Possibility of Zero-Emission by Simulation of the Residential Energy Demand in 2050

Abstract

To achieve 1.5°C targets, we must realize zero-emission. This paper analyzed the possibility of zero-emission in the Japanese residential sector in 2050, using a bottom-up simulation model. We added three measures as follows: Improvement of energy efficiency, reduction of equipment number, and operation of macro-frame. By implementing these measures and installing solar cells, it is possible to realize zero-emission in 2050.However, most power generation deficiency days and power generation excess days occur on different seasons. Therefore, it is needed to transfer energy to other sectors or to develop an energy storage system able to store for a long time.
