Abstract
Transport is an essential part of human life. Encouraging behavioral changes toward a less car-dependent and energy-saving lifestyle is needed to understand whether people can make a better life without a car or not. In this regard, a life-oriented approach is important; however, impacts of a large set of life choices on energy consumption have remained unknown. This chapter makes an initial attempt to make use of the life-oriented approach to better understand household energy consumption by using a data from about 900 respondents living in different parts of Japan in 2014. Considering that Japan has the highest elderly ratio (about 28%) in the world, there are more elderly samples in the data. A random forest approach is applied to quantify the influences of 87 variables of life choices covering 10 life domains on household consumption of electricity, gas, kerosene, gasoline, and diesel. Various insights are derived for supporting energy-saving policies.
