Lifestyles are changing due to information technology and other socio-technological trends. We study the energy effects induced by lifestyle shifts via tradeoffs in time spent in performing activities. We use the American Time Use Survey to find changes in times performing different activities from 2003 to 2012. The results show that Americans are spending considerably more time at home (7.8 days more in 2012 compared with 2003). This increased home time is counterbalanced by decreased time spent traveling (1.2 days less in 2012 versus 2003) and in non-residential buildings (6.7 days less in 2012 versus 2003). Increased residential time is mainly due to increased work at home, video watching, and computer use. Decomposition analysis is then used to estimate effects on energy consumption, indicating that more time at home and less on travel and in non-residential buildings reduced national energy demand by 1,700 trillion BTU in 2012, 1.8% of the national total.

由于信息技术和其他社会技术趋势，生活方式正在发生变化。我们通过权衡进行活动所花费的时间来研究生活方式转变所引起的能量影响。我们使用《美国时间使用状况调查》来发现从2003年到2012年执行不同活动的时间的变化。结果表明，美国人在家里花费的时间要多得多（2012年比2003年增加了7.8天）。出行时间的减少（2012年与2003年相比减少了1.2天）和非住宅建筑物（2012年与2003年相比减少了6.7天）减少了返乡时间。居住时间增加的主要原因是在家工作，观看视频和使用计算机增加。然后使用分解分析来估算对能耗的影响，
