Abstract

Over the past two decades, new technologies and behavioral shifts – such as electric vehicles, solar photovoltaics, and increased work-from-home practices – have reshaped residential electricity consumption and cost. However, their combined or synergistic impact on a household’s electricity cost remains unexplored. Leveraging data from the 2020 Residential Energy Consumption Survey, this study uses a structural equation model to unravel the extent to which the bundled adoption of EV-PV and stay-at-home decisions impact the total electricity cost of households. Results indicate that adopting both EVs and PV reduces electricity costs by 31% despite a 16% rise in consumption. When combined with stay-at-home practices, households still experience a 13% cost reduction, even with a 25% increase in electricity consumption. These findings suggest that financial savings are not merely a byproduct of adopting new technologies or behavioral changes but could serve as a key consideration for household contemplating engagement with multiple modern energy solutions simultaneously.

家庭节能的跨部门协同作用：电动汽车、太阳能光伏和远程工作的作用

在过去的二十年里，新技术和行为的转变——比如电动汽车、太阳能光伏发电和在家工作的增加——已经重塑了住宅用电和成本。然而，它们对家庭电力成本的综合或协同影响仍未得到探索。利用2020年住宅能源消费调查的数据，本研究使用结构方程模型来揭示电动汽车-光伏和居家决策捆绑采用对家庭总电力成本的影响程度。结果表明，同时采用电动汽车和光伏可以降低31%的电力成本，尽管耗电量增加了16%。如果结合在家的做法，即使电力消耗增加了25%，家庭仍然可以减少13%的成本。这些发现表明，经济节约不仅仅是采用新技术或行为改变的副产品，而且可以作为家庭考虑同时使用多种现代能源解决方案的关键考虑因素。

期刊介绍： Transportation Letters: The International Journal of Transportation Research is a quarterly journal that publishes high-quality peer-reviewed and mini-review papers as well as technical notes and book reviews on the state-of-the-art in transportation research. The focus of Transportation Letters is on analytical and empirical findings, methodological papers, and theoretical and conceptual insights across all areas of research. Review resource papers that merge descriptions of the state-of-the-art with innovative and new methodological, theoretical, and conceptual insights spanning all areas of transportation research are invited and of particular interest.
