本研究認為台灣隨著經濟的成長，邁向已開發國家之際，高齡化人口結構逐漸成為了影響能源使用量的關鍵因素，且台灣對進口自然資源依賴程度已達98%，在未來自然能源缺乏的環境下，了解家庭結構對家計能源使用量的變化是至關重要的，充分掌握高齡化與少子化的人口環境，並能制定有效率的能源政策。 本研究使用行政院主計處<家庭收支調查資料庫>，資料年份為西元2005至2017年，共計13年，資料範圍包含本島及離島地區擁有台灣國籍身份之家庭成員，主要變數為家庭結構之變數，包含家庭個成員年齡、性別、收入，藉此推估不同家庭成員在使用汽油及電能上的差異，此外更加入經濟戶長類型變數，主要為經濟戶長出生世代背景對家庭能源影響差異。;This study believes that with the economic growth of Taiwan and the development of the country, the aging population structure has gradually become a key factor affecting energy use, and Taiwan′s dependence on imported natural resources has reached 98%.
