政府補助與企業節能績效研究與分析

為因應國內外永續發展之情勢，與維持經濟成長的基本動能的條件下，臺灣以「京都議定書」為基礎訂定「永續能源政策」，以能源供給的「淨源」與能源需求的「節流」作為策略推動之方向；本研究為探討政策補助之推動是否有助於能源需求「節流」之影響，以經濟部能源局95-108年之節能績效保證專案示範推廣補助資料作為分析，藉由探討能源需求面投入之專案金額、政府政策補助經費、設備節能率及汰換設備後可節省之支出對節能減碳之影響程度。本文經實證分析顯示：投入之專案金額、政府補助經費以及可節省之支出與減碳量呈現正向相關，即表示此補助計畫之推動對於能源需求面之節流為顯著影響；而設備節能率對減碳量則呈現不顯著關係，考量節能率於此計畫中為要素條件，建議執行當局適度酌量節能率重要性。

Responding a global trend of sustainability development along with stable economy growth, based on series of Kyoto Protocol initiatives, Framework of Taiwan’s Sustainable Energy Policy” was approved in June 1997, aiming to provide clean energy and reduce energy consumption. The study will evaluate the significances to energy consumption reduction by government financial support such as incentives. The study will particularly investigate Taiwan Bureau of Energy’s ESPC (Energy Savings Performance Contract) Incentives data from 2006 to 2019. By comparing and analyzing incentive funds to their supported project values, scopes, and energy savings performances, ESPC incentive’s cost-effectiveness can be equated. Through the study, it is concluded that amount of granted ESPC incentive varies proportionally to quantity of energy saving or carbon emission; meaning that government financial supports play important roles promoting energy consumption reduction. However, project scope, such as equipment selection itself does not have significant cost-effectiveness to energy saving. It is recommended to government authority that energy consumption reduction percentages should be primary evaluated.
