Abstract
Since 2014, Taiwan has promoted a 1% annual electricity saving target to promote electrical efficiency efforts. As the industrial sector accounts for approximately 60% of the overall electricity consumption of Taiwan, this sector presents the greatest opportunity for improving Taiwan’s overall energy efficiency. Here, the energy audit data of industrial energy users are analyzed via logistic regression to understand the factors impacting their likelihood of achieving the targeted 1% electricity saving. Of the variables under study, the number of employees and the rank of the energy administrator were significantly correlated with the likelihood of reaching the electricity saving target. Within the management structure of the factory, energy users with higher-ranking energy administrators are more likely to achieve the targeted 1% electricity saving. As it is impractical to rapidly increase the number of employees, higher-ranking employees, i.e., factory executives, should be appointed as energy administrators to improve users’ electrical efficiency and thus reach the targeted 1% annual electricity saving. Based on the findings of our research, we put forward a point of view that in addition to the introduction of new technologies to improve energy efficiency, it can also be achieved through adjustments to the management structure of energy administration.
Highlights
Taiwan is an island that is located on a seismic area and lacks self-generated energy
Energy users were analyzed based on two aspects: (i) the energy usage, i.e., the electricity consumption and contract capacity, and (ii) the scale and management structure of the factory, such as the number of employees and the rank of the energy administrator
A binary logistic regression was first conducted for the 2392 energy users studied to understand the factors that affect energy users’ ability to achieve the energy savings target
Summary
Taiwan is an island that is located on a seismic area and lacks self-generated energy. The Taiwanese government is currently promoting a nuclear power plant abolition policy. 98% of its energy use relies on imports, according to the Bureau of Energy [1]. Drastic changes to the energy supply are difficult to implement because energy structure cannot be adjusted in a short time. To reduce energy consumption, efforts must be made by the Taiwanese government to reduce demand and improve energy efficiency. The industrial sector accounts for the highest proportion (50%) of energy use among all sectors and represents the greatest opportunity for improvement
