The energy in current use mainly comes from the electricity for equipment and office spaces, accounting for almost 100% (99.99994%) of the total energy usage. The remaining small amount of energy is used for diesel, natural gas, and heavy oil from the regenerative thermal oxidizer (RTO). Due to the addition of production lines, research and development systems, and a new injection factory, the overall electricity demand of the organization has increased. However, we are also making efforts to reduce electricity consumption by replacing old equipment with energy-saving devices, resulting in a slight decrease in total energy consumption in 2022 compared to the previous year. If we calculate the energy intensity based on revenue per thousand New Taiwan Dollars, there is a 16.86% decrease in 2022 compared to the previous year, which demonstrates the Company's improvement in energy efficiency.

Our main focus for improvement will continue to be energysaving measures. We will reduce electricity consumption by renewing the manufacturing processes or production equipment. We also plan to use renewable energy such as solar power to diversify sources of energy and reduce energy consumption risks.
