Since Taiwan lacks sufficient self-produced energy, increasing energy efficiency and energy savings are essential aspects of Taiwan’s energy policy. This work summarizes the energy savings implemented by 303 firms in Taiwan’s textile industry from the on-line Energy Declaration System in 2008. It was found that the total implemented energy savings amounted to 46,074ton of oil equivalent (TOE). The energy saving was equivalent to 94,614MWh of electricity, 23,686kl of fuel oil and 4887ton of fuel coal. It represented a potential reduction of 143,669ton in carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 3848ha plantation forest. This study summarizes energy-saving measures for energy users and identifies the areas for making energy saving to provide an energy efficiency baseline.
