Japan's energy consumption has increased significantly since the 1970s oil crisis, with the commercial sector's energy consumption nearly tripling, while the industrial sector's energy consumption has decreased by about 20%. The country's energy efficiency has improved by about 40% over the past 40 years, but further efforts are needed to reduce energy consumption, particularly in the commercial sector. The commercial sector's energy consumption per unit floor area has remained relatively flat in recent years, despite an increase in floor area. Breaking down the commercial sector into nine industries, the largest energy-consuming sectors are now offices, buildings, and wholesale and retail trade. Energy-saving efforts should focus on high-energy-consuming equipment, such as air conditioning and lighting in offices, and hot water and air conditioning in hospitals.
