4. Key Factors for the Success
of Energy Efficiency
• Top Management Involvement
• Top/Senior Management visibly demonstrated their
interest and concern in energy saving achievement.
• Responsibility for energy use
• Those responsible for production i.e., production costs -
labour, materials and other costs – made responsible for
controlling energy costs. The user of energy should be
responsible for its control as well.
