Multiple Benefits of Energy Efficiency for Business Quality and reputation
Greater efficiency can reduce defects and improve production quality Energy efficiency improvements often involve tighter control and optimisation of production processes. By improving precision and stability in how equipment operates, firms can reduce variability in output and limit the occurrence of defects. These effects are particularly important in manufacturing sectors where small deviations can affect product quality and increase waste.For example, an industrial bakery in Switzerland implemented a highly efficient centralised cooling system with CO₂-refrigerant and advanced controls. The system allowed for a more constant controlled temperature and reduced downtime, improving product quality and consistency, all while reducing…

Fatih Birol
Executive Director. As Executive Director of the International Energy Agency, Dr Fatih Birol (@fbirol) has positioned the IEA at the forefront of global efforts to advance a secure, affordable and sustainable energy system. Since taking office in 2015, he has modernised the Agency by broadening its energy security mandate beyond oil to include electricity, natural gas, renewables and critical minerals, strengthened the Agency's global leadership in clean energy transitions and expanded IEA membership to include major emerging countries. As a result, the IEA’s share of global energy demand coverage has increased from 40% to over 80%. He has also played a central role in the global response to major energy security emergencies, including those triggered by the invasion of Ukraine in 2022 and the 2026 Strait of Hormuz crisis.Dr Birol joined the IEA in 1995 and steadily rose through the ranks from junior analyst to Chief Economist, where he oversaw the flagship World Energy Outlook.
