Since 2020 annual energy investment has increased by 45%

Energy efficiency, which measures useful output per unit of energy input, plays a crucial role in energy management by reducing costs and lowering greenhouse gas emissions. Efficiency improvements can be made across the energy system, from generation to home appliances and transport vehicles, and are often the most cost-effective way to enhance energy security and system reliability.

Energy management is essential for businesses, focusing on assessing energy use and implementing efficiency programmes. Innovative technologies in heating, lighting, insulation, small-scale power generation, and smart flexibility present numerous opportunities for better energy use. Energy managers, sustainability consultants, and facilities managers drive these advancements, ensuring compliance with increasing legal energy and carbon reporting requirements. They tackle challenges by leveraging supply, efficiency, generation, demand management, and behaviour change, aiming for a global low carbon, efficient energy system.
