Energy efficiency is emerging as a silent force behind economic resilience and environmental progress. Across industries, homes, and transport, smarter energy use has curbed demand growth, saving billions in costs while improving access to vital services. In many countries, such as Japan, the UK or the USA, efficiency gains have offset rising energy needs, proving that growth need not come at the expense of sustainability.

Beyond savings, the benefits ripple through society. Households—especially those on lower incomes—see reduced energy bills, while businesses gain a competitive edge through lower operating costs and improved productivity. In developing regions, efficient appliances can mean the difference between access and exclusion, enabling more families to afford modern comforts.

The impact extends to public health and job creation. Retrofitted homes and cleaner technologies reduce air pollution and respiratory illness, while energy efficiency investments support millions of jobs in construction, manufacturing, and services. These gains are particularly vital in vulnerable communities, where energy poverty and unemployment often intersect.

Crucially, energy efficiency is also a powerful climate tool. It has already prevented billions of tonnes of CO₂ emissions and can deliver a third of the reductions needed by 2030 to stay on track for net zero. As the world faces rising energy demand and climate pressures, this report makes one thing clear: doing more with less is not just wise—it’s essential.
