A joint working paper from the International Renewable Energy Agency (IRENA) and the Copenhagen Centre on Energy Efficiency (C2E2) illuminates crucial synergies that can help to ensure a sustainable global energy future. The interplay between energy efficiency improvements and the deployment of renewable energy technologies is complex. If the respective potentials in these two fields are combined, total global energy demand can be reduced by up to a quarter by 2030, IRENA and C2E2 find. Energy efficiency measures would account for half to three-quarters of the total energy savings, with renewables delivering the rest. Demand reduction through renewables depends on adopting modern technologies, including efficient cook stoves that increase conversion efficiency 2-3 times, electrification equipment like geothermal or air heat pumps that deliver 3-4 times their power consumption in the form of heating or cooling, and power sources like solar and wind that require no thermal conversion and therefore waste no fuel. Quantitative analysis used data for eight countries – China, Denmark, France, Germany, India, Italy, the United Kingdom and the United States – covering half of global energy use.
