Global electricity demand climbed to an estimated 2,267 TWh in 2023, while renewables capacity additions surged past oil and gas capacity growth that same year. At the system level, electricity still accounts for 27.4% of final energy consumption, yet industries tied to electricity use are also showing the efficiency pressure needed to meet Net Zero. Let’s connect the supply, demand, and policy signals that explain why the energy transition is accelerating in some places and stubbornly slow in others.
