Electricity demand increased by more than 3% annually from 2015 to 2025, expanding nearly twice as fast as overall global energy demand. The fuel serves as the primary energy source for high-value economic sectors generating more than 45% of global gross domestic product, despite meeting just 23% of total final energy consumption today.
Policymakers and industry leaders are weighing an ambitious target to raise this share of final energy consumption to 35% by 2035, an objective championed by the COP31 Presidency. Achieving this transition requires scrutinizing structural barriers, evaluating grid readiness, and navigating the changing nature of geopolitical energy security risks.
Current technology costs and energy prices suggest it is economically viable to elevate global electrification rates to approximately 33% immediately. The transport sector offers the most apparent commercial viability, heavily influenced by a 90% reduction in lithium-ion battery prices since 2010. Under current economic conditions, about half of all oil-based road transport demand can be competitively electrified. Electric vehicles already displace around 2.3 million barrels of oil demand daily. The buildings sector also presents vast opportunities, as half of the global space heating demand could be transitioned to electric technologies cost-effectively. Heat pumps offer substantial efficiency gains over natural gas boilers, enabling overall natural gas demand reductions even if the marginal electricity generation relies entirely on natural gas.
Executing this systemic shift poses distinct challenges regarding infrastructure and supply chains. Modernizing and expanding electricity grids must occur 40% faster over the next decade than it did during the 2015 to 2025 period to prevent severe connection delays and grid congestion. Hitting a 35% electrification rate pushes annual electricity demand growth to 1,400 terawatt-hours, doubling the pace of the previous decade. If low-emissions electricity generation expands only at the rate dictated by current policies, it will merely cover this additional demand, resulting in minimal aggregate power sector emissions reductions. To manage the variability of renewable generation and integrate new load dynamically, stationary battery storage must scale exponentially. Net zero models indicate that global battery storage capacity needs to increase nearly tenfold to reach approximately 2,900 gigawatts by 2035.
Accelerated electrification fundamentally alters global energy security dynamics. A high electrification trajectory could reduce energy import bills for fuel-importing nations by $400 billion per year by 2035 compared to 2025 figures. Factoring in the elevated energy prices observed in 2026, these projected annual savings exceed $500 billion. Global oil demand displaced by electric vehicles would reach 18 million barrels per day by 2035 in a high electrification scenario. However, reducing dependence on fossil fuel imports simultaneously creates new vulnerabilities related to critical mineral supply chains. The manufacturing of batteries, solar photovoltaics, and electric motors is characterized by high geographical concentration. While supply chain disruptions for these technologies would not paralyze installed operational capacity in the same manner as a halt in fuel shipments, the growing reliance on digitalized and interconnected energy assets introduces acute cybersecurity risks.
Global aggregate targets often mask deep regional disparities and underlying feasibility gaps. Advanced economies and China account for three-quarters of the global car fleet and the majority of heating demand, making them prime candidates for rapid commercial technology adoption. In stark contrast, 730 million people remain without basic electricity access. Total per capita electricity consumption in sub-Saharan Africa stagnates at 200 kilowatt-hours per year, representing a fraction of the 7,000 kilowatt-hours consumed per capita in advanced economies and China. Furthermore, current policy settings only put the world on track for a 30% global electrification rate by 2035, falling significantly short of the proposed 35% target. Bridging this gap requires raising annual end-use electrification investments to $1 trillion by 2035. It also necessitates comprehensive national strategies that shift focus from fragmented technology subsidies to cohesive infrastructure planning, ensuring energy affordability without jeopardizing long-term system reliability.
