Global energy demand is no longer moving in unison, as structural slowing in advanced economies clashes with resilient, feedstock-driven growth in the U.S. and emerging markets.
Global energy demand grew by approximately 1.3% in 2025, significantly below the historical decadal average of 2.0%. While the expansion of AI data centers spiked local power demand, increasing consumption by 17%, these gains were largely offset by structural efficiency improvements. According to the IEA Energy Efficiency 2026 report, global energy intensity improved by nearly 2%, as structural gains in residential and industrial efficiency acted as a massive brake on total growth. This led to a regional divide: advanced economies experienced contracting demand, while nearly all net global growth originated in emerging and developing markets.
Within this slowing system, oil demand has decoupled across regional lines. The U.S. emerged as a global outlier, with oil consumption rising by 170 kb/d (0.9%), while other advanced economies (EU, Japan, and Korea) saw a combined decline of 270 kb/d. This U.S. resilience is supported by rising consumption of petrochemical feedstocks, particularly LPG and ethane, which has balanced the ongoing structural decline in road transport fuels. Internationally, the narrative is defined by geography and fuel composition, while European and Japanese demand fades, markets in Southeast Asia and Africa remain growth-intensive.
While total energy demand slowed, global electricity demand grew by 3% to 4% in 2025, accounting for nearly all of the world's total energy growth. Solar PV was the largest contributor to new supply, meeting more than a quarter of the world’s additional energy needs. However, this expansion has only deepened the global dependency on natural gas.
The 60% growth in low-emission sources has not replaced natural gas. Instead, it has solidified gas-fired generation as the critical backstop required to manage renewable volatility. This was critical in 2025 as electricity consumption from data centers soared by 17%. When renewable output faltered during European wind droughts and hydro shortages in the Americas, gas-fired generation bridged the gap, preventing grid failures. For U.S. operators, natural gas is a scalable fuel that can provide the 24/7 reliability required by a digital economy.
Despite rapid renewable energy expansion, fossil fuels continue to grow as infrastructure, material, and capital realities reinforce their essential role.
Fossil fuels increased in 2025 due to persistent infrastructure constraints, material shortages, and capital realities, reinforcing their essential role. Fossil fuel consumption increased in 2025 due to persistent infrastructure constraints and the technical challenges of integrating intermittent resources. Furthermore, expansion remains tied to critical mineral supply chains (lithium, cobalt) and introduces geopolitical constraints. In 2026, that reliance is expected to be supported by a new wave of global LNG supply, providing scalable and dispatchable capacity that current grid and material limitations prevent renewables from fully replacing.
A deepening capital misalignment is reshaping the global energy landscape as investment flows increasingly detach from near-term system needs. In 2025, global energy investment reached a record $3.3 trillion, with clean energy attracting twice as much capital as fossil fuels, a ratio of $2.2 trillion to $1.1 trillion.
While this shift reflects long-term energy expansion priorities, oil and gas operators continue to support the 24/7 reliability that the global economy runs on. As competition intensifies, the industry’s focus on capital discipline and operational efficiency has solidified U.S. operators as a foundational pillar of global energy security.
Simultaneously, scaling the energy transition introduces complex economic and physical constraints. These supply chains are increasingly global and concentrated, reinforcing the geopolitical sensitivities highlighted by the IEA while raising ongoing questions about cost, timing, and scalability. Efforts to expand access to reliable, low-cost energy, while supporting industrialization, continue to shape energy choices across regions where fossil fuels remain closely tied to economic development. In these regions, such as India, Africa, and Southeast Asia, fossil fuels are likely to persist alongside growing clean energy adoption, as alternatives face high near-term costs and/or infrastructure barriers.
Amid global EV momentum surpassing 20 million units and thus a decrease in road fuel demand, the U.S. transportation sector faces a widening gap between transition ambition and market reality.
U.S. EV sales growth has decelerated to single digits due to high interest rates and a persistent affordability gap (a 30% price premium over combustion vehicles). Consequently, EVs are only marginally trimming road fuel demand. Meanwhile, overall U.S. electricity demand is surging, driven by data centers, straining grid decarbonization efforts. Policy implications for the transportation sector remain uncertain in the U.S. as the regulatory environment remains turbulent. The rollback of U.S. climate policies and an aggressive tariff posture are complicating OEM supply chains and limiting domestic capacity investments. Even after IEEPA tariffs were ruled unlawful, the Section 232 tariffs remain in place.
While increasing demand and renewable growth are primary topics in this report, the structural case for fossil fuels, specifically as a reliability backstop, has never been stronger. In 2025, global energy demand grew only 1.3% as efficiency gains and industrial slowdowns offset surging electricity needs. To capitalize on these shifts, the fossil fuel and transportation sectors should consider the following:
U.S. energy companies should avoid framing the IEA report as a win for one fuel type over another. The core message emphasizes that the energy system is becoming more electrified and reliant on flexible capacity. Fossil fuel demand is unlikely to disappear soon. Rather, the transition increasingly resembles an expansion.
The IEA’s 2026 data underscores a more complex energy landscape and suggests that the transition is evolving more as an expansion. Electricity demand is rising faster, data centers are significantly shaping U.S. load growth, renewable energy is expanding quickly, and fossil fuels continue to provide essential flexibility and reliability. For U.S. energy providers, the best approach is to invest in assets that can meet rising electricity demand, provide stable capacity, withstand market and policy fluctuations, and tap into resilient sectors such as gas, NGLs, petrochemicals, aviation, and grid-support infrastructure.
