Global Energy Demand Reaches New High as Renewables Scale Faster Than Fossil Fuels

Global energy demand reached a new record high last year, as rising electricity use, industrial activity and regional energy security priorities continued to reshape the global energy system. The latest Statistical Review of World Energy, published by the Energy Institute in partnership with Ember and in collaboration with Kearney and KPMG, found that total energy supply rose by 1.7%, with all major energy sources reaching all-time highs for the second consecutive year.

The headline finding is a mixed signal for the energy transition. Renewables accounted for the largest share of new energy supply growth for the first time outside a recession, with solar power responsible for most of the increase in renewable generation. At the same time, oil, gas and coal continued to grow, meaning the world is still adding clean energy on top of a large and persistent fossil fuel base rather than fully replacing it.

For businesses, policymakers and investors, the report highlights a central tension in the net-zero transition: clean technologies are scaling rapidly, but global energy demand is still rising fast enough to keep fossil fuel consumption and emissions under pressure. The shift to low-carbon energy is no longer marginal, but deployment alone is not yet delivering a rapid decline in fossil fuel use.

Electricity Demand Becomes a Central Pressure Point

Electricity demand is becoming one of the clearest indicators of this new phase. According to Sustainability Online’s summary of the report, global electricity consumption rose by 3% last year, while China’s electricity demand increased by 5%, more than any other major economy. China’s additional electricity use was equivalent to the entire annual consumption of Germany, illustrating the scale at which large emerging economies are shaping the global energy balance.

The rise in electricity demand reflects several structural trends. Industrial electrification, air conditioning, electric vehicles, data centres, artificial intelligence infrastructure and digital services are all increasing the need for reliable power. As more economic activity moves onto power systems, electricity is becoming not only a decarbonization tool but also a major source of new infrastructure pressure.

This is particularly important for net zero planning. Electrification can cut emissions when power systems are increasingly supplied by renewables, nuclear, hydropower and other low-carbon sources. However, if electricity demand grows faster than clean power capacity, fossil fuel generation can remain in the system for longer, especially during peak demand periods or when grids lack storage and flexibility.

Solar and Batteries Show Rapid Momentum

The growth of solar and storage remains one of the most significant developments in the report. Sustainability Online reported that solar generation expanded by 30% globally during the year, while installed battery storage capacity increased by 66%. These figures point to a faster buildout of technologies needed to integrate variable renewable power and reduce reliance on fossil generation during periods of high demand or low renewable output.

Solar power has become one of the most scalable parts of the global energy transition because of falling technology costs, shorter project timelines and broad deployment across utility-scale, commercial and residential markets. Battery storage is increasingly important because it allows more renewable power to be used when it is needed, rather than only when it is generated.

This matters for grids as much as for generation. Higher shares of solar and wind require investment in transmission, distribution networks, storage, demand flexibility and market design. Without those supporting systems, renewable deployment can face curtailment, connection delays and lower economic value. For companies buying renewable power, the next stage of decarbonization will increasingly depend on the quality, location and timing of electricity supply, not only annual procurement volumes.

Fossil Fuel Use Remains Difficult to Displace

Despite strong renewable growth, fossil fuels continued to reach record levels. This remains one of the most important findings for climate policy and corporate net-zero strategies. The global energy system is not yet moving from fossil fuels to clean energy at the speed required to place emissions on a steep downward path.

The challenge is not only the scale of fossil fuel infrastructure already in place. It is also the speed at which global energy demand continues to expand. When demand rises year after year, new clean energy capacity must first meet additional demand before it can significantly reduce the use of existing fossil fuel assets. This creates a substitution problem: renewables are growing quickly, but not always fast enough to push fossil fuels out of the system.

For industry, this means emissions reduction plans cannot rely only on the assumption that grids will decarbonize automatically. Companies with energy-intensive operations will need to combine renewable electricity procurement with efficiency measures, electrification, process redesign, heat decarbonization, storage, demand response and, where relevant, low-carbon fuels.

Regional Patterns Show Different Transition Pressures

The report also points to sharp regional differences. The United States saw emissions rise by 3.2%, driven by a 13% increase in coal-fired power, according to Sustainability Online’s account of the Energy Institute findings. In absolute terms, that increase was reported as four times larger than China’s emissions growth. China’s emissions rose by 0.3%, while India’s increased by 0.9%.

These regional patterns are important for interpreting global climate progress. Advanced economies may be expanding renewables and electrification, but short-term changes in weather, gas prices, coal availability, industrial activity and power demand can still push emissions higher. Emerging economies, meanwhile, are often balancing energy access, industrial growth, affordability and climate goals at the same time.

China remains central to the global picture because of the size of its electricity system, industrial base and clean technology supply chains. India’s growth reflects rising development needs and expanding power demand. The United States shows how fossil fuel generation can rebound when market or system conditions shift. Together, these examples show that the transition is not moving at the same pace everywhere.

Energy Security Remains a Major Factor

Energy security is another major theme. The report noted that oil production in the Americas increased by 4.8%, with the region now producing around 20% more oil than the Middle East. This shift reflects how energy geopolitics is changing alongside the clean energy transition.

Countries are pursuing renewable energy for climate and industrial policy reasons, but many are also reinforcing domestic or regional fossil fuel supply to manage price volatility and security risks. The result is a more complex transition environment, where clean energy expansion and fossil fuel security strategies often move in parallel.

For policymakers, this creates difficult choices. Short-term energy security can support economic stability and reduce exposure to external shocks. However, new fossil fuel investment can also increase the risk of long-lived emissions, stranded assets and slower progress toward climate targets. The balance between security, affordability and decarbonization is becoming one of the defining policy challenges of the decade.

Implications for Companies and Investors

For net zero strategies, the practical implication is clear: emissions reductions will require faster substitution, not just faster addition. Solar, wind, batteries and low-carbon electricity are expanding at record pace, but continued growth in total energy demand can dilute their climate impact if fossil energy also keeps rising.

This is particularly relevant for sectors such as heavy industry, transport, buildings and data infrastructure, where demand growth can quickly offset efficiency gains. Companies in these sectors face increasing pressure to show how their decarbonization plans will work under real energy system conditions, including grid constraints, regional power mixes and the availability of low-carbon fuels.

Investors are also likely to pay closer attention to the difference between transition exposure and transition delivery. Businesses may benefit from renewable energy growth, grid investment, battery deployment and electrification, but they may also face higher costs if power systems become more constrained or carbon-intensive than expected. Energy data is therefore becoming an important part of climate risk assessment.

A Transition Moving Forward, but not Fast Enough

The report’s findings show that the energy transition is increasingly visible in real-world data. Renewables are taking a larger share of growth, electricity is becoming more central to the economy, and storage is expanding rapidly. These are important signs of structural change.

Yet record total energy demand and continued fossil fuel growth show that the transition is still incomplete. The world is not only building a new energy system. It is trying to do so while total demand continues to rise, energy security concerns remain high, and industrial development continues across major economies.

For governments and companies, the next phase will require a sharper focus on implementation. That means faster permitting, stronger grids, more storage, better energy efficiency, clearer clean power procurement, and policies that help clean energy replace fossil fuels rather than simply meet new demand.

The latest data therefore offers both progress and warning. Clean energy is scaling faster than before, but the global energy system remains far from aligned with a rapid emissions decline. The central task for the net zero transition is now to turn record renewable growth into measurable fossil fuel displacement.
