The International Energy Agency’s (IEA) recently released Energy Efficiency 2025 report indicates that global electricity demand is experiencing sustained and robust growth, with demand for clean energy, power security and energy efficiency reaching unprecedented levels across all sectors. Photovoltaic storage, as a key technology for enhancing energy resilience, is also entering a broader window of opportunity for wider application.

I. Electricity Demand Enters Accelerated Growth Cycle: Fourfold Increase Over Past Half-Century

IEA data indicates that over the past fifty years, global electricity demand has quadrupled, far outpacing growth in all other energy types. By 2025, electricity accounted for 21.5% of final energy consumption, continuing to rise at an annual rate of approximately 0.5%.

China has witnessed particularly pronounced electrification: electricity accounted for merely 5% of China’s final energy consumption in the early 1980s, rising to approximately 30% today. Converging factors including industrial upgrading, smart manufacturing, the digital economy, and transport electrification have positioned China as the world’s foremost driver of electricity demand growth.

II. Industry, Buildings and Transport Remain Primary Energy Consumption Sectors

According to IEA data for 2024, global final energy consumption reached 425 EJ (1 EJ = 10¹⁸ joules), distributed as follows:

– Industry: 40%

– Buildings: 30%

– Transport: 30%

Between 2019 and 2024, global final energy consumption grew by an average of 5 EJ annually, with two-thirds of this increase originating from China. By sector, industry contributed approximately two-thirds of the new energy consumption, while buildings contributed 20%, reflecting how the scale of manufacturing and ongoing urbanisation continue to drive rapid expansion in overall energy demand.

Particularly within industry, global industrial electricity consumption reached 40 EJ in 2023, with 60% used in industrial motor systems. China, with its vast industrial base, has become the world’s largest consumer of industrial electricity, accounting for roughly half of global industrial motor electricity use.

Such substantial energy requirements necessitate stable, cost-effective, and resilient energy supply as critical operational imperatives for industry.

III. Evolving Energy Demands Drive Photovoltaic-Storage Integration as Essential Infrastructure

Against a backdrop of sustained energy consumption growth, electricity supply-demand imbalances intensify, presenting enterprises with universal challenges: escalating energy costs, peak-shaving pressures, and grid integration stability.

‘Photovoltaics + Energy Storage’ is evolving from an optional solution to an essential configuration across industrial, commercial, and building sectors, primarily manifested in:

1. Photovoltaics reduce energy costs, while energy storage enhances system value

Photovoltaics address high daytime electricity costs, whereas energy storage provides evening power supply, peak shaving, valley filling, and backup power, enabling ‘round-the-clock energy regulation’.

2. High-energy industries demand greater power stability

Industrial motors, automation equipment, factory lighting, and data systems all require stable, high-quality power support. Energy storage systems effectively mitigate grid fluctuations and provide UPS-level protection in critical scenarios.

3.Buildings and transportation emerge as new growth areas for PV+storage

From office buildings and industrial parks to charging points and car parks, national policy support for distributed PV+storage continues to strengthen, further expanding the demand-side foundation of the PV+storage market.
