The significant increase in the number of solar panels installed on a global scale contributed greatly to this, the numbers of which broke the previous record. Now, by 2030, renewables and energy produced in nuclear power plants should form 50% of the “pie” of electricity produced worldwide (compare to 42% in 2025).
Demand for energy, regardless of origin (including fossil fuels, for example), is expected to grow by more than 3.5% per year until the end of the decade.
The main factors are the use of electricity for industrial purposesgrowth in the electric carsgreater consumption of air conditioning and the expansion of data centers and AI. The growth in demand is particularly visible in emerging and developing economies… but the rest shine compared to previous years.
Putting the data into perspective, in a horizon up to 2030, the increase in demand for electricity should multiply the increase in demand for energy from all sources by 2.5.
The data is driven by expectation that developed economies will finally see growth in consumption, after 15 years of stagnation in this chapter. The IEA estimates that, by the end of the decade, the contribution of the latter will have a 20% weight in total demand.
