A sustainable approach to the challenge of rising global


energy demand By Yannick Sel, Commercial Director of Projects, Sarens

ver the last few years, the energy generation system needed to make a major effort to cope with an ever-increasing demand. According to estimates by the International Energy Agency (IEA), this demand is expected to increase by 3.4 per cent by 2026. Countries such as China,


with a 5.1 per cent increase in consumption and India, which will increase its demand by 6 per cent by 2025, will be just some of the main players in this new energy trend. It is no coincidence that two of the countries that are putting


most effort into technological development are the locomotives driving energy demand. Behind much of this growth is the increase in the number of data centres needed to sustain the use of artificial intelligence around the world and other trends such as cryptocurrencies. Thus, it is estimated that data centres will be responsible for the consumption of more than 1000 TWh in 2026 compared to the 460 TWh they required in 2022. To have a clear reference of the dimension of this consumption, it would be approximately equivalent to the consumption of a country like Japan. In addition to this major trend, there is a further challenge; to


continue to reduce dependence on energy sources that have an environmental impact. If in 2023, electricity accounted for only 20 per cent of all energy consumption worldwide, it is necessary to continue promoting electrification as the main source of energy supply for the entire world, at least up to the target of 30 per cent in 2030, in order to meet the ambitious but necessary targets set by the IEA, which include achieving zero net emissions in 2050.


Wind energy as a pillar of sustainable growth in production Although many countries continue to rely on nuclear energy, a safe and clean alternative, the truth is that more and more countries
