Rising Of Global Electricity Demand: The Importance Of Industry And Renewable Energy Integration

This study investigates the rising global demand for electrical energy, its environmental consequences, and the potential of demand response (DR) strategies, renewable energy sources, and energy storage systems (ESS) to address these issues. Global electricity demand is projected to grow by 2.1% annually through 2040 and by 3.4% by 2026, driven primarily by industrial and construction sectors accounting for over 90% of the increase. However, traditional energy production significantly contributes to environmental degradation, responsible for 46% of global emissions in 2024. DR and ESS provide effective solutions by enabling flexible energy management, reducing peak loads, and facilitating renewable energy integration. The combined use of ESS and renewables can lower electricity costs by up to 17.9%, enhance grid stability, and reduce emissions. The study evaluates various ESS technologies, including lithium-ion batteries, pumped hydro storage (PHS), and compressed air energy storage (CAES), noting their benefits, such as high efficiency, and challenges, like high costs and technological limitations. While the industrial sector holds significant potential for DR, barriers such as process complexity and limited flexibility remain. ESS plays a pivotal role in modernizing electrical grids, supporting distributed energy systems, and advancing carbon neutrality through better integration with renewables and smart grid technologies. Future research should focus on optimizing these technologies to enhance energy efficiency and address climate change effectively.
