The urgency for new energy sources due to environmental degradation prompts a reevaluation of energy storage. Traditional lithium-ion technology faces criticism, leading the construction industry to propose innovative solutions. Bricks, cement, and minerals integral to construction become contenders for Thermal Energy Storage (TES) systems, transforming buildings into thermal batteries. 

High-rise buildings explore Lift Energy Storage Technology (LEST) in elevators, offering a cost-effective means to store energy. Single-family homes adopt dedicated battery systems, contributing to a 200% surge in the US installations between 2014-2018. Electrified cement emerges, acting as a supercapacitor. Also, sand batteries and grid-interactive buildings present scalable alternatives for decentralised, resilient energy infrastructure.
