The electrical grid is a network of power plants, transmission lines, and distribution systems that provide electricity to homes and businesses. It is the backbone of modern society, providing us with light, heat, and energy to run our appliances. The grid works by converting energy from sources like coal or solar into usable electricity, which can then be distributed across vast distances via high-voltage transmission lines. This system allows for the efficient use of resources while ensuring reliable access to power in all grid-connected areas. Over time, technological advances have allowed for an increase in efficiency and greater control over how we use our energy sources.
