Grid electricity refers to the electrical power supplied through a network of transmission lines, substations, and transformers that connect power plants to homes and businesses. This system allows for the distribution of electricity generated from various sources, such as coal, natural gas, nuclear, and renewable energy like solar and wind. The electricity travels through the grid, which is managed by utility companies to ensure a stable supply. Consumers draw power from this grid, and their usage is measured by electric meters. The grid also enables the sharing of electricity between regions, helping to balance supply and demand effectively.
