How much does the US spend annually on outdoor lighting?

The answer of $3.3 billion reflects the estimated annual expenditure in the United States on outdoor lighting. This figure encompasses various costs associated with the installation, maintenance, and operation of outdoor lighting systems, which include streetlights, commercial lighting, and municipal lighting installations.

Understanding this amount is important, as it highlights the significant investment that municipalities and businesses make in outdoor lighting for safety, visibility, and aesthetic purposes. The expenditure also provides insights into energy consumption, sustainability initiatives, and the potential for cost savings through the adoption of more efficient lighting technologies. The other options would not accurately represent the comprehensive financial commitment involved in outdoor lighting within the country, as they underestimate the true scale of spending in this area.
