For many living in Michigan, Thursday, August 14, 2003 was the day we truly experienced the “inky blackness” of a night without artificial outdoor lighting - as the Great Northeast Power Blackout of 2003 left parts of the northeastern United States in the dark for a day or more.
The Zoning Guru was one of those people who learned that week how much we rely on artificial light at night. We also got a brief glimpse of many stars that we no longer see in the night sky due to light pollution from parking lot lighting and other exterior light sources.
Exterior lighting serves a wide variety of purposes, including:
- attracting attention (advertising),
- entertainment,
- aesthetics (such as landscape or architectural lighting),
- safety and security,
- warnings of danger, and
- illuminating our paths.
When overused or poorly shielded, however, such lighting dominates the night sky, blotting out the starts and leaving the characteristically orange glow of light pollution over urban areas.
Can we do anything about light pollution? …absolutely. Do we need to cut the power again? No, but we do need to make smarter and more efficient decisions with regards to our exterior lighting choices if we want to restore the night sky in our urban and suburban neighborhoods… (more on this and an upcoming free lighting presentation on March 10th below)
