Why Do We Tolerate Gp

  1. 1. Why do we tolerate bad lighting? Written and researched by Marc Sandberg, Dark Sky Georgia
  2. 2. What is Light Pollution <ul><li>Glare – Obtrusive and inappropriately applied outdoor lighting generates glare. Glare is any light that is in your direct vision (why do most indoor lights have shades on them?). </li></ul><ul><li>Light Trespass – Light from a neighbor, business or roadway that spills onto your property, without your consent. </li></ul><ul><li>Energy Waste – Light shining outward and upward into the sky is wasted. This waste is estimated at costing Six Billion Dollars annually. </li></ul><ul><li>Environment – Lights at night confuse and harm animals and birds, and distresses trees. </li></ul><ul><li>Urban Sky Glow – This is what you see when you look at a city from a distance, a dome of light covering a large area of the sky and blocking your view of the stars. </li></ul>
  3. 3. Who We Are <ul><li>International Dark-Sky Organization – more than 11,000 members worldwide </li></ul><ul><li>Dark Sky Georgia – local section of the IDA, more than 50 members </li></ul><ul><li>Dedicated to stopping the adverse effects of LP, raising awareness of the problem of LP and educating the public about LP </li></ul>
  4. 4. The Villains Growing pot in the living room? Drive Thru Operating Room? Acorn in the trees?
  5. 5. What are the problem indicators? Sky Glow <ul><li>Facts: </li></ul><ul><li>Does your night sky look like the photo on the left or the photo on the right? </li></ul><ul><li>Skyglow is not an indication of progress. It only indicates poor administration. </li></ul>Night of Blackout – 60 second exposure Night after Blackout – 30 second exposure
  6. 6. Glare on Streets
  7. 7. Street Lights – Use Full Cutoff
  8. 8. Light Trespass <ul><li>Facts: The problem of trespass occurs in nearly every community! </li></ul><ul><li>Lighting only provides benefits to society when the light is controlled and the source of illumination is discrete. </li></ul>
  9. 9. What is occurring nationwide? <ul><li>General Electric now sells more FCO luminaires for streetlights than non-FCO’s </li></ul><ul><li>Hundreds of local municipalities and counties have adopted some form of Dark Sky ordinances </li></ul><ul><li>Greenhouse gasses are becoming front page news </li></ul>
  10. 10. What has been done locally? <ul><li>Several Georgia counties have adopted a Dark Sky Ordinance (Fulton, Cherokee) with more on the way </li></ul><ul><li>Example of Poor Lighting – new Acorn Luminaires in Chastain Park </li></ul><ul><li>Examples of Good Lighting – </li></ul><ul><ul><li>Atlantic Station, all FCO’s </li></ul></ul><ul><ul><li>Sandy Springs Business District, all FCO’s </li></ul></ul>
  11. 11. Where does Georgia Power fit into this? <ul><li>Vendor of majority of outdoor luminaires </li></ul><ul><li>Currently viewed as an outdoor lighting expert </li></ul><ul><li>Currently taking steps to be perceived as a “green” company (e.g., compact fluorescent bulbs) </li></ul><ul><li>Currently viewed as a major polluter </li></ul>
  12. 12. Challenges <ul><li>Public - Baby Boomers are aging, making Glare a major concern, more infill properties means increased light trespass </li></ul><ul><li>Press – skeptical of GP’s environmental record, construction of new plants </li></ul><ul><li>Local Governments – starting to pay attention to greenhouse gasses and economics (including power bills) </li></ul><ul><li>Environmental Groups – becoming aware of impact of LP on trees, mammals, and insects </li></ul>
  13. 13. Opportunity for Georgia Power <ul><li>Become an advocate of appropriate outdoor luminaires (offer only cutoff luminaires) </li></ul><ul><li>Start replacing broken and worn out luminaires with FCO </li></ul><ul><li>Stop selling and discourage use of Acorns </li></ul><ul><li>Advise consumers on good outdoor practices </li></ul><ul><ul><li>Long Island Power Authority does all of this </li></ul></ul>
  14. 14. Result if Georgia Power becomes a leader in the fight against Light Pollution <ul><li>Georgia Power manages the situation, not the reverse </li></ul><ul><li>Georgia Power becomes known as environmentally sensitive to Light Pollution </li></ul><ul><li>Creates evidence of actions taken to reduce demand, when applying for new plants </li></ul><ul><li>Over time, less glare, trespass, and sky glow due to elimination of bad luminaires </li></ul>
  15. 15. Next Steps? <ul><li>Convincing management of value in becoming leader in fight </li></ul><ul><li>Presentations to more senior group </li></ul><ul><li>Help with consumer materials </li></ul><ul><li>Expertise in LP issues </li></ul>
