Dimming Street Lights, Bright Idea

Prince George, B.C.- It’s called “adaptive street lighting”, street lights which power down when traffic is light, to reduce energy consumption.
 
The City of Prince George was among the first municipalities in North America to deploy adaptive street lighting technology .  Forty six Streetlight Intelligence Inc.’s (SLQ) Lumen IQ™ units (shown in photo at right) were deployed on a pilot basis in 2006.  Data from these units shows a 41% reduction  in energy consumption. According to B.C. Pacific Green if adaptive street lighting technology were deployed in all the City’s own street lights, energy consumption would be cut by 1,274 MWhrs and GHG emissions cut by up to 465 tonnes / year.
 
General Manager of Operations, Bob Radloff says there were no issues during the pilot project on issues of cold weather, vandalism,  snow, or unexpected costs.
 
Now, the City of Prince George is being asked to install 1425 of the special street lights.
 
According to the research, slowly reducing the energy supply to a street light by 40% or more cannot be detected by the human eye and creates no real reduction in lighting levels.
 
While the overall installation costs are in the $170 thousand dollar range, it is thought the City can recoup a lot of that money through the B.C. Hydro Power Smart incentive program.
 
The proponents of the project say the installation of the new lights could save the City about $34 thousand a year in energy costs, and reduce GHG by 207 tonnes a year.
 
City Council has requested the  idea  be examined by staff to  see how it might be included in the City's Capital plan for 2010.

Watch for the announcement of how Deputy Dan and the band are going to blow the $34,000 saving!!
Good idea however I don't think there will ever be any real reduction in GHG emissions. Any energy saved by this project will just get used by someone else for something they couldn't do before!
If the human eye can't detect the reduced lighting why not leave them lower all the time?
I dont know how many times I have driven by the ball park on north nechako at mindnight and all those lights are on. The gate is closed and no vehicles there. Why not start with firing the employee who can not remember to turn off the lights there. Those lights are a huge power draw and the tax payers pay that bill. Start with the things that wont cost us a dime then move forward on your pipe dreams.
GHG emissions, some one show me the science, anyone. Chasing carbon is only going to cost the economy big time. Folks sorry to tell ya the globe is in a natural cooling phase now, it was in a warming phase before

If Australia went to zero emissions that would only lower the temperature 1/10000 of a degree over one hundred years.

Enjoy paying your carbon tax. People scream about the cost of the olympics or the rcmp building but hardly a squeak about the costs of this C02 BS. Why is that?
Good one duffer! Why bother with the dimming hardware and sensors, can't they just use a lower power light if there are no noticeable differences? I must be missing something here.
They could eliminate far more Green House Gases by simply making the stop lights work more effectively. I could go on all day about the incompentancy of our governments managment of the stop lights and the kind of programming they are set at.
You guys got it right!!!!

We are dealing with the human eye here. We do not care about the eyes of dogs or bears.

If the human eye cannot detect the difference, get lower lumen bulbs!!!!

BUT, please read what the statement says: "According to the research, slowly reducing the energy supply to a street light by 40% OR MORE cannot be detected by the human eye and creates no real reduction in lighting levels."

Perhaps the statement should read OR LESS.
If we mortals (non expert, non politician, non celebrity of the day) are not 'bright' enough to notice the difference that 40% less power to a light bulb makes, why spend $170 grand? to save carbon? It would seem that our city is eager to jump on the same green coloured bandwagon as the geniuses who espouse 'cash for clunkers'
which is a government sponsored program to help car makers sell new cars. All it takes is a sharp salesman.
metalman.
Maybe they could take some of the ones they remove and put them up on the frontagae road between Walmart and Westgate. It won't save them any energy but maybe it will save a life or two. As a driver I find it damn near imposible to see the pedestrians on this road at night.
They can dim the one outside my living room window completely. Damn that thing's harsh.
***Now the City of Prince George is being asked to install 1425 of the special street lights*** Who is asking us to install these lights??? Hmmmm??? Could it be the manufacturer?. No doubt they will then use Prince George as a selling tool to sell their product to every other City.

The dimmest lights in the City are inside City Hall.

City planners, purchasing agents, managers, alderman etc;, should be required to fork over 5% of their salary for every City project that does not perform to the level it was originally designed to perform to.

Im still, after 10 years waiting to see the first blind person to cross an intersection using the vocal system that was installed. All I ever hear is this stupid recording, however I have never seen it used. Has anyone???? This to was a first, and we got some accolades for it, however if its not being used, what good is it?????
How can you lower Greenhouse gases by turning down your lights? You can't because our power comes from a turbine; not a coal powered plant. Get real! Stop feeding us BS. Also stop feeding us BS about global warming. Check your gas consumption this winter and tell me all about global warming. Remember the long winter last year and the late coming spring? Now we have an early frost that kills the leaves before they turned color. Turn up the thermostat and use the remote to warm your transpo.
Actually Supertech, I think we dial back our dams at night and buy cheap coal generated (from steam TURBINES) power during off peak times, so we can sell hydro for big bucks during peak periods. But that's a whole other ball o' green wax.
