Brighter, safer streets ahead Comments on Stories, posted by Editor, Pleasanton Weekly Online, on Jan 29, 2013 at 3:27 pm
Within the next month or two, Pleasanton's energy and sustainability manager Laura Ryan will have obtained sufficient low-interest loans and other financial funding to win the City Council's approval for one of her most ambitious projects ever: the installation of 7,300 street lights and numerous park lights that will not only make our roadways and neighborhoods brighter at night but also save our city millions of dollars in future electric bills. The project is one of many Ryan and her boss Daniel Smith, director of operations services, have advanced in recent months at the council's direction in a long-term commitment to financial sustainability and a reduction in community-wide greenhouse gas. Their success has made Pleasanton a recognized leader among municipal and state climate action plans to reduce emissions and clean up California's air.

While i am all for more efficient and reducing energy consumption, do we really need brighter? Just more light pollution and less stars. Night is supposed to be dark. Less carbon foot print, but a brighter foot print on the night sky....

The key question is not so much how bright the lights are, but where does the light go. Light that just escapes upward to the sky is a nuisance as well as a waste of energy. for those of us who like to do amateur astronomy, including school star parties for students the scattered light from the sky makes it hard to find interesting things for the students to look at. There are plenty of designs that direct the light downward instead of letting a lot of it illuminate the sky.

From my memories of looking out the windows of airplanes flying at night over cities and towns, I don't recall street lighting as being a big source of light as viewed from above. The streetlights aren't all that bright and are directed downwards so that the light has to bounce off the dark pavement in order to get to the sky. The bright lights that I noticed were from car headlights, office lights, and storefront lighting and brightly lit signs.
As for LED streetlights, they're now being used at Lawrence Livermore Laboratory. They haven't yet completely switched over so one can see some sodium arc streetlights and LED streetlights in close proximity. The LED's do appear to be a little bit brighter and their light is much whiter than the dull yellow of the sodium arc lights.

Several years ago ALL of the street lights in Valley Trails were replaced with "Quaint", and energy efficient lights. Now they are going to be replaced, at what cost. Someone needs to have their priorities examined.
