  •  Lighting is the #2 electricity consumer nationally (0+ / 0-)

    After air conditioning. So this LED revolution has massive, massive green implications.

    As a former Philips copper and steel lighting engineer who occasionally "borrowed" from the electronics group's test equipment and supplies, let me please beg you to call them



    •  One wonders, however (1+ / 0-)

      How much of that "lighting" is ordinary household lighting, and how much is industrial lighting that is on 24/7, commercial signage, and the masses of high-intensity "street" lights illuminating the acres of car-dealership parking lots day in, day out, so that no one can drive by without seeing the AWESOME DEALS on display.

      In other words, how much of that light is actually being used by real people to live their lives, and how much is the desperate attempt of somebody with Something To Sell to compete for the limited interest of people with no need to buy?

      •  Fortunately, some of that commercial lighting (0+ / 0-)

        is being changed to LEDs.  I've seen a lot of new LED lights at a local recently-renovated gas station.  There is an excellent business case for switching to more durable bright lights in hard to reach places that use much less energy.

        •  Good point. (0+ / 0-)

          Personally, I think we should just outlaw wasting electricity for frivolous marketing purposes, with those animated big screens that try to flash all their sales events at you WHILE YOU'RE NAVIGATING TRAFFIC with people zipping in and out around you going first.  Hollande's move to turn out the 24-hour lights in Paris is a first step.  150 years ago, lighting up a city so you could see it from twenty miles in the air was a miracle.  Now it's a nuisance that makes it hard to see the stars.

          In the meantime, if I were running a business like those huge car-sales lots, you'd better believe I'd be looking into reducing costs by investing in the best available technology.  One reason I prefer lower tech is that the margins are relatively small compared to the capital on the small scale.  With heavy use and long lifetimes, the numbers change dramatically.
