Right.
What are the results of a CBA? How much does a city have to pay to install each LED.
The energy savings and the replacement lamp savings should be significant. Unless this is balanced against the cost of installing the LED in the first place, and scrapping the old lamps, the savings data is useless.
I paid $5,000 for a new HE central A/C, new ducts, and new attic insulation in my home. Then I paid $18,000 for new radiant barrier, siding, doors, and windows.
My peak electric usage in the summer dropped by about 45%, saving me about $90 a month for four months a year, and much less than that during sub 90 degree months. All in all I reduced my electical usage by about 6,000 KwH a year, or about $600 or so. I spent $23,000 and save $600 a year in energy costs. The ROI? Never.
However, the benefits of a much more comforable home are incalculable. And, since the costs have been paid, I do reap a benefit of $600 a year lower cost of living. I'm just out the twenty-four G's.
I sure don't want my city to operate that way, unless they follow the same plan... I raised the $24,000 by spending less in other places, not by confiscating money from other people.
