Lighting alone is about 19-20% of US load on a historical basis.

The internet has clearly had an impact - given the timeframe of 1998 of decoupling from GDP, that almost has to be a big driver.

But the unexpectedly quick move to LED lighting also has had a big impact.

Just a decade ago, people were predicting much higher prices for LED bulbs. Now you can buy the bulb and the payback period is less than a year.



My firm’s factory switched to LED lighting in 20016 and, as projected, we’re already in the black. Provided MTBF rates are as expected, we’ll be in the black permanently. We’re saving up to 60% of our lighting costs (including capital expenses).


Approximately how much were you spending on traditional versus LED lighting? Also, what’s your electricity cost?

Here in the Bay Area my costs are approximately 30c kWh so energy saving are quickly and easily net positive.


I don’t think I can disclose that, but I’m in Italy so it’s probably not very comparable.
