California at Night a Massive
Waste of Energy and Light

Surly this must represent more than $150,000,000 each year
 in unnecessary energy cost.  


 33,336,000 kWh/year six valley cities (metropolitan areas).

See Light Pollution and Green House Gas in Central California link below.

Cal-ISO implemented rotating outages for a
shortage of 2,000 MW during the power crises of 2000.

How much energy does it take to destroy the night sky?

How much energy does it take to mask the Milky Way?

Is the Milky Way a energy waste measurement tool?

The image at left is from a 1997 product from
USAF Defense Meteorological Satellite Program (DMSP) 1997.
Red represents very bright or intense light levels blue and purple less.
