An Arizona bill to prohibit local government mandates for energy-efficiency standards in new buildings is stirring debate.
Republican Sen. Chester Crandell of Heber said his bill is an attempt to hold down construction costs and to let builders choose what features to include in new construction.
Some astronomers say the bill could hamper efforts to protect dark skies if it is read as barring local governments from requiring low-intensity outside lighting.
And the bill is opposed by city and county who say it crimps local control.
The Arizona Daily Sun reported that Crandell's bill has cleared a Senate committee.
