Dr. Ian Rowbottom of Lutron Electronics authored a whitepaper on the Lutron website titled, “Building Dimmers Vs. Building Power Plants.”
Using simple math, he makes a case that while it costs $1.40-$7.75 to build a watt of electric generating capacity, it costs only about $0.35 to remove a watt with a dimmer.
He writes, “At 35¢/Watt, it is far cheaper to conserve electricity with dimmers than it is to install new power generating equipment. Another advantage: Dimmers are available immediately and can be installed on the same day of purchase, whereas it can take decades to plan and build a power generating plant.”
