Do Dimmer Electrical Switches Save Electricity?


Electrical switches are found in every room of your home. Depending on the age of your dimmers, some of them could be saving on electricity. 

Dimmer switches are most frequently installed to improve a room’s ambience, offering both bright and dim lighting from the same fixture. These electrical switches can reduce energy consumption and reduce your power bill cost. BBC’s Science Focus explains, “Modern dimmer switches work by using circuitry that rapidly turns the electricity to the lights completely on or off, with the switching rate determining the brightness.” Therefore, modern dimmer switches can save energy, especially when combined with LED bulbs. 

The earliest dimmers could decrease a light bulb’s brightness by feeding less electricity into the bulb, but still consumed the same amount, and needed to convert the remaining unused energy into heat. Fortunately, there is a modern solution to this inefficient method.
