When you dim a light, you lower the amount of energy flowing to that light bulb. Thus, using dimmable lights – and using them on lower settings when possible – can save a lot of energy, which saves you money, and reduces the amount of carbon dioxide being released by power plants. Dimming can also be good for your living style. Dimmed lights are softer on your eyes, reduce glare, and are great for creating calm and peaceful spaces.
The best kind of lightbulbs to buy are compact fluorescent lightbulbs (CFLs), which not only use about a quarter of the energy that traditional incandescent bulbs use, but also last much longer. Not all CFLs work with dimmers though, so make sure that the bulb is labelled as dimmable by the manufacturer.
Did you know that almost a pound (lb) of CO2 is released for every kilowatt-hour (kWh) of energy that you
use?
According to the U.S. Department of Energy that is about how much CO2 is released into the
atmosphere when one 100W light bulb is on for ten hours. Over time, all that CO2 adds up – and contributes to
global warming.
