Reducing energy use is important because most energy production
contributes to problems such as carbon dioxide emissions (tied to
global warming), mercury
releases, acid rain,
volatile organic compoundsCompounds that evaporate easily (volatile) at room temperature and often have recognizable odor; primarily used in solvents; many are chlorinated hydrocarbons and some are carcinogenic (e.g. benzene, chloroform, and methyl ethyl ketone)., and nuclear waste.
The U.S. Environmental Protection Agency and U.S. Department of
Energy developed the Energy Star label to help purchasers identify
energy-efficient products. These products reduce utility bills and help the environment.
