Conserving Energy Reduces Waste

Currently in the U.S., electricity demand continues to increase even as energy efficiency gains are made.  Since 1970, the use of coal to generate electricity in the U.S. has nearly tripled in response to growing electricity demand.  Almost half of the electricity is presently generated by coal-fueled electric power plants.  The more electricity consumed the more coal that is being used for energy production. Consider that the U.S. Energy Information Administration projects that electricity demand will grow by 41% by 2030.  With the burning of coal to produce electricity, ash is produced.  In the process of converting coal into energy, the coal-fueled electric power industry generated approximately 72.4 million tons of coal fly ash (ash that rises to the chimney or stack), 18.4 million tons of bottom ash (ash that does not rise), and 2.0 million tons of boiler slag (molten ash) in 2008. Though some of the coal fly ash, bottom ash, and boiler slag can be used in cement, asphalt and construction projects, 70 – 80 percent of the ash ends up in a landfill.

Small changes in daily routines, such as turning off lights, unplugging appliances not in use, washing clothes in cold water, and maintaining moderate household temperatures reduces the amount of coal needed to produce electricity. So while you’re conserving energy, you’re also reducing waste!
