 Why Is Energy Efficiency Important for Delaware?

Making your home energy efficient can help Delaware’s economy and environment, as well as help you save!

Lower your spending on energy. Simple efforts can be made to help reduce monthly energy bills by up to 30 percent, including:

  • Replacing regular incandescent lightbulbs with compact fluorescent lightbulbs (CFLs)
  • Adjusting your thermostat
  • Upgrading to high efficiency appliances
  • Weatherizing your home by insulating electrical outlets, windows, doors, attics and other areas that may let in drafts
  • Reducing your energy use during peak use times (for more information about peak times, please visit your utility company's website)

Most of these steps you can take with little out-of-pocket costs…and the best part is you can see results in a short time!

Improve air quality by reducing air pollution and greenhouse gas emissions. By doing your part in energy conservation, you can help improve public health by reducing harmful air and water pollution, making Delaware a safe home for you and your loved ones.

Helps Delaware keep utility prices manageable for everyone. The more energy is used by residents and businesses, the higher prices will go in the future, making it harder to provide residents with the energy that they need for everyday routines.

Create new jobs for Delawareans. Cutting energy costs can increase spending in other areas, providing well-paying jobs for those in need of employment.

Who uses our energy?

The largest consumer of electricity in Delaware is the industrial sector as it is home to several energy-intensive industries, including a major petroleum refinery, chemical plants and large manufacturers. The transportation sector is the second largest and is almost completely dependent on petroleum fuels, mainly gasoline and diesel. The commercial and residential sectors account for the remainder of Delaware's energy consumption from space heating, air conditioning and water heating to a variety of electric appliances and equipment

Where do we get our energy?

Delawareans currently consume about 280 trillion BTUs of energy in different forms every year - equal to about 7.4 gallons of oil per person per day! 84% of this energy is delivered directly to consumers in the form of fossil fuels, including coal, petroleum products and natural gas. These fossil fuels provide energy to homes, businesses, industries and transportation, and help to generate a portion of Delaware's electricity. Another 15%, nearly all of the remainder, is delivered in the form of electricity to Delaware by out-of-state fossil and nuclear-fueled power plants*.

   *Note: Imported electricity does not include losses incurred in generating and delivering electricity from out-of-state power plants to Delaware.
