ENERGY STAR® Efficiency

ENERGY STAR® certified homes are at least 10% more energy-efficient than homes built to code and achieve a 20% improvement on average while providing homeowners with better quality, performance, and comfort.

In addition, more than 98,000 homeowners retrofitted their homes through the Home Performance with ENERGY STAR® program in 2019, for a total of more than 880,000 to date.

ENERGY STAR® tools and resources help businesses identify cost-effective approaches to managing energy use in their buildings and plants—enabling the private sector to save energy, increase profits, and strengthen their competitiveness.

From commercial properties such as hospitals, schools, and offices, to industrial facilities such as cookie and cracker bakeries and integrated steel mills

ENERGY STAR® contributes to improved environmental quality and public health.

In 2018 alone, ENERGY STAR® helped Americans save nearly 430 billion kilowatt-hours of electricity and avoided $35 billion in energy costs with associated emission reductions of:

  • 330 million metric tons of greenhouse gases,
  • 220,000 short tons of sulfur dioxide,
  • 210,000 short tons of nitrogen oxides, and
  • 23,000 short tons of fine particulate matter (PM2.5).

Since 1992, ENERGY STAR helped families and businesses achieve 3.5 billion metric tons in greenhouse gas reductions.
