  • Total energy savings: 77 TWh per year electricity savings and 352 TBtu per year on-site fuel savings for households with 200% of the Federal Poverty Level.
  • Cost savings: $13 billion in annual savings for low-income households.
  • State-level energy bill savings for low-income households: range from 17.6% to 32.3%.
  • Cost-effective electricity savings: up to 30% of low-income households electricity use.  
  • Bill savings in all households in Persistent Poverty Counties: $2.4 billion.
  • Additional estimations of cost effective energy savings are identified by income measurements. Example: $16 billion in annual savings potential for households under 80% of Area Median Income (not shown).
