About This Data

Based on the U.S. Energy Information Administration (EIA) Residential Energy Consumption Survey (RECS) 2020 data.

Note: Percentages represent share of total electricity consumption in a typical single-family home. Regional climate and home size significantly affect these proportions.

Key Insights from This Data

HVAC Dominates Energy Use

Heating and cooling alone account for nearly half (47%) of household electricity, making HVAC efficiency the single most impactful area for reducing energy bills.

Water Heating Is the Second Largest Consumer

At 14%, water heating is a substantial but often overlooked energy cost. Switching to a heat pump water heater or lowering the thermostat setting can yield meaningful savings.

Lighting Has Declined Thanks to LEDs

Lighting at 12% has decreased significantly over the past decade as households switch from incandescent to LED bulbs, which use up to 75% less energy.

Electronics Are a Growing Share

Electronics and media devices at 9% reflect the proliferation of TVs, computers, gaming consoles, and smart home devices in modern households.

Best Practices for This Chart Type
  • Use a warm-to-cool color spectrum (red for heating, blue for appliances) to intuitively convey energy-related categories.
  • Include kilowatt-hour (kWh) values alongside percentages for readers who want to estimate costs.
  • Note the geographic region and home type since energy profiles vary dramatically by climate.
  • Add cost estimates per category by multiplying kWh by the local electricity rate.
  • Compare to national averages or Energy Star benchmarks to provide actionable context.
