Understanding Energy Poverty & Energy Burden
- Energy poverty occurs when households can’t afford essential energy needs.
- Energy burden measures the percentage of income spent on energy bills—anything above 6% is considered high, and over 10% is severe.

The following maps show the percentage of low-income households that are experiencing high (yellow) and severe (blue) energy burden in the Phoenix Metropolitan Area.
