How to lower the cost
- Heat-producing devices (dryers, irons, beds) dominate this category — minutes of use, not watts, drive cost.
- Medical devices that run all night or all day may qualify for utility medical-rate discounts — ask your provider.
- Chargers left plugged in draw almost nothing on modern hardware; focus on bigger loads.
