- zdragnar 1y agoNot all appliances I looked at were energy star certified. The energy guide (yellow label with cost estimates) is mandatory for most appliances. The energy efficiency is quantified as an estimated annual cost of operation. Energy star certification is a voluntary and binary thing. There's no readily visible difference between appliances with or without the energy star certification, short of going back to the energy guide label to compare.

There are knock on effects like economies of scale making energy efficient parts cheaper to source, marketing the latest technology driving consumer expectations, and manufacturers flat out copying each others’ designs.
