The Energy Star certification is a standard of energy efficiency for consumer electronics and appliances that is higher than what is required by federal standards. The program was a joint venture by the Environmental Protection Agency and Department of Energy and has since become an internationally-recognized standard.

While coal was the predominant source of energy during the Industrial Revolution, advancements in petroleum extraction and refining resulted in petroleum and natural gas becoming the dominant industrial fuel source in the 1950s. This pattern has existed to this day.
