A refrigerator sold today uses about 70% less electricity as one sold in 1970. [11] It has been estimated that these standards have saved American taxpayers over $300 Billion in energy savings. [11] Overall these standards have reduced total American energy use by 3.6%, or about 3.6 quadrillion BTU"s every year.
(72,000 BTU/h) × (1000 h/year) × ($0.12/kW·h) ÷ (10 BTU/W·h) ÷ (1000 W/kW) = $860/year. Example 2. A residence near Chicago has an air conditioner with a cooling capacity of 4 tons and an SEER rating of 10. The unit is operated 120 days each year for 8 hours per day (960 hours per year), and the electric energy cost is $0.10 per kilowatt ...
But even ordinary units are reasonably efficient; some smaller units use less than 0.2 kWh per day (equivalent to 8 W continuously). Larger units, especially those with large freezers and icemakers, may use as much as 4 kW·h per day (equivalent to 170 W continuously).
How long can my food last in the fridge after a power outage? Experts say it depends on the product, and whether it's in a refrigerator or freezer. Kaitlin Reilly. September 27, 2024 at 1:08 PM.
Example EU energy label for a refrigerator. EU Directive 92/75/EC (1992) [1] established an energy consumption labelling scheme. The directive was implemented by several other directives [2] thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent.
In February 2023 the United States Department of Energy proposed a set of new energy efficiency standards that, if implemented, will save to users of different electric machines in the United States around 3,500,000,000$ per year and will reduce by the year 2050 carbon emissions by the same amount as emitted by 29,000,000 houses.

From its founding until the late 19th century, population and energy use in the United States both increased by about 3% per year, [10] [11] resulting in a relatively constant per capita energy use of 100 million BTU. Wood made up the majority of this until near the end of the 1800s, meaning the average American burned eight tons of wood each ...
The US state of Louisiana had the highest annual electricity purchases per residential customer at 14,774 kWh and the US state of Hawaii had the lowest at 6,178 kWh per residential customer. [1] As of 2008, in an average household in a temperate climate, the yearly use of household energy is comprised as follows:
