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.

Increased energy efficiency and weatherization spending has a high return on investment. [26] On August 4, 1977, President Jimmy Carter signed into law The Department of Energy Organization Act of 1977 (Pub. L. 95–91, 91 Stat. 565, enacted August 4, 1977), which created the United States Department of Energy (DOE). [27]
Extended and modified renewable energy tax incentives and defined electricity as a clean fuel. 2009 American Recovery and Reinvestment Act of 2009: Provided funding for an electric smart grid. Created and modified renewable energy tax cuts. Weatherized modest-income homes. Incentivized federal building energy efficiency.
These subsidies are part of the energy policy of the United States. According to Congressional Budget Office testimony in 2016, an estimated $10.9 billion in tax preferences was directed toward renewable energy, $4.6 billion went to fossil fuels, and $2.7 billion went to energy efficiency or electricity transmission.

United States building energy codes are a subset of building codes that set minimum requirements for energy-efficient design and construction for new and renovated buildings. [2] The intent of these energy codes is to moderate and reduce energy use and emissions throughout the lifetime of a building. [ 2 ]
The Energy Policy and Conservation Act of 1975 (EPCA) (Pub. L. 94–163, 89 Stat. 871, enacted December 22, 1975) is a United States Act of Congress that responded to the 1973 oil crisis by creating a comprehensive approach to federal energy policy.
The United States had a nameplate generation capacity of 1,213 GW in 2021. [7] The following table summarizes the electrical energy generated by fuel source for the United States grid in 2021. Figures account for generation losses, but not transmission losses. Fission had the highest capacity factor, while petroleum had the lowest.
Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.
