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.
Energy-efficient landscaping, a type of landscaping designed for the purpose of conserving energy; Efficient energy use, minimizing the amount of energy used for a given, constant energy service; Energy conservation, reducing energy consumption by using less of an energy service
Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at ...
Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical , electric power , mechanical work , light (radiation), or heat .
The use of low-emission energy sources to produce electricity; Electrification – that is increased use of electricity instead of directly burning fossil fuels; Accelerated adoption of energy efficiency measures [136] Some energy-intensive technologies and processes are difficult to electrify, including aviation, shipping, and steelmaking.
Energy sector regulators can have wide discretion in the implementation and/or monitoring energy efficiency (EE) initiatives. The most likely roles involve giving technical advice to the agency developing EE initiatives, since changes in demand patterns will have implications for the operations and investment plans of utilities.
The VDI-Guideline 4602 released a definition which includes the economic dimension: "Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives".

Energy efficiency of appliances and buildings (through use of building materials and methods, such as insulation), fuel economy of vehicles, vehicular distances travelled (frequency of travel or larger geographical distances), better methods and patterns of transportation, capacities and utility of mass transit, energy rationing or conservation ...
