The Home Energy Saver website includes a section called LEARN which offers tips about energy savings, an explanation of the house-as-system energy efficiency approach, and other information to help people understand how energy is used in a home. When launched in 1994, Home Energy Saver was the first and only online home energy calculator.
In fact, International Energy Agency has calculated that the application of energy efficiency measures in the years 1974-2010 has succeeded in avoiding more energy consumption in its member states than is the consumption of any particular fuel, including fossil fuels (i.e. oil, coal and natural gas).
In 2050, energy savings in Europe can reach 67% of the 2019 baseline scenario, amounting to a demand of 361 Mtoe in an "energy efficiency first" societal trend scenario. A condition is that there be no rebound effect, for otherwise the savings are 32% only or energy use may even increase by 42% if techno-economic potentials are not realized. [43]
Energy Star is a similar labeling program, but requires more stringent efficiency standards for an appliance to become qualified, and is not a required program, but rather a voluntary one. See also [ edit ]

Energy in this sector has the same basic end uses as the residential sector, in slightly different proportions. Space conditioning is again the single biggest consumption area, but it represents only about 30% of the energy use of commercial buildings. Lighting, at 25%, plays a much larger role than it does in the residential sector. [12]
