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.
Luminous efficiency, a measure of how well a light source produces visible light; Fuel efficiency, the efficiency of converting potential energy in a fuel into kinetic energy; Energy efficiency in transportation, the fuel economy of various modes of transportation; Energy-efficient landscaping, a type of landscaping designed for the purpose of ...
Perceived risk of energy-efficiency investments. Consumers and businesses can be very risk-averse in terms of investing in energy efficiency technologies. The uncertainties of fuel prices and high discount rate for operating costs have both made energy-efficiency investments even more "risky” for many decision makers. Information gaps.
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
Energy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. [1] Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. [2]
Technological improvements in energy efficiency may result in a small take-back. However, even in the long term, energy efficiency improvements usually result in large overall energy savings. Even though many studies have been undertaken in this area, neither position has yet claimed a consensus view in the academic literature.
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.
An inverse way of looking at the issue would be an 'economic energy efficiency,' or economic rate of return on its consumption of energy: how many economic units of GDP are produced by the consumption of units of energy. Referring to the above examples, 1 million Btus consumed with an energy intensity of 8,553 produced $116.92 of GDP for the US ...
