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.
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]
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.
Energy efficiency may refer to: Energy efficiency (physics), the ratio between the useful output and input of an energy conversion process Electrical efficiency, useful power output per electrical power consumed; Mechanical efficiency, a ratio of the measured performance to the performance of an ideal machine
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 ...
Fuel efficiency is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. The fuel economy is the energy efficiency of a particular vehicle, is given as a ratio of distance travelled per unit of fuel consumed.
“A simple DIY home automation system focused on monitoring energy use can cost between $100 and $3000, depending on the smart devices you choose," says Kat Garside, a sustainability and energy ...
Market transformation describes both a policy objective and a program strategy [1] to promote the value and self-sustaining presence of energy-efficient technologies in the marketplace. It is a strategic process of market intervention which aims to alter market behavior by removing identified barriers and leveraging opportunities to further the ...
