They predict that the introduction of solid-state lighting could increase the consumption of light by a factor of ten within two decades.To work out what solid-state lighting would do to the use of light by 2030, Dr Tsao and his colleagues made some assumptions about global economic output, the price of energy, the efficiency of the new technology and its cost.
The total energy consumption of lighting equipment is shown in the energy consumption bar.
This paper presents new trends and progressive strategies to reduce energy consumption of lighting systems.
The challenge in the U.S. is the fuel consumption of light trucks pickups and sport utility vehicles.
The field test results showed that application of electric heating light oil blending compound technology in heavy oil producing can significantly decrease the consumption of light oil.
Khattak says the unnecessary consumption of light switches or mobile phone chargers amounts for up to 16% of the UK's annual energy usage, or "enough to power almost 2.5 million homes".
Occupant presence and behaviour in buildings has been shown to have large impact on heating, cooling and ventilation demand, energy consumption of lighting and appliances, and building controls.
It is possible, and desirable, to add new directives to national legislation that contribute to the improvement of Portuguese buildings, characterized by its good performance in terms of daylight availability, and at the same time, increasing the energy efficiency and reducing the energy consumption of lighting systems installed in those buildings.
In addition, LED lighting can reduce the energy consumption of the lighting system by 30% and the LED lighting now is a common standard for automatic trains [4].
The test cases are based on three fundamental aspects of lighting design of buildings: (1) evaluating the illuminance level, (2) calculating the energy consumption of the lighting system, and (3) visualizing lighting appearances.
