Installing Energy-Efficient Indoor Lighting Systems

It’s no secret the cost of electrical energy continues to rise and will inevitably continue to do so in the future. At the same time, the demand for electricity continues to increase, taxing our existing electrical infrastructure to the margins of their design limits. We need more power, but in order to get it, we need new transmission and distribution infrastructure — but that’s just the beginning.The U.S. Energy Information Administration (EIA) estimates that about 461 billion kWh of electricity were used for lighting by the residential and commercial sectors in 2011. This was equal to about 17% of the total electricity consumed by both of these sectors and about 12% of total U.S. electricity consumption. Residential lighting consumption was about 186 billion kWh — or 13% of all residential electricity consumption. The commercial sector, which includes commercial and institutional buildings and public street/highway lighting, consumed about 275 billion kWh for lighting — or 21% of commercial sector electricity consumption in 2011.
