==Lighting and Energy Use==
[[File:360px-Hitachi,_LED_light_bulb,_LDA15D-G,_E26_cap,.jpg|400px|framed|Figure 1. LED light bulbs are some of the most energy efficient light bulbs available and can reduce energy costs.<ref>Wikimedia Commons. (May 27, 2015). ''Hitachi LED light bulb'' [Online].

Residential lighting uses a significant amount of [[energy]]. In Canada in 2010, 4% of [[residential energy use]] was connected to lighting.<ref name=NRCAN1>Natural Resources Canada. (May 27, 2015). ''Lighting'' [Online]. Available: https://www.nrcan.gc.ca/energy/products/categories/lighting/13730</ref> Although the use of lights cannot be completely cut out, as it is necessary for comfort and functionality, it can be reduced. Lighting costs can be reduced by:<ref name=NRCAN1/>

* Using natural lighting when possible
* Installing more [[energy efficiency|efficient]] bulbs ([[halogen light|halogen]], [[CFL light bulb|compact fluorescent]], and [[LED light bulb|LED bulbs]] all have different efficiencies)<ref>National Resources Canada. (May 27, 2015). ''Light Bulbs'' [Online]. Available: http://www.nrcan.gc.ca/energy/products/whats-new/13583</ref>
* Turning lights off when not in use
* Using controls such as timers and motion sensors to ensure lights are not on when they are not needed
* Designing and using lighting with energy efficiency considerations

The appropriate measure for lighting is [[lumen]]s rather than [[watt]]s. Whereas watts indicate the amount of [[power]] used by the bulb, lumens represent the amount of light provided by the bulb.<ref name=NRCAN1/> Comparing wattage can be misleading, as bulbs that use less energy may still provide the same amount of light (in lumens). Using lumens to compare bulbs allows for more direct comparisons of light quantity.

For more information about the efficiency of different light bulbs, see National Resources Canada's page [https://www.nrcan.gc.ca/energy/products/categories/lighting/bulbs/13918 here] or [[light bulb|this page]].

==Lighting in Underdeveloped Countries==
Limited [[access to electricity]] in [[developing countries]] often leads to lower quality lighting. It is estimated that around 1.2 billion people worldwide do not have access to [[electricity]] in their homes,<ref name="RE2">World Bank. (May 27, 2015). ''Energy Overview'' [Online]. Available: http://www.worldbank.org/en/topic/energy/overview#1</ref> many of these, approximately 95%, being people located in Africa and Asia.<ref name="RE3"> International Energy Agency. (May 27, 2015). ''Energy Poverty'' [Online]. Available: http://www.iea.org/topics/energypoverty/</ref> As well, most of the people who do not have access to electricity are part of the [[rural population]], with about 84% of people without access to electricity living in rural areas.<ref name="RE3"/> In addition to this, those who do not have access to electricity use other fuels for cooking and lighting. These fuels are less efficient, more [[pollution|polluting]], and provide a lower quality of light. The [[access to non-solid fuel]]s is important to improving lighting quality as solid fuels are some of the most polluting. In Figures 2 and 3 a comparison of the light provided from a kerosene lantern and an LED lamp are shown. It is clear that the [[kerosene]] lantern provides much poorer light which makes working, studying, and other tasks more difficult. As well, the [[incomplete combustion]] of [[fuel]]s such as charcoal and kerosene results in harmful and polluting smoke that poses a significant heath risk.<ref>The World Bank. (May 27, 2015). ''Tracking Access to Nonsolid Fuel for Cooking'' [Online]. Available: http://www-wds.worldbank.org/external/default/WDSContentServer/WDSP/IB/2014/05/15/000333037_20140515114123/Rendered/PDF/880590BRI0know00Box385214B00PUBLIC0.pdf</ref> Using these fuels increases chances of death from pneumonia, stroke, heart disease, chronic obstructive pulmonary disease (COPD), lung cancer, and other ailments.<ref>The World Health Organization.
