Energy used for lighting.
1.Lighting is a major source of electricity consumption.
3.19% of global electricity generation is taken for lighting
• This 19% is > production of all hydro or nuclear stations.
• This 19% is = the production from natural gas.
---said Paul Waide, a senior policy analyst with the IEA
The emission equivalent
The carbon dioxide produced by generating this 19% electricity
•Is about 70% of global emissions from passenger vehicles,
•Is about 3 times the emissions from aviation, the IEA says
Ways to reduce the lighting load
1. Switching over to more efficient light sources like CFL, LED etc..
3. By eliminating wastages in the use of lighting.
An ever valid proposition …………….
Switch OFF the lights when not needed
Understand the illumination needs … reduce excess light
Manual vs. Automatic switching
Manual control is prone to errors and leads to energy wastages.
Manually switching public lights involves drudgery and also costs labor.
Manually dimming during mid night is impracticable.
Dynamically tracking the light level is manually impracticable.
Automation is a one time capital cost giving a lasting solution.
