How to reduce domestic energy consumption? Tips!! Part-(i)

Lighting System  

• One of the best energy saving device is the light switch. Turn off lights when not required.  
• Automatic  devices like infrared  sensors,  motion  sensors, occupancy sensors,  automatic  timers,  dimmers  and  solar  cells  wherever  applicable, to switch on/off lighting circuits can  help  in  saving  energy  used  in  lighting.    
• As for as possible use task lighting, which focuses light where it's needed. A reading lamp, for example, lights only reading material rather than the whole room.  
• Dirty tube lights and bulbs reflect less light and can absorb 50 percent of the light, so clean your tube lights and lamps regularly.  
• Fluorescent  tube  lights  CFLs  convert  electricity  to  visible  light  up  to  5  times  more  efficiently than ordinary bulbs and thus save about 70% of electricity for the same lighting  levels.  
•  Ninety percent of the energy consumed by an ordinary bulb (incandescent lamp) is given off as heat rather than visible light. Replace  your  ordinary  bulbs (incandescent  lamps)  with  more  efficient  types.  LED lamps, Compact  fluorescent  lamps  (CFLs)  use  up  to  80  percent  less  electricity  than  incandescent lamps.  
• A  15-watt  compact  fluorescent  bulb  produces  the  same  amount  of  light  as  a  60-watt  incandescent bulb. 

Computers

• Turn off your home office equipment when not in use. A computer that runs 24 hours a day, for instance, uses more power than an energy-efficient refrigerator.   
• If your computer must be left on, turn off the monitor, this device alone uses more than half the system's energy.   
• Setting  computers,  monitors,  and  copiers  to  use  sleep-mode  when  not  in  use  helps  cut energy costs by approximately 40%.   
• Battery chargers, such as those for laptops, cell phones and digital cameras, draw power whenever they are plugged in and are very inefficient. Pull the plug and save energy.    
•  Remember Screen savers save computer screens, not energy.
•  Start-ups and shutdowns do not use any extra energy nor are they hard on your computer components. In fact, shutting computers down when you are finished using them actually reduces system wear and saves energy.
