Apa sih Global Warming ? - July
REPLACE YOUR LIGHT BULBS
Incandescent bulbs : up to 90% electricity wasted as HEAT, only 10% is visible light.
Compact Florescent light bulbs (CFLs)
only use 25% - 40% as much energy than incandescent bulbs last 10 - 15 times longer and release 70% less heat
Light Emitting Diodes light bulbs (LED)
only use 10% - 25% as much energy than incandescent bulbs last 100 times longer and release minimal heat
REDUCE GLOBAL WARMING :
Turn off the lights when you leave the room, use only as much light as you need.
