Energy Saving, Beyond the Earth Hour

Hits:  Date:2012-11-18

Every year on a given day cites across the globe pledge to commit themselves to lasting environmental actions. Many are participating to switch off lights on the 26th of March at 8.30pm but for the long run, cities have switched to LED lights, initiated long term water protection and tree planting initiatives, reforesting land running into hectares, developing carbon credit policies, etc

Landmarks and global icons such as Gateway of India, Taj Hotels in Mumbai and Delhi, India Gate, Chhatrapati Shivaji Terminus in Mumbai, Bollywood celebrity ¨C Vidya Balan & Cricket legend ¨C Wasim Akram are joining millions of people from community, business, government, transcending barriers of race, religion, culture, society, generation and geography in a global celebrations of their commitment to protect one thing that unites us all.

Since the first earth hour, in 2007 till date 4600 cities have switched off lights but now we need to go beyond the hour. After you have switched the lights back on,¡®Rethink Dimming.¡¯

History of dimming was rewritten in 1960, when Founder of Lutron, Joel Spira invented the first ever energy-saving electronic dimmer. Before that, dimming was done with bulky rheostat dimmers which could only dim by transforming electricity into heat without saving any energy at all.

Energy Saving has become a global concern with consumers, corporations and governments alike demonstrating their desire to provide a sustainable environment for future generations. There are many different approaches to deal with this hot issue: recycling, less usage of plastic bags, turning the car off when stationary, setting the room temperature to 25.5 C. However an area that is often over looked in reduction of energy is lighting, even though it is the most common source of energy consumption in any building

Dimming helps households and organisations alike to make a significant contribution towards the protection of the environment by reducing energy consumption, lamp replacement and all associated costs. Other benefits being an increase in comfort level, the prevention of distractions, the ability to enhance moods, the extension of lamp life and just having the convenience of choice.

The key to dimming is TRAIC (TRIode for Alternating Current). At the heart of any dimming component, an electronic switching component allows current to flow in either direction. It allows light to be switched on and off very rapidly ¨C approximately 120 times a second. The longer the light is on vs off, the lower is the light output

Dimming Electricity Saved Bulbs Last Longer
10 % 10 % 2 times longer
25 % 20 % 4 times longer
50 % 40 % 20 times longer
75 % 60 % > 20 time longer

So, Switch off and Dim on

The beauty of dimming is that by dimming 10%, your naked eyes won¡¯t even notice the difference in light level as your pupils will automatically enlarge to allow more light in. So you can virtually save energy without noticing the change in light level. Beside, dimming can give you the desirable light level for different activities. Some activities like reading require brighter light level while other activities like dinning or listening to music need lower level and more ambiance.
