One way if you think about it - its nice. Reduce the power consumption and make a point. But the more I think about it I believe that its all a farce. I mean why this one day? Why one hour? Back when I was in India we knew the importance of saving power and saving resources. But then visiting other parts of the world just opens up your mind. You see how people just don't understand the point. They are not to be blamed, its the system thats messed up. They have not been told (or are unaware) that there's soon gonna be a shortage. 

I think last year Sydney made a point and showed it to the whole world that its important to conserve. How can we be selfish to use up the resources as if there's no tomorrow and not leave much for the coming generations? This year its Copenhagen, Chicago, Melbourne, Dubai, and Tel Aviv. Even google has jumped into the race and have their "Google Blackie" thing put up.

If we really have to make a difference, switching power for 1 hour on a particular day wont help at all. If you just visit any city-downtown in the US (for example) in the evening/night you would know what I'm talking about.  All those towers and all those fancy looking buildings are lit up the whole day, the whole night for weeks, months and years. Looks good at night and feels nice to get a snap or two in front of the buildings but when it comes to conserving power and resources - it doesn't help at all.

Thats just one thing. Switching off your comp, switching off lights and heat when you leave the apartment/house, maintain your vehicle etc.. etc... are few other that one can start doing. Afterall "Rome was not built in a day". I read somewhere that couple of years back several firms in Japan urged their employees to stop wearing Suits and Ties to work during summer and shift over to casuals. Less Air Conditioning costs :). Reduce the heating during winter and keep the thermostat at no more than 68F, make up by using warmer comforters, turn off car engines while idling at traffic lights; At work, use Canon's Pixus MP500 printer, which uses 60 percent less electricity than the company's other models, saving 10% power each time its switched on. 

What can I say - Just start with the Earth Hour today and make it a point to continue the good work :) 

Cheers !!
