Energy Efficiency - tips for saving electricity...save environment

Energy efficiency is the low hanging fruit of greenhouse gas reduction. By taking a little care with how we use electricity, we not only lighten the load on the environment, but save cash too.

Electricity saving example: computers

I'm writing this by the light of a 1 watt LED lamp and on my laptop with power saving features switched on - using 50 watts per hour maximum. Back some years ago, I would have been basking under the light of a powerful incandescent globe and using a desktop computer with a 17" CRT screen - around 300 watts all told.

So what do those savings come to in terms of carbon emissions?

The following are some rough calculations based on coal fired power generation for just the computer aspect.

Laptop = 50w x 10 hours a day x 365 days = 182.5 kilowatts
Desktop = 300s x 10 hours a day x 365 = 1095 kilowatts

A huge difference as you can see and in terms of carbon emissions, the savings by using a laptop are around 1500 rupees annually for me - well over half a ton.
