“Earth Hour was both disappointing and pointless in Sydney. They didn’t even turn the lights off on the Opera House or Bridge really… just a few lights were shut down. I can’t imagine they really saved that much power.”

You were saying that this doesn’t save that much power? I did the math, it really does save a great amount of coal and resources. If the United States did this every once in a while the world would be better off. Here’s my findings:

If New York City turned off its power for one hour approximately 10.794 Tons of coal would be saved in that hour alone. Thats 21,588.33 pounds.

For those europeans and others who don’t use pounds, here is what that is converted in some other ways:
1542.0235 Stones
9792.3017 Kilograms

In other words, this power saved, could be used to power almost 900 electric heaters for 10 hours.

For some this electricity may not seem that important, but for those people huddled around the electric heaters, the power is appreciated.
(my data uses information from numerous sources, and i did my own calculations, i rounded to the closest decimal).

In the end, this data was all from if New York were to turn off the lights for a single hour. Imagine how much more could be saved if multiple countries and cities joined together to do this. I applaud the cities and people that are coming together to make this happen. Thank You, and I hope someday I may be proud to say my city has taken part in an Earth Hour as well.
