Big Green: How many gallons of water do you need to power a lightbulb?

[Christopher Schaffner]

We sometimes forget the connection between water and energy use. In fact,
energy production uses a lot of water, and water use consumes significant
amounts of energy, due to pumping and treatment requirements.

I found an article addressing some of this, which I thought might be of
interest.

How many gallons of water do you need to power a lightbulb?
Here's a measurement you probably haven't thought of before: it takes
between 3,000 gallons and 6,000 gallons of water to power a 60-watt
incandescent bulb for 12 hours a day over the course of a year. That
statistic was published on Thursday by researchers at Virginia Polytechnic
Institute and State University, who have studied how demand for a dwindling
natural resource--fresh water
<http://www.news.com/8301-11128_3-9822083-54.html> --plays into energy. 
 ..etc.

Follow the link for the full article.

Cheers,
