It's not often that we as artists have the opportunity to give back, so when there's a chance to do that we should jump on it. For those photographers with a Flickr account, General Electric (GE) has an ongoing 'ecomagination photo project' that is dedicated to bringing water, solar power and wind energy to those countries in most need.
There are three different categories:
All you have to do is upload to Flickr through GE's Ecomagination Photo Project website photos for one or all categories. Give the photos a title, a short description, and then tag with either "wind", "water" or "light". Then simply share the links with your friends on Twitter or Facebook.
I'm not quite sure of the actual mechanics, but GE in conjunction with three different charities will then donate the following:
4.5kW hours of wind energy for every wind photo
175 hours of solar power for every light photo
480 gallons of drinking water for every water photo
In other words, your photos will build a wind turbine to power health clinics in rural parts of Peru, build clean water wells, and provide families in East Timor with solar-powered lanterns.
For more information check out their website and give upload a few yourself.
