National Geographic Green Houses

National Geographic Channel has created NG Green Houses - energy-efficient, low waste exhibition homes - in Lisbon, Portugal, and Bogota, Colombia and has invited the public to come and view the homes firsthand. National Geographic has provided school groups and the general public with online games and contests as well do-it-yourself information through their various media platforms. Lisbon's program includes the Green Supervisor, an online tool that teaches families how to correct potentially unsustainable behaviors, and the Bogota home uses a live digital display that shows energy savings compared to common energy use.
