Human creativity is one of the most extraordinary "natural resources" that exist on our planet Earth.

Creativity is fueled, in most cases, from conditions of need, crisis situations.

"It is in crises that arise inventiveness, discoveries, and big strategies"
(cited by A. Einstein)

This section of the site, which we have called "Efficiency Alternative", is a tribute to human creativity. Here we collect the most interesting, amusing, and sometimes extravagant applications of creativity combined with Energy Efficiency and exploitation of Renewable Sources on the Planet.
