The Johannesburg Zoo is taking their commitment to the environment to the next level and actively greening their operations – demonstrating how smart energy solutions like solar powered golf carts and bio-digestors (which turn food and animal waste into energy), can provide us with a heap of free, clean energy.

This video is the 5th episode of Transition SA, a six part documentary series that follows Project 90 x 2030′s team of activists and eco engineers as they bring green energy solutions to communities across South Africa and empower them to build a better future.
