“Western Cape-based brewery Cape Brewing Company (CBC) has, with the help of renewable- energy company E3 Energy Group of Companies, produced what it says is South Africa’s first commercially available green beer, using water heated by the sun”, Engineering News reported.
The Centre of Renewable and Sustainable Energy Studies had some input into this project which is hopefully just the start of demonstrating the value solar thermal energy has in local commercial and industrial processes. Learn more about this project by E3 Energy in this video.
