Sustainability Defined

Sustainability Defined is the podcast that defines sustainability, one concept (and bad joke) at a time. Hosts Scott Breen and Jay Siegel explore a new topic each episode with the help of an expert in the field. Each concept falls into one of seven sectors -- Energy, Cities, Natural Environment, Transportation, Business, Policy, and Social -- and is visually represented in a Sustainability Tree found at www.sustainabilitydefined.com.

Many Definers may enjoy laying in a lush, green lawn staring up at a blue sky while listening to the latest Sustainability Defined episode.

Ep 57: Energy Storage with Marek Kubik (Fluence) 05.02.2021

Alas, it's time for us to stop storing this episode and release it to our Definers.

So, first on this episode, we read a statement on racial justice. We've done a lot of reading and thinking over the past several weeks and wanted to acknowledge the fact that we have failed in a number of ways wh...
