Humans have been capturing and using geothermal heat from the earth for a very long time. Geothermal energy was being used in China back in the 3rd Century BC and the Ancient Romans, of course, used it to heat their baths and their buildings. Now, in the 21st Century, geothermal power comprises a significant portion of the energy grid in countries ranging from the Philippines to Nicaragua. This week on Sea Change Radio, host Alex Wise talks with Karl Gawell, Executive Director of the Geothermal Energy Association, an organization that advocates for the expansion of geothermal for electricity production. He explains how geothermal works, tells us who the major players are in the industry, and talks about what needs to happen to move the United States toward fully embracing this ancient but largely untapped resource.

This week on Sea Change Radio, host Alex Wise speaks with Dara O’Rourke, co-founder and chief sustainability officer of Good Guide.
So many of us try to be responsible, eco-conscious consumers: we walk or bike to our local food co-op or natural foods store, our re-usable canvas shopping bags in tow. But try buying organic or green products that don’t come in petroleum-based plastic packaging and you’ll soon be presented with another slew of challenges. Those of us who’ve been frustrated by this reality will be happy to learn that there are some people and companies working to reduce the use of plastic packaging in the food industry. This week on Sea Change Radio, host Alex Wise speaks with the founder of a zero-waste grocery store opening soon in Austin, TX, a nut butter entrepreneur who hosted an industry-wide summit to come up with compostable squeeze packs and a snack chip executive whose company has introduced a greener bag for its products.
