Kathy Hannun, president and cofounder of Dandelion Energy, introduces an untapped heating and cooling capacity source for homes -- geothermal energy. Typically associated with high temperatures and geologically active areas such as hot springs or locations at the intersections of tectonic plates, geothermal heat pumps tap into the consistent year-round temperature of Earth’s outer crust to maintain a comfortable home environment. Dandelion emerged from Google X Lab and is transforming the heatin...

Clothing and textile recycling has historically been scarcely available to consumers. It has yet to be successful, with clothing piling up in warehouses or being sent overseas instead of becoming a new generation of apparel. Stacy Flynn, CEO and co-founder of Evrnu, a textile innovations B Corporation, works to reduce the fashion industry's environmental impact with a circular, recycled cotton fiber called Nucycl. In this crucial conversation, Stacy discusses how we can encourage companies to st...

Chance Cutrano is director of programs at the Resource Renewal Institute in Fairfax, California. He and his team are experimenting with blending two activities, rice and fish farming, to reduce the emissions from rice fields while creating additional income for farmers. It's a practice recovered from antiquity that led to the launch of the Fish in the Fields program, which lowers carbon equivalent emissions created by rice farming by as much as 66% while improving biodiversity. Fish in the Field...

Despite its other environmental impacts, including toxic waste that requires centuries or millennia of storage in facilities designed to protect future generations from the genetic and acute effects of radiation, nuclear power is considered by some influential environmentalists an essential component of the post-fossil fuel economy. For example, James Hansen, the NASA scientist who raised the alarm about global warming in Congressional testimony in 1987, advocates expanded nuclear energy generat...

How do you kickstart an industry? The $100 million XPrize for Carbon Removal recently announced its 15 winners in the first competition stage to achieve gigaton-scale carbon removal. With more than 1300 entrants in the XPrize process, the carbon removal prize may be the largest experiment in innovation in human history. The goal is to lower the cost of carbon removal to well below $100 per ton and ultimately to store atmospheric CO2 for centuries to halt and eventually reverse climate change. Th...

Nutritional supplements, which the Centers for Disease Control report that 57.6% of adults consume, have significant environmental impacts. One family of supplements, Omega-3 oils, the healthy fats about 20 million Americans take each month to support brain and circulatory health, is responsible for the decline of krill in the Southern Ocean around Antarctica and overfishing of pelagic fish, such as anchovies and sardines, along the coast of Africa.

Fashion makes us feel elegant and affluent, creating unique looks that allow people living in crowded societies to set themselves apart with unique styles. But fashion also comes at a substantial environmental cost. According to many estimates, 10% of the world's carbon emissions and 20% of wastewater are generated by making, shipping, and selling clothing, much of which ends up in landfills long before the clothing's usefulness is exhausted. Meet Kurt Kipka, Chief Impact Officer at the Apparel ...

The volume of electronic waste doubles about every six years as technology plays a more significant role in daily life. In 2019, the United Nations estimated that only 17.4% of electronics were recycled. The United States recycled only 9.4% of its e-waste that year. But in Europe, the recycling rate was 42.5% in 2019. There are many ways to improve, and one is the growing market for refurbished technology. Meet James Murdock, founder and chief marketing officer of Alchemy Global Solutions, a tra...

Electric vehicles are taking market share away from internal combustion competitors, with new plugin vehicle registrations in 2023 growing 45% yearly and accounting for 18% of all vehicle sales worldwide this year. U.S. EV sales hit 7.9% of all new car sales over the past three months. In Silicon Valley-speak, EVs are nearly across the chasm, the point at which a new product category is poised to displace older products rapidly. You're probably asking, "Can I afford one?"

Business may be the most potent force in the world, perhaps more poweful than government. The largest corporations—only 20 companies— are responsible for one-third of carbon emissions, and some firms carry more economic heft than many nations. For example, Apple earned $99 billion in net income in 2022, and if Apple were a nation, it would rank 67th in the world if compared to the GDP of other countries. The Climate Crisis and its related food, water, and immigration impacts present the most sig...

The circular economy is a vision for a world in which the materials used in the products and packaging we purchase flow perpetually through the economy, used over and over instead of being tossed into landfills and replaced with newly mined, refined, and processed stuff. Recycling, an industry with about 50 years of history, is considered an essential feature of the circular economy, but it is just one option. Our guest, Knoxfill founder Michaela Barnett, recently wrote an article for The Conver...
