Using Groundwater to Heat and Cool Buildings


Heat pumps are a more sustainable and efficient way to heat homes than to conventional gas heat, but they’re often too expensive for homeowners to install. Meet the GeoGrid, an underground geothermal heat pump network that could make the technology more efficient and accessible. Home Energy Efficiency Team (HEET) is a nonprofit working with utilities to develop GeoGrids in residential neighborhoods. We spoke to HEET Executive Directors Audrey Schulman and Zeyneb Magavi about heat pumps and the advantage to connecting them via a GeoGrid approach.

Transforming Food Waste Into Vegan Leather with Polybion’s Axel Gómez-Ortigoza


Over the last two decades, vegan leather has grown in popularity. The catch? It’s usually made with polyesters that can’t be recycled. In today’s episode, we speak to the cofounder of biomaterials company Polybion about their carbon neutral leather alternative Celium, which is produced by feeding agricultural waste to bacteria.

Building Tribal Communities’ Energy Independence with Indigenous Energy Initiative


Native communities have disproportionately low access to and pay higher rates for utilities, particularly electricity, which has a significant impact on access and opportunities for remote work, education, and other activities. The Indigenous Energy Initiative works to increase indigenous energy ownership and access in order to address the social, economic, and environmental injustices that native communities face. This week, Chéri Smith, founder and CEO of IEI, discusses their strategy for assisting indigenous communities and eliminating energy poverty.

Bringing Local Textile Recycling to the US with Material Return’s Bobby Carswell


The textile industry produces up to 10% of global emissions and 20% of global wastewater, according to EU estimates. Mechanical recycling can reduce that impact by keeping textiles out of landfills — and in the circular economy — for longer. In this episode, Climate Break spoke to Bobby Carswell about Material Return about how locally based mechanical recycling can help make the US textile industry more circular and less polluting.

Could Windows Be A Source of Solar Power? with Professor Stephen Forrest


Office buildings, high rises, and greenhouses are covered in windows. What if we used all that window space to capture solar energy and add to the grid’s renewable energy supply? Listen to University of Michigan engineering professor Steven Forrest explain how a change in the semiconducors used in solar panels could allow us to transform windows into power sources — without sacrificing light and transparency.

Using CRISPR to Fight Climate Change with Professor Kris Niyogi


When plants photosynthesize, they temporarily remove carbon dioxide from the atmosphere. Could we use gene editing technology CRISPR to enhance photosynthesis and increase the amount of carbon dioxide they remove? UC Berkeley biology Professor and photosynthesis expert Kris Niyogi thinks so, and he says it could fight climate change and enhance food production at the same time. In this episode, Climate Break speaks to Professor Niyogi about his lab’s early-stage research into CRISPR, photosynthesis, and applications to climate change.

Using Carbon Emissions Registries to Reduce Emissions with Dan Krekelberg


When emissions aren’t tracked, it’s harder for organizations to see how they can reduce their carbon footprints. Climate Break spoke with Dan Krekelberg, policy director of Climate Registry, about how centralizing emissions data can help organizations and agencies track and reduce their greenhouse gas emissions.

Electric Vehicle Retrofitting with Dr. Aly El Tayeb


To decarbonize transportation, we’ll need to switch to electric cars. New electric vehicles are decreasing in price and increasing in range and accessibility, but remain out of reach for many. Could EV Retrofitting, a process that converts cars from internal combustion to electric in just a few hours, be what fills in the gap? Listen to Climate Break talk to Dr. Aly El Tayeb, founder of Egyptian retrofitting startup EV Shift, about its potential.

What Advanced Clean Cars II Means for Zero Emission Vehicles with Dr. Steve Cliff


The California Air Resources Board’s Advanced Clean Cars II Rule requires all new light duty vehicles sold in California to be zero-emission by 2035. In the final episode of our series with CARB Executive Officer Dr. Steve Cliff, Climate Break talks to Dr. Cliff about CARB’s approach — and why he thinks the time is right for an ambitious government mandate.
