Rerun: 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.

Hip Hop 4 Change: Using Art Activism to Combat Climate Change

Hip Hip is not just a music genre; it was born as a way for the oppressed to speak about and connect over the socio-economic injustices they experienced. In this episode we delve into how today’s youth can use art, including Hip Hop, to engage critically with the world around them. We spoke with Khafre Jay, the founder and executive director of the nonprofit Hip Hop For Change, about how he uses Hip Hop for climate activism.

Resilience Hotspots: Nature’s Role in Urban Climate Adaptation

Nature-based solutions to climate change, such as “Resilience Hotspots,” can enhance climate resilience by restoring and maintaining pockets of nature, such as wetlands and urban green spaces, to counteract storm surges and urban heat islands. Integrating these natural defenses into urban planning, while emphasizing community equity, not only mitigates climate impacts but also promotes climate justice.

Using Mobile Apps to Improve Air Quality Awareness in Ghana, with Dr. Collins Gameli Hodoli

The human health effects of air pollution and climate change can exacerbate each other and some air pollutants, like black carbon, are both hazardous to human health and powerful greenhouse gasses. We spoke with Dr. Collins Gameli Hodoli about the importance of increasing awareness of poor air quality–through the use of a mobile app he developed–to developing policies to improve air quality in Ghana.

Electrifying Motorcycle Taxis in Africa to Reduce Emissions and Save Drivers Money

Electric motorcycles and battery swap technology can improve livelihoods and reduce emissions in Africa and around the world. Ampersand, an African electric vehicle company, provides affordable electric motorcycles (called “e-motos”) in East Africa and operates a convenient battery swap system. These e-motos are replacing polluting gas motorcycles with a cost-effective and environmentally friendly alternative.
