Growing Impact is a podcast by the Institute of Energy and Environment (IEE) that explores cutting-edge projects of researchers and scientists who are solving some of the world's most challenging energy and environmental issues. Each project has been funded through the IEE Seed Grant Program.
Growing Impact: Evaluating lighting efficiency

Lacking a standard unit for light measurement, scientists devised a spectral sensitivity curve in the early 20th century. This graph, representing an "average human observer," mathematically quantifies light. Though imperfect, it remains the standard today, but an update could significantly improve the energy efficiency of lighting.
Growing Impact: Underground carbon storage

Storing carbon dioxide underground could offset the record amounts of CO2 that humans emit each year. If this technology is successful, it could be an answer to climate change impacts, such as rising temperatures and acidification of the ocean. However, the process is complex and costly. A team of researchers is exploring one way liquid CO2 could be injected into rock formations, which may efficiently convert the molecule into a solid.
Growing Impact: Investigating thawing permafrost

Once a frozen haven, climate-driven rising temperatures are rapidly thawing the Arctic permafrost, posing a major threat to communities and infrastructure. Researchers are investigating how these changes will transform rivers, with potential consequences for erosion, sediment transport, and the entire Arctic landscape. Additionally, their project incorporates art to communicate these critical findings in an engaging way.

The global push to involve youth in climate action is gaining momentum, harnessing their innovative spirit, deep investment in the future, and strong collective voice to combat climate change. Getting young people involved ensures that climate policies are forward-thinking and geared towards sustainable development, while their global solidarity and use of digital platforms amplify the call for urgent action. At the forefront of this movement, Penn State's Global Youth Storytelling and Research Lab aims to become a pivotal transnational research hub, empowering young leaders to shape the future of climate and environmental justice.

For decades, PFAS (per- and polyfluoroalkyl substances) have been a staple in products from detergents to cosmetics, making items more durable and resistant to water and stains. However, these "forever chemicals" persist in the environment and are now ubiquitous, even in our drinking water. Emerging evidence links PFAS exposure to significant health risks, prompting a team of researchers to evaluate affordable filtration technology, especially in communities reliant on well water.

Solar energy's surge, driven by cost efficiency and climate change urgency, is prompting a rapid transition to a renewable energy source with substantial land requirements. To inform just and sustainable rural land use with solar, a research team is working in rural communities to determine the potential for harmonious coexistence between solar and agriculture.

The Colorado River supports more than a trillion dollars in economic activity and supplies water to an estimated 40 million people. The overuse of the Colorado River and an extensive climate change-driven drought have significantly decreased the volume of the fifth largest river in the U.S. A research team is exploring how climate change and agricultural adaptation will affect water availability in the Upper Colorado River Basin and what is important to communities that depend on the river.

Contrails are the second largest contributor to aviation's impact on climate change after carbon dioxide emissions from fuel burn. A new interdisciplinary project looks to identify opportunities to mitigate the climate impacts of contrails as the number of people flying is anticipated to grow in the coming years.

Malawi is facing environmental challenges including deforestation, soil erosion, and unsustainable farming practices. While Malawi has pledged to restore degraded lands, it is not clear if any efforts are accomplishing what they intended. A research group is using Malawi as a case study to better inform policies and practices in forest landscape restoration.

With rising energy costs and the worsening climate crisis, some wastewater treatment plants have started using solar energy. However, solar adoption at wastewater treatment plants is still relatively new, and there is little known about these facilities, including where they are, what drove them to choose solar, and if solar has been a success. A team of researchers looks to fill in those gaps with a new project.
