The Amazon, home to rich biodiversity and vital carbon-storing ecosystems, is also the ancestral land of Indigenous communities who are grappling with the devastating effects of oil extraction across Ecuador, Peru, and Colombia. These communities live amid widespread pollution from oil spills, toxic chemicals, and industrial infrastructure, which threaten their way of life and the health of their environment. In response, they are working alongside researchers to map the environmental destruction and strengthen their efforts to hold oil companies accountable while fighting to protect their lands and preserve their cultural heritage.

Nitrous oxide is a potent greenhouse gas with nearly 300 times the warming potential of carbon dioxide, making even small emissions highly impactful. Agriculture, particularly soil management, is the largest source of nitrous oxide. To better understand and manage these emissions, researchers have developed a system for continuous monitoring on farms and other land management purposes.

PFAS, synthetic chemicals found in countless everyday products, have made their way into humans and animals around the globe. Although their health effects remain unclear, their widespread presence raises important questions. Scientists are now investigating whether these chemicals might disrupt the human gut microbiome, potentially impacting our health in unexpected ways.

The Earth can shift suddenly, with sinkholes and landslides posing serious risks to people and property. Scientists are now using existing fiber optic cables in cities to detect potential geohazards before they strike. This innovative approach is expanding to monitor flooding and even track human movement, unlocking new possibilities for data collection and understanding our world.

Cement, a major component of concrete, is a significant contributor to global carbon emissions. Researchers are exploring agricultural waste as a potential alternative to cement, aiming to reduce carbon footprint while also finding new uses for farm byproducts. However, the feasibility and effectiveness of this solution depend on the collaboration between researchers and farming communities.

Smallholder farmers are the unsung heroes of our food system. Tilling tiny plots, they produce a staggering one-third of the world’s food and up to 80% of the food supply in regions like sub-Saharan Africa and Asia. But these vital contributors face immense challenges: such as climate change, pests, insufficient finances, and limited education and training. On this episode of Growing Impact, we’re revisiting the story of PlantVillage, a project funded as a seed grant by IEE in 2016. Its aim was to empower smallholder farmers with knowledge through smartphones and machine learning. Since its creation, PlantVillage has gained stro...

Flooding is the world's most devastating natural disaster, causing widespread destruction and loss of life. Millions of Americans live in high-risk flood zones, with the threat amplified by climate change and aging infrastructure. This episode explores how innovative computer modeling and visualizations can help communities plan for future flood risks and develop effective response strategies.

Carbon dioxide (CO2) is abundant and stable, making it difficult to convert into something useful without a lot of energy. Researchers are using advanced computational modeling to find a catalyst that can efficiently transform CO2 into valuable products. This could turn CO2 from a climate issue into a valuable resource.

Our planet is at a critical crossroads. In Season 5 of Growing Impact, we delve into groundbreaking research with the power to transform our world. This season offers a deep dive into the vast and varied research at Penn State, showcasing its pivotal role in advancing a healthier planet and improving the well-being of people everywhere.

Growing Impact is a podcast by the Institute of Energy and the Environment at Penn State. Each episode explores cutting-edge projects of researchers and scientists who are solving some of the world's most challenging energy and environmental issues. 

Wind power has come a long way from its humble beginnings as water pumps and windmills. Today, it's a major contributor to our electricity generation. While onshore wind farms are well-established, the U.S. has yet to tap into the full potential of offshore wind. With advancements like floating turbines and improved blade designs, wind energy is poised for another significant leap forward.
