  • Low-carbon cement from farm waste

    Low-carbon cement from farm waste
    2025/01/01
    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.

  • Feeding a Changing World

    Feeding a Changing World
    2024/12/01
    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 strong support from organizations worldwide and has built a robust team of partners and collaborators. Looking ahead, PlantVillage plans to expand how it’s helping farmers while simultaneously addressing climate change.

  • Converting CO2 into fuel

    Converting CO2 into fuel
    2024/10/01
    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.

  • Floating offshore wind energy

    Floating offshore wind energy
    2024/08/01
    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.

  • Evaluating lighting efficiency

    Evaluating lighting efficiency
    2024/07/01
    Before the early 20th century, light measurement lacked a standard, repeatable approach. At that time, scientists developed a spectral sensitivity curve, representing the "average human observer." This graph quantified light output and standardized lamp brightness calculations. Although experts recognized its imperfection and proposed alternatives, this graph, remarkably, remains the standard a century later. On this episode of Growing Impact, we discuss light sources, the measurement of those sources, and how updating this century-old standard could significantly improve energy efficiency.

  • Underground carbon storage

    Underground carbon storage
    2024/06/01
    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.
