Green Energy and Agricultural Innovation

At CAS Energy, Tu Nguyen works to transform traditional farming systems into climate‑smart, circular agricultural ecosystems. By combining solar power with aquaculture, crop cultivation, and livestock production on the same land, she helps create regenerative, resource‑efficient systems that reduce carbon emissions, resolve land‑use conflicts, and provide clean energy for farming. Under her leadership, CAS Energy aims to reduce over 1.5 million tons of CO₂ emissions annually by 2030, while increasing farmer incomes by 30% and delivering affordable, clean food to 16 million people.

Growing up in Vietnam - a country deeply rooted in agriculture and increasingly affected by climate change - Tu Nguyen developed a strong commitment to building solutions that serve local communities. She holds a degree in Telecommunications Engineering from Danang University of Technology (2002 - 2007), graduating with a “Good” classification. Her career began in technical engineering roles before she founded her own business and transitioned into the automation and renewable energy sectors.

In her role at CAS Energy, Tu Nguyen leads project development, cross‑sector collaboration, financing, communication, and negotiation with a strong focus on inclusive growth. She is particularly dedicated to empowering rural communities, women, and vulnerable groups by creating sustainable livelihoods through green energy and agricultural innovation.

Her work and leadership have been recognized internationally. She has participated in and received distinctions from several global programs, including:

• APEC Catalyst (USA)
• Leaders in Innovation Fellowships (LIF)
• First Runner‑Up, UN Women 2024 Asia‑Pacific WEPs Awards, honoring companies advancing gender equality in line with the Women’s Empowerment Principles
• Vital Voices Global Fellowship, connecting leaders in social entrepreneurship and public leadership to drive inclusive and sustainable solutions

Through her work at CAS Energy and the Circular AgriSolar Farm initiative, Tu Nguyen is committed to driving an inclusive green transition that delivers lasting environmental, economic, and social impact.

Growing up in Vietnam, how did your background shape your understanding of agriculture and rural livelihoods?

Growing up in Vietnam, my background has deeply shaped how I view agriculture and rural livelihoods. My grandparents lived in the countryside, and whenever I visited them, I would pass through vast fields. Those experiences made me very familiar and comfortable with rural life from a young age.

At the same time, I also saw the challenges the rural areas faced. The rural economy was still developing, incomes were relatively low, and livelihoods needed improvement. This gave me a deeper appreciation of both the importance of agriculture and the need for more sustainable, automated, and innovative solutions to support rural communities - helping them achieve higher productivity, better income, and an improved quality of life.

How does integrating solar energy with aquaculture, crops, and livestock benefit farmers on a practical level?

Integrating solar energy with aquaculture, crops, and livestock - what CAS Energy develops through its AgriSolar model - brings very practical benefits for farmers. 

• First, it creates an additional and stable income stream from solar power generation, so farmers are not relying solely on seasonal agricultural yields. This helps reduce financial risk.
• Second, the solar panels can improve farming conditions. For crops, they provide partial shading, which can reduce heat stress and water evaporation. For aquaculture, panels help stabilize water temperature and limit algae growth. For livestock, they offer shelter from extreme weather.
• Third, AgriSolar makes better use of the same land. Instead of choosing between farming or energy production, farmers can do both at the same land.
• Finally, it lowers energy costs. Farmers can use the generated electricity for irrigation, aeration, or farm operations, reducing dependence on the grid and improving long-term sustainability.

Overall, AgriSolar approach helps farmers increase income, reduce costs, and make their operations more resilient and sustainable.

How do you ensure women farmers benefit directly from climate‑smart agricultural systems?

We ensure women farmers benefit from climate-smart agriculture by prioritizing inclusion at every stage, from design to implementation. We engage women in decision-making, design practical and accessible systems that reduce manual labor, and provide training to build their capacity to use technologies like AgriSolar. We also focus on creating direct financial benefits - such as stable income from the project - to support economic independence. At the same time, we work with local partners to ensure fair access to land, financing, and opportunities, so women are true beneficiaries, not just participants.

What advice would you give to young women who want to work in agriculture, climate innovation, or renewable energy?

Start by building a strong foundation in what you’re passionate about and stay open to learning - whether in technical skills or business and project development, depending on your interests.

Don’t be afraid to step forward. Your perspective matters, especially in fields like agriculture and climate solutions that directly impact communities and livelihoods.

Expand your network and gain real-world experience through internships, fieldwork, or projects. This will help you understand practical challenges and build confidence.

Finally, focus on impact. Agriculture, climate innovation, and renewable energy are not just careers - they are opportunities to create meaningful change.
