Rang Dong Develops Green Energy Solutions For More Comfort

Green energy solutions are pivotal for sustainable development in Vietnam, one of Southeast Asian fastest-growing economies, as they offer a pathway to reduce carbon emissions, lower operational costs and enhance energy independence. But the transition towards green energy involves overcoming many challenges. Rang Dong, fully known as Rang Dong Light Source and Vacuum Flask Joint Stock Company, has been leading the process it launched in October 2024 as the “dual transformation” strategy. By integrating digital innovation with green technology, the Hanoi-based company delivers high-performance, eco-friendly solutions tailored for households, businesses, schools and public institutions across the country. 

“Green energy solutions are not about compromising convenience,” said Rang Dong’s Deputy General Director Nguyen Hoang Kien. “Our smart systems ensure a comfortable, modern lifestyle while significantly reducing energy waste.”  

Following the 2020-2024 period of undergoing the digital transformation, Rang Dong, a leading provider of smart lighting solutions with over six decades of expertise and a robust nationwide presence, has developed a comprehensive green energy ecosystem.  

It includes energy-efficient lighting, renewable energy systems and Artificial Intelligence (AI)-powered smart solutions, all are aimed at providing reliability, cost-effectiveness and significant environmental benefits while meeting stringent Vietnamese and international standards. 

Cutting-Edge Green Solutions 

Rang Dong’s green energy solutions are engineered to address diverse needs, from urban residential complexes to rural educational facilities. The company’s flagship offerings ranges from LED products to solar-powered and smart systems. 

High-efficiency LED lighting: Achieving 170–190 lumens per watt, the lights reduce energy consumption by up to 70 percent compared to traditional systems, making them ideal for large-scale applications like schools and offices.  

Solar-powered systems: Solar streetlights, rooftop solar panels, and portable solar devices are among Rang Dong’s products which provide reliable renewable energy, particularly in remote areas with limited grid access.  

IoT and AI-based smart systems: Leveraging Internet of Things (IoT) platforms and artificial intelligence, Rang Dong’s smart home and building solutions optimize energy usage, delivering an additional 30–40 percent energy savings while maintaining modern comfort levels. 

By integrating advanced technologies, Rang Dong enables users to achieve sustainability without sacrificing functionality, making green energy accessible to all. 

Overcoming Challenges 

Undertaking the transformation to achieve its mission in advancing green energy solutions, Rang Dong has been facing, and seeking ways to overcome multiple hurdles. The challenges ranges from technology and infrastructure to regulatory framework and financing. 

Technological barriers: Developing cutting-edge products requires mastery of complex technologies like AI and renewable energy systems. Vietnam is facing a shortage of specialized experts in these fields.  

In order to overcome the problem, Rang Dong has established research centers, collaborates with foreign experts and partners with universities to train young talents, starting as early as their third year of study.  

Infrastructure limitations: Vietnam’s abundant renewable energy potential is hindered by inadequate transmission infrastructure. Recent cuts of 364 GW due to grid limitations highlight the urgent need for investment in the country’s power transmission networks to support green energy growth.  

Regulatory gaps: A lack of comprehensive standards for new energy products, such as solar-powered lighting, creates a chaotic market. Low-quality, low-cost alternatives often compete unfairly with high-performance solutions. Rang Dong advocates for clearer regulations to guide consumers and promote fair competition.  

Financial constraints: Transitioning to green production demands substantial long-term investment. Loan interest rates of 8–12 percent as of August 2025 deter enterprises from scaling up.  

Rang Dong has called for preferential loan programs with rates of 3–5 percent, with support by coordinated policies from the Finance Ministry and the State Bank of Vietnam, or the country’s central bank. 

Rang Dong’s commitment extends beyond product development. The company provides end-to-end services, including detailed site assessments, custom system designs using advanced simulation software, professional installation and strong after-sales support.  

With warranties ranging between 24 and 36 months, along with annual performance evaluations, Rang Dong aims to deliver efficient and reliable product systems. 

Additionally, the company is proactively addressing future challenges, such as battery recycling for solar and electric vehicle systems, by investing in research to develop sustainable waste management solutions. 

For Sustainable Future 

Thanks to the strategic partnerships with the Science and Technology Ministry and international organizations such as the Asian Development Bank, Rang Dong delivers green energy solutions that meet rigorous technical and environmental standards.  

The collaborations have enabled the company to execute large-scale projects with precision, timely delivery and compliance with global benchmarks.   

By adopting Rang Dong’s green energy solutions, businesses, schools and households can significantly reduce energy costs, enhance operational efficiency and contribute to Vietnam’s environmental goals.  

These solutions empower communities to embrace sustainability while enjoying the benefits of modern technology, paving the way for a greener, more resilient future.
