CleanTech Explained is an independent guide to clean energy technology. We explain how solar panels, home batteries, electric vehicles and the materials behind them actually work, without the hype.
What we cover
Our guides help homeowners, engineers, buyers and investors make better decisions about clean energy:
Solar: sizing, costs and panel types for homeowners.
Home batteries and power stations: backup power and battery chemistries.
EVs and charging: home chargers, running costs and battery life.
Magnets and materials: rare earth magnet alternatives and rare-earth-free motors.
Critical minerals: lithium, nickel, cobalt, rare earths and the supply chains behind them.
Who is behind CleanTech Explained
CleanTech Explained was founded by Dagus R Djuanda, a metallurgical engineer with more than 20 years of experience in materials engineering, and specializing in magnetic materials.
Dagus holds a master’s degree in magnetic materials engineering and is a doctoral candidate in industrial engineering. He works as an engineer at the Ministry of Industry of the Republic of Indonesia, where his work connects materials science with industrial policy and manufacturing. This combination of hands-on materials expertise and industry experience shapes how CleanTech Explained covers everything from rare earth magnet alternatives to the critical minerals behind batteries and EVs.
He studied rare earth magnets at Pukyong National University in South Korea, and several of our magnet guides include measurements and photos from magnets he made there.
Working with magnetic materials, he saw firsthand how much the world’s clean energy future depends on a small number of materials, and how rarely that story is explained clearly. He started CleanTech Explained to close that gap, making the technology behind solar, batteries, EVs and their materials understandable for everyone.
The views on this site are his own and do not represent the Ministry of Industry or the Government of Indonesia.
