Free online courseRenewable Energy Engineering

Course Description

Renewable energy projects succeed when engineering decisions are backed by solid fundamentals, realistic assumptions, and the ability to translate natural resources into usable heat and power. This free online course helps you build that foundation across three major renewable pathways: solar thermal energy, biomass conversion, and wind energy. Designed within Professional Skills and grounded in Mechanical and Industrial Basics, it connects theory to the kind of calculations and design thinking used in real-world applications.

You will learn how solar radiation behaves, why orientation and angle of incidence matter, and how different collector types change performance. Instead of stopping at concepts, the course repeatedly reinforces understanding through worked-style practice that develops confidence with energy balances, useful heat gain, temperature rise, and key performance parameters. You will also explore concentrating approaches such as parabolic collectors, along with practical limitations and trade-offs, then move into thermal energy storage ideas that help renewable systems deliver energy more reliably.

On the biomass side, you will build a clear picture of how composition and properties influence conversion choices, including how heating values are interpreted for fuels. The course explains biochemical and thermochemical routes in a way that supports engineering judgment: when anaerobic digestion makes sense, how biogas systems are categorized, and why feedstock selection affects output. You will also examine combustion, gasification, torrefaction, liquefaction, and pyrolysis, with problem-solving that ties process parameters to usable energy, daily requirements, and practical system sizing.

Wind energy rounds out the curriculum by clarifying turbine terminology, basic theory, and how power extraction is limited by fundamental principles. You will connect concepts such as torque and tip speed ratio to performance and efficiency, building intuition for how turbines are analyzed and compared. By the end, you will be able to approach renewable energy engineering problems with a structured method, a stronger quantitative toolkit, and the vocabulary needed to communicate confidently in clean-energy settings.
