For context I am thinking about building an Eco house or perusing green entrepreneurship in the next few years.<p>Right now I am considering one of these two:<p>https://www.edx.org/course/circular-economy-an-introduction-2<p>https://www.edx.org/course/incorporating-renewable-energy-in-electricity-grids-2<p>But I'm looking for something with an application ideally business or engineering related. Has anyone done something similar or heard good things about a specific course?
