<p>I am aspiring to do the same exact thing. I am going to major in Mechanical Engineering, with a focus on sustainability and renewable energy production. Schools (I know Cornell does for sure) have specific courses on renewable energy that fit into the engineering curriculum very nicely. Other schools to look at: Cal, Northwestern, Duke. </p>
<p>I suggest going onto your school’s engineering department website, and look for “course offerings.” </p>
<p>Find courses that focus on renewable energy, such as this one from Northwestern, which I plan on taking if I enroll:</p>
<p>"Title: Introduction to Energy Systems 21st Century</p>
<p>Number: ISEN 210</p>
<p>Time: Mondays, Wednesdays, and Friday, 1-1:50</p>
<p>Description: This survey course provides an overview of energy issues in the context of climate change and global sustainability. Energy demands for industrial, transportation, housing, and commercial uses are presented, and strategies for demand reduction are discussed. Energy supply is presented from the points of view both of largely mature technologies (fossil and nuclear fuels, hydro power) and of upcoming renewable sources (solar, wind, geothermal, wave and tidal, and biofuels). Issues associated with energy storage (batteries) and transport (smart net) are discussed, with particular emphasis on the hydrogen economy. While this course will address many technical and scientific aspects of energy, no prerequisite technical courses are required from students. Guest lecturers will present other non-technical facets of the energy topic, including social, legal, and economic issues.</p>
<p>Prerequisites: none - freshmen and non-majors are very welcome"</p>
<p>I think these are the kind of classes you are looking for.</p>
