The study of renewable energy engineering addresses problems associated with the use of fossil fuels by replacing them with sustainable, green options. By exploring different renewable energy types, students often seek to engineer machines or develop methods that are more efficient at producing large amounts of energy.

A bachelor's degree is given to students who fulfill the necessary requirements given by the college or university they are attending. The requirements include three to seven years of focus on a subject, typically referred to as a major or concentration.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
