Before learning energy, you would benefit from having a basic understanding of the electrical power system and how power is generated, transmitted, and distributed. If you are familiar with the term “renewable energy” and its components, such as wind energy, solar, and hydroelectric dams, then you may have some of the skills needed to study energy. If you have experience in any capacity in energy science or engineering, you may have several skills necessary to study engineering. Experience in business analytics, business analysis, and economics can also be a beneficial background for studying the power industry.
