Mathematics is often viewed by students as an abstract discipline, detached from the tangible world. However, introductory algebra provides the necessary tools to interpret and predict trends in economics, sociology, and environmental science. Textbooks such as Introductory Algebra by Allen R. Angel emphasize the application of linear equations to real data. This paper applies those principles to the energy sector.
The global energy landscape is currently defined by a race between two competing variables: the declining reliance on fossil fuels and the increasing reliance on renewables. By treating these variables as linear functions of time, we can create a predictive model to answer a vital question: If current trends continue, when will renewable energy capacity overtake fossil fuel capacity?
