Why Do We Need To Know About Sun

Learning about the sun helps us know how it changes our environment. Knowing how to use sunlight for power is key for jobs in renewable energy. It also matters in making cities and buildings, where the goal is to use light and heat well to save energy and make places comfortable.

It’s also important for people who pick materials for buildings and outside areas to understand which materials are best for blocking the sun and saving energy. This is useful for jobs in building things, designing eco-friendly buildings, and creating outdoor spaces.
