Renewable energy is a growing interest in the U.S.A, and solar energy is among one of the most popular new energy sources. People have already started to use solar panels on their roofs, so why not their windows? A tech startup has created windows that double as solar panels. When the light shines in through the window, there is a strip of solar cells angled to absorb energy from the sun without restricting your view. We have light that stream through our windows everyday, so why not utilize it.

This relates to engineering, because doing this creates a solution for a problem. We want to have more ways to power our technology, and through many different engineering processes these people created a functional solution. With out the knowledge of mechanical, electrical, and other types of engineering this would not have been possible.
