Wind Energy and Power Concepts

Jessica introduces the One Energy Science Shorts series, focusing on the difference between power and energy. Using Carly's hand-raising demonstration, she explains that energy is the ability to do work, while power is the rate of doing work. A lamp example further illustrates these concepts. The video also covers how wind turbines convert wind energy into electrical energy, emphasizing the importance of understanding these terms in the context of renewable energy. The video concludes with a recap and a reminder to challenge everything, except bears.
