 Hi, I'm Diana and I love energy. Do you know that energy isn't everything we do as humans? From our space heating and cooling, from our appliances, our charging our phones, our transportation, it's in everything we do. And we've been teaching students here at Stanford about energy through a course called Understand Energy for over 30 years. And now we're taking the content of that course and bringing it to you and a free and publicly available website. Our Understand Energy Learning Hub lets you get in there and answers your energy questions. Any questions you have about fossil fuels and their impact on the environment, about solar and winds, and how we're managing the variability of those resources. All of that is now being provided to you in an easy to navigate way so that you can learn and answer all of these energy questions. So to get a little insight on that, I'm going to send you over to my friend Ms. Rizzle. So Ms. Rizzle, take it away. Check this out. Somewhere, I just made a power plant provide more electricity to the grid in order to power my laptop. The electricity system is amazing. This system that is providing real-time power, real-time supply and demand has to balance always on our grid. So I want to show you one of those things. This is a Tesla Powerwall battery system and what this is doing is improving the reliability and the flexibility of our electricity grid. So instead of me always having to supply electricity right when I'm demanding it so the power plant has to provide it right when I plug in my laptop computer, now we can have a buffer. Thanks so much Ms. Rizzle and love the dress. Interesting stuff, right? As a mom of four, I am very passionate about what kind of planet we will have in the future. Understanding energy is so important in everything we do in terms of human development, energy equity, justice, and it also is the biggest contributor to some of the big harms that we're doing to our planet. Biggest contributor to climate change, huge contributor to air pollution and human health. It has all of these impacts on us as humans. Our Understand Energy Learning Hub, you can go to the website, it's posted below. We make it fun for you, we have lots of videos and facts and we keep it all updated. Join us in this Understand Energy Learning journey.
