The ski mountain that is about ten miles down the road from where I live has a large array of solar panels. Their goal is to use as much renewable energy as possible. To that end, another solar array is being constructed about a mile down the road. I noticed the progress earlier this week when I drove past it. That got me thinking about how many solar panels will be needed and it prompted me to look in my archives for some resources for teaching about how electricity is generated. Here are a few that I picked out.
Idaho Power offers a short video overview of how hydroelectric dams generate electricity and the process of getting that electricity from a dam to a house. Before you show this video to your students, it might be worth pointing out to them who produced and why they produced it.
