Introduction to Energy – Video
Summary
Introduction to Energy
This video introduces students to the concept of energy and explains why energy is fundamental to nearly every part of modern life. From transportation and communication to food production and manufacturing, energy powers the systems that support daily activities around the world.
Students learn that energy is used constantly, often in ways that are easy to overlook. Cars, heating and cooling systems, computers, and household appliances all rely on energy to operate. Even products we use every day require energy throughout their lifecycle, from manufacturing and transportation to use and disposal.
The video also highlights how energy supports global supply chains. Goods are produced in factories, transported by ships, trains, trucks, or airplanes, and delivered to homes and businesses. Each step requires energy to power equipment, machinery, and transportation systems.
Students explore how energy is also deeply connected to food production. Modern agriculture relies on energy for planting, harvesting, processing, packaging, transporting, and preparing food. These processes allow food to move from farms to stores and ultimately to households.
By examining the many ways energy supports modern life, students gain a broader understanding of how energy systems influence economies, infrastructure, and everyday activities. The video encourages students to recognize how energy use connects to larger discussions about technology, resources, and the future of global energy systems.
This resource supports lessons on energy systems, physical science, environmental science, and global development, helping students understand the role energy plays in shaping modern society.

[Dr. Scott W. Tinker] Most of the time, we’re too caught up in modern life to realize that energy makes it all possible. There are obvious things, like our cars, we know those are powered by energy, but everything else is, too. The Internet, all phone systems, every appliance, air conditioning and heating, everything in our offices and houses, even while we sleep. We consume energy 24 hours a day. Every single product we buy, like a pair of blue jeans, requires energy. From the time it’s made in a factory, washed, and dried, and worn, and eventually discarded, a pair of jeans uses the equivalent of three gallons of gasoline. You might have 50 gallons of gas in your closet from your blue jeans alone, and it’s not just jeans. Every product is made somewhere, then moved by ship, train, truck, car, sometimes all four, from the factory to your house. Each of those steps is powered by energy. Even things we don’t think about like our food are only made possible today by energy. It’s planted, harvested, processed, packaged, transported, retailed, and bought using energy all along the way, huge amounts of energy. In your weekly shopping cart of groceries, there’s the equivalent of 22 gallons of gasoline, and then, you’ve got to cook it. Everything we do in our lives from the time we’re born through every day of every year depends on energy. Every home, every business, every government, every major issue is underpinned by energy, which is why energy is the most important issue of our time, and by joining the discussion and sharing these videos with your friends, you can help us move forward toward a smarter energy future.
