Join Dr. Knowledge as he takes young viewers on a fast-paced adventure to learn about energy and electricity. Shows what tools, appliances, factories, and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. K and the Inquisitive Minds team trace the electricity from the wall through the power grid to its source.
