As cities and populations grow, we need more and more energy to run and heat our homes and to power transportation. Readers will learn how energy engineers help make sure that our energy demands are met in a number of different ways. They discover new ways to convert natural resources into energy, build power stations for both renewable and non-renewable forms of energy, manage electrical power networks, and monitor harm to the planet. Real-life examples and a design challenge show how energy engineers will play a vital role in our future.
