Unlike fossil fuels, renewable resources naturally replenish themselves. The five major types of renewable resources are biomass, geothermal, wind, water, and solar power. All of these are produced within the course of Earth’s biological cycles. Sunlight, for instance, does not need to be “extracted”; it shines over all parts of the planet, supplying stores of usable energy. Renewable resources do not release harmful pollutants into the air, and they are much better for the long-term health of the Earth. This book explores the five major renewable resources: their histories, how they are captured and converted for human use, and their benefits and potential drawbacks. Humankind still has a long way to go in shaping a more sustainable future. It is hoped that some of the information contained here will help you—the next generation of energy consumers—see a better way forward.
