This series explores alternative energy resources, how they are produced, the technology necessary and what the future holds. With global warming and climate crisis and the rise in energy prices, looking at more sustainable types of energy resources, how well they can meet our power needs and how they work has never felt so relevant. Water power comes in many different forms. We can harness the tides, the waves or the flow of a river. How do we harness the energy made by water? What's needed and can it fulfil our energy needs? And what are the risks and benefits? While new technologies are being developed, each energy resource comes at a cost. This series looks at each energy resource, the technology and cost of how it is used to meet power needs and how it impacts the environment and humans. Each book explains how that power is generated and where it is used through clear diagrams and beautiful illustrations. Suitable for readers aged 9+.
