This inspiring book describes how people are becoming more aware of the effect of their daily activities on the planet. Find out how more and more people are eating and living "green" by buying food grown locally, eating food that is organic, and even growing their own food. Many people are also building eco-friendly homes and choosing to live “off the grid,” which means they are creating their own, sustainable forms of energy instead of getting electricity from a power station. Discover how eating and living green is becoming more and more possible, and why this way of living could help build a sustainable future for the next generation.
From trees and plants to bugs and birds, every living thing on Earth is a form of energy. And all living organisms create energy, too, in the form of their waste. The energy of living things is called biomass, and it can be used to power the things that we need in our everyday lives, from washing machines, cars, and computers to the heating and lighting used in our buildings. Find out more about biomass, how it is sourced and used, and why this form of energy could help us find a more sustainable way to power our lives in the future.
How are many people in different places around the world learning to live in a green and sustainable way? Find out how human activities such as driving cars and wasting energy are threatening our environment and putting the future of our planet at risk. Discover how people everywhere are choosing to live more sustainably by recycling, using green sources of energy, car-sharing, and reducing air travel.
We live in an energy-rich age, in which we can turn on a light with the flick of a switch or drive anywhere by turning a key. But, our vehicles, factories, and power stations, which create the electricity needed to light and heat our buildings, pump carbon dioxide into Earth’s atmosphere. Carbon dioxide overload from these human activities is making our planet hotter and hotter - and is causing the Earth's climate to change. Find out what scientists are doing to find sustainable new forms of energy that will secure our planet’s future.
Earth has a limited supply of fossil fuels, and in the near future this supply will come to an end. However, more people live on the planet than ever in its history - and they all need energy. One of the ways in which we can meet this increasing demand for energy is through nuclear power. Nuclear power stations do not drain our planet of its resources, and they can supply a seemingly limitless source of energy. Discover more about nuclear energy, how it is created and harnessed, and the controversies and challenges that surround it.

Our planet’s weather offers some incredible solutions to our growing energy needs, and one of those solutions is wind power. Offshore and onshore wind farms are an increasingly familiar sight in many countries around the world. Wind farms tap into this clean, sustainable, and renewable form of energy. Find out how wind power works, where in the world it is being used, and how this green energy supply could be one answer to the energy problems that face us today.
Beneath Earth’s surface is a boundless source of energy - geothermal energy. Heated by our planet’s red-hot core, hot water and hot rock below the ground on which we walk already provides energy in many parts of the world, from Alaska to Hawaii. Discover the different forms of geothermal energy, how people are harnessing and using this rich supply, and how it could be an important part of our energy future.
