SUSTAINABLE WORLD
Energy

We use energy every day; from powering our vehicles and factories to heating and lighting our homes, schools and offices. These needs are met mainly by stores of energy, such as coal and oil, which were built up over millions of years. Today, we are using these stores very rapidly, much faster than they can be replaced or renewed. These sources of energy are also very polluting and are known to contribute to global warming.

This book considers examples from across the world that show there are alternative, sustainable ways to provide energy, without damaging the environment. These alternatives are known as sustainable energy, or renewable sources, and their use is growing rapidly as people become aware of the dangers of ignoring the energy problem. It also suggests some choices the reader can make to ensure a sustainable future.
