A level 3 Oxford Bookworms Library graded reader. Written for Learners of English by Alex Raynham.

Right now, all over the world, people are using energy. As we drive our cars, work on our computers, or even cook food on a wood fire, we probably do not stop to think about where the energy comes from. But when the gas is gone and there is no more coal – what then? Scientists are finding new answers all the time. Get ready for the children whose running feet make the energy to bring water to their village; for the power station that uses warm and cold water to make energy; for the car that saves energy by growing like a plant . . .

    2 Fossil fuels
    For thousands of years, people made things with their hands. They used the power of the wind, water, and animals to travel, move, or build things. Most people burnt wood to heat their homes and to cook. Then, in October 1765, a young engineer called James Watt built a machine that changed the world – a steam engine.

    To make a steam engine work, coal is burnt to heat water, and this makes steam. The steam goes into the engine and moves the parts inside it. There were steam engines before 1765, but Watt’s new engine worked much better and could move big machines in factories. Soon people began to build factories everywhere.

    2 Combustibles fósiles
    Durante miles de años, la gente hizo cosas con sus manos. Utilizaron la fuerza del viento, el agua y los animales para viajar, mover o construir cosas. La mayoría de la gente quemaba madera para calentar sus casas y para cocinar. Luego, en octubre de 1765, un joven ingeniero llamado James Watt construyó una máquina que cambió el mundo: una máquina de vapor.

    Para hacer funcionar una máquina de vapor, se quema carbón para calentar agua, y esto produce vapor. El vapor entra en la máquina y mueve las partes dentro de ella. Había máquinas de vapor antes de 1765, pero la nueva máquina de Watt funcionaba mucho mejor y podía mover grandes máquinas en las fábricas. Pronto la gente comenzó a construir fábricas en todas partes.
