Did you know that all of the uranium on Earth was formed in exploding stars about 6.6 billion years ago? We depend on energy from the world around us to make electricity and fuel. We collect it from places where it's stored, as fuels like uranium or oil buried deep underground. Or we catch it as it passes, like the energy in flowing water or the wind. Try our quiz on energy. See if you can get 10 out of 10. Along the way you can also visit some bonus stuff: games, animations and stories from around the world.
Did you know that washing a pair of pants again and again during its lifetime uses more energy than making it in the first place?
Without energy on tap, life would be very different. Energy is costly to capture, easy to waste and using it to make electricity and fuel takes its toll on the planet. The world's favourite energy stores are fossil fuels. Now we're under pressure to cut back and clean up.
Here's the challenge: future energy supplies must deliver enough to power all our lives, without unnecessary damage to the planet. We can't rely on fossil fuels for ever - but different places will need different energy alternatives. By joining the debate we can all help to get power to the people.
