Sometimes when energy is transferred, a force acts which moves something: lifting a book, cycling uphill, walking up stairs, kicking a football. The word 'work' in science has a special meaning. We say that work is done on an object when a force moves that object.
Every second, the Sun radiates 4 x1026 J of energy.
joules per second or
400 billion billion megawatts!
Only a small fraction of this energy actually
reaches the Earth (about 2x1017 joules each
second), but that's still a vast amount of energy.
All the power stations in the world put together
produce less than 0.4% of that!
