Put simply, it is a capacity to do work, which in turn is the moving of something over a distance. So your muscles can generate energy by burning metabolites and pedalling a bicycle.
That is a bit oversimplified though when you consider the different kinds of energy. There is
- potential energy, possessed by something, which can be released. The most obvious example is an elevated object which can fall.
- kinetic energy, such as a speeding car which can knock down a pole
- electric energy, a combination of voltage and current
- nuclear energy, bound up in the atom
and others too
