Active transport requires energy because you are going against a gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.

One example of passive transportation is a river. Floating downstream does not require any energy. You are simply moving with the gradient. If you wanted to go upstream, you would have to paddle. This requires an input of energy similar to active transport.
