ATP is often used as the source of energy during active transport.
Yes, any form of active transport uses energy.
The source of the energy used in active transport is the electrochemical gradient. Another possible source of energy for active transport is the breakdown of ATP molecules.

I think because passive transport doesn't require energy and active does.
