Power is energy in unit time.Estimate the time in which energy is being expended and that amount of energy.

But how about energy?

How can I estimate energy?

Unfortunately,u can't estimate the real energy involved,namely the energy released from the chemical reactions that take place in your body while u're climbing that ladder.But you can approximate (i don't know how accurate,though) that with the work done by your body against gravity (equivalently,the variation in gravitational potential energy of your body),assuming you climb at constant speed wrt the ground...
