power = energy/time. So that we have: energy = power × time. In this formula, energy is measured in joules, time is measured in seconds and power in watts. Therefore to calculate the energy consumption of using a 1000 W microwave, we can calculate it as follows: energy = power × time. = 1000 W × 60 s. = 60 000 J.
