For comparsion, your research the power requirments of the minimum number of devices. Approximatley how many watts does your new department draw and what precentage could you reduce your departments energy usage by switching to cloud computing?

Explanation / Answer

energy drawn =10*250+2*250+2*250+250+600=4350 watt
