                     :power_usage_effectiveness => 1.5, # based on Amazon's EC2 cost comparison calculator statement that most data centers have PUE of 1.3 - 3.0
                     :electricity_intensity     => 0.075 # kW based on Amazon's EC2 cost comparison calculator stating 150W for small compute instance equivalent server and 0.5 power conversion factor (to get average operating load from nameplate capacity) - EC2 probably has lower draw but higher power conversion factor
