The data comes from Wikipedia with most figures coming from 2016 (you see the full list there).
Average power per capita was calculated according to the formula:
Electric energy per capita [ in watt-hour ] = Total population electricity consumption [ in kW·h/yr ] * 1,000 /population.
Electric power per capita [ in watt ] = Total population electricity consumption [ in kW·h/yr ] * 0.114077116 /population.
1 kW·h/yr = 1,000 Wh/(365.25 x 24)h = 0.11408 Watt
Overall, China is the world’s largest consumer of electricity, but given it’s vast population, the figure per capita is only 510 watts. The US is the second largest consumer in aggregate, but the per person figure is much higher at 1,377 watts.
Finally, the UK is the world’s 11th largest consumer of electricity in total, with a per capita consumption only slightly above China’s at 547 watts.
