Since you didn't include sources, and got your units all confused, I figured I'd try to rewrite some of this.
We'll use the United States as a model, as it will give us the "worst-case". The US Population is about [323 million][Population Clock], and we consume about [3,900 TWh/year][US Electricity Consumption] across all sectors - so the per-capita demand for a US citizen and all the support she requires to live, is about 12 MWh/year. For our city of 100,000, therefore, we'll need about 1.2 TWh/year of clean energy.
