How much electricity does an industrialized city of 1 million people consume per year?

Answer 1

Per capita energy usage varies A LOT, depending on several factors, including:* The specific country; it may vary by a factor of more than 10 from one country to another.

* Whether you want to include energy used indirectly - for example, by eating food, or using some item, which needed energy to produce industrially.

* Since you are asking specifically about ELECTRICITY and not about ENERGY, that will also depend on whether other alternatives are used - for example, in some cases manufacturing might use fossil fuel, which has energy, but is not technically electricity.

The Wikipedia article "List of countries by energy consumption per capita" tells you how much ENERGY is used per person, in different countries. This is energy, and not electricity. However, energy usage is probably much more interesting, because using a certain amount of tonnes of petroleum is problematic for the environment, whether it is first converted to electricity or burned directly for heating homes, for example.

As an example, for the United States, the article quoted mentions 301 GJ per person per year, so for a million people that would be about 301 PJ (petajoules) - 301,000,000,000,000,000 joules. If you prefer to have that in kWh, you can divide that by 3,600,000. But note, once again, that this is total energy consumption, not "electricity".
