Average per capita energy consumption

Here's some interesting info that I didn't mention:

World average per capita energy consumption = ~1745 kgoe/person
World average HDI = 0.76 (higher than I thought)
World average CO2 emissions = 6.5 t CO2/person

The world's population is growing at about 1.2% per year, or 75 million people/year. This means that in order to maintain today's world per capita energy use, we'd have to build the equivalent of 174GW of power capacity (equivalent to roughly 174 nuclear reactors/coal power plants) every year.

So, for Q1 in the article above, we had everybody in the world using 2400kgoe/person and had to build 6700GW to bring everybody's HDI up to 0.9. To account for population increases, we would also have to build roughly 240GW per year on top of this.
