If we want a better world, we have to get a sense of how much energy it would take. First we look at the status quo, then we envision some hypothetical scenarios.

Methodologies
First we define the scale (X axis) (same for every bar graph):
- 1 pixel = 24 Mtoe/year

The X axis scale for the bar graphs
Status quo
Using data from IEA (international energy agency):
Source (1) has general stats about worldwide total final energy consumption (TFC), and what share of that is used in industry and transport.
Source (2) has more detailed breakdowns for energy usage types, but they are only based on a handful of countries - mostly developed countries (...)( Australia, Belgium, Canada, Czech Republic, Finland, France, Germany, Hungary, Italy, Japan, Korea, Luxembourg, New Zealand, Spain, the United Kingdom and the United States. ).
We use these together, to estimate how energy is used globally.
Industrial: global data from (1)
Transport: take subcategories from (2), scale them to match the global demand in (1)
Residential & Commercial: take subcategories from (2), scale them to match the remainder of global demand in (1)
Non-energy use of fuels: global data from (1)

Note that this is wildly different from industry.energy which is global. That's because a lot of manufacturing happens in poorer countries.
