No, wind power does not account for less than half a percent of total global energy usage in 2014.

Primary and secondary energy

Primary energy is the energy contained in a fuel. So to speak the released heat in perfect combustion. Unburnt fuel is part of many energy conversion cycles. It is not the generated useful energy.

Non-Fuel based primary energy would be the input to the system, not the generated useful energy. For wind turbines this would be the energy contained in the wind, a perfect wind turbine can only get around 60% of the winds energy (Betz's law). For solar we have around 15-20% conversion efficiency.

Secondary energy is the energy of energy carriers, these are for example fuels and electricity. Fuel can be an input for electricity generation, so even there are subclasses regarding the quality of the secondary energy. (Oil would be primary, gasoline a secondary energy in some regards, even though we don't use all of the energy in gasoline either)


The graphs compare apples to oranges. Primary wind power should get a factor of 2-4, solar power a factor of 5-8 and hydro should also get some factor (but this is more difficult to figure out). I'm not sure how they calculated biomass, so I won't go into that.

The graphs are bad at representing primary energy, as renewables are represented by their secondary energy.

I see no indication in their report that they properly addressed this (important) issue, so I must assume that they didn't.

I'm not sure if they even used coals primary energy or the secondary electrical energy created by the powerplants.

Exaggerated alternative data (just to make a point)

Primary solar energy heats the earth during the whole year, if we assume that heating needs(relative to the avg temperature of space of a few Kelvin) are met by solar power, we get about 99.9+% (didn't calculate it actually) of the primary energy in solar.
