Everything about energy production and storage.

I think the IEA chart looks into where the energy began, not what it was used for. The 50% number rings true to me, at least for the heating in cold winters. As for summers, cooling is a heat issue as well, so that's where much of the energy is spent.
The International Energy Agency chart is clearly about final consumption. This is why the pie chart seemed so weird to me, not including industries I mean.
