Page 107: "among the direct sources, which account for 33% of the total, are natural gas and, to a lesser extent, other liquid fuels such as oil, LPG and diesel". In the 2017 annual report (page 151), these same sources are specified as being non-renewable.

"the remaining 67% is formed from indirect sources such as electrical energy and steam purchased. Of the total electrical energy used by the Group, more than 38% derives from renewable sources"

The graph on page 107 shows the exact percentage of electricity to be 41%.

0.41 * 0.38 = 15.58% of the total energy that is renewable. The remaining 84.42% is therefore non-renewable.

Total energy consumption in GJ for 2016 = 13,415,824 (page 106).

13415824 * 0.8442 = 11,325,638.62 GJ
