Correction of REDII translations

The error was found in the crucial 8th paragraph of the article. In the English version the paragraph states that electricity suppliers shall demonstrate the share or quantity of energy from renewable sources by using Guarantees of Origin. In the French translation this requirement had been weakened to state that electricity suppliers may demonstrate the share or quantity of energy from renewable sources by using Guarantees of Origin. A similar problem was found in the Bulgarian translation of this paragraph. After alerting the European Commission it was agreed that the error will be corrected shortly.
