   Sammanfattning : If the European Union is to become climate-neutral by Year 2050, as envisioned in the European Green Deal, the European energy system must undergo an unprecedented transformation towards eliminating its carbon emissions. For this transition, renewable electricity plays a central role, not only in replacing the current fossil-based electricity generation, but also in promoting the electrification of other sectors, such as transport and industry, sectors which are currently based on fossil fuels.

   Sammanfattning : This corpus-based variationist study traces the history of the English number word MILLION from its first attested use in the 14th century, focusing on the diachronic shift in function from one of heading its noun phrase (NP), as in the obsolescent (Obs) construction three millions of citizens, to one of a post-determiner of its NP head, as in Present-day English (PdE) three million citizens. The authentic historical materials used include both numerous electronic linguistic corpora and, more innovatively, very-large-scale general collections available online, especially historical newspaper collections from the US and UK comprising tens of billions of words.
