I made a Python script of a model which can be used to predict the market share of a product. See article here.
The model is from an article in the Nederlands Tijdschrift voor Natuurkunde (Dutch Journal of Physics) titled Waarom wij wel zonnepanelen maar nog geen kernfusiestroom hebben (Why we have solar panels but no nuclear fusion power) by Niek Lopes Cardozo, Guido Lange and Gert Jan Kramer (NTvN 83, October 2017, page 350-354). This article is again based on two previous articles by the authors. The one which is not behind a paywall, is called ‘The cradle of new energy technologies. Why we have solar cells but not yet nuclear fusion?’, published on December 2015 in ‘The colours of energy. Essays on the future of energy and society’. I then used it to predict the market share of electric vehicles with time, for the entire world (html, Jupyter Notebook) and Norway (html, Jupyter Notebook) specifically.
