Technology adoption data

Adoption data for the technologies investigated is taken from a wide variety of sources due to the broad scope of the technology domains considered. Where possible, global technology sales and shipment values have been used to determine the overall market share of each technology at a given time, although in some cases data values have been imputed to fill gaps in time series (this is stated where this has been applied, as well as the method of deriving imputed values). Furthermore, the preference has been to extract statistical data directly from international agencies such as the UN, World Bank, International Energy Agency, International Council on Clean Transportation, International Telecommunication Union, and Eurostat when available, as these organisations generally present the most consistent representation of the technologies considered when taking into consideration regional development trends. In many cases, this information was accessed via the UK Data Service (Service 2017).
A brief description of each data source used for technology adoption data is given in Table 5:
