The Energy Delta Institute, a provider of courses on many subjects related to natural gas, wants to know the market potential of the different national natural gas markets and market players in three European regions. This research uses data about thirty-nine national natural gas markets to make a ranking of countries based on their overall market potential for EDI. It will specify the degree of priority that EDI’s marketing department should give to each country and will indicate the differences in market potential in the different European regions. Also, 171 companies from the countries with the highest market potential for EDI are ranked based on company characteristics found to be important in influencing training and development activities in earlier research. The results of this research can be used by EDI’s marketing department in setting priorities and deciding which markets to enter and which companies to approach.
