The PhD degree in Sustainable Energy Engineering at Busitema University is awarded after successful completion of a Research (and Development) project in a specific niche energy engineering area, lasting not less than three years of registration. The actual length of the project may vary depending on the rate of progress and time allocated to the work by the particular candidate. In general, however, this time should not exceed 6 years, as work done or assumptions made earlier in the research may easily be superseded by developments elsewhere in that time
