The UCL-Energy was established as UCL's response to the global challenges of mitigating climate change and providing energy security in the 21st century. Our multi-disciplinary research programme and strong industry links provide excellent foundation for PhD study. Our graduates are employed by the world's foremost academic, industry and governmental institutions. The UCL Energy Institute brings together different perspectives, understandings and procedures in energy research, transcending the boundaries between academic disciplines. We are the UK's leading academic group in the critical research areas of energy demand and energy systems. As these topics span science, engineering, economics and the social sciences, our research methodologies, models and data are explicitly multi-disciplinary. A PhD indicates a highly qualified researcher, capable of independent analytic thought. It is a highly regarded qualification for those wishing to attain senior management positions in industry, consultancies and public sector organisations, and is essential for those interested in pursuing careers in academia.
