Sustainable Power is one of the research themes under which Energy Futures Lab organises its activity and the energy research being done at the College.
Low carbon energy has already grown to significant fraction of electricity generation in many nations but the imperative remains to improve performance and drive down cost.
As a world leading institution in the field Imperial has a rich portfolio of basic and applied research in a wide range technolgies giving us a diverse portfolio relevant to all regions of the world.
