Iain Staffell is a multi-disciplinary scientist holding degrees in Physics, Chemical Engineering and Economics.  He is a Senior Lecturer in Sustainable Energy at the Centre for Environmental Policy with fifteen years’ experience in energy R&D. 

Iain is co-developer of the, an open web platform that lets you simulate the hourly power output from wind and solar power plants located anywhere in the world.  Iain also leads the Electric Insights project, an interactive website and quarterly report on the supply, demand, price and environmental impacts of Britain's electricity.  He is one of the founders of Power Swarm, a network of 400 academics, industry and government experts working on power system transformation

Iain's research centres on decarbonising electricity systems, ranging from the economics of battery storage and productivity of offshore wind farms to efficient ways of integrating renewables into electricity markets.  Broad research areas include the potential of an interconnected super-grid and smart energy storage systems to reduce the cost and carbon emissions of generating electricity across Europe; the impacts that climate change will have on the business case for renewables; the role of flexible fossil power in balancing decarbonised energy systems; and residential-scale microgeneration for decarbonising the heat sector.

As energy, renewables and carbon are never far from the public eye, Iain's resarch and commentary have appeared in the BBC (2), The New York Times, Time MagazineDer SpiegelThe FT (2) (3), Forbes (2)The Times (2) (3), The Telegraph (2)The Guardian (2) (3), CNNThe Sun, Huffington Post, The Conversation, Bloomberg (2), Quartz (2), Vice, Die Zeit and Esquire.

Iain holds a visiting position at the Swiss Federal Institute of Technology - ETH Zürich, within the Climate Policy Group.


Iain co-convenes the Energy Policy option of the Environmental Technology MSc course, lecturing on energy systems, economics and policy.  He also teaches for Imperial College Business School on the MSc in Economics & Strategy for Business and Climate Change, Management & Finance, and for the Energy Futures Lab on the MSc in Sustainable Energy Futures.
