Visitors to this year’s Times Cheltenham Science Festival enjoyed two events from the Royal Academy of Engineering on energy: an Oxford debate on wind power and a platform discussion on the challenge of heating our homes in a low carbon era.
In the debate, science broadcaster Vivienne Parry, in the chair, put the motion to the panel members and the audience: “This House believes that Britain should be a fan of wind energy”.
Speaking for the motion were Dr Andrew Garrad FREng and environmentalist Jonathon Porritt, who proposed that wind would play a key role in future energy production alongside other renewable sources. Taking the stand against the motion were energy policy analyst John Constable and writer and independent political researcher Ben Pile.
In a heated debate, concerns were raised as to the cost and efficiency of wind power, along with the consequent need to redesign the grid in order to manage this intermittent form of energy. Audience members also questioned whether wind really did represent a form of energy security for the UK – as the manufacturing of turbine magnets required the rare earth neodymium from China. However these concerns were rebutted by Dr Garrad who explained that turbines did not necessarily need rare earth magnets, raising the point that a wind turbine could function for 20 years, and make up for the carbon costs used for manufacture in just nine months.
In the platform event, Professor Roger Kemp FREng took to the stage with television presenter Robert Llewellyn to discuss the challenges of heating our homes in an energy efficient way. Professor Kemp outlined the key points from a recent Academy study on domestic heating, which he had led. As most of the houses that will exist in 2050 have already been built, Professor Kemp explained that major improvements will have to be retrofitted to existing homes. However, given the diversity of the buildings involved, not one solution will work for all. He also highlighted the need for a skilled workforce who are able to work with and understand new technologies such as heat pumps.
