The prospect of power cuts in the UK is becoming increasingly real as the forecasts for spare electricity capacity in the UK are getting ever more dire. So how should we act to address this – do we switch off, switch equipment or even switch energy sources? This talk will explore why electricity is under such pressure, and what tools we in the UK – both as individuals and collectively – have at our disposal to address the gap.
Chris Goodall is a Guardian columnist, author of Ten Technologies to Save the Planet and blogger at www.carboncommentary.com.
------------
Switch Off Week is a chance for all University of Cambridge members to switch off lights, computers, and office and laboratory equipment, making the University greener and reducing our £16 million energy bill.
