GREEN ENERGY ‘HAT TRICK’ AT UNIVERSITY
E 40|
arlier this year (2010) the University installed 200 square metres of photovoltaic (solar) panels and nine 8.5 foot tall wind turbines on the top of the
South Tower at its Kedleston Road site, in Derby, to generate electricity. Together these two are capable of generating 28,787 kilowatt hours (kWh) of electrical power. A kilowatt hour is the amount of work that can be done by 1,000 watts of electrical power in one hour.
Now a third energy source – a 65 foot
tall ‘Quiet Revolution’ model wind turbine, just installed next to the Kedleston Road site’s main driveway – will mean the University could generate in total up to 31,827 kWh of its own power. This is enough to run 28 televisions or 78 laptops all day, every day, for a year. The University’s large wind turbine has vertical sweeping blades rather than being the traditional windmill shape, where blades are mounted on a horizontal axis. It’s estimated the combined might of

The latest ‘green energy’ project at the University of Derby means it could now generate enough free power to boil up to 31,000 kettles.
the three green projects could reduce the University’s carbon dioxide emissions – gases linked to global warming – by 18 tonnes per year. This would be enough to fill three and a half hot air balloons. The projects in turn are linked to the recently completed £13.5m refenestration and re-cladding of the three 1960s-built towers at the University’s Kedleston Road site, which has markedly improved their heat and energy efficiency.
Ian Willgoose, Director of Estates at the University of Derby, said: “As we update the University’s sites we are also trying to make them more sustainable. With this latest large wind turbine we can use wind and solar power to supplement our energy needs even more, meaning we need to buy less from electricity suppliers.” Anne Downes, University Energy
Officer, added: “Derby is receiving national
recognition for its efforts. In June (2010) the towers project won the
Sustainable Construction and
Refurbishment category at the 2010 Green Gown national
awards, which annually highlight those universities working to be more environmentally sustainable.
