TU Delft will convert to wind energy in January 2017. This should meet 70 per cent of the total energy needs on campus and reduce CO2emissions by 60 per cent. TU Delft indicated in a press release that when putting its energy supply out to tender it decided to ‘purchase 100% wind energy’. Each year TU Delft consumes around 54 million kWh, equal to some 15,000 households. In addition to wind energy, the university will continue to use its own combined heat and power plant and energy from the solar panels on its buildings.
