Leiden University opts for green energy

Since 2010 Leiden University has been running entirely on green energy. All our electricity is generated by hydropower. As a result, the university is making a significant contribution to the reduction of CO2 emissions.


Energy and water saving

In the past five years, Leiden University consumed on average approximately 580,000 Gigajoules of energy per year. Since 2010, we have witnessed a decrease in energy consumption of a few percent a year. In addition, since 2010, Leiden University has been purchasing green energy, which has reduced its average CO2 emissions by 75%.


Sustainable construction

A good building is half the work. A cleverly designed building greatly contributes to energy saving and is easy to adjust to changing work conditions. This can for instance prevent construction waste.
