The video discusses a large photovoltaic array that generates 2.6 gigawatts of energy annually, enough to power 850 homes. Installed in 2014, the array was developed in partnership with an investment company, providing ongoing benefits. Over the past five years, more than 54 energy-saving projects have been implemented, saving over 62 gigawatt-hours of energy, sufficient to power 4000 UK homes. These efforts significantly reduce the carbon footprint of the Oxford facility.
