Oklahoma State University (OSU) is a public research university located in Stillwater, Oklahoma. Founded in 1890, OSU is the flagship institution of the Oklahoma State University System, which includes five other campuses across the state. With an enrollment of over 24,000 students, OSU offers more than 200 undergraduate and graduate degree programs across its six colleges.

In recent years, OSU has made significant strides in decarbonisation and renewable energy. The university has committed to reducing its greenhouse gas emissions by 30% by 2030, and has implemented a number of initiatives to achieve this goal.

One of OSU's key strategies for decarbonisation is the use of renewable energy. The university has invested in a number of renewable energy projects, including a 10 MW solar farm and a wind turbine that generates 2.5 MW of energy. These projects have helped OSU to reduce its carbon footprint and to generate a significant portion of its energy from renewable sources.

In addition to investing in renewable energy, OSU has also implemented a number of energy efficiency measures to reduce its overall energy consumption. The university has upgraded its lighting systems, HVAC systems, and building envelopes to improve energy efficiency, and has implemented a number of behavioural change programs to encourage students, faculty, and staff to conserve energy.

OSU has also implemented a corporate power purchase agreement (PPA) to support its renewable energy goals. The university has signed a 20-year PPA with a wind farm in western Oklahoma, which will provide OSU with 50% of its electricity needs. This PPA not only supports the university's decarbonisation goals, but also provides a stable and predictable source of energy for the university.

In addition to its renewable energy initiatives, OSU has also implemented a number of corporate energy strategies to reduce its overall energy consumption. The university has implemented an energy management system to monitor and control its energy use, and has established an energy conservation program to encourage behavioural change among students, faculty, and staff.

OSU's commitment to decarbonisation and renewable energy has earned it recognition from a number of organisations. In 2020, the university was named a finalist in the Second Nature Climate Leadership Awards, which recognises institutions that are taking bold and effective action to address climate change. OSU was also named a Green Ribbon School by the US Department of Education in 2019, which recognises schools that are leading the way in sustainability and environmental education.

Overall, OSU's commitment to decarbonisation and renewable energy is a testament to its dedication to sustainability and environmental stewardship. The university's investment in renewable energy, energy efficiency, and corporate energy strategies has not only helped to reduce its carbon footprint, but has also provided a model for other institutions to follow. As OSU continues to lead the way in sustainability, it will undoubtedly inspire others to take action and make a positive impact on the environment.
