William S Hart Union High School District is a public school district located in Santa Clarita, California, United States. The district serves approximately 22,000 students in grades 7-12 across 16 schools. The district is committed to providing a high-quality education to its students while also being environmentally responsible. As such, the district has taken several steps towards decarbonisation and renewable energy.

One of the ways in which the district is working towards decarbonisation is through its corporate energy program. The district has implemented several energy-saving measures, such as installing LED lighting, upgrading HVAC systems, and implementing energy-efficient building designs. These measures have helped the district reduce its energy consumption and carbon footprint.

In addition to energy-saving measures, the district has also invested in renewable energy. The district has installed solar panels on several of its schools, which generate clean energy and reduce the district's dependence on fossil fuels. The district's solar panels have a combined capacity of 3.2 megawatts, which is enough to power approximately 600 homes.

To further its commitment to renewable energy, the district has also entered into a corporate power purchase agreement (PPA). The PPA allows the district to purchase renewable energy from a local wind farm at a fixed price for a set period of time. By entering into the PPA, the district is able to support the development of renewable energy while also reducing its carbon footprint.

The district's commitment to renewable energy and decarbonisation has not gone unnoticed. In 2019, the district was recognized by the California Energy Commission as a Green Ribbon School District. The award recognizes schools and districts that are taking steps towards sustainability and environmental stewardship.

In addition to its commitment to renewable energy, the district is also working towards reducing its overall environmental impact. The district has implemented a recycling program at all of its schools, which has helped divert waste from landfills. The district also encourages students to reduce their environmental impact by promoting sustainable practices, such as using reusable water bottles and reducing paper waste.

The district's commitment to sustainability and environmental stewardship is not only good for the environment, but it also has financial benefits. By implementing energy-saving measures and investing in renewable energy, the district has been able to reduce its energy costs. The district has also been able to generate revenue through its PPA, which helps support its educational programs.

Overall, the William S Hart Union High School District is a leader in sustainability and environmental stewardship. The district's commitment to decarbonisation, renewable energy, and corporate energy has helped reduce its carbon footprint and promote sustainability. The district's efforts have not only benefited the environment, but they have also had financial benefits, which help support the district's educational programs. The district's commitment to sustainability serves as a model for other school districts and organizations to follow.
