Ka Hei overview: Capturing energy, absorbing knowledge
Ka Hei, a specific type of snare made with ropes, is what the Hawaiian god Maui used to capture the sun in the Hawaiian tradition. Ka Hei also means “to absorb as knowledge or skill.” Coupled with revamped facility upgrades, an important component of Ka Hei is the suite of educational opportunities that will help engage students and staff in energy awareness and STEM education.

Hawaiian Language Immersion Program educational specialists selected the name for this ambitious program. Ka Hei conveys our opportunity to not only harness the power of the sun to power our schools, but our goal to empower our students and teachers to adapt new ideas about sustainability for the benefit of our greater community.
The Department spends more than $62 million a year on electricity, gas, water and sewage fees — a 50 percent increase over the past 10 years. We are excited to improve our sustainability profile by lowering energy expenses, protecting the environment and reinvesting funds into the classroom.
Through a combination of energy efficiency measures, clean energy generation (including the Department's ongoing
photovoltaic project, small-scale wind turbines, and other viable systems) and a comprehensive sustainability program, Ka Hei will improve the learning environment so students and teachers can perform at their best. The Department is partnering with OpTerra Energy Services to ensure success of this multi-year program.
This program will enhance the Department’s and individual schools’ existing initiatives to create an interactive learning platform that brings the worlds of STEM (science, technology, engineering, and math) and sustainability to life. Ka Hei will leverage technology to bring real-world relevance to the learning experience that not only meets
Hawaii Common Core standards, but can be implemented alongside existing lesson plans.
Students and teachers will experience science lessons through on-campus Living Laboratories and curricula that are hands-on, island-based, and relevant for college and career preparedness. From opportunities to shadow engineers and subject matter experts in the field, to analyzing energy data from a live feed on site, students and teachers will have greater access to the tools and ideas needed to build a more diverse, sustainable energy future for Hawaii.
As part of Ka Hei, teachers will receive ongoing professional development sessions from several community partners. These workshops and their supplementary materials are designed to integrate the energy technologies being installed to modernize campuses and complement classroom learning.
- Reduce the cost and consumption of energy at all 256 DOE schools.
- Build a diverse portfolio of new, clean, on-site generation.
- Aggressively implement energy efficiency and conservation measures including demand response.
- Support the goals of the Hawaii Clean Energy Initiative to achieve 100 percent clean energy use in the state by 2045, and Board of Education Policy 6710: Sustainability.
- Leverage these transformational activities to create educational opportunities and stimulate the economy through local construction labor.
- More than $24 million in estimated savings in operating expenses over five years.
- 100 megawatts of on-site renewable energy generation potential.
- 25 percent reduction in energy consumption over five years.
- 30 percent reduction in water consumption over five years.
- Creation of standardized and controlled classroom environmental conditions.
- Integration of project-based curriculum focused on STEM and sustainability in every school.
- Creation of student career pathways in the energy and sustainability field.
- Long-term economic development through direct and indirect local job creation.
