How Schools Use Energy and How to Reduce Consumption

With computers, smartboards, and personal devices constantly in use, it’s no surprise that schools across the U.S. consume a significant amount of electricity. According to the Energy Information Administration (EIA), educational buildings accounted for 13% of the electricity used in commercial buildings in 2018.

Understanding how schools use energy is the first step toward reducing consumption and making educational institutions more sustainable. The most energy-intensive aspects of schools include space heating, cooling, lighting, and ventilation. With nearly 100,000 public schools nationwide, the education sector remains a major contributor to electricity usage. However, with smart strategies and behavioral changes, schools can significantly cut down on energy waste while saving money on utility bills.

The Importance of Energy Conservation in Schools

Reducing energy consumption in schools benefits both the environment and school budgets. Lower energy use decreases greenhouse gas emissions, lessens the strain on the power grid, and helps fight climate change. Additionally, funds saved on energy costs can be redirected toward educational resources, improving student learning experiences.

One of the most effective ways to lower energy use is by involving students, teachers, and administrators in conservation efforts. By incorporating energy-saving techniques into daily routines and lesson plans, schools can develop a culture of sustainability that extends beyond the classroom. Here are some practical and impactful ways to save energy in schools.

7 Effective Energy-Saving Strategies for Schools

1. Turn Off and Unplug Personal Devices

From smartphones to laptops, students and teachers use electronic devices throughout the school day. Although individual devices may not use much electricity on their own, their collective energy consumption adds up. Encouraging students to activate power-saving mode and delay charging their devices until they get home can make a difference.

Additionally, devices such as projectors, TVs, and smartboards continue to draw power even when turned off. This “phantom energy” consumption can be minimized by unplugging electronics when they’re not in use. Schools can also install smart power strips that automatically cut power to unused devices.

2. Turn Off Lights in Empty Rooms

Switching off lights when leaving a classroom is an easy yet often overlooked habit. Students and teachers should be reminded to turn off lights in unoccupied spaces, such as classrooms, bathrooms, and staff rooms. Setting up reminder signs near light switches can reinforce this behavior.

To further cut energy waste, schools can switch to LED lighting, which uses up to 90% less energy than traditional incandescent bulbs and lasts significantly longer. Additionally, installing motion-sensor lights in hallways and restrooms can ensure that lights are only on when needed.

3. Optimize Heating and Cooling

Heating and cooling systems are among the largest energy consumers in schools. Simple measures can help reduce unnecessary energy use:

• Keep classroom and exterior doors closed to maintain stable indoor temperatures.
• Adjust thermostats to energy-efficient settings (68°F in winter and 78°F in summer).
• Ensure HVAC systems receive regular maintenance for maximum efficiency.
• Use ceiling fans to circulate air, reducing the need for excessive heating or cooling.

Encouraging students and staff to dress appropriately for the weather can also help lessen reliance on heating and cooling systems.

4. Use Power Strips and Timers

For devices that need to remain plugged in, power strips with timers or smart outlets can help reduce wasted energy. These tools can be programmed to automatically shut off electronics at night or when classrooms are empty. This simple investment can lead to significant energy savings over time.

5. Increase Natural Light Usage

Maximizing natural daylight not only reduces energy consumption but also creates a healthier learning environment. Studies show that students exposed to natural light perform better academically and experience improved focus.

• Open blinds and curtains to allow more sunlight into classrooms.
• Rearrange desks to make the most of available daylight.
• Consider installing skylights or light shelves to enhance natural lighting.

6. Invest in Renewable Energy Sources

Many schools are turning to renewable energy sources, such as solar panels, to lower their carbon footprint. School rooftops provide ample space for solar panel installations, which can significantly cut electricity costs and even generate excess energy that can be fed back into the grid. Schools interested in solar energy can explore state and federal incentives to help offset installation costs.

Additionally, some districts participate in energy buyback programs, where schools receive credits for the renewable energy they generate.

7. Educate and Empower Students

One of the most effective ways to instill long-term energy-saving habits is by incorporating sustainability into the curriculum. Schools can:

• Integrate lessons on renewable energy, climate change, and conservation.
• Create energy-monitoring programs where students track electricity use in their classrooms.
• Organize “green teams” where students lead initiatives to reduce waste and improve sustainability.
• Encourage competitions between classrooms to see who can reduce the most energy usage over a set period.

When students feel involved and responsible for their school’s energy conservation efforts, they are more likely to adopt sustainable habits that extend beyond the classroom.

Conclusion: Small Changes, Big Impact

Reducing energy consumption in schools is not just about saving money—it’s about fostering a culture of environmental responsibility that benefits future generations. By implementing simple yet effective energy-saving strategies, schools can lower their carbon footprint, cut down on costs, and create healthier learning environments for students.

Whether through small behavioral changes, technological upgrades, or investing in renewable energy, every step toward sustainability counts. Encourage students, teachers, and administrators to work together in making energy conservation a priority—because every watt saved contributes to a brighter, greener future.
