What You'll Learn
Turn off devices and lights when not in use
Reducing electricity consumption in schools can be achieved through simple measures such as turning off devices and lights when not in use. This can lead to significant cost savings and a reduced carbon footprint for the school.
Lights
Turning off lights in empty rooms is a simple yet effective way to reduce electricity consumption. Schools should encourage staff and students to switch off lights when leaving a room. This is especially important for incandescent lights, which are the least efficient type of lighting, with 90% of their energy emitted as heat and only 10% resulting in light. Halogen lights, while more efficient, are still less efficient than CFL and LED lights and should also be turned off when not needed.
LED lights are a more efficient and cost-effective alternative to traditional bulbs, using up to 85% less energy and lasting much longer. Upgrading to LED lighting can cut costs by reducing electricity consumption and lowering maintenance expenses.
Devices
Schools should ensure that computers, laptops, printers, and other electronic devices are turned off at the end of the day. ICT and audio-visual equipment are major energy consumers, so powering them down can significantly reduce electricity usage. Computers should be set to sleep mode with displays turned off after a few minutes of inactivity.
Power Strips and Timers
Using power strips with individual switches can make it easier to cut off standby power from unused devices. This is especially useful for larger equipment such as copiers, water coolers, and vending machines. Plug-in timers can also be used to automatically switch devices on and off at preset times, providing an efficient way to manage energy consumption.
Natural Light
Maximizing natural light in classrooms can reduce the need for artificial lighting. Studies have shown that students are more productive when working in natural daylight. Teachers can be encouraged to open blinds and utilize natural light, reducing the reliance on electric lighting.
By implementing these measures, schools can significantly reduce their electricity consumption, lower their environmental impact, and free up resources for other important areas.

Use smart power strips
With hundreds of different electrical devices in schools, it can be challenging to ensure that every single piece of equipment is switched off. A smart power strip can be an effective solution to this problem.
A smart power strip helps cut off power from specific sockets when the device is switched off. This is especially useful for large equipment such as copiers, water coolers, laptop chargers, and vending machines. This way, the standby power of unused appliances can be cut off without worrying about accidentally turning off essential devices like refrigerators.
Smart power strips are also useful when it comes to unplugging all power sources before weekends and holidays. Electronic devices can still consume 5-10% of their normal energy consumption when turned off, and equipment in standby mode will heat up the space, causing more air conditioning energy use.
Additionally, smart power strips with individual switches for each socket can be used to make it easier to unplug devices. This can be implemented in rooms with the most equipment, such as staff rooms and computer labs.
By using smart power strips, schools can save energy on a day-to-day basis and make it more convenient to unplug devices during holiday breaks.

Upgrade lighting
Upgrading lighting systems can be an expensive initial investment, but there are many incentives to offset or entirely cover the cost of lighting projects. The benefits of upgrading lighting include significant long-term savings on electricity bills, with upgraded lights potentially using only 20-25% of the energy of traditional lights, and lasting 15-25 times longer.
LED lights are currently the most efficient lighting option available, and they are only getting more efficient and cheaper to produce over time. Upgrading to LED lights from fluorescent and CFL lighting will cut costs in two ways: LED lights use much less electricity and produce very little heat, helping to reduce the energy required for air conditioning. Secondly, LED lights last much longer and don't require a ballast, saving money on maintenance.
Another way to reduce electricity consumption through lighting is to take advantage of natural light. Studies have shown that pupils are more productive when working in natural daylight, so encouraging teachers to open their blinds and utilise natural light before turning on electric lights can improve productivity and reduce electricity costs. Schools being remodelled or built can include ways to maximise natural light, such as by adding skylights to common areas like hallways and bathrooms, and using blinds and other window fixtures to minimise glare.
To further reduce lighting costs, timers and lighting controls can be used to automatically turn off lights in rooms that are not in use. Schools can also encourage staff and pupils to manually turn off lights when they leave a room, which could cut lighting costs by up to 15%.

Install solar panels
Installing solar panels is a great way for schools to save money and energy. In 2019, an estimated 4 million students in the U.S. attended a school that used some form of solar power application. This number is expected to increase as solar panel efficiencies improve and manufacturing costs decline.
There are several factors to consider when installing solar panels at a school. Firstly, it is important to engage with the school's facilities manager and a solar company with relevant school experience. They can provide insights into the operational and logistical aspects of installing the panels. It is also crucial to understand the school's energy landscape, including its electricity consumption patterns, utility costs, and future energy requirements. This information will help determine the size and scope of the solar panel project.
Another important consideration is space availability. Schools will need adequate roof space or open land for solar panels. Roof-mounted systems are the most common, but if the roof is not suitable, ground-mounted systems can be a viable alternative. Local zoning laws and building codes may also dictate where solar panels can be installed.
The cost of installing solar panels can vary depending on the state, system size, and incentive programs. Schools have the option of direct ownership, where they pay for and maintain the system themselves, or third-party ownership, where a company installs and owns the system, and the school purchases the electricity at an agreed-upon rate. This option can help schools go solar with little to no upfront cost.
Solar energy offers a great return on investment. Schools typically recoup their initial investment within 5 to 10 years and then benefit from free energy for the remaining 20+ years of the system's lifespan. In addition to the financial benefits, solar energy can also help schools meet their sustainability goals and provide educational opportunities for students.

Use sensors and timers for lights
Schools can use sensors and timers to reduce electricity consumption from lighting. Lighting accounts for a significant portion of a school's energy use, and leaving lights on unnecessarily can increase costs.
Timers can be set to switch lights on and off at specific times, ensuring they are only on when needed. There are both manual and programmable digital timers. Manual timers plug into electrical outlets to control lamps or light strings, while programmable timers can be set to automate indoor or outdoor lighting. However, programmable timers may need to be reset frequently due to seasonal variations in daylight duration. Combining timers with other controls, such as photosensors, can be an effective solution. For example, a photosensor can turn lights on at dusk, and a timer can turn them off at a set time, such as 11 p.m.
Sensors, such as motion sensors, can also be used to automate lighting. Motion sensors detect movement and turn lights on or off accordingly, ensuring lights are only on when someone is present in the room. Infrared sensors, for instance, detect heat and motion, making them useful for task lighting in areas like kitchens. Photosensors, or light-sensitive controls, can prevent lights from operating during the day by detecting ambient light levels. These are particularly useful for outdoor lighting, where lighting needs are more consistent and less dependent on occupant activity.
Using timers and sensors to control lighting can help schools reduce energy consumption and lower electricity costs. These measures can also reduce the time and effort required to manually switch lights on and off, providing a more efficient energy management solution.
