What uses the most energy at school?
The Highest Energy Consumption Appliances in Schools Schools are a prime example of the benefits of energy efficiency. They are among the country’s largest energy consumers, and as such, they need to make every effort to keep costs down. Members of your school’s governing body who are in charge of finding ways to may consider an energy audit as a first step.
- The second step is to ensure that you are implementing all the changes you can make, such as installing LED lights or turning off lights when they are not needed.
- The third step is to look for opportunities for partnerships with others who can help you with your efforts, like local businesses or utilities.
The most energy-consuming appliances in schools are the heating, ventilation, and air conditioning systems. This is because they are constantly running to regulate the temperature in the building. Follow along as we delve deeper into some of the highest energy-consuming appliances and what steps can be taken to save on energy usage. HVAC systems and aircon are the largest consumers of energy in educational facilities. Additional measures can be taken to help control energy usage. We’ve included some ideas in this regard: The heating system has the highest consumption in schools. It is used every day during the colder months.
- It is necessary to keep students and teachers warm during the winter.
- The heating system can be controlled by the temperature in the room.
- With the summer months approaching and heat waves on the horizon, schools are looking for ways to stay cool.
- One way to do so is by installing ventilation systems with a high-efficiency rating.
These units provide fresh air while reducing energy usage and improving indoor air quality. The summers are getting hotter, and schools are doing their best to keep students cool. But have you ever noticed that your school’s AC is always high? This can cost your district a lot of money! There are a few simple ways to reduce your electricity bill when using your air conditioner! Improper use of air conditioners will actually increase power consumption.
If not needed, do not set the air conditioner to 16 degrees because it uses more power and may make you uncomfortable. Set the air conditioner around 23–25 degrees for optimal cooling and energy savings! Air conditioner filters matter. If it is not cleaned for an extended period, it will emit odours. Still, it will also consume more power, which is why it is usually recommended to clean the filter once a week, especially for high-usage air conditioner users.
If you regularly turn on and off your air conditioner, your electricity bill will suffer. Switching frequently uses more power. Even if you are leaving the room for a short time, leave the air conditioner on if you’re returning later. Inverter save more energy than regular air conditioners (non-inverters).
To save power, an inverter air conditioner’s compressor works at a constant speed after attaining the predetermined room temperature. We suggest switching to an inverter air conditioner that features four powerful motors. Additional steps to reduce the cost of these high-energy consumption appliances include calculating the cost of energy usage at school.
To calculate the energy costs for a school in the UK, you first have to find out what the school’s annual electricity consumption is. The easiest way to find this information would be by looking at the school’s profit and loss statement. From there, you can calculate how much it would cost to run their lights and appliances for a year.
- It will save the school money in the long run.
- Because of the environment-friendly benefits.
- It offers numerous health benefits.
Finally, it would be wise to find alternative ways to deal with energy-intensive appliances in schools. You may want to consider the following:
- What are the problems with these appliances?
- How can we reduce their impact on the environment?
- What solutions can you implement at your school?

What energy class is most efficient?
Reduce energy consumption Manage your electric appliances Lower your energy bills
When you’re buying a new appliance for your home, look out for its energy label. The energy label tells you how much energy that appliance uses, comparing it to similar appliances. This can help you find appliances that use the least amount of energy. You should also consider the size of the appliance you need.
- Appliances are tested for how much energy they use during typical use.
- This gives them a rating on a scale of A to G, with A being the most efficient product of its class, and G being the least efficient.
- Some appliances use an older scale, from A+++ to G, with A+++ being the most efficient.
- In general, appliances are categorised by their size.
This means that two different sized appliances with the same energy rating might use different amounts of electricity. For instance, a G-rated 265-litre fridge freezer could cost around £100 a year to run (60kgCO2e), whereas a larger 424-litre fridge freezer with a better F rating could cost around £105 (65kgCO2e) a year to run.
It’s best to check the appliance’s energy label, and look for the product with the best energy rating for the size you require.If you live in England, Scotland or Wales, you can find more information about the energy labels on the Label 2020 website.
If you live in Northern Ireland, more information on the energy label is available on the,
The average UK household spends £65 a year powering appliances left on standby (40kgCO2e). Standby is the energy used by certain appliances when not in use and not switched off at the plug. As well as standby power, other new additions to the average household’s collection of electrical goods, such as broadband modems, broadband routers, smart speakers, digi-boxes and telephones, use low levels of electricity when not in use.
We tend not to think to switch these off, but as they’re often on for 24 hours a day, these appliances gradually consume a great deal of electricity. Fortunately there are a number of products available to help cut down your standby electricity consumption, such as standby savers that allow you to turn all your appliances off standby in one go.
Some come with timers and others come with a single off-switch. EU regulations specify that non-networked electrical devices sold after 2013 cannot have a standby power greater than 0.5W, and networked-connected devices (for example, televisions or games consoles connected to the internet) must not consume more than 3-12W, depending on the product. Find out more about common appliances for the home and key considerations for each appliance type.
The highest rated gas and electric ovens are A+++. A pyrolytic function can also be an energy intensive means of cleaning, which can contribute to higher running costs. The energy label is now found on both electric and gas ovens, enabling you to make the most efficient choice for either fuel. Microwaves often provide a much more energy efficient way of cooking food than in the oven. Unlike ovens, microwaves only heat your food and not the air-space inside. Almost 8% of our electricity bill is spent running the dishwasher, typically costing between £50 to £100 (30 to 60kgCO2e) a year to run a standard sized dishwasher. However, slimline dishwashers typically cost between £40 to £75 (25 to 45kgCO2e) a year to run. These are switched on 24 hours a day, seven days a week, and are some of the longest lasting appliances in our homes, so it’s worth finding energy efficient models. Energy label scales range from A to G, and choosing a higher rated fridge freezer can have a significant impact on your running costs.
Choosing a A-rated fridge freezer over a F-rated unit will save you about £800 (670kgCO2e) in energy bills over the 17-year lifetime of the product. However, as the energy rating is categorised by size, choosing a smaller fridge will use less energy than a larger fridge with the same energy rating, and may even use less than a higher rated one.
You can compare the total energy consumption of appliances by looking for their yearly energy consumption in kWh/annum – it’s displayed under the rating scale on the energy label. Kettles are one of the most used appliances in the kitchen. A found nearly three quarters of us admit that we at least occasionally boil the kettle with more water than we’re going to use. Buying an ECO kettle that only boils the amount of water required can use 20% less energy than a conventional electric kettle, or just avoid overfilling and save yourself £13 a year on your electricity bill (8kgCO2e). Drying clothes outdoors on a washing line costs nothing and uses no energy, so it is the ideal way to dry your clothes. Indoors on a rack can also be a no-cost, no-energy solution, although you should be mindful of the increase in moisture levels. Keep the room ventilated so that that moisture doesn’t turn into damp.
Tumble dryers use an energy label scale of A+++ to D. Choosing an A+++ rated one over a B-rated could save you around £980 (770kgCO2e) over its 13-year lifetime. Some have sensors that tell you when your clothes are dry enough, preventing you from wasting energy by over drying your laundry. Electric heat pump tumble dryers are more efficient as they recycle the heat from the ventilation tube back into the dryer after removing the water vapour from the air.
There are also gas tumble dryers. This type of dryer can be slightly more expensive to install, as it needs a gas connection. An energy efficient washing machine will save you money on your electricity bill and, if you have a meter, your water bill too. Washing machines use an energy label scale of A to G. Choosing an A-rated washing machine over a D-rated one could save you around £130 (100kgCO2e) over its 11-year lifetime. Laptops typically use 65% less electricity over a year than desktop PCs. Choosing a laptop over a desktop and avoiding leaving the laptop in standby could save up to £45 per year (25kgCO2e). Tablets have even lower energy usage – on average, tablets use 70% less power than laptops.
Smart speakers generally cost around £8 per year (5kgCO2e) to run, with most of that cost from running them on standby. It’s worth considering whether you do need them on 24 hours a day. Digital radios are a popular electronic product. Similar to smart speakers, consider switching them off when you leave the room instead of leaving them on standby.
Televisions can be the most power-hungry of all entertainment equipment, particularly the largest ones. The larger a television screen, the more energy it will consume, regardless of its energy rating. The following table includes examples of annual running costs depending on the size of your TV, as well as the CO2 equivalent saving:
|Running costs per year
In our cost comparison table, even the most efficient 60″ television is still more expensive to run per year against the lowest rated 32″ television. By choosing a smaller television, you are generally saving more energy. LED screens are the most common form of flat-screen TV on the market. LED TVs use an LCD (liquid crystal display) and LEDs provide the backlighting to create the picture. OLED and QLEDs are similar to LED screens in that they both use an LCD display. The difference with OLED and QLED is that you don’t require backlighting, each pixel lights itself. Both types boast very high performance in picture quality; however, currently these do come at a premium. Power consumption is mostly dependent on level of brightness and hours of use. After selecting the smallest TV still suitable, the best ways to save energy are to reduce brightness settings to your lowest acceptable limit and remember to switch off your TV when not in use. Many TVs incorporate features to do this automatically, such as light sensors to detect the room’s brightness and adjust the screen accordingly, and sleep timers to switch off the TV after a number of hours of no interaction. Plasma TV production ended in 2015. And since 2014, lamp lit LCDs (as opposed to LED lit) are in very limited production. Both of these TVs use more power than the LEDs discussed above.
Electrical items should be disposed of carefully due to the nature of their materials. Items that have the image of a wheelie bin with a cross on them should not be disposed of using the general household rubbish collection. These items include everything from large white goods to energy saving lightbulbs.

Why is it so hard to save energy?
Why Is It So Hard To Save Electricity? Home appliances are more efficient than ever. LED light bulbs use a fraction of the wattage used by incandescent light bulbs. Related: Phantom power consumption for the standby mode of consumer electronics like televisions has never been lower.
- So with all of these new energy efficient advancements, each of which has widespread adoption in U.S.
- Households, why aren’t your home’s electric utility bills lower? The simple answer is that your home has more devices today than it has ever had before, and this multitude of electronics adds up to increased power needs that more than offset the savings being generated by more efficient appliances and “no-load” electric device requirements.
Plus, utility rates have increased. According to the U.S. Department of Energy, in 2009, the average American household paid $99.70 per month for electricity, using an average of 936 kWh per month. Today (in 2016 actually), the typical U.S. household paid $112 per month for electricity.
- This equates to an average used of 897KWh per month.
- So power usage has actually fallen in the past seven years, but electric utility pricing has risen, which is part of the reason your bill is higher.
- But just as important is the growth in the sheer number of devices in the home.
- Shows that two-thirds of all American households own a tablet and a smartphone.
And 36 percent of households own a smartphone, laptop or desktop computer, and a tablet. All of these require a connection to the Internet, and which requires a router. So let’s do some quick math for all those devices you have plugged in:
Wireless routers uses nearly 53 kWh per year = $6/year Desktop computer uses 260kWh = $30/year Apple TV (first generation) uses 148 kWh (when the device is off) = $17/year DVR uses 11 kWh (when off) = $26/year
And these devices are just the tip of the iceberg when you consider smartphones, EV charging stations for vehicles, printers, etc. But you better get used to it the International Energy Agency.
