It’s a light bulb moment

It’s a light bulb moment

This is how we describe the moment when we know our clients have realised that upgrading their lighting can actually be a great investment. For many businesses upgrading any equipment can have a cost barrier and we appreciate that lighting might be low on the priority list but that shouldn’t be the case.

Invest to save

Did you know that energy-efficient lighting can offer savings typically between 60-80% on energy costs? By upgrading your lighting to LED, it has a great return on investment which in most cases it is only a few years depending on what lighting you currently have. This means that you will be reaping the savings on your energy bills.

If you are concerned about not having the funds available, then there is good news. There doesn’t have to be an upfront cost as we can help you access funding which will keep your cash flow intact depending on your savings and due to the short ROI, it really stacks up financially too.

But the savings don’t end there as the new bulbs will last much longer (up to 50,000 hours which is the equivalent of being used 12 hours a day for 16 years) so you can also benefit from reduced maintenance costs. We uniquely offer a 5-year warranty and 1-year on-site support, so you don’t need to worry about additional costs for maintenance or replacement for some time.

Increase productivity

If the figures don’t give you enough of an incentive then how about the improved lighting increasing your productivity?

The right lighting can directly impact employee’s mood and productivity. Not only will it enable employees to see better to perform their job, we can select the right lighting colours to enhance specific areas in your business to aid concentration and wellbeing.

Fit for purpose

Investing in lighting that is fit for the environment and purpose is essential in any lighting upgrade as it will provide a much better use of light. When we create a lighting specification, we tailor the lighting in every area so that the lighting functions at its optimum.

For example, we can help create spaces with equal lighting regardless of the position of the window in the space which will offer the right visibility levels and comfort for employees.


We are confident that you will benefit from upgrading your lighting to LED from both the results and savings, this is why we offer a no-obligation, at no cost to you site survey. We will work with you to understand your lighting needs and budget so that we can create a tailored and personalised solution that will yield optimum energy savings.

We are very experienced installing lighting in a wide variety of environments, and we will work around your business to minimise any disruptions to your day-to-day business.

We only use products that we have tried and tested ourselves that are of high quality and the products that are fit for its purpose. We work closely with the manufacturers to get you the most competitive costs, and we also include a five-year warranty on all products.

Steps to a greener business

Steps to a greener business

So many businesses are looking for ways to reduce their long-term running costs as well as reducing environmental impact. As many of us are starting to become more aware of the environmental impact of their purchases, research has shown that a third of customers are choosing to buy from businesses that are actively and publicly reducing their impact on the environment.

If you are a business that is keen to become greener, as energy experts, we want to offer some great tips to get you started. Some can be much easier and more costs effective than you think.

  1. Reduce your energy consumption

On average buildings waste 40% of the energy they consume – now that’s a lot and think about how much that equates to on your energy bill. Ways to make savings are:

  • Switching to LED lighting is by far one of the most cost-effective energy-saving measures currently, with savings up to 80% and an attractive return on investment (ROI)! As LED lighting lasts so much longer (up to 50,000 hours), this means you will be saving on both maintenance costs as well as reducing on your waste.
  • Insulating walls and roofs to prevent heat loss and aid cooling in summer.
  • Implement turning off equipment when not in use (and at the end of the day) rather than leaving equipment on standby i.e. computers. Turning off computers overnight can save up to 75% of their energy costs! A photocopier left on overnight uses the same energy as printing 5,000 A4 sheets!
  • Service your heating appliances as those running ineffectively can cost up to 30% more to run.
  • Upgrade any old equipment that is energy-intensive to more energy-efficient products.
  1. Can you reduce, reuse, recycle to minimise waste?

Waste can be a costly expense for a business, both on the bottom line and disposal costs so it makes sense to reduce waste, reuse whatever you can and then recycle as much as possible. Sending waste to landfill is costly (currently just over £90 per tonne) and no doubt will become even more so in the future to encourage less wastage. Here are some ideas to reduce waste:

  • Check and see if you have enough recycling points and that they are accessible to encourage use.
  • Encourage your staff to recycle and create awareness by promoting what can be recycled.
  • Check if you have the right recycling contracts in place to recycle what you need to.
  • Create a paperless working environment – replace paper-based systems, digitise forms, reduce handouts in meetings and use projectors and laptops instead.
  • Try and use recycled paper products.
  • Set your printers to print double-sided to reduce paper wastage and purchasing costs.
  1. Be smarter

Technology can offer many means of support in reducing your energy, these include:

  • Having smart controls/technology for lighting and heating can reduce the need for human intervention. A good example of this is having motion sensors on your lighting, the lights will turn on when someone is using the space, this will reduce the costs of lighting being left on unnecessarily.
  • Use programmers to set times for heating and ensure that they run only when needed.
  • Setting the heating/air conditioning 1 degree lower in winter or warmer in summer (if you have air conditioning) can reduce their energy costs by up to 10%.
  • Energy monitoring using either a smart meter or a half-hourly meter can result in finding ways to reduce consumption through and spotting any anomalies and areas of wastage.
  1. Buy greener energy

There are energy providers that offer energy from a greener source:

  • Review your energy contracts. Search for an energy provider that can offer you both financial savings and electricity that is 100% renewable and reap the benefit of low bills and cleaner energy.
  • Try and explore green gas if possible when you review your energy contracts, it may not be a big saver (if any) but, it could really help your credentials and advancements in green gas development. This will increase its cost-effectiveness to make it more viable in the future.
  1. Could you generate your own energy?

Generating your own energy or heat could save you money and help the sustainability of your business. You can invest in:

  • Solar PV is the most widely suitable technology as many businesses have roof space that could be utilised.
  • Wind turbines are probably less feasible for most businesses, but they can offer a good generation of energy throughout the year and day.
  • Biomass boilers to produce heating and hot water can be a viable option for many businesses if your premises allow for it.
  1. Flexible and smart working

Many businesses are already taking advantage of more flexible working for their staff as a staff incentive, this can also help you reduce your environmental impact. Some suggestions are:

  • Allowing staff to work from home gives them the benefit of flexibility and as a business, you may reduce overhead costs and reducing transport emissions.
  • Fewer car journeys will reduce the wider impact that your business has on the environment. It can also elevate office space and parking.
  • Use technology to hold virtual meetings, this will reduce the number of meetings where staff need to travel. This will also reduce the number of mileage claims and reduce expenses budgets too.
  • Put in place a car-sharing scheme and give sharers preferential parking or other incentives to encourage fewer vehicles travelling to your business. This works for both commuting and work trips.
  • Set up a cycle to work scheme to encourage those who live locally to cycle instead of drive.
  1. More efficient vehicles

Can you reduce your fleet emissions and fuel consumption? Here are some ideas:

  • Compare vehicles to ensure that you get the lowest emission vehicles possible which will also cost you less to run.
  • When reviewing your fleet, assess whether electric vehicles (EVs) or hybrid vehicles could be an option as they have become more popular, affordable and viable as an alternative for many businesses.
  • Install EV charging points to help staff and customers with their own EV charging.
  • EVs and charging points are a very visual way of showing you are reducing your environmental impact as well as demonstrating you are a progressive and responsible business.
  • Some incentives and support may be available to help with EV charging points.
  • Also, if you combine EVs with solar PV, you could charge your vehicles for free.
  1. Create environment champions

Harnessing the enthusiasm or support of your staff in this journey to a greener business is an essential element as they can be your champions in your business to ensure that wastage (physical and energy) is reduced and to identify other initiatives or opportunities. This helps with:

  • Creating awareness with staff and getting them to bring ideas.
  • Introduce some healthy competition between teams or sites on reducing wastage.
  • They can be your eyes and ears to feedback on what works and what doesn’t as well as share best practice and new ideas.
  • And sharing the workload makes it easier for everyone.

The true cost of cheap lighting installation quotes

The true cost of cheap lighting installation quotes

When your business gets a range of lighting installation quotes, you might find that some of them can vary in price. And you may wonder why some companies are able to quote you one price and other companies a different price? But what makes up the differences in costs and what should you be looking for in those pricing structures?

If you do receive a dramatically cheaper quote, here are some things to consider when reviewing it:

Quality of lights

LED lights are made from chips that emit phosphor. Billions of these chips are manufactured and not all chips are equal in quality. The better the quality of chips in the LED light, the better the quality of the light. LED lights which are made from the lesser quality chips are cheaper to purchase but unlikely to last as long.

If a quote is significantly cheaper because of low-quality products, then you may also wish to consider whether you will get the right brightness or colour for your property, this is determined by the colour rending index. Colouring rendering index is a scale of how light can impact the colour of an object to the human eye, and lighting can be used to enhance a room and its environment using this index. Cheaper LED lights can emit different colours, make it more difficult to work with and even impact your productivity.

Changing the bulb

As the cost of the LED light goes down, so does the standards of cheaper lighting components. This is where savings are made in the short term. However, these lights have a shorter lifespan and the hidden costs can start to add up. What this doesn’t include is the cost of replacing the lights themselves. A cheaper bulb is only cost-effective if it doesn’t need to be replaced for the duration of a more expensive light lifespan.

You should also factor in the cost of the contractors needed to change the light. For every time an LED light reaches the end of its life, you need to pay for someone to install a new light. Lighting for commercial and public properties cannot be changed in the same way you would in your own home. You need a qualified technician to ensure the new light is properly fitted which comes with an invoice at the end.

Good quality LED lights have a guarantee of service and while the initial cost may be greater, in the long term it will save you money.

Replacing fittings

If your building is replacing older lights for new energy-saving LED lights, you are likely to need your fittings changing as well. Sometimes a quote can only refer to installing new LED lights into the existing fittings. Ensure that your quotes cover the replacement of any old fittings so that your LED lights do not burn out. LED lights placed in the wrong fittings are at risk of overheating and failing. Making sure your lights are installed correctly and snag tested is an important part of the professional lighting installation quote

Does quotes include disposal costs?

Quality of service

Getting the right contractors in the first place will give you the assurance your installation will be fit for purpose. Our specialist lighting installers understand that how the space is being used will determine the LED lights needed for the installation. Using a school installation as an example, the light needed for regular classrooms will be different for the light requirements in a woodwork room. The two rooms may be the same shape and size, even have the same amount of natural light but because they are used for different purposes, they have different lighting requirements.

The same is true for commercial buildings. Taking a business as a whole rather than looking just at the lighting installation is integral to providing a truly bespoke quote and good customer service. We know we do this well and have excellent feedback from our previous customers.

So, when you evaluate your lighting upgrade quotes it is best to ensure the whole job has been properly costed and the whole lifetime costs of the products chosen are transparent. Short-term savings often don’t weigh out the longer-term gains of quality LED lighting products.

LED Lighting – Five Reasons Why it’s a Bright Idea for your Business

LED Lighting – Five Reasons Why it’s a Bright Idea for your Business

Look up. Look around you. What do you see? If it’s anything less than a light and bright working space, you may have a problem.

Few people realise just how important the right lighting can be for our working environment. Even fewer realise how much money can be saved (and made) through choosing LED lighting.

In this blog, we explain how lighting can influence health, well-being and alertness, while also boosting business and saving money in the process.

1. Feel better. With better lighting.

Study after study has served up illuminating facts about how the lighting around us influences our mood. Perhaps the most fascinating of which, at least recently, has been related to the control of our biological clocks and the regulation of key hormones – such as cortisol and melatonin, through regular light and dark rhythms.

These hormones play differently with differing light. For example, blue-white artificial light can help concentration and boost productivity levels, while blue light is thought to lower melatonin, in turn making us feel more alert.

In contrast, warm yellow lighting can help people relax (so they’d be better placed in a residential or hospitality setting).

 2. All about the money? LED lighting provides bang for your buck

LED lighting not only cuts your lighting bills by between 60 – 80%, the bulbs also have an exceptionally long lifespan, coming in at 50,000 hours (up to 50,000 hours which is the equivalent of being used 12 hours a day for 16 years). Some even have lifespans of up to 100,000. In case you’re wondering, this means that LEDs last, on average, 35 times longer than a halogen.

3. Getting to work – Brighter lighting fuels productivity

There is endless research out there to back up the importance of a properly lit working environment. Many of these studies focus on the problems associated to poor lighting, which can lead to eye strain, fatigue and aching, which can then result in a deterioration in performance (Parsons, 2000, Nave 1984).

It’s not all bad news however. On the flip side, better lighting can lead to tangible improvements in productivity. Take Juslen’s study (2007), which found that when horizontal luminance was alternated per work shift (between 800 and 1200 lux) the speed of workers in a factory assembling electronic devices increased significantly under 1200 lux.

4. LEDs are kind to the planet

As a business, you’ve probably become more focused on corporate social responsibility in recent years. So you may welcome the news that LEDs are completely free from toxic compounds or elements such as mercury. As well as this, they are fully, 100% recyclable.

Put this all together and you could be looking at cutting your carbon footprint by up to a third.

5. And finally… LEDs are highly functional

LEDs offer unrivalled design flexibility – they can be retrofitted without major disruption and they play nicely with even the most ambitious of layouts. They can be dimmable, come in different colours and can be fitted with a distribution to suit your business and the different areas within it.

LEDs are INSTANTLY bright. You can switch them on and off, on and off, and their performance remains consistent. They can also work in the most extreme of temperatures – such as refrigerated rooms or warehouses (thanks to the fact that they’re mercury-free).

All in all, LEDs can be used to create functional, bright spaces, as well as areas that soothe, uplift, or energise.

Hopeful this blog has illuminated why the switch is so beneficial. And if you want to find out more contact us for a no-cost to you site survey to learn how LED lighting can improve your working environment and save you money.


5 ways to meet the minimum energy efficiency standards

5 ways to meet the minimum energy efficiency standards

The energy performance of a building is currently measured on a scale of A-G, with A being the most efficient and G the least. Since 2018 buildings need a minimum energy performance certificate (EPC) of E or higher for them to be compliant with minimum energy efficiency standards (MEES) in order to rent it out.

If you are leasing out your commercial property then you are likely to be looking for ways to meet the MEES for your building if it is not yet compliant.  You can find out more information on MEES here.

Improving the energy efficiency of your commercial property can seem complex at first.  This is why we have some simple solutions to improve the energy efficiency rating to help. Here are five different options that you might consider:

Solar Panels

If your building is suitable, you can use your roof space to add solar panels and reduce your electricity demand by harnessing the natural energy of sunlight. This will reduce your carbon footprint as electricity is produced using gas.  Instead, you can generate your own source of electricity during the daylight hours.

For buildings that have high electricity consumption, such as warehousing, this can reduce electricity costs and also improve your energy rating.


Switching your high-energy consumption lights for a low energy option like LED is a really simple way to improve the performance rating of your building. It also has an added bonus of improving the quality of lighting for your tenants.

Efficient boilers

Switching to energy efficient boilers and heating systems within the property makes a difference in the costs of heating the building and its EPC rating.

Individual boilers come with their own product rating so when installing a new boiler, you can check the efficiency rating with your professional installer as some are more efficient than others. Where possible, a renewable heating system is a good option to heat your premises.

There are government incentives available for renewable heat systems.


We know that getting people to turn out the lights when they are not using them is not always straightforward. Sensors can be placed in hallways, kitchens, and bathrooms to make it easier to ensure that lights are only on when needed.


By adding insulation to your building, you can reduce the heat loss through walls. This will reduce your energy demand as it will keep the heat in for longer. Equally, in the summer, it will help keep the heat out.

Check how well your external walls and ceiling are able to keep heat inside. Insulating drafts, roofing, and thinner walls with a blanket of wool-based padding or insulation boards. This will keep heat from escaping. Likewise, using double glazing will create an extra layer to trap the heat. This means your building will stay warmer for longer and you do not need to run your boiler as often.

Whether you use one or all of these to increase your EPC rating, you can be sure that they will save money in the long term. While you may not be the one paying the energy bills, commercial properties with lower bills are more attractive to potential tenants. Equally, by meeting the MEES you will be avoiding a potential fine.

Reduce, Reuse, Recycle

Reduce, Reuse, Recycle

Reduce, reuse, recycle – most of us will be familiar with this mantra urging us to consider our impact on the environment and create a positive change in the world.

Yet, it can sometimes seem overwhelming. The amount of information given to us about how to better live our lives with less waste is immense.

At Save Energy 2 Day, we get behind the saying that it is better for many people to be imperfectly striving towards zero waste than it is for few people to be perfectly zero waste. If everyone makes little changes, it will add up to a big difference.

It is nice to see local councils taking up this mantle too. We found this leaflet at a Leicestershire school where we recently had a meeting.

Harborough Plastic Pledge

Imagine if we all popped our plastic bottles into the recycling bin instead of the waste bin. How many lightbulbs could we power? How many towns and cities could we light up?


There is a reason that the first word in the three R’s is ‘reduce’. It’s because the most impactful thing you can do is reduce what you use.

Think about it: if you are not using something in the first place then you will not have a need to reuse it or recycle.

Going zero waste isn’t a new concept. Back in the 1970s groups around the UK were setting up what they termed ‘permaculture’. It is a term used to describe permanent culture, that everything we do has a natural cycle without the need for waste.

We don’t need to suddenly change how we live to start working towards zero waste. We just need to make some small changes.

One of those changes is using low-energy LED lighting, which has a longer lifespan than halogen or fluorescent bulbs.

Things you can do to reduce what you use:

  • Offer a lift to someone going to the same place as you so that you can reduce the number of cars being used
  • Take out a bottle or coffee cup when you leave the house so you don’t need to buy bottled water or use a takeaway cup
  • Buy local where you can, to help reduce air and road miles.


If we start looking at how we can reuse our things, we will create less waste. Can we send old clothes and books to second-hand shops? Is there someone we know who can make better use of some of the kitchen appliances that sit collecting dust in the cupboard?

Our habits have already changed over the past few years as we start carrying reusable bags, bottles and coffee cups.

Before we put our junk in the recycling bin or waste bin, is there another use we could find for it?

Things you can do to re-use what you have:

  • Make planters from leftover yogurt pots
  • Use cleaned food containers for food storage or packed lunches
  • Old socks make great dusters.


Over the past 20 years, we have really embraced recycling and made it as easy as throwing something in the bin. The more we think about our waste, we see more ways we can recycle rather than dump waste. Changes in how we think about our rubbish have changed dramatically but is there still more that we can do?

Things we can do to recycle more:

  • Donate old books and clothes to second-hand shops
  • Compost our food waste or use the contents of our tea bags on our small plants
  • Offer our broken appliances for parts on freecycle or to a local repair cafe.

Simple changes

More of an impact can be made with small, simple changes done by many people than large sweeping changes done by a few. We think of this as being imperfectly zero waste. When we add an extra way of reducing our environmental impact into our everyday lives, it becomes part of the routine and eventually, we don’t notice the thought or effort we once had to put into it.

Like the famous supermarket tagline: every little helps.


Why natural light will boost your child’s learning

Why natural light will boost your child’s learning

When it comes to illuminating rooms in which we spend large amounts of time, natural light is always a more pleasant experience. There is a good reason why we feel better when we learn or work in a space that has windows. It is not just because we like to stare out of them while we think or daydream.

Natural light has an impact on how our brain works. It doesn’t just affect our eyes or how we see, but also our hormone levels.

Our circadian rhythms – the natural, internal processes that regulate our bodies’ sleep-wake cycle – are influenced by the rising and setting of the sun. Therefore it makes sense that our hormones are influenced by how much natural light we are exposed to each day.

Natural light can help keep us alert but it also tells our bodies when it is time to calm down.

How does this help in a classroom setting?

When we make the most of the natural light in classrooms, children are more alert because their bodies release a hormone called cortisol. This is what makes us feel awake.

If children are more alert, they are able to concentrate. A recent study in the United States found that over the course of a year, children who had more natural light in their classrooms had 26 per cent higher reading outcomes and 20 per cent higher maths outcomes than children in classrooms with less natural light.

Blue Light

Of course, it is not possible for all classrooms to be bathed in natural light. That does not mean that those children should be at a disadvantage as a result.

It is blue light which tells the body to release the cortisol so where natural light is limited, a different blue light source can be used. Supplementing natural light with LED lighting that has a blue colour temperature will boost blue light waves. This, in turn, will support children’s learning where there is not an abundance of natural light, creating the best possible learning environment for children.

Blue light is also emitted from digital screens, which is why many studies recommend limiting screen time before bed. It can raise cortisol levels and thus disturb our sleep patterns.

More Benefits

Natural light in classrooms also has other benefits. It also has a known effect on our moods. In the classroom, it can support children who are susceptible to low moods and have a positive impact on the mental health of all pupils.

Access to natural light also helps with sleep. Our bodies know that when the sun sets, it needs to produce more melatonin, the sleep hormone. This relaxes us into the night. As a result, children are more rested and ready for their next day at school.

If we get the most out of the natural light in classrooms, children will have better concentration and better outcomes. Where there is limited natural light or through the darker, winter months, this can be substituted with blue light sources such as LED for similar results.

Case study: The Bemrose School

Case study: The Bemrose School

LED lighting replacement projects aren’t just about saving money. Organisations often are looking to improve the physical environment too, inside and out.

This was the case at The Bemrose School in Derby, where much of the lighting was “old and energy hungry”.

Site Manager Malcolm Strange explains: “We were looking for more efficient and energy-saving LEDs to improve the lighting in the school itself, and on the walkways and external areas around the building.”

The issue was both the brightness level and the colour of the light given out, or ‘colour temperature’.

As Malcolm explains, “Our external lighting was of a type which needed to ‘warm up’ for a period before reaching its full brightness and it gave out an amber light, casting shadows and leaving dark unwelcoming areas.

“Internal lighting also felt gloomy and dull, particularly in rooms which received less direct sunlight.”

A governor had heard of Save Energy 2 Day and suggested the school get in touch about replacing the outdated lighting with LEDs.

Onsite survey

Once Malcolm got in contact with us, we carried out an onsite survey to assess the best lighting options and the potential savings on energy costs.  

We worked with the school to ensure lamps and fittings were the right brightness and colour for each setting. We also sourced high quality, flicker free lights to reduce the risk of eye strain and headaches. (Find out more about the benefits of flicker free lights).

To cover the upfront installation cost, we helped the school successfully apply for Salix Finance. We then carried out the work during the half term break.

Said Malcolm, “The teams which worked at the school were cooperative, conscientious and polite. They all worked hard and achieved a massive amount in a relatively short time available during the school holiday period.”

“The work they have done appears to be of a high standard. Each area of the school they worked in was left clean and tidy when they moved onto the next.”

Improved physical environment

Not only has Bemrose reduced its energy use, the physical environment is much improved, inside and out.

“The external environment is now brighter, more welcoming and friendly,” said Malcolm. “We have received positive comments and thanks from those who use the school during the evenings, as the paths and walkways are well lit.

“The light levels in the classrooms are far better. The light is a cleaner, brighter light but isn’t glaring or harsh. Everyone notices the change without necessarily realising how it has come about.”

Why we are passionate about making changes in lighting and the environment

Why we are passionate about making changes in lighting and the environment

Today’s children are set to inherit a world where ecological diversity is shrinking and that could have dire consequences. This, along with climate change and plastic waste will have a real and noticeable effect on the quality of life for today’s school children.

Make a difference

We believe that small changes can make big differences. Using less energy, recycling more, being smarter about transport and being careful with our waste can reduce our impact on the world.

We know that as a society, we are not going to wake up tomorrow and start making these big life changes in one fell swoop. But we are making progress.

Almost 20 years ago in the UK, only 12% of household waste was recycled, even though over 60% of what we threw away was recyclable. In 2017, over 45% of household waste in the UK is recycled.

Today, recycling plastic bottles, tins, card, and food is as easy as throwing it into a household bin. Something that was once seen as an effort is now a normal part of our lives. And we know we can do even more. For instance, Wales is aiming to become zero waste by 2050.

Every little helps

By making small changes to how we live, we can make a bigger impact on the world. If we slowly introduce these changes into our lives we are more likely to stick at them. This is about changing our habits on a permanent basis.

Things we can do include:

  • Insulate our homes
  • Check if we can recycle our waste before we put it into the bin
  • Turning our thermostat down by a couple of degrees
  • Using sensors on lights in the workplace or school
  • Turn off plug sockets and electrical equipment when they are not being used
  • Grow plants that attract bees to encourage the biodiversity needed
  • Send our old clothes to recycling rather than landfill.

In a previous blog we looked at more ways we can make energy savings.

And of course, installing LED lights is a small change that can make a big impact on reducing energy usage. Our hope is that in the not too distant future, every school and every office building in the country will have LED lighting. It may seem like a little thing, but together we can make a big difference in ensuring clean air, a stable climate and healthy biodiversity for future generations.

How this one switch in school can reduce CO2 emissions

How this one switch in school can reduce CO2 emissions

For us, one of the most exciting parts of installing LED lighting in schools is seeing how much CO2 can be saved as a result. In fact, one recent meeting with a school started us thinking just how much difference could be made if every school in the country made the switch to LED.

How do LED lights save so much CO2 in the first place?

CO2 is created when we generate electricity, which then feeds into the lights we use. The more electricity needed to generate the light, the more CO2 is produced.

With traditional lightings, such as fluorescent and halogen, more electricity is needed to light the bulbs, therefore, more CO2 is produced when they are used. If we switch out these lights to LED then there is less electricity needed to produce the light and less CO2 emitted into the atmosphere.

So, if every school were to switch out its fluorescent lights for LED lights, it would be a way of significantly reducing CO2 emissions in the UK and contribute to the target of zero emissions by 2050.

Let’s look at the figures

As an example, let’s say on average that a school can save 20 tonnes of CO2 every year using LED lights. This can differ depending on the situation, the number of lamps used, the type of lamps and how long they are switched on. Some schools may save more and others less.

There are just over 32,000 schools in the UK. If we use these conservative figures, that is a saving of 640,000 tonnes of CO2 emissions every year.

So what does this mean?

640,000 tonnes of CO2 is a figure that not many of us can relate to. If we can’t relate it, we can’t understand what that really means in our world.

This is the equivalent of over 5,000 acres of forest, (which is about the size of 2,500 football pitches). An acre of forest contains around 40 trees, which produce 260lbs of clean air every year.

5,000 acres of forest would give us 23,000 tonnes of clean air every year. This is the equivalent of 2,421 children breathing clean air every single day. Or of almost 7 children having clean air for an entire year.

If you want to know more about the impact of poor air quality on children’s lung development, you can read about it here.

As a nation, if we are to meet the target of zero emissions by 2050 then we all need to do our bit. The good news is that changing our lighting habits is a simple and easy way to reduce CO2 emissions.
