Action on energy efficiency requires both technological and social change

Although sometimes overlooked in the race to devise innovative solutions to the climate crisis, energy efficiency remains crucially important. Energy efficiency has contributed to greater savings in primary energy and faster reductions in emissions compared to the transition to renewable energy resources. While the growth in global energy consumption dropped by 2.1% during the pandemic year of 2022, the growth rate remains higher than the average rate measured from 2010 to 2019. What can we do to slow this rate of growth, or even reverse it?

One of the best ways to take immediate and effective action is to transition from conventional lighting to energy-efficient LED lighting. LED light sources consume less than half the energy consumed by incandescent and fluorescent light sources, and up to 80% less energy when managed in a connected system. An individual light bulb or luminaire consumes a small amount of energy, but since lighting is everywhere that people are, the global lighting footprint is significant.

This means that transitioning to energy-efficient lighting solutions can have a significant effect. Since economic growth results in global increases in the use of artificial lighting, inaction will result in a significant increase in global energy consumption for lighting by 2030. While the global transition to energy-efficient LED lighting is moving very quickly—approximately 85% of lighting sales at Signify are LED today, for example—there are still significant benefits that can be gained by accelerating the depletion of the installed base of conventional lighting, which still accounts for almost 50% of all light points in the EU and the US. In fact, the worldwide switch to LED and connected LED could decrease global energy demand for electricity by 30%, while at the same time reducing carbon emissions by 1.4 billion metric tons a year. The switch is easy and relatively inexpensive to make, in both residential and commercial built environments.

It is important to keep in mind that making the transition to energy-efficient lighting involves not just technological change but also social change. People should be willing to make the switch. Individuals have to understand the positive effects of well-managed LED lighting on comfort and well-being. Businesses and cities have to understand its advantages not only in terms of energy and emissions reductions but also in terms of improvements to operations and quality of life.

A sense of urgency is appropriate. But fearmongering and finger-pointing will not bring about the necessary social change. Instead, the emphasis has to be on taking effective energy-efficiency action and improving the quality of life, work, and the economy. With the right approach, we can have our cake and eat it too.

It’s time to unlock the demand side potential in accelerating the energy transition.

In recent months the term “polycrisis” has found its way into our vocabulary. This term captures the multiple crises (climate; energy; inflation; war in Ukraine; …) that are impacting society at large. A sobering reality is that all these crises were created by mankind, as we use the wrong energy and waste too much of it, thus paying far too much in powering our economies and living our lives. On the flipside this means that as mankind we are in the driver’s seat in tackling these challenges. The good news is that the solutions are also interrelated and have raised the relevance and awareness of the energy transition to efficient and clean technologies.

Much attention goes out to the “supply side” of the energy transition, both on the energy mix (with ongoing high use of coal; a search for alternative gas supplies; scaling renewables; investments in hydrogen and nuclear) and energy intensive industries with large stimuli programs in Europe and the US (the Green Deal Industrial Plan and the Inflation Reduction Act). Yet the structural changes to decarbonize our energy system at the supply side of the energy transition will need time to reach scale and impact.

As the world needs solutions on a much shorter term, the time is right to unlock the vast potential at the “demand side” of the energy transition. This largely comes down to stepping up our collective efforts on energy efficiency.

The electrification of heating, transport and other service systems require a massive amount of electricity. The average global electricity consumption of a household (3400 kWh) is almost exactly equal to the annual amount of electricity needed to charge an electric vehicle or to power a heat pump. Already the grid is close to a point where countries are at or near capacity.

For example, while the lighting sector is positively known for the transition to LED lighting, lighting alone still accounts for 13% of global electricity usage. Importantly around half of all light points in the US and EU are still conventional, offering an enormous opportunity for rapid reductions of lighting-related energy consumption. LED lighting retrofits are relatively fast and easy, with few invasive activities involved.

Through a complete switch to connected LEDs, the EU has the potential to save €65.1 billion in energy costs annually and mitigate 51 MTons of carbon emissions, while freeing up enough electricity to power 47 million heat pumps and thus keep a quarter of all households warm each year. The reduction in carbon dioxide would be equal to the sequestration capacity of a forest the size of Switzerland.

Like for lighting, many other solutions exist and Europe’s “demand side companies” operate at the cutting edge of active and passive energy efficiency technologies including lighting, building management systems, sensors, controls, insulation, windows and many others.

Energy efficiency technologies can generate savings often called “low-hanging fruit” waiting to be picked, so let us roll up our sleeves and pick those fruits for the benefit of Europe’s competitiveness and the well-being of its citizens.

The need for speed | EUSEW 2021

by Harry Verhaar Head of Global Public & Government Affairs and Chairman of the board of the European Alliance to Save Energy.

In this climate-critical decade, Europe is faced with the extraordinary task of drastically improving our environmental impact, while also repairing economies left shaken by the effects of COVID-19. Now is not the time to split our priorities: the actions we take to mitigate climate change and those we take to accelerate economic recovery must work both in harmony and at pace.

Both effectively and economically, energy efficiency improvements are the best strategy at our disposal for a swift reduction in carbon emissions. With buildings accounting for 40% of energy consumed and 36% of energy-related greenhouse gas (GHG) emissions, the European Commission’s Renovation Wave strategy gives us an excellent foundation on which to start.

Everything that can be done to improve the footprint of our buildings, should be done: insulation, modern heating, ventilation, and air conditioning (HVAC) technology, and digital solutions like building management systems that can monitor and optimise energy expenditure. Among these key improvements, we should not forget one of the quickest wins: lighting. Two-thirds of installed lighting is legacy technology, with 1.3 billion conventional light points across Europe that could be switched to LED. Through this alone, the EU could save around EUR 40 billion and eliminate 100 million tonnes of CO2 emissions a year. This quick, simple, and low-cost intervention comes with relatively little disruption to the building’s occupiers, and the payback is fast.

Increasing renovation rate and depth will positively impact economic growth, investments, innovation and competitiveness, and lead to a reduced reliance on fossil fuels, in turn improving Europe’s energy security. And economically, the impact of building renovation will most benefit the local SMEs who make up more than 90% of companies in the building sector. Accelerated activity on this level creates jobs for those with displaced incomes due to the global pandemic.

The European Green Deal: a tipping point for good

by Harry Verhaar, EU-ASE Bord Chair and Head of Public & Government Affairs at Signify

It’s been a grave winter for the health of our planet. In Madrid, urgent climate talks dissolved into a disappointing stalemate. The public is informed and engaged in a new and promising way, but is also more divided. We are close to a tipping point: a point at which the rate of change increases dramatically, and possibly irreversibly towards a climate catastrophe.

When we talk about the concept of tipping points, we recognize that change isn’t linear – it’s exponential. We see examples of this all too frequently. As the planet warms, Arctic permafrost thaws, releasing methane and carbon dioxide that further accelerates the pace of change. And as the Earth loses more and more of its white, reflective surfaces, the planet more readily absorbs heat. We’re close to some of nature’s tipping points. Reaching these would have disastrous implications for our planet and our way of life.

Man on the moon moment

But in Europe, a change is coming that could be crucial to containing our carbon emissions and limiting the effects of climate change. On December 11, 2019, the European Commission announced the European Green Deal, a set of policy initiatives aimed at making this continent carbon neutral by 2050. The European Commission’s president, Ursula von der Leyen, called it Europe’s “man on the moon moment.”

The world’s track record with climate regulation has been patchy at best. So, what’s different about the European Green Deal? For me, it marks a fundamental change in the way environmental and sustainability regulation is developed. Historically, change that is focused upon carbon emissions reduction or environmental protection has been weighed in terms of expense: what must we sacrifice to achieve these targets? This tends to shut down public and political discussion, and in my view, has critically undersold the opportunities that sustainable practices bring to the table.

Growth strategy

The Green Deal is not about penalizing businesses and people for doing things in a less sustainable way. It’s a growth strategy, integrated into every public policy plan, that hardwires a preference for sustainable initiatives into every aspect of Europe’s socioeconomic development.

This is an important distinction. When you look more deeply at sustainable solutions, you discover that they are not at odds with economic progress. They are, in fact, better in every way. Take LED lighting. It’s more resource-efficient. Less burdensome on the environment. It costs less over a lifetime. And it is better for people, helping to improve quality of life. It can reduce road traffic accidents, deter crime, make you more productive, contribute to you breathing cleaner air. Who would say no to that?

We’ve said before that as we move into this all-determining decade of climate action, the time for talk is over. The European Green Deal presents a clear and non-negotiable ambition: to be climate-neutral by 2050 at the latest. To get there, we need intermediate milestones too, and that means a cut in emissions of more than half by 2030. This is in line with the recommendation of the Intergovernmental Panel on Climate Change, which advised a reduction of at least 55% by 2030.

 

“A climate neutral goal without action is dreaming.
Climate Action without a clear goal is sleepwalking.”

 

To have our “man on the moon moment”, we need to walk the talk. At Signify, we have our own carbon commitment, to be carbon neutral by the end of this year.

We also call upon others to adopt programs like the Climate Group’s RE100 commitment to renewable energy, to participate in renovation programs that transform existing buildings into net zero carbon buildings, and to adopt a 100% electric vehicle goal for the corporate or the municipal car fleet, because doing these things brings with it progress. It demystifies climate action, it turns ambition into concrete steps, and it demonstrates the economic potential of a new and better way for our society to function.

Progress is not linear

Programs that start with only a few participants have the power to make a difference. We know that the detrimental effects of climate change on our planet are not linear, but the same can be said of our progress. History has shown that many transitions accelerate after reaching a certain momentum. We see this in the lighting sector. At the end of 2006, incandescent light bulbs were still two thirds of our sales volume. In our last quarter, more than 80% of our revenue came from sustainable products, systems and services. The world has more people, bigger urban populations, and more light points than ever before, yet the proportion of global electricity consumption from lighting falls each year, from 19% in 2006, to 13% in 2018, and we expect it to fall further to 8% by 2030.

What happened? LED reached a tipping point. This successful decoupling of electricity consumption from use of light shows that choosing for sustainability does not need to come at a cost. This is just one example of such a decoupling – there can be many more. If we can achieve energy savings on such a scale across buildings, transportation, industry, our targets will be easily met.

To my mind, the European Green Deal can be our tipping point for good. With its broad scope, it reaches into the areas where we can have the most significant impact, and within these, create further tipping points for good. It can change the way we approach regulation. It can prove to the world that sustainability and economic growth need not be at odds. And it can be a time we look back on as the moment when we joined together to divert our path to a better and more sustainable trajectory.

The age of Sustainalism: a new growth model for the 21st century

By Harry Verhaar, Head of Global Public & Government Affairs at Signify and Chair of the EU-ASE Board.
This article was originally published in COP 23 | Climate Change – the New Economy.

It is becoming ever more clear that the major global trends which are having the greatest impact on the world around us are not only increasingly intertwined, but are also becoming ever broader in their impact, affecting a greater number of regions and citizens.

Global hunger is on the increase, for the first time in over a decade. According to the annual United Nations report on world food security and nutrition, this increase is primarily due to climate-related shocks and the growth in the number of violent conflicts. The report also points to concern at the number of overweight children and obese adults, with changes in dietary habits and economic slowdowns cited as some of the drivers of these trends. The authors of the report state that the world will not “end hunger and all forms of malnutrition by 2030 unless we address all the factors that undermine food security and nutrition. Securing peaceful and inclusive societies is a necessary condition to that end.”

We need a paradigm shift – slightly revised capitalism or moderated socialism are not going to suffice.

The impact of climate change has thus far been most keenly felt by the citizens in the developing world. However, last year’s intense and destructive hurricanes, which tore through the Caribbean and then hit the southern United States, suggest that even the wealthiest country on the planet is not immune to the consequences of a changing climate.

It should be clear that we cannot continue to look at the challenges facing the world in isolation. It may be comforting to do so, as focusing on a single issue can provide for greater clarity and easier communication. But this approach has the danger of simply storing up trouble for future generations.

Our focus on measuring global success through GDP growth has trapped us in a linear view of society – focused on extracting, consuming and emitting resources from energy to water, materials and food. We need to become much smarter, more resource-efficient and change from a linear approach to a circular society, in which long-term quality of life becomes the most important metric. This would ensure that while economic competitiveness remains important, our society would have at its core the health and well-being of all our citizens.

By adding a focus on social equity and inclusiveness, we can enter an age where the socio-economic model becomes about Sustainalism, building on the foundations laid by capitalism and socialism, but taking the broader view which the challenges of today and tomorrow demand of us.

No one is unaware of the need for our products and processes to become more energy efficient and yet, often due to a focus on the short term, there remains a reluctance to make the transitions required.

To arrive at a carbon-neutral world by 2050, we need to drive overall energy efficiency improvements of at least 3 per cent per year. “We” – industry, transport, public infrastructure, homes – must at least double the rate of energy efficiency improvement, primarily by accelerating infrastructure renovation to around 3 per cent per year. In parallel with this we also need to be moving to clean energy sources at a rate that also equates to 3 per cent of our energy mix per year.

Critically, the current rate of energy efficiency improvement hovers at around 1.5 per cent per year. At the same time, demand for energy continues to rise at about 3 per cent per year driven by population growth, increased prosperity and mobility. Simply doubling the rate of energy efficiency improvement would reduce global energy costs by more than $2 trillion by 2030, slash the average household energy bill by a third, and create more than six million jobs by the end of this decade.

Simply adopting LED in place of incandescent lighting would reduce energy consumption by a massive 53 per cent and carbon dioxide emissions by 1,400 megatonnes.

There are two main elements required to double the rate of energy efficiency improvement. The first is accelerating the renovation of existing infrastructure in developed countries. Secondly, there needs to be a focus on helping developing countries leapfrog to clean technologies such as solar-LED and combine these with new business models. It is a sad fact that many of the countries which have suffered the most from climate change have been least responsible for creating it. It is vital that developing countries do not follow the same destructive phases that the richer nations of the world have been through.

When speaking about energy we often talk about individual technologies and their potential in their respective silos. In reality we must pursue them all. Energy efficiency, renewable energy and carbon engineering are all needed. Only by enacting all of them in unison will we be able to achieve the ultimate goal of carbon neutrality in the coming 40 to 50 years. The International Energy Agency projects that energy efficiency needs to do over half of this job. One could say that by combining energy efficiency and renewable energy we can decarbonize society twice as fast and twice as cost-effectively.

The fact is that many of the technologies we need already exists, all that’s required is to take a longer-term view, and use it.

LED lighting is a perfect example. LED street lighting uses at least 40 per cent less energy than conventional lighting and has been around for years, and yet we still cling to outdated and inefficient technology. Globally, lighting accounts for about 15 per cent of all electricity consumption. We project this will decline to 8 per cent in 2030 while over the same period the global tally of light points will have increased by 50 per cent to 70 billion. Simply adopting LED in place of incandescent lighting would reduce energy consumption by a massive 53 per cent and carbon dioxide emissions by 1,400 megatonnes.

Moreover, innovation brings benefits beyond energy efficiency. Looking at lighting specifically, around one in seven of the world’s population (some 1.1 billion people) are trapped in light poverty because – cut off from the grid – they have no access to electric light. As a result, they are forced to use alternatives such as kerosene lamps and candles to light their homes – which claim an estimated 1.5 million lives every year through respiratory illnesses and fires.

But off-grid solar LED lighting solutions can help to end this injustice, at a fraction of the long-term cost of kerosene or typical infrastructure, while stimulating social and economic development as communities are brought out of the dark.

However, in all these cases what can hold the development back is the initial upfront cost. The cheapest individual lightbulb to buy remains the incandescent bulb – yet viewed over any length of time, it becomes the most expensive.

It is also extremely limited technology. In contrast, LEDs can now be embedded with sensors and intelligence so they can be connected wirelessly and managed remotely via the internet. This connected lighting for smart buildings and smart cities can further boost the initial energy savings by up to 80 per cent.

The benefits of this connected technology can be measured in much greater terms than simple energy savings. Businesses can enable employees to personalize their lighting and temperature at their workspaces via a smartphone app, with associated improvements in both productivity and employee well-being. In addition, building managers can receive real-time data on how the office is being used, how much space is required, and how to optimize the space they have.

The benefits of connected lighting can be seen on a city-wide scale. For instance, the City of Los Angeles has converted 140,000 street lights to LED and has 110,000 nodes connected and managed through a Philips Lighting CityTouch connected street lighting management system. Not only does this allow the city to remotely manage and monitor the lighting, acoustic sensors can be used to detect vehicle collisions and thus reduce the emergency response time. Other benefits include a 21 per cent reduction crime in areas where the improved lighting was introduced and a 30 per cent reduction in night-time traffic accidents.

We need to become much smarter, more resource-efficient and change from a linear approach to a circular society, in which long-term quality of life becomes the most important metric. 

Buenos Aires is another city that has retrofitted its street lighting system with connected LED lighting, creating a safer, more welcoming environment to improve the quality of life of its residents, while also saving 50 per cent in operating costs.

Better lighting can also have a significant impact in schools. In a year-long trial in a French primary school, a new system that allows the teacher to optimize the classroom ambience found that reading speed increased by 35 per cent, while frequency of errors dropped by nearly 45 per cent and hyperactive behaviour by 76 per cent. All of these factors can provide a major boost to children’s enjoyment of their school day and their ability to learn.

The key in encouraging the adoption of this type of technology is delivering the message that it does not require a sacrifice, or that we are looking at experimental concepts, but that the technology is already available and simply needs accelerating. This must take place through replicating best practice, putting the right policies in place, and communicating effectively.

We need to convince society’s “eco-majority” – those who are aware of the need to act, are willing to do so, but are uncertain about the steps to take. Creating momentum with this group will help embed Sustainalism as the new mainstream economic model.

We need a paradigm shift – slightly revised capitalism or moderated socialism are not going to suffice. We need Sustainalism, a new, inclusive and more equitable socio-economic model of a twenty-first century that can meet the needs of the 10 billion people who in just a few decades from now will  share the single planet that we call home.
