The greenest energy is the energy we don’t use

The fact that Bill Gates’ .. book does not focus on energy efficiency – while giving nuclear energy a large and not very imaginative role – slightly annoys me. [ed. only slightly?] Because decision makers, young people, and many others will read the book and draw the wrong conclusions. But also, because it feels like a symptom of a broader issue: intellectually it is evident for most people that energy efficiency is a central, cost-effective and economically smart way to contribute to the green transition. Yet energy efficiency does not play a central role in many countries’ efforts to secure a green transition. It is as if they overlook the fact that the greenest and cheapest energy is the energy we don’t use at all

The greenest energy is the energy we don’t use, energypost.eu 

November 12, 2021 by Martin Rossen   As COP26 comes to a close, Martin Rossen, Senior Vice President, Head of Group Communication and Sustainability at Danfoss reminds us in a powerfully persuasive way why the most direct route to net-zero is managing consumption. Inspired by a glaring omission by Bill Gates in his recent book, Rossen draws our attention to the futility of developing new tech if we don’t prioritise making use of readily available energy efficiency solutions. According to IEA figures almost half of emissions reductions must come from efficiency and the solutions are already at hand. Article promoted by Danfoss.

The Glaring Omission

The summer of 2021 was the first time in a while that I not only felt the urge but also had time to read a book. No more government files and committees. I read Microsoft founder Bill Gates’ newest book “How to Avoid A Climate Disaster: The Solutions We Have and the Breakthroughs We Need.” …………

However  ……. Bill Gates basically ignores that the greenest and cheapest energy is the energy we don’t use. I will get back to that, but let’s first look into climate action according to Bill Gates:

Primary Energy Consumption virtually unchanged through 26 years of COPs…….   According to the British economist Helen Thompson, fossil fuels constituted 86% of the world’s primary energy consumption when COP1 was held in Berlin in 1995. What is the progress today, 26 years later? The answer is almost nothing. According to the latest numbers, fossil fuels now constitute 84% of the world’s primary energy consumption.

………Reversing the Energy Density Trend

Czech-Canadian environmental researcher Vaclav Smil, of whom Bill Gates is big fan, says the underlying challenge is the fact that humanity historically has moved in the direction of more and more energy-intense energy sources……….

Bill Gates encourages decision makers around the world to make big investments in new technologies. …….

IEA’s “Green Equation”

So, what’s the plan, I’m tempted to ask? To a large degree, I agree with Bill Gates’ conclusions – but I can’t help being a bit disappointed by the fact that he essentially ignores the importance of energy efficiency to the green transition. Bill Gates briefly mentions that energy efficiency could make the green transition easier, but after that, it is left out of his analysis.

Yet the International Energy Agency (IEA), a central source in the book, mapped out the cheapest and most effective path to reach the goals of the Paris agreement – let’s call it the green equation – like this: 36% of carbon reductions must come from renewable energy, 2% from switching fuels, 6% from nuclear power, 9% from carbon capture ands, 3% from other sources – and the biggest chunk, with a total of 44% reductions, has to come from energy efficiency. In other words, we can’t merely build windmills.

The world’s energy consumption has risen dramatically since 1945. For each day that passes, the green transition challenge we face is growing …………  it is important we become better at creating more societal value by using less energy, for example, by recycling it.

Now to the good news

Solutions already exist. In Denmark, we know that. We often live in an energy efficient manner – in bright, well-isolated homes with a secure water supply. This didn’t come by coincidence, but out of necessity.

During WWII, the Danes rationed. This included use of energy, so the living room temperature was to be kept at about 18 degrees Celsius. On a farm on the island of Als in the corner of Denmark, Danfoss’ founder Mads Clausen had the idea to develop a thermostatic expansion valve, which automatically keeps a constant temperature. The result? An improved indoor climate in millions of homes all over the world, as well as energy bills and emissions that have dropped. It was a green breakthrough before we knew we needed it. Today, the island of Als is one of the global centers of energy efficiency.

The solutions vary, but at their core, they are the same – they provide energy efficiency. According to the IEA, these are the solutions to be put into play if we are to overcome the many barriers on the road to climate neutrality………..

 even in buildings with thermostats, heat pumps and other energy efficient solutions, we must take action. We need to equip our buildings with ‘intelligent’ systems – a ‘brain’ that links the buildings’ thermostats, heat pumps and air conditioning – as well as any other cooling and heating appliances– to big data that constantly optimizes energy consumption. The modern thermostat includes all factors in the equation – including the weather, showering habits of the inhabitants and expensive peak hours – and adjusts the consumption of energy accordingly. With solutions like this, according to the consultants ECOFYS, we can reduce CO2 emissions in Europe by 156 million tons – equaling the emissions of 82 million cars.

Industry, Transport and Food distribution

The industrial sector consumes a lot of energy and is responsible for one-fourth of the world’s emissions, so this sector demands our focus, too. Electric motors are a good place to start. In Europe alone, there are eight billion in use at the time of writing this. However, most of them only have two functions: they are either on or off. If electric motors were fitted with AC drives that enabled them to have adjustable speeds, the world’s demand for electricity could be reduced by 8%, according to the IEA – corresponding to the combined demand for electricity of India and France.

And then we have the transport sector that accounts for 24% of the world’s energy-related CO2-emissions. If cars are to be powered by electricity instead of gasoline, batteries and drives need to replace the combustion engine. This means that the gearbox of the future is a power module that converts power so the car can drive at various speeds. That movement is already on the way. What few people know is that Danfoss’ power modules already are installed in about 40 million cars, but there is still quite a way to go to replace the world’s 1.5 billion cars……….

Massive amounts of the world’s resources go into the production of food that is lost or wasted in areas without proper cooling facilities. In India, more than a third of food is lost on the journey from fields to the hungry population. It isn’t hard to imagine farmers’ disbelief and frustration in the face of this inconceivable loss of value. In many developing countries, proper cooling facilities in the supply chain can reduce the blatant waste of food (and associated emissions) by up to 40%, according to estimates.

The Solutions are already at hand

These are big numbers, and I could go on, because it is the same in practically the entire economy. We are not using our energy wisely. This results in a massive waste of energy. It costs fortunes on the energy bills of families and companies all over the world. It results in the emission of many billion tons of greenhouse gasses. And it makes the renewable energy infrastructure bill much bigger than it has to be.

We need to take this in hand, particularly in the Western World. It is necessary if we are to reach net zero. But also, because net zero is a zero-sum game, imposing a certain responsibility on us. We need to make an extra effort in the green transition so developing countries are not held back in their efforts to reach the same level of prosperity that we are privileged with.

Luckily, there are various energy-efficient solutions from many competent companies, that have a payback time of only a few years. That’s good because there is plenty of work to be done.

According to the IEA, the steam has gone off investments in energy-efficient buildings, equipment and vehicles. Both literally and figuratively speaking, we are wasting our energy at the same time we should be doing the exact opposite. It is a huge challenge many seem to forget: the green transition, in a lot ways, neither requires technological breakthroughs nor revolutions. It simply requires that we apply readily available cost-efficient solutions – not the least within energy efficiency.

The fact that Bill Gates’ .. book does not focus on energy efficiency – while giving nuclear energy a large and not very imaginative role – slightly annoys me. Because decision makers, young people, and many others will read the book and draw the wrong conclusions. But also, because it feels like a symptom of a broader issue: intellectually it is evident for most people that energy efficiency is a central, cost-effective and economically smart way to contribute to the green transition. Yet energy efficiency does not play a central role in many countries’ efforts to secure a green transition. It is as if they overlook the fact that the greenest and cheapest energy is the energy we don’t use at all. https://energypost.eu/the-greenest-energy-is-the-energy-we-dont-use/

The role of efficiency and smart grids in conserving energy

Australia, Indonesia, Japan and Nigeria have joined a collaborativeinitiative steered by the UK Government and the International Energy Agency (IEA) aimed at drastically improving the energy efficiency of appliances such as lighting, refrigerators and air conditioners.

“IEA analysisclearly shows the importance of energy efficiency for reaching net zero emissions globally,” Fatih Birol, the IEA Executive Director said. “Policies to improve the efficiency of products have already helped halve the energy consumption of major appliances in many markets, allowing consumers to benefit from significant savings while also loweringgreenhouse gas emissions.

 Smart grids

 What Is a Smart Grid, and How Might One Protect Our Energy Future? Our electric grid is old and fraying, but new technology could insulate us from the possibility of widespread blackouts and cyberattacks. In February 2021, an electric grid failure in Texas caused more than 4.5 million homes and businesses to lose power. Months later, wide-scale droughts and wildfires threatened the western US with rolling blackouts. With new energy sources such as wind and solar power, maintaining a steady balance gets even more complicated. This is because power from these sources is inconsistent.

“Smart grids” sense small imbalances faster, making adjustments so problems don’t get larger. They use sensors to constantly measure the status of different parts of the grid, and a series of devices that control the current flowing through different points. The sensors and controllersare run by computers that make automatic adjustments to maximize efficiency.
