Mitigate climate change the energy efficient way

Since 2007, the Danish city of Sønderborg has managed to reduce 52 per cent of carbon emissions and foresees to achieve 100 per cent energy efficiency by the year 2029. A model for Denmark and Europe, this city is aptly chosen as the host for the IEA’s Seventh Global Conference on Energy Efficiency, where world energy and climate leaders are gathered for a major ministerial meeting to drive urgently needed improvements in energy efficiency, with new analysis by the International Energy Agency showing that stronger efficiency measures can reduce energy bills, fuel imports and greenhouse gas emissions quickly and significantly.

With the world contending with its biggest energy crisis since the 1970s, the focus of the conference was on how to implement measures quickly to reduce energy use, with the aim of easing cost pressures on consumers, cutting reliance on fuel imports and driving progress towards climate goals — while supporting job creation and economic growth.

The new IEA analysis, published to coincide with the global conference, underscores the vital role of energy efficiency and energy saving in meeting today’s crises by immediately addressing the crippling impacts of the spike in energy prices, strengthening energy security and tackling climate change.

Fatih Birol, executive director, IEA, said: “Energy efficiency is a critical solution to so many of the world’s most urgent challenges — it can simultaneously make our energy supplies more affordable, more secure and more sustainable. But inexplicably, government and business leaders are failing to sufficiently act on this. The oil shocks of the 1970s set in motion major advances in efficiency, and it is utterly essential that efficiency is at the heart of the response to today’s global energy crisis. The leaders meeting at the IEA Global Conference on Energy Efficiency need to make this the moment when the world hits the accelerator on efficiency — or we may fail to respond to the current energy crisis properly and pay the price for years to come.”

He added: “We are facing the first global crisis in oil, gas, coal and electricity. Prices are at unacceptable levels. There is a growing worry for both natural gas and oil markets. This is why the IEA has come up with a 10-point strategic principle to expedite energy efficiency policies globally.”

Stressing on the urgent deployment of efficiency tools, Birol added that energy efficiency is possible with existing technologies if best practices were followed by users.This year’s global conference is jointly organised by the IEA and Denmark’s ministry of climate, energy and utilities, with support from Danish engineering company Danfoss.

Dan Jørgensen, Denmark’s minister of climate, energy and utilities, said: “Sønderborg is the perfect place to be right now. There has to be less dependency on fossil fuels. It’s no longer a question of whether we should implement more energy efficient solutions and technologies globally — it’s a question of how we are going to do that. By increasing our energy efficiency, we can reduce our dependence of Russian oil and gas completely and move closer to achieving climate neutrality. The conference in Sønderborg and the gathering of energy and climate leaders from various sectors and all parts of the world is an important step in the right direction.”

He added that Denmark was first to witness the green revolution. Because of which there are many Danish companies who are front-runners in energy efficiency solutions. “By exporting energy efficient solutions, the companies are making profits, creating jobs and helping humanity. Energy efficiency is a win-win.”

Kim Fausing, president and CEO at Danfoss, said: “If the world is to meet climate goals to limit global warming, energy efficiency measures must be prioritised. A third of the reduction needed in CO2 emissions this decade according to the IEA net zero scenario must come from improvements in energy efficiency. The good news is that the solutions are there to improve energy efficiency in all sectors. We don’t need to wait. We need action because the greenest energy is the energy we don’t use.”

During the day, leaders in industry, government and civil society discussed issues such as buildings of the future, the role of consumer behaviour, and how to unlock financing for efficiency measures.

According to the new IEA analysis, doubling the current global rate of energy intensity improvement to four per cent a year has the potential to avoid 95 exajoules a year of final energy consumption by the end of this decade compared with a pathway based on today’s policy settings. This is equivalent to the current annual energy use of China. That level of savings would reduce global CO2 emissions by an additional five billion tonnes a year by 2030, about a third of the total emissions reduction efforts needed this decade to move the world onto a pathway to net zero emissions by mid-century, as laid out in the Net Zero Roadmap the IEA published last year.

These extra efficiency efforts would cut global spending on energy. For example, households alone could save as much as $650 billion a year on energy bills by the end of the decade compared with what they would have spent in a pathway based on today’s policy settings. The amount of natural gas that the world would avoid using as a result of this would be equal to four times what the European Union imported from Russia last year, while the reduced oil consumption would be almost 30 million barrels of oil per day, about triple Russia’s average production in 2021. Compared to today, this global push on efficiency would help create 10 million additional jobs in fields ranging from building retrofits to manufacturing and transport infrastructure.

The new IEA analysis shows the significant opportunities for rapid energy efficiency gains in all sectors of the global economy. Most of these opportunities involve readily available technologies and would fully pay for themselves through lower running costs, especially at today’s high energy prices. By 2030, around a third of the avoided energy demand comes from deploying more efficient equipment, ranging from air conditioners to cars. About a fifth comes from electrification, such as switching to heat pumps or electric cars. Digitalisation and use of more efficient materials in industry provide much of the rest.
