20 Most Efficient Countries in the World

In this article, we will discuss the 20 most energy-efficient countries in the world. You can skip our detailed analysis of the most efficient countries and go directly to the 5 Most Efficient Countries in the World.

Energy efficiency is one of the most beneficial practices in current times. It helps deal with the growing energy demands while also mitigating climate change. This significant phenomenon has immense potential. It could enable countries to reduce GHG emissions and bring them closer to achieving SDG 7. Energy efficient policy actions also help save the citizens’ money, create new jobs, and reduce pollution. According to a report by IEA, Energy-efficient policies could create an extra ten million jobs by 2030. The IEA’s World Energy Outlook 2022 claims that a 13% reduction in annual carbon emissions would significantly reduce the impact of climate change. 

The rising attention towards energy efficiency globally has led to the growth of the energy efficiency industry. Global investments in efficient energy are at an all-time high. The pandemic and the Russian-Ukraine war have catalyzed this process; governments worldwide are now prioritizing efficient, sustainable, and reliable energy sources. According to IEA, since 2022, $1 trillion has been spent on energy efficiency globally. The IEA has forecasted this spending to reach $2.8 trillion in 2023. It also mentions that 90% of the entire investment in electricity generation would be concentrated on low-emission power.

Why energy efficiency?

Global energy demand is increasing rapidly. Meeting this demand using our current energy practices would be unsustainable. According to the Sixth Assessment report by the IPCC, our planet will hit almost 1.5 degrees Celsius of warming without considerable intervention to control GHG emissions in the next 20 years. The ACEEE report pointed out that energy efficiency can help achieve 50% of the GHG emission reduction goal set by the Paris Agreement. This practice also increases grid reliability while providing resilience in extreme weather conditions. Energy fuels all sectors of the economy and enables economic growth. More energy efficiency, therefore, entails more efficient economic growth. It creates more jobs, while controlled pollution rates improve the health of the citizens. The pandemic seriously affected and slowed down its progress. According to IEA’s Energy Efficiency 2022 report, the annual gains for the international energy intensity progress dropped to almost 0.5% in 2020 and 2021. It is an inevitable benchmark for achieving a net zero scenario in the future. 

The energy efficiency measure holds immense value. According to estimates by IEA, it can help avoid 5 gigatonnes of CO2 emissions per year by 2030. These practices would also have a positive spillover into other sectors of the economy. The governments adopting these policies are conscious of these positive implications. Achieving it is a process that requires profound changes in both policy and practice. Some of the world’s largest energy consuming countries are getting more energy efficient. There has been an increase in investment in renewables. According to a June 2023 report by the World Economic Forum, in 2022, investments in renewables reached $1.3 trillion, almost a 70% increase from pre-pandemic levels in 2019.

Alternative Energy Sources

Fossil fuels still dominate the global energy supply. The high energy density of fossil fuels has contributed to this persistent position. However, options like nuclear fusion could help reduce this share. According to the IAEA, nuclear fusion is four million times more dense than fossil fuels. According to the Culham Centre for Fusion Energy, one kilogram of fusion fuel provides the same energy as 10 million kilograms of fossil fuel.

Nuclear fusion also does not emit any greenhouse gasses and many of the most developed countries are now focusing on nuclear fusion. According to the European Commission, the E.U. contributes 45% to the ITER (International Thermonuclear Experimental Reactor) project. It is an engineering megaproject aiming to generate fusion energy. It has allocated EUR 5.61 billion to the project from 2021 to 2027.

Major Companies That are Working on Energy Efficiency

Let’s take a look at some notable companies that are working on energy efficiency. Siemens Aktiengesellschaft (OTC:SIEGY) is one of the most prominent companies in this regard. Siemens Aktiengesellschaft (OTC:SIEGY) is a leading provider of energy efficiency solutions, offering a wide range of products and services including wind turbines, solar panels, and energy-efficient building technologies. The company reportedly grew its revenue by 14% in the second quarter of 2023 and generated EUR 19.4 billion on a nominal basis. The company’s net income rose to EUR 3.6 billion.

Honeywell International Inc. (NASDAQ:HON), a leading developer of energy technologies, is also a noteworthy name when we talk about energy efficiency. In the first quarter of 2023, the company reported earnings per share of $2.07 and outperformed EPS estimates by $0.14. The company’s revenue for the quarter amounted to $8.86 billion, up 5.83% year over year and ahead of Wall Street estimates by $349.90 million.

Johnson Controls International (NYSE:JCI) and Schneider Electric (OTC:SBGSY) are also important contributors to the energy efficiency industry. As of July 20, Johnson Controls International (NYSE:JCI) has surged more than 35% and Schneider Electric (OTC:SBGSY) has gained roughly 40%, over the past 12 months.

Our Methodology

We have only considered the world’s top energy-consuming countries for this analysis. We have calculated their average ranking based on their energy efficiency scores, energy efficiency in the industrial sector, and the energy transition index, from the World Economic Forum.

We have used the ACEEE report that evaluates these top energy-consuming countries across 36 different policy and performance metrics to obtain a combined score for each. The score has been marked out 100.

Incorporating the industrial sector was significant as it accounts for almost half the total energy consumed globally. The industry score includes indicators like the energy intensity of the industrial sector, mandatory energy audits, investment in manufacturing R&D, etc. It has been scored out of 25. It is based on 10 different metrics relating to both policy and performance.

We have also included the total final energy consumption for each country, sourced from the ACEEE report. The ETI is based on energy equity, sustainability, and security. It provides a measure of transition readiness and their current energy system performance.

After compiling this comprehensive dataset of metrics, we calculated each country’s Insider Monkey score that was based on the average of the three scores we pointed out and ranked them in ascending order of this metric.
