The study found that using more energy has less health and well -being benefits for wealthy nations.

High Response: Standard numbers by country averaged between nine metrics for each country and the high envelope entered into them. Inset: Mean, range, and quantiles by combining the nine envelope functions in Figure 1. The two paths compare the energy thresholds of each of 74 and 58 GJ, where it can be seen. 95% of high performance. Middle Answer: Energy intensity is not necessary, the difference between the perceived and the minimum energy use for each person is necessary to obtain a given metric value. Bottom line: Lack of production, direct distance below what can be used for energy per person and the real value of the land. aie: Europe (2022). DOI: 10.1002 / ecs2.3978

Longevity is essential to energy: to light hospitals, homes and schools, to be able to work, cook food and study without having to smoke poisonous or waste energy. full day of wood gathering. But sometimes, energy is limited for good.

New research from Stanford University shows that number – the threshold beyond energy use is losing its link to government -level improvements in health, economic and social standards. environment – a low level.

The results, published April 12 at Europe, believes that nations with high individual energy consumption, such as the United States and Canada, can reduce consumption without maintaining or improving well -being. Countries where energy poverty persists is difficult, as it can improve the health and well -being of the nation with less energy than experts think.

The authors today have an average global energy consumption of 79 gigajoules per person, in essence, everyone on Earth can approach a “high level of health, happiness and the quality of life of the best countries today, “if shared equally.

Looking for the goal

The other students sought for ten years to reduce the amount of energy needed for a healthy life. Initial estimates were estimated at 10 to 65 gigajoules per person. “It’s one thing to know where people don’t have enough energy; it’s another thing to know what our goal is,” said lead author Rob Jackson, a professor of geospatial science. and Stanford’s School of Earth, Energy & Environmental Sciences (Stanford). Earth). “How much new energy needs to be supplied?”

The answer to this question is not just an educational process. It is important to document how the world can achieve global goals while building new energy services for the 1.2 billion people who live without electricity and 2.7 billion who cook on stoves account for the first 3.5 million deaths each year from indoor pollution.

“We need to balance energy use and green gas emissions. Among the few ways we can do that is to raise the levels of energy consumption. we’re in the United States, ”said Jackson, who is Michelle and Kevin Douglas Provostial Professor at Stanford and a senior fellow at the Stanford Woods Office for the Environment and at the Precourt Institute for Energy. “While the use of new materials is likely to have a significant impact on the environment,” according to the resources, land and resources required to supply hundreds of gigajoules each year for each year. 8.5 billion people are expected to live on Earth by 2030.

Reducing the world’s population will reduce the amount of energy and economic resources, Jackson said. But there are other ways to replace the global energy system with less emissions. The new research provides a measure for measuring some of the human impact of one of them: reducing energy use per capita in what Jackson calls “energy profligate countries,” while increasing the rest of the world’s energy supply to similar levels.

High performance

Additional results are available from statistical data on energy use data for 140 countries from 1971 to 2018, as well as global data for nine metrics related to human health. Most of these measures are in line with the United Nations ’Sustainable Development Goals, a set of goals intended to end diversity taking into account climate problems.

The researchers looked at primary energy supply, which includes all energy -efficient emissions -reduced emissions, oceans and aircraft, as well as changes in the amount of energy. stored fuel, for each of the 140 countries. They then separate the amount of energy to increase efficiency from the energy that is consumed and used for other purposes, such as trade. .

Recognizing that efficiency is limited by many factors, including income and GDP, the authors examined whether per capita energy use could be reduced in some countries while maintaining low energy consumption. the quality of life.

Most of the metrics, including life expectancy, infant mortality, happiness, food supply, access to basic cleaning services and access to electricity, found that record performance improvement, and then increase annual energy consumption to between 10 and 75 gigajoules per person. That’s less than the 2018 world average of 79 gigajoules per person, and, at the highest end of the range, about a quarter of the U.S. average of 284 gigajoules per person.

U.S. energy use has fallen slightly per capita since the late 1970s, due to improvements in energy efficiency, but is rising slightly due to rising energy demands. Land to energy for transport.

“In most countries with more energy than the world average, increasing energy use per capita will only improve human well -being. , “said author Chenghao Wang, a postdoctoral specialist in Jackson’s lab and a research fellow at the Stanford Center .for Long.

Return the extra

The new study shows that in about 10 countries are pounding on their weight, with much better energy than most other countries that use more energy in that region. this captain. The top players are Albania, Bangladesh, Cuba, Denmark, Finland, Iceland, Malta, Morocco, Norway and Sri Lanka.

Air quality is independent of other measurements reviewed by the authors, although in 133 countries, improvements have continued with the use of energy per unit amounting to 125 gigajoules. This is similar to annual energy consumption for Denmark in 2018, and higher than China. One reason may be that fossil fuels have historically been dominated by fossil fuels.

In the United States, energy use increased dramatically after World War II – years before federally imposed limits on pollution from tailpipes and smokestacks that improved the quality of life. the air of the land. “Rich countries like the United States clean up their air only after they have built up property and the public demands work,” Jackson said.

Past research has shown that high income “does not necessarily lead to better and happier lives,” said historian Anders Ahlström, a scientist at Lund University who created to research as a postdoctoral specialist at Jackson’s lab at Stanford. “Getting energy is like making money that way: Getting more energy is the return.”


Countries that invest in renewable energy enjoy higher economic growth and lower unemployment.
