The global historical series for primary energy consumption (PEC) and Gross Domestic Product (GDP) spanning the last two centuries has recently become available. In this study, authors Herve Bercegol and Henri Benisty propose a new macroeconomic model that suggests physical power is fueling economic power. The data analysis reveals that from 1820 to 1920, there was linearity between global PEC and world GDP, which justifies basic equations where PEC incorporates unskilled human labor that consumes and converts energy from food. In a consistent model, both physical capital and human capital are fed by PEC and represent a form of stored energy. In the following century, from 1920 to 2016, GDP grows quicker than PEC. Periods of quasi-linearity of the two variables are separated by distinct jumps, which can be interpreted as radical technology shifts. The GDP to PEC ratio accumulates game-changing innovation at an average growth rate proportional to PEC. These results seed alternative strategies for modeling and political management of the climate crisis and the energy transition. The authors' findings suggest that physical power is essential in driving economic growth across different periods in history. Additionally, their proposed macroeconomic model provides insights into how stored energy in physical capital and human capital contributes to economic development. This study's results could inform policymakers on alternative strategies for managing the climate crisis while promoting sustainable economic growth through efficient use of primary energy consumption.
A new way of understanding how energy and money are connected has been discovered. For a long time, when people used more energy, the economy grew at the same rate. But now, even though we use more energy than ever before, the economy is growing faster than the amount of energy we use. This is because we have found new ways to use technology to make things more efficient. Using less energy can help us take care of the environment while still making our economy grow.

- Macroeconomic model: a way of understanding how different parts of an economy work together
- Physical power: the energy that comes from things like oil, gas, and coal
- GDP: Gross Domestic Product - a measure of how much money an entire country makes in a year
- Primary energy consumption (PEC): how much physical power is being used by a country or the world as a whole
- Physical capital: things like buildings and machines that are used to make products or provide services
- Human capital: the skills and knowledge that people have that allow them to do their jobs well
- Game-changing innovation: new ideas or inventions that completely change how something is done
The Impact of Physical Power on Economic Growth: A Macroeconomic Model
In a recent study, authors Herve Bercegol and Henri Benisty propose a new macroeconomic model that suggests physical power is fueling economic power. Using global historical series for primary energy consumption (PEC) and Gross Domestic Product (GDP), the authors analyze data spanning two centuries to explore how stored energy in physical capital and human capital contributes to economic development. Their findings provide insights into alternative strategies for managing the climate crisis while promoting sustainable economic growth through efficient use of primary energy consumption.
Data Analysis Reveals Linearity Between Global PEC and World GDP
The data analysis reveals that from 1820 to 1920, there was linearity between global PEC and world GDP. This finding justifies basic equations where PEC incorporates unskilled human labor that consumes and converts energy from food. In this consistent model, both physical capital and human capital are fed by PEC, representing a form of stored energy.
Quasi-Linearity Separated by Jumps Interpreted as Technology Shifts
From 1920 to 2016, GDP grew quicker than PEC. Periods of quasi-linearity between the two variables were separated by distinct jumps which can be interpreted as radical technology shifts. The GDP to PEC ratio accumulates game-changing innovation at an average growth rate proportional to PEC.
Implications for Climate Crisis Management Strategies
These results seed alternative strategies for modeling and political management of the climate crisis and the energy transition based on understanding how physical power is essential in driving economic growth across different periods in history. By recognizing how stored energy in physical capital and human capital contributes to economic development, policymakers can develop more effective strategies for managing the climate crisis while promoting sustainable economic growth through efficient use of primary energy consumption.
Global historical series spanning the last two centuries recently became available for primary energy consumption (PEC) and Gross Domestic Product (GDP). Based on a thorough analysis of the data, we propose a new, simple macroeconomic model whereby physical power is fueling economic power. From 1820 to 1920, the linearity between global PEC and world GDP justifies basic equations where, originally, PEC incorporates unskilled human labor that consumes and converts energy from food. In a consistent model, both physical capital and human capital are fed by PEC and represent a form of stored energy. In the following century, from 1920 to 2016, GDP grows quicker than PEC. Periods of quasi-linearity of the two variables are separated by distinct jumps, which can be interpreted as radical technology shifts. The GDP to PEC ratio accumulates game-changing innovation, at an average growth rate proportional to PEC. These results seed alternative strategies for modeling and for political management of the climate crisis and the energy transition.
