Ecological economist David Stern recently wrote a paper on the importance of energy for economic growth aptly titled ‘The Role of Energy in Economic Growth’.
What was the main source of growth in Sweden in the 19th and early 20th century?
Stern and Kander (2011) show that the growth of energy use and energy augmenting technological change were the main sources of growth in Sweden in the 19 th and early 20 th century. However, in the late 20 th century labor augmenting technological change became the dominant driver of technological change. This explains the industrial revolution as a releasing of the constraints on economic growth due to the development of methods of using coal and the discovery of new fossil fuel resources.
Why does the mainstream economic growth model ignore energy?
This explains why mainstream economic growth theory ignores energy – it is mostly designed to explain the last sixty years of economic history when energy has been abundant and cheap in developed countries.
Does energy use grow faster than GDP?
However, energy use has grown much more slowly than has GDP. This means that energy intensity – energy used per dollar of GDP – has declined steadily over time. When we look at a snapshot in a given year there is also a strong relationship between per capita energy use and income per capita across countries:
Does trade reduce energy use?
Evidence also shows that trade does not result in reductions in energy use and pollution in developed countries through the off-shoring of pollution intensive industries.
Is energy necessary for economic growth?
While physics shows that energy is necessary for economic production and, therefore, economic growth, the mainstream theory of economic growth, except for specialized resource economics models, pays no attention to the role of energy. Ecological economists, on the other hand, often ascribe the central role in economic growth to energy.

What are the factors of economic growth?
From the time of Adam Smith and classical economic thought, country, labor and capital, they are considered the main factors of production and the main sources of economic growth. In time, these factors have been added by the organization as the fourth factor, while in recent times added knowledge or intellectual capital. During the development of economic thought and in economic doctrines, the direct and explicit importance of the role of energy as one of the keys to the factors of economic prosperity was not given. Energy remains present and recognized in economic theory and practice as an intermediate good while, according to still current models of neoclassical economics, economic growth is attributed to technological progress and knowledge. In economic theory, for a long time, the amount of energy available to a given economy was endogenously
What are the most important strategic documents of Serbia?
The most important strategic documents of the Republic of Serbia (Strategy for the development of enegetics by 2025 with projections until 2030 and the National Strategy for the sustainable use of natural resources and goods) undoubtedly point to the necessity of promoting greater use of renewable energy sources (but the results so far are still unsatisfactory). In the above-mentioned document, it is unambiguously stated: "All analyzes of key economic and technological changes indicate that in the last two and a half centuries, energy has been the driving force and key factor of economic change, as well as the backbone of economic development. Changes that take place globally require a long-term perspective of their impact on the national level and proper management of energy development. " According to Directive 2009/28 / EC, "energy from renewable sources is energy from non-fossil renewable sources, such as: wind energy, solar, aerothermal, geothermal, hydrothermal, ocean energy, hydropower, biomass, landfill, gas from waste treatment plant and biogas . "Renewable energy sources and their management is an important issue in all developed countries. "The priority of world development today is the protection of energy supply at affordable prices, but in order to maintain and increase living standards. At the same time, the negative effects of the use of energy on the environment, especially fossil fuels, must be reduced. Therefore, the world from year to year redefines energy policy and focuses on the creation of a competitive energy market through the use of renewable energy sources. "(Mihajlović-Milovanović, Z. 2010, page 59) A good way to point out the significance and impact energy on the economy and the environment by applying a tabular overview.
