One of the key achievements of industrial and post-industrial society has been the unlocking of concentrated energy sources that go well beyond the biopowered systems of the past - whether slaves, horses or trees. All the ills of the anthropocene are downstream from this unlocking, but it's also true that modern health and prosperity depend on the widespread availability of concentrated energy: no hospital or supermarket can work without abundant energy supplies.
Unfortunately, that energy abundance has greatly increased energy inequality, just as it has done so for other aspects of modern society.
The global distribution of energy use closely mirrors patterns of economic inequality, both among countries and within their populations. High-income nations and households consume vastly greater amounts of energy than their lower-income counterparts. The wealthiest one percent globally are responsible for about fourteen percent of the world’s energy use, and the top ten percent collectively account for nearly half of total consumption. In stark contrast, the bottom half—representing billions of people—uses only about thirteen percent of all energy.
Per capita energy consumption exposes this divide even more sharply. Residents in countries like the United States, Canada, Norway, and the Gulf states command up to a hundred times more energy per person than those in the world’s poorest countries. While reliable data for many low-income nations is limited due to their reliance on traditional, unquantified fuels such as biomass, the disparity is clear, particularly in access to commercial energy sources like grid electricity, petroleum, and natural gas. Households at the bottom of the global income spectrum average less than ten gigajoules per person each year, compared to nearly 150 gigajoules for the wealthiest.
This imbalance is deeply rooted in differences in both direct and indirect energy use. Poor households often consume energy directly in the form of wood, crop residues, or kerosene for heating and cooking, with little access to modern fuels or electricity. As incomes rise, energy consumption patterns shift: affluent populations consume more electricity, fuel for transportation, and a growing share of energy embedded in manufactured goods, infrastructure, and digital services. Indirect energy use - required in the production of food, consumer goods, information technology, and global transport - surges with affluence.
The economic gradient of energy use has consequences beyond individual well-being. Inequality in energy access translates into unequal opportunities for education, health, and productivity. Rural populations, often the poorest, lag significantly behind urban dwellers in energy access, perpetuating cycles of poverty. Meanwhile, rising incomes and rapid development in middle-income economies like China, India, and Brazil have driven the majority of global growth in energy consumption in recent decades, yet the overall picture remains one of stark and persistent inequality.
Ultimately, reducing energy poverty and decarbonizing global energy systems requires grappling with these entrenched disparities. Addressing income inequality and improving access to modern energy are deeply interconnected challenges.
