UN Adviser: Fossil Fuel Dependence Is a Direct Threat to Global Economic Stability
Published · 4 min read
A top United Nations climate official is warning that the world’s reliance on fossil fuels is not just a climate problem. It is a fundamental threat to economic stability, and the shift to renewable energy is now an urgent financial necessity.
Selwin Hart, the UN’s Special Adviser on Climate Action, says economies built on oil, gas, and coal are structurally vulnerable to price shocks, inflation, and financial crises that no government policy can fully prevent.
A Crisis That Exposed the Fault Lines
The 2022 energy shock triggered by Russia’s invasion of Ukraine made the risks impossible to ignore. Fossil fuel prices surged across global markets, and the fallout was severe.
70 million people were pushed into poverty as a direct result of that single geopolitical event. Developing nations were forced to drain foreign exchange reserves, cut public spending, or watch their currencies collapse.
This was not an isolated event. It was the predictable outcome of a system built on commodities controlled by a small number of producers and moved through a handful of critical chokepoints.
Approximately one-third of globally traded oil passes through the Strait of Hormuz alone. Any disruption there, whether from conflict, politics, or disaster, sends shockwaves through every economy that depends on imported energy.
Who Bears the Heaviest Burden
The exposure is vast. Roughly 80 percent of the global population, around 6 billion people, lives in countries that are net importers of fossil fuels.
For wealthier nations, price spikes mean higher inflation and tighter monetary policy. For poorer ones, the consequences are far more severe. Countries including Sri Lanka, Pakistan, and several sub-Saharan African nations faced near-default on sovereign debt during the 2022 crisis, driven largely by fossil fuel import costs.
The European Central Bank has formally recognized fossil fuel dependence as a macroeconomic risk, not just an environmental concern. When energy prices spike, inflation follows. Central banks must then choose between raising interest rates to control prices or keeping them low to protect growth. Neither option fully works when the shock comes from outside the domestic economy.
Renewables Are Now the Cheaper Option
The economic argument for staying with fossil fuels has weakened significantly. Solar energy is now 41 percent cheaper than fossil fuel alternatives. Offshore wind is 53 percent cheaper.
More than 90 percent of new renewable energy projects are now less expensive than building new fossil fuel capacity. These are not subsidy-driven figures. They reflect real technological progress and manufacturing scale.
Between 2015 and 2024, global renewable electricity capacity grew by approximately 2,600 gigawatts, a 140 percent increase. In 2025, wind and solar farms generated more electricity than coal plants globally for the first time in history.
Renewables now account for 49 percent of global installed power capacity and 85.6 percent of all new capacity added in 2025.
The Job and Growth Case
Clean energy is also generating employment at a faster rate than fossil fuels. For every dollar invested in renewables, three times as many jobs are created compared to fossil fuel investment.
The International Energy Agency estimates that while around 5 million fossil fuel jobs could be lost by 2030, roughly 14 million new clean energy jobs would be created, a net gain of 9 million positions.
In the United States alone, clean energy employment grew by 142,000 jobs in 2023, at a rate more than twice the overall pace of economic growth that year.
Clean energy sectors drove 10 percent of global GDP growth in 2023. Global investment in energy transition reached a record $2.3 trillion in 2024, outpacing fossil fuel investment by $800 billion.
Stability That Fossil Fuels Cannot Offer
Hart’s core argument is structural. Renewable energy offers something fossil fuels fundamentally cannot: stability, sovereignty, and control.
Wind and sunlight cannot be embargoed. They are not subject to geopolitical pricing or supply disruptions rooted in distant conflicts. Once solar panels and wind turbines are installed, they generate power for decades without exposure to commodity markets.
Countries that build their energy systems around renewables regain control of their monetary and fiscal policy. Inflation driven by external energy shocks becomes far less likely. Currencies stabilize. Governments can redirect resources away from managing energy crises and toward education, health, and infrastructure.
The International Renewable Energy Agency projects that 90 percent of the world’s electricity can and should come from renewable sources by 2050. Several countries, including Denmark, Portugal, Costa Rica, and Iceland, are already close to or at that level.
What Comes Next
The UN Secretary-General has called for a global platform for dialogue on transitioning away from fossil fuels, bringing together governments, industry, finance, and civil society to coordinate policy and investment at scale.
The transition still requires major investment. Achieving net-zero emissions by 2050 would require roughly $9.2 trillion in annual spending on physical assets, around $3.5 trillion more than today. A significant share of that gap falls on developing countries that lack access to affordable capital.
Hart and the UN are pressing developed nations to provide concessional financing and debt relief to help close that gap, arguing that without it, the most vulnerable economies remain trapped in a system that repeatedly punishes them for circumstances beyond their control.
The direction of global capital is already shifting. The question, according to the UN, is whether it shifts fast enough.
