Despite decades of talk about the energy transition, the fundamental reality is this: fossil fuels — coal, oil, and gas — still provide approximately 80% of the world's total primary energy. Not 80% of electricity. 80% of all energy, including heating, transport, and industrial processes.
This is not because no one has noticed the problem. It is because energy systems are enormous, expensive, and slow to change. The global electricity grid represents trillions of dollars of infrastructure built over more than a century. Replacing it takes decades, not years.
Where the Energy Comes From — and Who Controls It
Fossil fuel reserves are not evenly distributed. They are concentrated in specific geological formations that happen to be underneath particular countries. This geography of resources is the foundation of modern geopolitics:
| Resource | Where It Is | Geopolitical Significance |
|---|---|---|
| Oil | Middle East holds ~50% of known reserves (Saudi Arabia, Iran, Iraq, UAE, Kuwait). Also: Venezuela, Russia, North Sea | Middle Eastern countries have used oil as political leverage repeatedly — the 1973 oil embargo caused economic crisis across the West. OPEC (the oil exporters' cartel) can influence global prices by adjusting production. |
| Natural gas | Russia has ~17% of global reserves; also Qatar, Iran, USA, Australia | Russia uses gas pipelines as geopolitical tools — it can threaten to cut supply to countries that oppose it politically, as it did to Europe in 2022. Countries dependent on Russian gas face impossible choices. |
| Coal | USA, Russia, Australia, China, India — relatively widely distributed | Less geopolitically sensitive because of wider distribution and the ability to ship it by sea. But coal is the most carbon-intensive fossil fuel and a major driver of climate change. |
| Uranium (nuclear) | Kazakhstan, Canada, Australia, Namibia | Nuclear requires very small quantities of fuel per unit of energy, reducing import dependence. France imports uranium but uses so little that it represents minimal vulnerability. |
The Energy Transition — Why It Is Happening and Why It Is Slow
Something extraordinary has happened to the cost of renewable energy. In 1976, a solar panel cost approximately $100 per watt of power it could generate. By 2023, the cost was less than $0.20 per watt — a 99.8% cost reduction in less than 50 years. Offshore wind has become the cheapest source of new electricity generation in the UK. This is why the transition is accelerating: it is now cheaper to build new wind and solar than to run many existing coal plants.
But the transition faces real obstacles that enthusiastic advocates sometimes understate:
Quick Check: Explain what energy security means and give one example of a country that faces energy insecurity.
Energy security means having reliable access to sufficient, affordable energy to meet a country's current and future needs without excessive dependence on foreign suppliers or vulnerable supply chains. A country is energy insecure when its supply can be interrupted, its prices can spike unpredictably, or large parts of its population lack access to energy entirely. Example: Germany — before 2022, Germany imported approximately 55% of its gas from Russia. When Russia restricted supplies following its invasion of Ukraine, Germany faced energy price tripling, potential factory shutdowns, and had to scramble to build LNG import terminals and find alternative suppliers. Its heavy dependence on a single politically unreliable supplier had turned energy into a strategic vulnerability. Also accept: Nigeria — 8th largest oil producer yet 40% of population lacks electricity; UK — imports 40% of its gas.
