A state that cannot fuel itself cannot really choose its foreign policy. That old truth is why every serious government treats energy as a national-security file, not an environment file. The 2022 gas crisis in Europe, the 1973 oil embargo, the 2021 Chinese coal shortage, the 2000 California blackouts — the same lesson each time. Independence does not have to mean autarky; it means having enough diversification, enough storage and enough alternatives that no single supplier or single chokepoint can force your hand. The green transition is not separate from that logic. It is the newest chapter of it.
Between 2008 and 2019, hydraulic fracturing turned the US from the world's largest oil importer into the world's largest oil and gas producer. That single geological and technological accident is one of the most under-reported strategic shifts of the century. It made the US energy-independent in net terms, gave it LNG cargoes to sell to a panicked Europe after 2022, weakened OPEC's pricing power, and gave Washington the freedom to sanction Russian and Iranian oil without wrecking its own economy. Every US foreign-policy option since Obama — pivot to Asia, sanctions on Russia, tariff wars with China — is easier because the US no longer needs to ask permission at a Saudi filling station.
Russia earns most of its foreign currency from hydrocarbons, and until 2022 its most reliable, best-paying customer was Europe — pipelines running west, prices in euros, contracts in decades. The invasion of Ukraine, the sabotage of Nord Stream and the European scramble to replace Russian gas ended that arrangement. Moscow has redirected barrels to India and China at deep discounts, but the pipelines run the wrong way for that pivot: Power of Siberia 2, the planned mega-pipeline to China, is still not built, and Beijing knows it has all the leverage in the price negotiation. A petro-state without a captive premium market is a much weaker petro-state.
Before 2022 Europe got roughly 40% of its natural gas from Russia; Germany was above 55%. By 2024 Russian pipeline gas into the EU had collapsed to under 10%, replaced by a scramble of Norwegian pipeline gas, US and Qatari LNG cargoes, aggressive energy saving, a temporary return to coal, and a big acceleration of wind and solar. It worked — the lights stayed on — but it cost European households and industry dearly and left Europe with the highest industrial electricity prices among major economies. The German chemical and steel industries have not fully recovered. Cheap Russian gas turned out to have been a hidden subsidy to European manufacturing, and losing it is one of the reasons Europe now looks less competitive against both the US and China.
China is simultaneously the world's largest coal consumer, the world's largest oil importer, and by a wide margin the world's largest builder of renewables. In 2024 alone China installed more solar capacity than the entire existing US solar fleet. It dominates the manufacturing of solar panels (around 80% of global capacity), lithium batteries (roughly 75%), wind turbines and EVs. The strategy is not idealism — it is security. Every kilowatt-hour generated from a Chinese-built panel on Chinese soil is a kilowatt-hour that does not have to cross the Strait of Malacca in an oil tanker that the US Navy could sink. Green energy, from Beijing's point of view, is the most patriotic energy there is.
Saudi Arabia, the UAE and Qatar know that peak oil demand is a matter of when, not if. Their response is not to deny it but to prepare for it: Vision 2030, NEOM, sovereign wealth funds buying stakes in every technology worth owning, huge investments in solar and hydrogen (the Gulf has some of the world's best solar irradiance), and — as covered in the AI race module — a bet on being the world's low-cost providers of AI compute. The strategic argument is subtle: the more the world electrifies, the more valuable cheap, sunny, politically stable desert becomes. The Gulf is trying to convert an oil rent into a compute rent before the oil rent runs out.
France produces around 70% of its electricity from nuclear power — the highest share of any major economy — and exports electricity to most of its neighbours. That is the result of a deliberate 1970s decision after the oil shocks: never again be blackmailed by an oil producer. Fifty years later, as Germany shuts down its last reactors and imports gas, France's grid is one of the cleanest and most secure in Europe. Nuclear is now quietly making a comeback across the world (UK, Poland, Sweden, Netherlands, South Korea, and the small-modular-reactor bets in the US) precisely because it solves the one problem wind and solar do not: baseload, on-demand power. For AI data centres and heavy industry, that matters enormously.
Here is the uncomfortable twist. A country that swaps imported oil for imported solar panels, imported batteries and imported rare earths is not more independent — it has just changed suppliers. If those panels, batteries and refined minerals all come from China, the green transition can quietly rebuild the same dependency it was supposed to end. That is the anxiety behind the US Inflation Reduction Act, the EU Critical Raw Materials Act and the Net Zero Industry Act: not opposition to green energy, but insistence that the supply chain be domestic or allied. Energy independence in the twenty-first century is not just about barrels of oil; it is about who owns the mine, who owns the refinery, and who owns the factory.
The energy-independence league table of the twenty-first century looks like this. Fully independent in fossil fuels: the US, Canada, Norway, Australia, the Gulf, Russia. Fully independent in clean-tech manufacturing: China, alone. Independent in nuclear: France, South Korea, and a growing club. Dependent on almost everything: most of Europe, Japan, India and Africa. The green transition is the biggest chance in a century to reshuffle that table — but only for the countries that treat it as an industrial-policy war, not as an environmental-policy debate.
