🌬️ Case Study B: Germany's Energiewende — The World's Most Ambitious Energy Transition

Location: Central Europe. Population: ~84 million. GDP per capita: ~$48,000 (2023). Germany is Europe's largest economy — heavily industrial, with a manufacturing sector that requires enormous amounts of reliable energy. Germany also has some of the world's strongest environmental politics, shaped by a powerful Green movement dating back to the 1980s.

In 2000, Germany launched the Energiewende — literally "energy turn" — the most ambitious renewable energy transition any major industrial economy had attempted. It set targets to generate 80% of electricity from renewables by 2030 and phase out both nuclear power and coal. Twenty-three years later, Germany has achieved extraordinary results, revealed uncomfortable challenges, and learned a brutal lesson about what "energy security" really means when Russia invaded Ukraine.

What the Energiewende Did

• Feed-in tariffs (FITs) — The government guaranteed a high, fixed price for any electricity generated from renewables and fed into the grid, for 20 years. This de-risked investment in wind and solar for farmers, communities, and companies. Anyone who installed a solar panel or wind turbine was guaranteed a profit. The result: a renewable energy investment boom unlike anything seen before.
• Solar explosion — Germany is not a particularly sunny country, but the FIT system made rooftop solar financially attractive regardless of weather. Approximately 2 million households and businesses installed solar panels. On sunny summer days, solar can now supply more than 50% of Germany's electricity demand.
• Wind power scale-up — Germany has approximately 30,000 onshore wind turbines — more than any other European country — and a growing offshore wind fleet in the North Sea. Wind can supply close to 100% of electricity on windy days.
• Renewables share growth — From approximately 6% of electricity in 2000 to approximately 50% by 2023. On some days in 2023, renewables provided over 100% of Germany's electricity needs (the surplus was exported to neighbouring countries).

The Challenges

Germany's Energiewende is genuinely impressive — and genuinely difficult. It has revealed the real obstacles to a high-renewables energy system that simpler narratives about the "green transition" tend to ignore:

The Russia Gas Lesson — Energy Security in a Real Crisis

In 2021, Germany imported approximately 55% of its gas from Russia, delivered through the Nord Stream pipeline. The gas was cheap and reliable — for decades, even through the Cold War, Russia had honoured its gas contracts. German business and political leaders dismissed concerns about dependence, arguing that economic interdependence would keep the relationship stable.

In February 2022, Russia invaded Ukraine. Germany immediately found itself in a catastrophic position. It could not quickly replace 55% of its gas supply. Its industrial economy ran on gas. It faced the prospect of factory shutdowns, household heating restrictions, and recession. In an emergency scramble, Germany:

• Built two floating LNG (liquefied natural gas) terminals in record time — normally LNG terminals take 5-10 years to plan and build; Germany built them in months under emergency powers
• Signed long-term LNG supply contracts with the USA and Qatar — but at prices far higher than Russian pipeline gas
• Reactivated several coal power plants that had been scheduled for closure — a humiliating reversal for a country that had positioned itself as the global leader in the green transition
• Launched an emergency programme to reduce gas consumption by 20% — industries were paid to shut down, households were urged to lower thermostats, some public buildings cut heating
• Energy prices tripled across Germany and much of Europe, contributing to a severe cost-of-living crisis

Germany survived the crisis without the rationing its officials had feared. But the experience exposed a fundamental contradiction: the Energiewende had transformed electricity generation, but Germany had remained almost entirely dependent on Russian gas for heating buildings and running heavy industry. Renewable electricity had reduced dependence in one sector; nothing had reduced dependence in others.

Exam Takeaway: Germany

The Germany lesson: Even a world leader in renewables can face energy insecurity if it is dependent on imported fossil fuels for heating and industry. Germany's Energiewende took electricity to 50% renewables but left gas dependence untouched — and that dependence became a vulnerability when Russia invaded Ukraine. Renewable energy is essential for long-term energy security, but it does not eliminate all risks.
