Germany's wind and solar milestone: what it means for Australia's energy transition

Something quietly historic has happened in Europe's largest industrial economy. For the first time ever, wind and solar power have generated more electricity in Germany than all fossil fuels combined. It is the kind of statistical crossover that will barely register in a news cycle dominated by wars and elections, but it marks a turning point that energy historians will circle for decades.

For Australians watching our own bumpy transition — with rooftop solar booming, coal plants closing, and the politics of gas as fraught as ever — Germany's milestone offers something more useful than a headline. It offers a live case study of what happens when a major industrial nation actually pushes through the messy middle of decarbonisation.

The milestone in context

According to analysis published by Carbon Brief, wind and solar have overtaken fossil fuels in Germany's power mix for the first time. Yale's Environment 360 and Euronews framed the moment as the practical arrival of Germany's long-promised Energiewende — the "energy turnaround" that was declared as a policy ambition more than two decades ago.

That word — Energiewende — matters. Germany didn't stumble into this crossover. It legislated it, subsidised it, argued about it, and paid for it, often at eye-watering cost to consumers. When the country began pouring feed-in tariffs into solar in the early 2000s, panels were expensive and Germany is, notoriously, not sunny. Critics called it a monumental waste of money. What those critics missed was that Germany's early demand helped drag the global cost curve for solar photovoltaics down by more than 90 per cent. Every rooftop panel now going up in Brisbane or Bendigo is, in a small way, subsidised by a German taxpayer from 2008.

Why the crossover is bigger than the numbers

A single year's generation figures can be noisy. Weather patterns, gas prices, and the pace of nuclear or coal retirements can all tilt the mix in any given quarter. What makes Germany's milestone significant is not the exact percentage point, but the direction and the durability.

As IntelliNews noted in its coverage, the shift is happening against a backdrop of considerable economic strain: high industrial energy costs, the shock of losing cheap Russian pipeline gas after 2022, and a decision to complete the phase-out of nuclear power. Any one of those pressures could have derailed the renewables build-out. Instead, wind and solar kept climbing while fossil generation — coal in particular — kept falling.

Three broader signals stand out:

The lessons Australia should actually take

Australia and Germany are not twins. We have vastly more sun, more land per capita, a smaller manufacturing base, and no neighbouring interconnected grid to lean on. But the political and engineering challenges rhyme, and Germany's experience yields at least four lessons worth taking seriously.

1. Consistency beats ambition

Germany's transition has survived multiple changes of government, from Merkel's grand coalitions to the current three-party arrangement. Policy details shifted; the direction did not. Australia's renewables rollout, by contrast, has been repeatedly whiplashed — carbon prices introduced and repealed, targets set and scrapped, capacity investment schemes stalled by political fights. The German experience suggests that mediocre policy sustained for twenty years beats brilliant policy that lasts one electoral cycle.

2. Transmission is the hard part

Germany's biggest current headache is getting power from windy Schleswig-Holstein to industrial Bavaria. Australia faces the same problem in a different geography: getting power from renewable energy zones in western NSW, north Queensland, and South Australia to the coastal load centres. Projects like HumeLink and VNI West have already run into fierce local opposition. Germany's experience is a warning that pylon politics can slow a transition even after the generation economics have been won.

3. Industry needs a plan, not just a promise

Part of what has kept Germany's transition politically viable is that heavy industry — steel, chemicals, cars — has been brought inside the tent, with hydrogen strategies, industrial electricity subsidies, and long-term contracts. Australia has an even bigger stake here, given our export exposure to iron ore, LNG, and aluminium. If we want green iron and green aluminium to be the next chapter, the German model shows that industrial policy has to move in lockstep with power sector reform.

4. Households carry the politics

Germans grumble about their electricity bills, which are among the highest in Europe. But rooftop solar, community wind co-operatives, and a broad sense of ownership have kept public support for the Energiewende remarkably resilient. Australia has, almost by accident, built something similar: more than a third of freestanding homes now have rooftop solar, giving millions of households a direct financial stake in the transition. That is a political asset governments should nurture, not squander.

What the milestone doesn't prove

It is worth being honest about the limits of Germany's moment. Overtaking fossil fuels in electricity generation is not the same as decarbonising the whole economy. Heating, transport, and heavy industry still run largely on gas, oil, and coke. Germany's total emissions are falling, but not fast enough to meet its own 2030 targets, and the closure of nuclear plants means coal has been called on more often than climate campaigners would like.

The same caveat applies to Australia. Even as renewables push past 40 per cent of the National Electricity Market on average, our transport fleet is still overwhelmingly petrol and diesel, our gas network is enormous, and our export emissions — the coal and LNG we ship overseas — dwarf our domestic footprint. A wind-and-solar-majority grid is a necessary condition for decarbonisation. It is not a sufficient one.

The signal in the noise

Still, thresholds matter, if only because they change what feels possible. For years, the argument against ambitious renewable targets in Australia has leaned on a version of "no serious industrial economy has done it." Germany has now, in the electricity sector at least, made that line harder to hold. A country with less sun than Tasmania, more industry than we have, and a decade of energy-security shocks is now generating more of its power from wind and solar than from coal and gas combined.

If the Energiewende has a lesson for Australia, it is not that the transition is easy — Germany's has been anything but. It is that the transition is possible, that it takes longer than optimists promise and costs more than sceptics expect, and that the countries which start early end up with cheaper power, cleaner air, and a seat at the table in the industries of the next century. That is a milestone worth paying attention to, even from the other side of the world.
