The energy that's coming: China's wind power records, Europe's new battery chemistry, and Spain's solar challenge

The world of energy is moving faster than most people realise. And I'm not talking about promises or dinner-table debates. I'm talking about real numbers, factories running flat out, and a race where China has just left even its toughest rivals gobsmacked.

In 2025, Beijing installed more new wind capacity than the United States has built in its entire history. Yes, you read that right. An energy unit so colossal it rewrites the rules of the game. While wind turbines are sprouting like mushrooms over there, here in Europe we're focusing on another critical piece: the chemistry behind electric car batteries. Because generating renewable energy is pointless if we can't store it efficiently.

The quiet wind miracle and what Spain can learn from it

What's happening in China isn't luck. They've been investing like crazy for years, but 2025 was a quantum leap. No one saw that level of intensity coming. And look, I'm not saying everything's perfect: China's massive renewables push also comes with local tensions, debt, and increasingly tense geopolitics. But in terms of pure installed capacity, the gap is now a chasm.

And Spain? We've got something they'd envy: the sun. Solar energy is enjoying a second youth, but we're still dragging our feet with grid issues, red tape, and planning that sometimes feels stuck in the '90s. Still, there's reason for optimism. More homes and industries are going for self-consumption, and panel prices keep falling.

• China dominates onshore and offshore wind: it topped 400 GW of cumulative capacity in 2025.
• Europe is betting on new battery chemistry (lithium-sulphur, solid-state) to avoid relying on Asia.
• Spain has the highest solar potential in the EU, but urgently needs distribution grid reforms.

The battery battle: Europe refuses to be left behind

While Beijing grabs headlines with its turbines, German and French labs are writing another key chapter. The next generation of electric car batteries will look nothing like today's. We're talking cells with higher energy density, less cobalt, and a lifespan that could double what we have now. Several European manufacturers already have prototypes running in real-world conditions. The goal: by 2028, an energy unit stored in Barcelona or Stuttgart can compete on price and performance with the best from China.

And why does this matter? Because renewable energy is intermittent. Without large-scale storage, we'll keep burning gas on windless, sunless days. Battery chemistry, at its core, is the key that will finally lock the door on fossil fuels.

The reality behind the Asian giant – and our opportunity

Not everything is golden in the wind empire. China's massive renewables investments also displace communities, create local environmental impacts, and follow a power logic that scares Brussels. But denying their achievements would be as blind as it is ridiculous. What they've done in wind capacity in a single year would take Europe a decade to match.

So here we are, at a fascinating crossroads: on one side, the necessary partner (China) selling us cheap panels and turbines; on the other, the urgent need to develop our own tech (batteries, smart grids) so we're not dependent forever. And in the middle, Spain, with its endless hours of sun and a wind industry that can still fight back.

The energy of the future won't be a single colour or a single country. It'll be a mix of Chinese wind, European chemistry, and Spanish sun – as long as we get our act together. Because records are great, but what really matters is that when you flip the switch five years from now, that electricity is cleaner, cheaper, and more our own.
