Solar-plus-storage: why batteries now follow every panel
Solar is now the cheapest electricity on Earth, yet it only generates in daylight. The wave of giant batteries paired with every new solar farm tells a quiet story: the challenge is no longer producing energy, but shifting it through time.

Water stress and scarcity
Our planet is blue, and yet nearly 4 billion people run short of water every year. How does a seemingly infinite resource turn scarce? From India's aquifers to the Nile dam, this Fundamental decodes the mechanics of water scarcity.

International migration: flows, causes and impact
The countries tightening immigration rules the most are often those facing the sharpest labour shortages. This paradox is no accident: it reveals the structural tension between economics, demographics, and sovereignty that migration has exposed for thirty years.

China makes 80% of solar panels, and loses billions
China is breaking solar export records in the wake of the Gulf conflict. Its manufacturers are deep in the red. The paradox of an industry undone by its own success.

Climate change: science, data and projections
The science is settled. The projections, however, are not, they span a wide range of scenarios depending on choices made in the next few decades. What the IPCC actually says, what SSP and RCP scenarios mean in practice, and where the real uncertainties lie.

The energy transition: technologies, stakes, timelines
Renewables are now the cheapest source of new electricity in most of the world. Yet fossil fuels still account for over 80% of global energy consumption. Understanding why the gap exists, and what it takes to close it, is the real foundation of the energy transition.
