Why So Many Big Cities Are Running Out of Water — and Why Fixing Leaks Beats Building Dams
Half of the world's 100 largest cities draw from catchments under high or extreme water stress. Satellite data shows 1.1 billion people in drying urban regions. The gap between supply and demand is mostly in pipes, aquifers and reuse — not rainfall.
Why Copper Hit Record Prices While the Market Is in Surplus — the Midstream Squeeze Explained
LME copper set a record near $14,875 a tonne in September 2026 while the refined market ran a surplus. The squeeze is midstream — zero smelter fees, a sulphuric acid crunch and export bans. What it means for grids, EVs and data centres.
Why Undersea Cables Became Critical Infrastructure — and the Repair-Ship Bottleneck
Subsea cables carry almost all intercontinental data, yet roughly 60 ships repair the ~200 faults that break them each year. The economics, the geopolitics and the ageing fleet behind the internet's weakest link.
Why Geothermal Is Finally Scaling — and What It Means for the Grid
Enhanced geothermal borrows oil-field drilling to manufacture heat reservoirs almost anywhere. Fervo's falling well costs, Utah FORGE's test results and the seismicity risk that still caps the industry.
Why Some Houses Survive a Wildfire and Others Don't — the Science of Home Hardening
Embers, not flames, destroy most homes in a wildfire. The evidence from the 2018 Camp Fire and the 2025 Los Angeles fires shows which construction and landscaping choices actually change the odds.
Why the EU's Carbon Border Tax Is Quietly Rewriting Global Trade — and What It Means for Exporters
The EU Carbon Border Adjustment Mechanism entered its paying phase on 1 January 2026. Here is how the charge works, who really pays, and why the slow phase-in hides a much larger cost by 2034.
Why Energy Efficiency Is Still the Cheapest Power Plant We Keep Failing to Build — Analysis
Energy efficiency is the kilowatt-hour you never generate: how ACEEE and IEA data show saved energy costs a fraction of new generation, and why the world keeps underbuilding its cheapest power plant.
EV Battery Degradation Explained: What Actually Kills Capacity
EV battery degradation explained: what the fleet data says about capacity fade, which habits hurt most, and the charging routine that preserves range.
Time-of-Use Electricity Rates: How They Work and Who Saves
Time-of-use electricity rates explained: why peak hours cost more, how the duck curve sets prices, and the practical moves that cut a TOU bill.
What Is a Virtual Power Plant? The Grid Idea Explained
Virtual power plants explained: how thousands of home batteries, EVs and thermostats act as one power plant, and why the DOE wants 80-160 GW of them by 2030.
Why Decarbonizing Shipping Might Be the Hardest Net-Zero Problem — Analysis
An explainer on why maritime shipping is one of the toughest sectors to decarbonize: the IMO Net-Zero Framework agreed in 2025, the green-methanol-vs-ammonia fuel race, and what it means for freight costs.
