Choosing what a four-hour battery should do
The number on a storage project's nameplate tells you one relationship between power and energy. It does not tell you which grid problem the project is meant to solve.
9 min readThe energy transition is waiting for a grid
Connection queues reveal a problem with wires, operating rules and project readiness. The solutions have to address all three.

The overlooked battery is a tank of heat
When the final product is heat, storing electricity and converting it later is only one possible route. Temperature, timing and integration decide which route is useful.

Ground-source heat pumps across the seasons
A borehole connects a building to a useful thermal environment. The long-term result depends on seasonal flows, the design of the field and who is responsible for the system around it.

A city can grow its canopy and still leave people in the sun
An aerial canopy map and a walk to the bus stop describe different cities. Phoenix's shade program, and new research on how cooling is measured, show why both views matter.

The building is part of the heat warning
A weather alert stops at the front door. A desk-based walk through an imagined apartment shows why its roof, windows, ventilation and operating arrangements belong in the same heat plan.

How recycled water earns a place in the drinking supply
Orange County and Singapore show that reuse is an operating system, not a machine that makes public responsibility disappear. Follow the water and the decisions have to follow it.

A seawall buys time. Who owns the time it buys?
A protected waterfront, an adapted building and a relocated community buy different futures. The difficult question is how the benefits and obligations are shared before the next decision arrives.

Offshore wind begins on land
Port Talbot's floating-wind plans reveal the industrial system behind a turbine at sea: quays, storage, vessels, workers and a project pipeline credible enough to build for.

Community solar has to survive the subscription contract
A ten-percent discount can describe a credit rather than the whole electricity bill. Two fictional statements show why community solar's promise depends on billing, timing and the right to leave.

When the evening peak moves
Moving electricity use can reduce a difficult peak without reducing the service people receive. The opportunity depends on whose timetable can move, what it costs and how delivery is verified.

White roofs, London summers and a temperature claim
Reflective roofing changes a surface's energy balance. Turning that into a claim about a bedroom, an annual bill or a whole city requires three different assessments.

The ocean remembers heat longer than a news cycle
A cooler surface year can coexist with a record amount of heat below it. Following the measurements down through the water explains why the ocean cannot be read from one temperature headline.
