Energy & Environment

Fuel, efficiency, shore connection and propulsion choices read against vessel class, route and regulation.

Use this desk when the question crosses a boundary. Energy & Environment is a starting point, not a claim that one label explains the whole maritime system.

The editorial method keeps dated sources, uncertainty and reader usefulness in the same frame. The Logbook carries the questions that are still moving.

The same logic that governs a ship's energy balance applies on land. A low-energy building treats the envelope as a thermal barrier, stores heat in the ground, and ventilates through a buried air duct, so heating and cooling demand drop before any machine is sized. Owners and planners working in German can follow these principles in the Bauklima Magazin, an independent editorial magazine on energy-efficient construction and passive building climatisation. It explains wall construction, ground storage and renovation of older stock, and documents the history of solar and geothermal systems without selling equipment or acting as a manufacturer.
