Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system.
To improve energy security, we need to make infrastructures less reliable.
As long as we keep accumulating raw materials, the closing of the material life cycle remains an illusion, even for materials that are, in principle, recyclable.
Our new website is designed to radically reduce the energy use associated with accessing our content.
For centuries, the Netherlands were mainly dredged by hand, supplemented by animal power, wind power and tidal power. Could it be done again?
How to live a more sustainable life? By placing responsibility squarely on the individual, attention is deflected away from the many institutions involved in structuring possible courses of action.
Compressed air energy storage is a sustainable and resilient alternative to chemical batteries, with much longer life expectancy, lower life cycle costs, technical simplicity, and low maintenance.
Historical compressed air systems hold the key to the design of a low-tech, low-cost, robust, sustainable and relatively energy efficient energy storage medium.
Researchers have calculated minimum levels of energy use needed to live a decent life, but what about maximum levels?
How energy-efficient a home is depends not only on the energy label but also on the lifestyle.
To focus on energy efficiency is to make present ways of life non-negotiable.
Adjusting energy demand to supply would make switching to renewable energy much more realistic than it is today.
