Why water must be at the heart of climate action

The Mortenson Center in Global Engineering & Resilience at the University of Colorado Boulder along with Castalia Advisors were commissioned by WaterAid's Resilient Water Accelerator (RWA), the Voluntary Carbon Market Integrity ...

Using light to produce medication and plastics more efficiently

Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions—but not so with photochemistry, where light provides the energy. The process to achieve the desired ...

Faster charging with diamonds

Diamond is known for its outstanding thermal conductivity. This makes the material ideal for cooling electronic components with high power densities, such as those used in processors, semiconductor lasers or electric vehicles.

Physicists develop new solar cell design for better efficiency

Physicists at Paderborn University have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, ...

Efficient energy use

Efficient energy use, sometimes simply called energy efficiency, is using less energy to provide the same level of energy service. An example would be insulating a home to use less heating and cooling energy to achieve the same temperature. Another example would be installing fluorescent lights and/or skylights instead of incandescent lights to attain the same level of illumination. Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behaviour.

Energy efficient buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third, and help controlling global emissions of greenhouse gases, according to the International Energy Agency.

Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy.
