Revisiting energy flow in photosynthetic plant cells

By developing innovative methods to visualize energy changes in subcellular compartments in live plants, the team of Dr. Boon Leong Lim, Associate Professor of the School of Biological Sciences of The University of Hong Kong, ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Team unveils catalyst that can break problematic C-F bonds

Rice University engineers have created a light-powered catalyst that can break the strong chemical bonds in fluorocarbons, a group of synthetic materials that includes persistent environmental pollutants.

How stimulus dollars are spent will affect emissions for decades

The COVID-19 pandemic and subsequent lockdowns have led to a record crash in emissions. But it will be emission levels during the recovery—in the months and years after the pandemic recedes—that matter most for how global ...

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.
