Are students getting enough air?

Roughly 85 percent of recently installed HVAC systems in K-12 classrooms investigated in California did not provide adequate ventilation, according to a study from the University of California, Davis, and Lawrence Berkeley ...

Fish simulations provide new insights into energy costs of swimming

A new computational analysis suggests that maximizing swimming speeds while minimizing energy costs depends on an optimal balance between a fish's muscle dynamics and the way its size, shape, and swimming motion affect its ...

Improving indoor air quality during wildfires

In California and other U.S. western states, wildfires have become more frequent and intense, adversely impacting air quality and human health. Smoke from wildfires contains many toxins and irritants, including particles ...

Cleaning up 'dirty' ceramic tile production

Energy efficiency in kilns and other process stages of ceramics production are quite low and pollutants are currently emitted at unsustainable levels. But as costs for fossil fuels rise and governments impose ever tighter ...

Would a carbon tax help to innovate more-efficient energy use?

Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in Joule from Carnegie's Rong Wang (now at Fudan University), Harry Saunders, and Ken Caldeira, along ...

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.
