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 ...

Researchers use AI to plot green route to nylon

The chemical and allied industries face such challenges as ready access to reliable energy supplies, waste reduction, water conservation, and energy efficiency. Organic electrosynthesis—an electricity-driven, energy-efficient ...

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...

Ammonia for fuel cells

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient ...

China may be on track to meet its carbon emissions goals early

China, the world's largest carbon emitter today, may be on track to meet its emission goals up to a decade early, according to a recent study on the cover of Nature Sustainability led by researchers from Nanjing University ...

Climate battle will 'succeed or fail' in Asia: UN

The battle to combat climate change will "succeed or fail" based on what happens in Asia, where growing energy needs are increasing demand for fossil fuels, UN officials said Friday.

In the active center of carbon dioxide conversion

In order to overcome the climate crisis, two measures are required: The reduction of carbon dioxide (CO2) emissions, and removal of CO2 from the earth atmosphere. The latter is the goal of Tobias Erb's research group at the ...

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.
