A research team led by pioneering clean energy technology developer and MIT professor Daniel Nocera has developed an ‘artificial leaf’ that like its namesake captures energy from sunlight and produces electricity that it then turns into chemical fuel — hydrogen and oxygen gas.

Using solar thermal energy to power an air conditioning unit can be difficult and expensive. But a team of researchers at the University of California, Merced, have added a game-changing advance to the process that could make it much simpler, less costly and more effective.

Much of what you hear from Pike Research is focused on alternatives to the gasoline-fueled internal combustion engine (ICE). Yet, as we often point out, gas-fueled ICE vehicles will remain the dominant vehicle through this decade and likely well into the next.

A team from the National University of Singapore's Nanoscience and Nanotechnology Initiative (NUSNNI), led by principle investigator Dr Xie Xian Ning, has developed the world's first energy-storage membrane. Electrical energy storage and its management is becoming an urgent issue due to climate change and energy shortage.

Despite the recent collapse of solar manufacturer Solyndra, the U.S. Department of Energy awarded loan guarantees totaling $1.074 billion Wednesday to two solar companies developing power plants -- one in Nevada and the other near Phoenix.

A team from the Carnegie Global Ecology department have recently concluded that water evaporation on Earth actually cools down the atmosphere and fights global warming, but not in the way you'd be tempted to think.

Nanometre-sized bubbles containing the gases hydrogen and oxygen can apparently combust spontaneously, although nothing happens in larger bubbles. For the first time, researchers at the University of Twente's MESA+ Institute for Nanotechnology have demonstrated this spontaneous combustion in a publication in Physical Review E.

Sustainable energy consumption, the use of renewable energies, energy efficiency and the reduction of CO2 emissions are the current challenges that cities and communities must overcome if they want to achieve the ambitious energy and climate targets if they want to achieve the set out by the EU in their EU 2020 strategy.

A team led by mechanical engineers Joseph Oefelein and Jacqueline Chen of Sandia National Laboratories (Sandia) simulates turbulent combustion at different scales. A burning flame can manifest chemical properties on small scales from billionths of a meter up to thousandths of a meter, whereas the motion of an engine valve can exert effects at large scales from hundredths of a meter down to millionths of a meter.

More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat – an age-old problem - but researchers have found a new way to make "thermoelectric" materials for use in technology that could potentially save vast amounts of energy. And it's based on a device found everywhere from kitchens to dorm rooms: a microwave oven.
