A solar-powered plane has landed in Texas, completing the second leg of a trip across the U.S.
Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing.
Engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.
A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year.
Since there is increasing interest in harnessing the currents and tides for energy, scientists need to know as much about the environment as they can, but the noise of gravel on the seafloor is so loud it's getting in the way of studies.
Compressed air energy storage plants could help save the Northwest's abundant wind power— which is often produced at night when winds are strong and energy demand is low— for later, when demand is high and power supplies are more strained.
Physicists have found a way to make sophisticated 3D images without using conventional digital cameras. Their system uses simple, cheap detectors that have just a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
Researchers have reported the first fully integrated nanosystem for artificial photosynthesis.
Researchers have found that the key to purple bacteria’s light-harvesting prowess lies in highly symmetrical molecules.
The government has prosecuted oil companies when birds drown in their waste pits, power companies when birds are electrocuted by their power lines but has never fined or prosecuted a wind-energy company when birds hit their fans.
Imaging revealed what happens during battery charging and could lead to improved batteries for electric cars.
In 2015, NASA will, for the first time, fly a space mission utilizing a radically different propellant— one which has reduced toxicity and is environmentally benign.
What unintended consequences could cleaner energy sources have on the changing climate?
Solar engineers have developed an innovative method to dramatically improve the quality of low-grade silicon, promising to significantly improve electrical efficiency and reduce the cost of solar panels.
Metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors.
In the race to conquer energy technology, old energy is beating green energy. Oil companies have used technology to find a bounty of oil and natural gas so large that worries about running out have melted away.
Universal access to modern energy could be achieved with an investment of between 65 and 86 billion U.S. dollars a year up until 2030.
In a tough economy clean technology investment funds are no longer trying to replace the fossil fuel industry, they're trying to help it by financing companies that can make mining and drilling less dirty.
The way plants transport important substances across their biological membranes, increase salt and drought tolerance, control water loss and store sugar can have profound implications for increasing the supply of food and energy around the world.
New research could dramatically improve the efficiency of fuel cells, which are considered a promising alternative to batteries for powering everything from electronic devices to cars and homes.
New experiments in a tokamak fusion reactor revealed details of a cooling process, potentially bringing practical fusion closer.
Changing the way a plant forms cellulose may lead to more efficient, less expensive biofuel production.
A graphene inspired electrode material that could help batteries hold more power has been developed.
Innovative storage system could enable offshore wind farms to deliver power whenever it’s needed.
A catalyst, made from renewable soybeans and abundant molybdenum metal, produces hydrogen in an environmentally friendly, cost-effective manner, potentially increasing the use of this clean energy source.
