Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers
Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand. view more (2009-10-20)
Popcorn-ball design doubles efficiency of dye-sensitized solar cells
A new approach is able to create a dramatic improvement in cheap solar cells now being developed in laboratories. view more (2008-04-11)
Hinode: new insights on the origin of solar wind
Spectacular images and data from the Hinode mission have shed new light on the Sun's magnetic field and the origins of solar wind, which can disrupt power grids, satellites and communications on Earth. view more (2007-12-10)
Press Invitation: Cleaner & cheaper sources of energy: EU Research on photovoltaics and bio-energy
What? Presentation of European research projects into photovoltaic and bio-energy technologies view more (2004-09-28)
NASA's GLAST Satellite Gets Twin Solar Panels in Prep for Launch
Preparations for launching NASA's Gamma-ray Large Area Telescope (GLAST) satellite are underway at NASA's Kennedy Space Center (KSC), Fla. NASA KSC's "NASA Expendable Launch Vehicle Status Report" on Thursday, March 20, noted that GLAST's twin solar panels have been attached. view more (2008-04-02)
Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated. view more (2006-12-12)
Hinode reveals new insights about the origin of solar wind
Images from NASA-funded telescopes aboard a Japanese satellite have shed new light about the sun's magnetic field and the origins of solar wind, which disrupts power grids, satellites and communications on Earth. view more (2007-12-07)
Rooftop PV data for better energy prediction models
New generations of photovoltaic (PV) roofing products utilize designs that allow them to be integral parts of the roof, providing both electricity and shelter from the elements. view more (2006-06-28)
Cost Competitive Electricity from Photovoltaic Concentrators Called 'Imminent'
Solar concentrators using highly efficient photovoltaic solar cells will reduce the cost of electricity from sunlight to competitive levels soon, attendees were told at a recent international conference on the subject. Herb Hayden of Arizona Public Service (APS) and Robert McConnell and Martha Symko-Davies of the U.S. Department of Energy's... view more... (2005-07-18)
Earth's magnetic field could help protect astronauts working on the moon
It has been 35 years since humans last walked on the moon, but there has been much recent discussion about returning, either for exploration or to stage a mission to Mars. However, there are concerns about potential radiation danger for astronauts during long missions on the lunar surface. view more (2007-12-11)
NASA spacecraft ready to explore outer solar system
The first NASA spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space is ready for launch Oct. 19. The two-year mission will begin from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. view more (2008-10-07)
Effective solar cells and sensitive bioanalysis
The efficiency factor of solar cells is crucial for the success of generating electricity from sunlight. Systems in which light is concentrated 400-fold through lenses onto solar cells are proving to be particularly advantageous. view more (2009-06-26)
Europe at the forefront in research on solar, wave and geothermal energies
Today at the "Solar platform" test site in Almeria (Spain) the European Commission presented the state of play on its research programmes in alternative energy sources, including solar thermal, wave and geothermal energy. World energy consumption will double over the next 50 years, with Europe currently depending heavily on foreign... view more... (2004-03-17)
Protective Storm in Space - a new explanation for the death of the dinosaurs
A shower of matter from space millions of years ago could have led to drastic changes in the Earth's climate, followed by the extinction of life on a massive scale, which also killed off the dinosaurs. This at least is a theory put forward by scientists from the University of Bonn. Normally, the solar wind acts as a shield against showers of... view more... (2002-06-04)
Atmospheric 'Sunshade' Could Reduce Solar Power Generation
The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according to a new NOAA study. The findings appear in this week's issue of Environmental Science and Technology. view more (2009-03-12)
Winds of 320 000 kilometres per hour on the Sun
The SUMER instrument on the ESA-NASA SOHO spacecraft has measured amazing wind speeds during its observations of the Sun. It sets a new record in its examination of two loops of gas arching in the solar atmosphere, where NASA`s TRACE satellite spotted bright blobs of gas. Shifts in the wavelength of ultraviolet light from highly ionized neon... view more... (2002-05-17)
Chemists describe solar energy progress and challenges, including the 'artificial leaf'
Scientists are making progress toward development of an "artificial leaf" that mimics a real leaf's chemical magic with photosynthesis - but instead converts sunlight and water into a liquid fuel such as methanol for cars and trucks. view more (2009-11-06)
ESA studies the Sun-Earth climate link
Meteorologists can no longer view the Earth as an isolated system. Both long-term climate changes and day-to-day weather show links with the Sun`s activity. Scientists therefore study the nature of those links intensely. With data from ESA`s spaceprobes SOHO, Cluster, and Ulysses, we now have the information we need to solve the mystery of how the... view more... (2002-08-23)
NASA Scientists Closer to Timely Space Weather Forecasts
Scientists funded by NASA have made big strides in learning how to forecast "all clear" periods, when severe space weather is unlikely. The forecasts are important because radiation from particles from the sun associated with large solar flares can be hazardous to unprotected astronauts, airplane occupants and satellites. view more (2005-08-18)
