Primary GOES-R instrument ready to be installed onto spacecraft - http://www.sciencedaily.com/release...
A key instrument that will fly on the Geostationary Operational Environmental Satellite-R (GOES-R) spacecraft, NOAA's next-generation of geostationary satellites, is cleared for installation on the spacecraft. The Advanced Baseline Imager, or ABI, is GOES-R's primary instrument for scanning Earth's weather, oceans, and environment and is a significant improvement over instruments on NOAA's current geostationary satellites. The ABI will offer faster imaging with much higher detail. It will also introduce new forecast products for severe weather, volcanic ash advisories, fire and smoke monitoring and other hazards.

Flames Shaped By Electricity Help Coal Plants Burn Cleaner - http://www.popsci.com/article...
Flame Oscar, CC BY-SA 3.0 One company is developing a cheap way to reduce pollution from power plants—and it does so by controlling the shape of fire. Okay, so that's not as magical as it sounds. As MIT Technology Review reports, scientists have long known the electrons and ions inside a flame respond to electric fields. But the company, ClearSign Combustion of Seattle, has developed a low-cost way to produce the high-voltage electric fields it needs to manipulate the flames inside fossil fuel-burning plants. ClearSign Combustion's technology uses little of a facility's overall electricity and reduces the amount of fuel a plant requires, so even developing countries may be able to afford it, MIT Technology Review reports. China and India both rely heavily on coal power and struggle with the resultant pollution. Giving flames just the right shape helps them burn at an even temperature throughout. That avoids both the too-high and too-low temperatures that produce extra pollution. Check...

Ikea Now Sells Solar Panels! - http://www.popsci.com/article...
IKEA Dudes Confused? IKEA, which is now selling solar panels in its Britain stores, will offer installation support. You got all your college furniture from there; now you can get solar panels from Ikea, too. The Swedish furniture company began selling solar panels in its Southampton, U.K., store today and plans to bring the product to all of its Britain stores in the new few months, the Associated Press reports. Don't worry, you don't need to put the panels together yourself. Ikea will also sell consultation, design, installation, maintenance and energy monitoring services, the AP reports. Home improvement stores in the U.S. do already sell home solar panels. But there's something about Ikea that makes the panels seem even more accessible. The level of handiness you need for Ikea furniture is definitely a step down from the kind of projects for which most people go to Home Depot or Lowe's. Britain is a test market, Ikea Chief Sustainability Officer Steve Howard told the AP. The...

Lunar orbiters discover source of space weather near Earth - http://www.sciencedaily.com/release...
Solar storms, powerful eruptions of solar material and magnetic fields into interplanetary space, can cause hazards on Earth known as space weather, ranging from interference with radio communications to extensive power blackouts, complete failure of critical satellites and even the shutdown of GPS-guided transportation and global communication systems. New research increases our understanding of our space environment, and explains the source of Earth's space weather.

Emissions and costs of power plant cycling necessary for increased wind and solar calculated - http://www.sciencedaily.com/release...
New research quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West. To accommodate higher amounts of wind and solar power on the electric grid, utilities must ramp down and ramp up or stop and start conventional generators more frequently to provide reliable power for their customers -- a practice called cycling.

World record solar cell with 44.7% efficiency - http://www.sciencedaily.com/release...
Researchers in Germany report a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. A new record efficiency of 44.7% was measured at a concentration of 297 suns, indicating that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. The achievement is being hailed as a major step towards reducing the costs of solar electricity.

Clean energy least costly to power America's electricity needs - http://www.sciencedaily.com/release...
Findings show carbon pollution from power plants can be cut cost-effectively by using wind, solar and natural gas. It’s less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study.

Scientists calculate the energy required to store wind and solar power on the grid - http://www.sciencedaily.com/release...
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution. But a new study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind.
