Juno spacecraft breaks solar power distance record

Jim Sharkey for SpaceFlight Insider:  NASA’s Juno mission has broken the record for distance traveled by a solar-powered spacecraft. Juno reached this milestone at 11 a.m. PST (2 p.m. EST) on Wednesday, Jan. 13, when the spacecraft was approximately 493 million miles (793 million kilometers) from the Sun. The record was previously held by the European Space Agency’s (ESA)  Rosetta spacecraft, whose orbit peaked at the 492 million-mile (792-million kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko. “Juno is all about pushing the edge of technology to help us learn about our origins,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. “We use every known technique to see through Jupiter’s clouds and reveal the secrets Jupiter holds of our solar system’s early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it.” Juno is the first solar-powered spacecraft designed to operate so far from the Sun. Generating sufficient power to operate the spacecraft requires a very large area of solar cells. The four-ton Juno spacecraft carries three 30-foot (9-meter) solar arrays festooned with 18,686 individual solar cells. At Earth’s distance from the Sun, the cells can generate about 14 kilowatts of electric. The further away from the sun the spacecraft is, the lower the power its solar cell will be able to generate.   Cont'd...

These Creative Wind Turbines Will Have You Rethinking What You Know About Wind Power

By Alison Gillespie for SMITHSONIAN.COM: Although a lot of people are excited about wind energy, few are excited about the pinwheel-shaped machines that often produce it. Branded as noisy, blamed for spoiling bucolic views and proven deadly to some bats and migrating birds, the giant, white-bladed horizontal axis wind turbines that now dot the landscape of the American West have earned a fair number of detractors—even among environmentalists who generally favor renewable power. But what if you turned the idea sideways, and created a turbine that could spin like a carousel? And what if you made a turbine small enough to sit on top of a building or inside an urban park? Could the result produce enough power to really matter? The idea isn’t a new one—people have been playing with windmill designs and experimenting with alternatives to the horizontal axis turbine for almost a century now. But in the last two decades, a flurry of interest in expanding renewable energy in cities has attracted the attention of a large number of inventors and artists, many of whom see the vertical axis wind turbine as promising. There is no single design for these upended wind catchers, but all share one key aspect: the blades turn around an axis that points skyward. And unlike their horizontal brethren, the components and associated generators of a vertical turbine are placed at its base, giving it a lower center of gravity. Most are also relatively small, and unlike horizontal units, they can be grouped very closely together to optimize efficiency.   Cont'd...

Solar Surges Past Wind, Hydropower as State's No. 1 Renewable Energy Source

By Pete Danko for KQED News:  In just a few short years, solar power has gotten big in California, and now it’s at the top of the renewable energy heap. Data compiled from daily reports by the state’s major grid manager indicate that in 2015, solar became the No. 1 source of renewable energy in California. Not only did solar beat wind power for the first time, but it also topped drought-depleted hydropower, the long-standing leader in California electricity generation outside fossil fuels and nuclear. The California Independent System Operator doesn’t cover the entire state, but it does manage about 80 percent of the California grid, including those portions served by PG&E, Southern California Edison and San Diego Gas & Electric, the state’s three big investor-owned utilities. Every day, CAISO reports on the hourly electrical output from a long list of sources for the electricity used by 30 million Californians, ranging from biogas at the low end of generation to thermal — natural gas, essentially — at the high end.   Cont'd...

Is this sunny state trying to kill solar power?

Claudia Assis for MarketWatch:  Nevada has turned into a sunny battleground for the future of solar in the U.S., with regulators there moving to make solar power less attractive to homeowners and businesses and pitching utilities against solar-power companies. SunRun Inc. on Thursday said it was pulling out of Nevada, which the company said will result in “hundreds” of job losses. A day earlier, SolarCity Corp. announced the same move, saying that about 550 jobs would be lost. The Solar Energy Industries Association estimates that nearly 6,000 people in Nevada are employed in the solar industry. Besides affecting jobs, the new rules cut down on the savings that many homeowners count on from going solar.   Cont'd...

Wind, solar power soaring in spite of bargain prices for fossil fuels

Joby Warrick for The Washington Post: Wind and solar power appear set for a record-breaking year in 2016 as a clean-energy construction boom gains momentum in spite of a global glut of cheap fossil fuels. Installations of wind turbines and solar panels soared in 2015 as utility companies went on a worldwide building binge, taking advantage of falling prices for clean technology as well as an improving regulatory and investment climate. Both industries have seen stock prices jump since Congress approved an extension of tax credits for renewables as part of last month's $1.14 trillion budget deal. Orders for 2016 solar and wind installations are up sharply, from the United States to China to the developing economies of Africa and Latin America, all in defiance of stubbornly low prices for coal and natural gas, the industry's chief competitors.

Sand could be the key to unlocking more efficient solar power, Masdar scientists find

Naser Al Wasmi for The National UAE:  Masdar Institute scientists have published a breakthrough research into more efficient solar power – and they will not have to look far for the raw material ­needed. Using sand, they hope to drive concentrated solar power technology to compete with the traditional photovoltaic method. Named “Sandstock”, the research published at the Solar Power and Chemical Energy Systems Conference in South Africa yesterday, showed sand can withstand temperatures of up to 1,000°C. Concentrated solar power, or CSP, uses mirrors to reflect heat from the sun to one point, most typically a tower filled with a material capable of storing heat and then converting it into electricity. CSP’s benefit is that the energy derived is easy to store, but in recent years it has lost out to the more popular photovoltaics, which is more cost-efficient. That may now change. “Sand is really always a drawback in this country but in this project we wanted to use it as an advantage because it can withstand very high temperature, and of course it is very cheap here,” said Dr Nicolas Calvet, assistant professor of mechanical and materials engineering, and guide for the research project.   Cont'd...

China to cut on-grid tariffs for solar, wind power: State planning commission

Reuters - China will cut payments to wind and solar electricity generators for contributing power to the grid, the country's state planning commission said over the weekend, reflecting recent declines in operating costs. Starting in 2016, on-grid tariffs for solar producers will be 0.02 to 0.10 yuan lower per kilowatt-hour — with the higher cuts applying in the country's less populated, arid western region — while tariffs for wind power generators will fall 0.02 to 0.03 yuan, the National Development and Reform Commission said in a statement. The cuts, which were expected, are in line with a 0.03 yuan cut on Wednesday to on-grid tariffs for thermal power. Coal still fires more than 70% of China's power generation.   Cont'd...

Koch brothers defeat Harry Reid on solar power

By ESTHER WHIELDON for Politico:  Harry Reid’s home state dealt a lethal blow Tuesday to rooftop solar power — the latest skirmish of a nationwide green energy battle that has pitted the Senate Democratic leader against his favorite target, the Koch brothers. The move by Nevada’s utility regulator, which voted to slash the economic incentives for homeowners to install solar panels, was most immediately a showdown between billionaires Warren Buffett, owner of the state’s largest power company, and Elon Musk, whose SolarCity is the nation’s largest installer of panels that create electricity from the sun. But it also served as a proxy fight in a national struggle about states’ green energy programs, in which free-market groups backed by industrialists Charles and David Koch have fought to roll back incentives that they argue distort the marketplace and force some customers to subsidize other people’s power choices.   Cont'd...
