Solar Power Thrives In Chile, No Subsidies Needed
William Pentland, Contributor for Forbes: In Chile’s most recent power auction, the bids from solar project developers came in at between $65 and $68 per megawatt hour (MWh) were considerably more competitive than bids made by coal plants, which were priced at $85 per MWh. Solar power projects were awarded the lion’s share of the 1,200 gigawatt hours (GWh) of electricity contracts sold.
Chile boasts one of the world’s biggest solar resources. High electricity prices and strong demand from Chile’s mining industry have driven demand growth for solar, especially large scale commercial or utility projects.
The total installed solar capacity in Chile increased from less than 4 MW in 2013 to more than 220 MW last year. Nearly 1 GW of solar is projected to be installed in Chile in 2015. Meanwhile, a total of about 8 GW of solar power projects have been approved for development in Chile. First Solar and SunEdison are two of the biggest U.S. solar companies active in Chile. Cont'd...

UK building the world's largest offshore wind farm
By Kelly Hodgkins for Digital Trends: Danish state-owned company Dong Energy A/S plans to set a new world record for the world’s largest offshore wind farm, breaking the existing record currently held by the 630-megawatt London Array, another facility built by Dong. The new U.K. wind farm will be located in the Irish Sea, about 12 miles off the west coast of Great Britain. When commissioned, it will provide enough energy to power almost a half million homes.
It’s no surprise that Dong is behind this effort, as it is Denmark’s largest energy company and the world’s largest developer of offshore wind power. The company has a longstanding relationship with the UK, constructing and, in some cases, operating multiple offshore wind facilities, including those in Barrow, Burbo Bank, and Walney Island. Between these projects and others in Germany, Dong now has a total of 5.1 gigawatts of offshore wind capacity. It aims to expand this capacity even further with a projected goal of 6.5 gigawatts of offshore wind energy production by 2020. Cont'd...
Morocco to Build World's Largest Concentrated Solar Power Plant
Cole Mellino for EcoWatch: Morocco imports 97 percent of its energy, and yet it has one of the highest rates of solarinsolation of any country—about 3,000 hours of sunshine per year, according to the Solar GCC Alliance. To put that in perspective, the Guinness Book of World Records puts Yuma, Arizona as the sunniest place on Earth with an average of 4,055 hours of sunshine per year (the theoretical maximum is 4,456), whereas the sunniest place in Germany, which still has a robust solar industry, gets a mere 1,800 sunshine hours a year. So it’s no surprise that Morocco is tapping into its abundant sunshine for energy.
Morocco is building “a complex of four linked solar mega-plants that, alongside hydro andwind, will help provide nearly half of Morocco’s electricity from renewables by 2020,” reports The Guardian. When the entire project is finished, it will be the world’s largest concentrated solar power plant in the world. The first phase, Noor 1, will go live next month. Cont'd...

As California Rolls Out More Solar Power, Regulators Could Undercut The Industry
Ken Silverstein for Forbes: The fall season is kicking off a sizzling solar power debate in California and one that has the potential to undercut the state’s climate mission.
Utility regulators there are in discussions over how to balance the interest of rooftop solar generators with the utilities on which they will still depend. Just how those hearings are resolved with have implications for the rollout of renewable energy not just in California but also around the country.
At issue is something called “net metering,” which is technical term used to measure the amount of money that rooftop solar generators should get paid relative to retail electricity prices. Utilities, generally, want to offer them the wholesale rate for what they send to them over the grid. Those are expensive wires to maintain and ones that all customers will use, even those who power their homes with solar panels. That’s because the sun is not always shining and the utilities would then have to provide them electricity over their networks.
The present net metering rules in California were set a dozen years ago, with the intent that they would expire when solar penetration reached 5 percent at any of three investor-owned utilities: Edison International’s SoCalEd, PG&E Corp. and Sempra Energy, which is nearing the threshold. Generally, those utilities are paying customers the full retail value for their electricity generated and transmitted. Cont'd...

Wind turbine technology stores excess wind power for when gusts turn to breezes
Megan Treacy for TreeHugger: A new technology developed by University of Nebraska-Lincoln electrical engineering doctoral student Jie Cheng solves both of those problems by harnessing the excess wind energy usually wasted as spillage and storing it for use when wind speeds dip, making wind turbines more efficient and consistent.
Cheng's system converts and directs the extra wind energy to an air compression tank, where the energy is stored until wind speeds dip below the maximum capacity. Using a rotary vane machine that is connected between the turbine's gearbox and generator, excess energy is diverted and stored in the air compression tank. When the wind dies down, the tank then kicks in and reverses airflow back to the rotary vane machine to generate electricity.
In a recent study of his prototype, Cheng found that a 250-kW system would produce an additional 3,830 kWh of electricity per week or an additional 16,400 kWh per month based on historical wind data from Springview, Nebraska. That extra electricity is about 18 times the monthly energy use of a typical American household. Cont'd...
Obama pledges $120M toward solar power, clean energy
By Timothy Cama for The Hill: The Obama administration announced Wednesday morning a series of efforts worth more than $120 million aimed at boosting solar and other clean energy sources.
The initiatives focus on the Department of Energy, where the bulk of the funding will go to programs to develop solar power technology and get it into homes, businesses and other facilities.
“President Obama and Vice President Biden are committed to promoting smart, simple, low-cost technologies to help America transition to cleaner and more distributed energy sources, help households save on their energy bills, and to address climate change,” the White House said in a fact sheet outlining the efforts.
“All told, this funding will drive the development of affordable clean energy throughout the country,” it said.
The actions aim to help out solar power in 24 states, officials said. Cont'd...
