US wind generation reached 5.5% of the grid in 2016

Iowa, South Dakota, Kansas, Oklahoma and North Dakota all sourced more than 20 percent of their electricity generation from wind power during 2016, according to new data from the U.S. Energy Information Administration (EIA). It shows wind supplied over 5.5 percent of electricity nationwide, up from 4.7 percent in 2015.  With 99 percent of wind turbines located in rural areas, wind power's steady growth as a share of the nation's electricity supply has been accompanied by a surge of investment in rural America. The industry invested over $13.8 billion in new turbines last year, according to the American Wind Energy Association (AWEA), in addition to operating a fleet now over 52,000 turbines.   Full AWEA Press Release:

US Military Moves Ahead With Renewable Energy Plan

Shoshanna Delventhal for Investopedia:  The Trump administration’s stance on climate change and the environment can be summed up by the chief White House strategist’s recent criticism of government support of green energy as “madness.” Despite a 180-degree shift from Obama administration’s environmental agenda, the Department of Defense, plans to move forward with a decade-long effort to “convert its fuel-hungry operations to renewable power,” senior military officials told Reuters. Yet apart from the controversial debate on climate change and the need for environmental protection, the Department of Defense has a strictly nonpolitical incentive to carry out the transition. Weaning reliance off petroleum means improved safety for U.S. troops and the American public.   Cont'd...

Stabilizing battery storage

Morgan Sherburne for U of Michigan News:  An issue that has long plagued renewable energy facilities is how to efficiently store energy collected from sun or wind. Now, University of Michigan and University of Utah chemists have developed an energy-storing molecule that is 1,000 times more stable than current compounds, potentially leading to a longer-lived, more efficient battery. The researchers are working to develop industrial-scale batteries that can store large amounts of energy for deployment when the sun sets or the wind stops blowing. Deep-cycle lead batteries or lithium ion batteries are already on the market, but each type presents challenges, including the significant environmental hazards of disposal. Also, these kinds of batteries wear out relatively quickly.   Cont'd...

SDG&E Unveils World's Largest Lithium Ion Battery Energy Storage Facility

Today, SDG&E is showcasing the world's largest lithium-ion battery energy storage facility in partnership with AES Energy Storage, which will enhance regional energy reliability while maximizing renewable energy use. The 30 megawatt (MW) energy storage facility is capable of storing up to 120 megawatt hours of energy, the energy equivalent of serving 20,000 customers for four hours.  Last year, the California Public Utility Commission (CPUC) directed Southern California investor-owned electric utilities to fast-track additional energy storage options to enhance regional energy reliability. In response, SDG&E expedited ongoing negotiations and contracted with AES Energy Storage to build two projects for a total of 37.5 MW of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was built in El Cajon.   Full Press Release:

California demand for wind power energizes transmission firms

Nichola Groom for Reuters:  A firm controlled by Philip Anschutz, the billionaire entertainment and pro sports magnate, will soon build the largest wind farm in the United States to serve utilities in California, where officials have set ambitious green power goals. The $5 billion project, however, will be constructed 700 miles away in Wyoming, a state better known for coal mines and oil fields. The vast distance between the two states provides a different Anschutz-owned firm with another big opportunity: a $3 billion project building transmission lines to deliver the power - one of a dozen similar power-line projects by other companies across the West. (Map: How wind power will get from Wyoming to California click here) In all, about 5,700 miles of transmission lines are in development with the goal of delivering renewable energy to California from other states, according to the Western Interstate Energy Board.   Cont'd...

Scientists invented a battery that could work for a decade without degrading

Mike Wehner for BGR:  Energy storage degradation in rechargeable batteries is a pretty serious problem that many of us put up with on a regular basis. It’s why your iPhone seems to last forever when it’s brand new out of the box but seems like it dies by lunchtime after a couple of years of use. Now, researchers at Harvard have developed a new battery technology using a bit of chemistry magic to create a rechargeable power source that could be tapped for many years with very little in the way of maintenance.

Stanford engineers create a low-cost battery for storing renewable energy

Jackie Flynn for Stanford News:  A battery made with urea, commonly found in fertilizers and mammal urine, could provide a low-cost way of storing energy produced through solar power or other forms of renewable energy for consumption during off hours. Developed by Stanford chemistry Professor Hongjie Dai and doctoral candidate Michael Angell, the battery is nonflammable and contains electrodes made from abundant aluminum and graphite. Its electrolyte’s main ingredient, urea, is already industrially produced by the ton for plant fertilizers. “So essentially, what you have is a battery made with some of the cheapest and most abundant materials you can find on Earth. And it actually has good performance,” said Dai. “Who would have thought you could take graphite, aluminum, urea, and actually make a battery that can cycle for a pretty long time?”   Cont'd...

Saudi Arabia Plans the World's Cheapest Power With Solar and Wind

Wael Mahdi for Bloomberg:  Saudi Arabia will award its first tender to build 700 megawatts of solar and wind energy in September, with the cost of power forecast to be the lowest in the world, Energy Minister Khalid Al-Falih said. OPEC’s biggest oil producer plans to build 300 megawatts of solar plants in the al-Jouf area in northern Saudi Arabia and 400 megawatts of wind projects in nearby Tabuk, he said. Requests to qualify for bidding will be issued Feb. 20 and bids will be on April 17. “The terms on renewable contracts will be motivating so that the cost of generating power from these renewable sources will be the lowest in the world,” Al-Falih said Wednesday at a press conference in Riyadh.   Cont'd...

Mercom: Project funding for energy storage totalled US$820 million in 2016

Andy Colthorpe for Energy Storage News:  Project funding for energy storage jumped to US$820 million in 2016 from just US$30 million in 2015, while Sonnen was revealed as the energy storage company to raise the most VC funding this year.

SolPad Releases Pricing & Pre-Order Info For Mobile Solar + Storage Product

Derek Markham for CleanTechnica:  The Silicon Valley startup SolPad has just announced the specs, pricing, and pre-order date for its all-in-one solar plus storage mobile solution, which could help usher in a new era of entry-level solar. We first covered the SolPad product back in October of last year, with writer Matthew Klippenstein calling it “a glimpse of the future.” That article raised a lot of questions in the comments section about the details and reliability of such a device. Some of those comments called it vaporware, while others questioned the wisdom of integrating batteries into the body of a solar panel and the legality of simply plugging such a system into the grid without an adequate grid-tie arrangement, and still others asked why it was even needed with the current state of solar technology. Most of which were decent skeptical questions, and all of which are expected on a piece about a forthcoming “breakthrough” solar product. However, it looks like the SolPad Mobile is getting ready to enter the market, as the company has released additional details about how much it will cost and when it will be available, so we’ll soon get an opportunity to see how the product will be received once it is released into the wild, so to speak.   Cont'd...

Solar panel researchers investigate powering trains by bypassing grid

Michael Holder for BusinessGreen, part of the Guardian Environment Network:  Imperial College London has partnered with the climate change charity 10:10 to investigate the use of track-side solar panels to power trains, the two organisations announced yesterday. The renewable traction power project will see university researchers look at connecting solar panels directly to the lines that provide power to trains, a move that would bypass the electricity grid in order to more efficiently manage power demand from trains. According to the university, the research team will be the first in the world to test the “completely unique” idea, which it said would have a “wide impact with commercial applications on electrified rail networks all over the world”.   Cont'd...

Panasonic Commits To Solar Cell Production With Tesla At New York Plant

Alan Ohnsman for Forbes:  Panasonic will make solar cells with Tesla at a factory under construction in Buffalo, New York, broadening a partnership between the electric-car maker and Japanese electronics giant that goes back nearly a decade. The companies said in a joint statement today that they finalized plans to produce high-efficiency photovoltaic cells at the plant, with initial production scheduled for the second half of 2017. Output of the energy modules, for use in solar panels, Tesla’s planned solar roofs and to charge up Tesla’s Powerwall and Powerpack battery storage units, is to reach 1 gigawatt by 2019, the companies said.

Instead Of Trump's Wall, Let's Build A Border Of Solar Panels

Homero Aridjis & James Ramey for Huffington Post:  President-elect Donald Trump has repeatedly called for Mexico to build a wall between our countries. There is indeed a way that Mexico could create a barrier between the U.S. and Mexico, one constructed exclusively on the Mexican side, with substantial benefits for both countries and the planet: a solar border. Sunlight in the northern deserts of Mexico is more intense than in the U.S. Southwest because of the lower latitude and more favorable cloud patterns. And construction and maintenance costs for solar plants in Mexico are substantially lower. Thus, building a long series of such plants all along the Mexican side of the border could power cities on both sides faster and more cheaply than similar arrays built north of the border.   Solar energy is already being generated at lower prices than those of coal. With solar plants along vast stretches of the almost 2,000-mile U.S.-Mexico border on the Mexican side, a new high-voltage direct-current (HVDC) grid could be set up to transmit energy efficiently from that long, snaking array to population centers along the border. HVDC power lines lose exponentially less energy over long distances than traditional power lines.   Cont'd...

Batteries Need to Get Big-Like, Enormous-for Solar Power to Shine

Vaclav Smil for IEEE Spectrum:  It would be a lot easier to expand our use of solar and wind energy if we had better ways to store the large quantities of electricity we’d need to cover gaps in the flow of that energy. Even in sunny Los Angeles, a typical house roofed with enough photovoltaic panels to meet its average needs would still face daily shortfalls of up to about 80 percent of the demand in January and daily surpluses of up to 65 percent in May. You can take such a house off the grid only by installing a voluminous and expensive assembly of lithium-ion batteries. But even a small national grid—one handling 10 to 30 gigawatts—could rely entirely on intermittent sources only if it had gigawatt-scale storage capable of working for many hours. Since 2007, more than half of humanity has lived in urban areas, and by 2050 more than 6.3 billion people will live [PDF] in cities, accounting for two-thirds of the global population, with a rising share in megacities of more than 10 million people.   Cont'd...
