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...
French Biofuel Maker Is Tested by $35 Oil Despite Tax Breaks
Francois De Beaupuy for Bloomberg: Global Bioenergies SA, an unprofitable French maker of sugar-based gasoline, said oil’s recent slump to $35 a barrel is testing the financial viability of its technology even as it plans expansion in the U.S.
“The economic case doesn’t stand with oil at $35, except when there’s a tax incentive” as in various European countries and the U.S., Chief Executive Officer Marc Delcourt said in an interview. Without tax breaks, the company would need Brent crude well above $100 a barrel, he said.
Shares of Global Bioenergies, listed in Paris since 2011, have dropped more than 50 percent from their peak in May as oil’s collapse raised investor concern that biofuel makers couldn’t compete. Delcourt is counting on the end of European sugar production quotas in 2017 and changes in U.S. eating habits to keep the sweetener’s price low as it eyes additional capacity. Raw-sugar futures are trading at half their price five years ago. Cont'd...
Wind, solar power soaring in spite of bargain prices for fossil fuels
Joby Warrick for The Washington Post: Â 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 months $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 industrys chief competitors. Â Cont'd...
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.

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...
CES 2016 - Autonomous Cars Set To Dominate
BY DAVID GILBERT For International Business Times:   As cars become less about horsepower and torque and more about the technology inside, CES has become one of the most important showcases of the year for auto manufacturers. It's a sea change in how cars are built and marketed, with technology now the core, rather than an added feature. Connected, autonomous and electric vehicles will all be on display at CES 2016, with some of the worlds most talk-about companies in the field looking to make a major impact.
First up will be Faraday Future, the secretive startup based in Los Angeles and backed by a Chinese billionaire. It is set to unveil its first ever concept design on Jan. 4, and while all the company has said so far is that it will be an electric vehicle, it is widely believed to feature autonomous capabilities.
While Faraday Future is a relative unknown, one of the worlds biggest automotive companies, Ford, will also be at CES announcing news about the autonomous car it has been testing internally for several years. Among the announcements expected is apartnership with Google to build some of Googles fleet of self-driving cars.  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.

Japanese Towns Bank on Renewable Energy
By MAYUMI NEGISHI for the WallStreet Journal: Japanese cities are entering the renewable-energy business, the latest phase in a shake-up of the nation’s power sector in the aftermath of the 2011 Fukushima nuclear crisis.
So far, about 14 cities have formed companies to generate clean energy from local resources and sell it to area businesses and homes. With full deregulation of the nation’s electricity markets set to begin next year, the government aims to have 1,000 such city-operated companies up and running by 2021 in a direct challenge to regional power monopolies.
The move is part of Japan’s strategy for creating energy self-sufficiency, while helping revitalize communities with infrastructure investment. Cont'd...
Spending and Tax Deal Brings ITC and PTC Extensions
Sahir Surmeli for National Law Review: Early Wednesday morning Congressional leaders reached agreement on a year-end spending and massive tax deal that would prevent a government shutdown and extend a series of tax breaks that benefit businesses and individuals. The agreement has major implications for the future of the energy industry and is being hailed by many as a dramatic victory for those in the renewable energy community.
The Investment Tax Credit (ITC), which was slated to drop to 10 percent from 30 percent for solar systems on commercial properties after 2016, would now remain at 30 percent for projects that start construction by December 31, 2019. Projects that start construction in 2020 would qualify for a 26 percent credit and that level would drop to 22 percent for facilities started in 2021. From 2022 on it would remain at 10 percent.

Could this be the future of biofuels?
Anmar Frangoul for CNBC: A common sight in the British countryside, bracken -- a type of fern -- is now being hailed as the next big source of biofuel.
Based in the south west of England, Brackenburn produces "brackettes" – biomass pellets made from bracken that they shred and compress into briquettes which produce much more heat when burnt than oak.
"In our estimation there's 2.5 million acres of bracken in the UK… it's a huge area," Barry Smith, Brackenburn's marketing and sales director, told CNBC in a phone interview.
"Left unchecked, bracken encroaches by three percent a year… at the end of the day there's no use for it whatsoever," Smith added. "It's a nuisance and to call it a crop is kind of giving it a status it doesn't deserve." Cont'd...
Energy Storage in Underwater Balloons
Tom Lombardo for Enegineering.com : Grid-level energy storage takes many forms, including flow batteries, Li-ion batteries, pumped hydro, compressed air in underground caverns, and even flywheels. Toronto’s Hydrostor just added another tool to the arsenal: underwater compressed air energy storage (UCAES). Hydrostor recently activated a pilot UCAES plant - the first of its kind - that will provide grid-level storage for the city of Toronto. In addition to supplying the city with cost-effective energy storage, the system will allow engineers to study its behavior and optimize the design. Can UCAES become a viable energy storage technology?
The idea has been around for many years: when supply exceeds demand, use the excess energy to run an air compressor and store the air in an underwater balloon. When power is needed, open a valve and let the compressed air run a turbine to generate electricity. The principle is simple, but the economic feasibility has yet to be demonstrated. Hydrostor hopes that their facility becomes the proving ground. Cont'd...
China Finds New Funding Model to Allow Free Solar Panel Installation
Manny Salvacion for Yibada: Singapore-based real estate investment firm Redwood Group has recently launched a 248-kilowatt (KW) pilot project in China. The company also signed a power purchase agreement with New York-based solar developer UGE International and its financing partner, Hong-Kong's Blue Sky Energy Efficiency Co.
Under the Redwood deal, UGEI and Blue Sky would lease rooftop space from Redwood to operate solar panels and then sell the electricity back to Redwood, the building owner, at prices lower than grid rates.
"The time is right now for solar on rooftop in China because the cost of putting a system on the roof is becoming much more attractive," said Tianyu Sieh, chief executive of Blue Sky.
UGEI and Blue Sky have also partnered with real estate services firm Jones Lang LaSalle in China to offer the same model to its commercial clients. Full article:
36 countries launch world alliance for geothermal energy
Thirty-six countries gave the official start Monday to an initiative to promote geothermal energy in developing economies as a cleaner alternative to oil, gas and coal.
The Global Geothermal Alliance, launched on the sidelines of the UN climate talks in Le Bourget, aims at a sixfold increase in geothermal electricity production and a tripling of geothermal-derived heating by 2030.
At present, geothermal is growing modestly, at three to four percent per year, providing 12 gigawatts of electricity annually.
But this is just a fraction of its overall potential of 100 gigawatts, according to the industry. Only 24 out of 90 countries with geothermal potential actually use the resource.
The alliance said its members will seek to overcome "political uncertainty" about geothermal and strengthen the industry's skills base.
The Global Geothermal Alliance initiative was sketched out in September 2014 at a summit organised by UN Secretary General Ban Ki-moon.
Members include countries on thermal "hotspots" in Africa, Southeast Asia and Latin America, ranging from Kenya and Tanzania to Malaysia, the Philippines and Guatemala. Cont'd...
Tidal power: An inside look at how it works
From EnergyDigital: Tidal power, a sister resource to wind, takes advantage of the predictability of the ocean tides to generate electricity, either via estuary barges or directly from the currents themselves via tidal streams. According to the Ocean Energy Council, the ideal area to net the most potential power is an area with a tidal range of at least seven meters. Energy can be generated via floating devices that drive hydraulic pumps, oscillating water columns within cylindrical shafts to create air movement, or hydropower turbines.
The Pacific Northwest coast of the United States is an excellent location for tidal power, given its broad range of tide movement. According to Renewable Northwest, some areas of potential development include:
• Makah Bay, Washington (by AquaEnergy Group)
• Newport, Oregon (by Oregon State University / Oregon Department of Energy)
• Tacoma Narrows (by Tacoma Power)
• Puget Sound (by Snohomish County Public Utility District)
The following sites are under development in Wales due to their wide tidal height variation and economically receptive marketplace:
• Swansea Bay (by Tidal Lagoon Swansea Bay)
• St. Asaph (by North Wales Tidal Energy & Costal Protection)
As a whole, the UK has the potential for over 11,000 MW, a staggering amount given the relatively small landmass of the country. This makes it the single largest source of hydrokinetic power in Europe, enough theoretically support 10 percent of the world’s energy consumption. Cont'd...
Small-scale solar power growing in the United States
By Daniel J. Graeber for UPI.com: Small-scale solar installations in the United States account for about a third of the overall capacity on the grid, a report from the federal government said.
The U.S. Energy Information Administration estimates total U.S. solar-power output in September, the last full month for which data are available, at 3.5 million megawatt hours. Of that, just more than 30 percent came from small-scale solar installations.
"Generation from roof-top photovoltaic systems has become an increasingly important part of total solar generation in the United States," EIA AdministratorAdam Sieminski said in an emailed statement.
A September report from the Solar Energy Industries Association, with support from green energy market adviser GTM Research, found second quarter residential solar capacity grew 70 percent year-on-year to 473 megawatts. Cont'd...
