Solar Could Beat Coal to Become the Cheapest Power on Earth
Jessica Shankleman and Chris Martin for Bloomberg: Solar power is now cheaper than coal in some parts of the world. In less than a decade, it’s likely to be the lowest-cost option almost everywhere.
In 2016, countries from Chile to the United Arab Emirates broke records with deals to generate electricity from sunshine for less than 3 cents a kilowatt-hour, half the average global cost of coal power. Now, Saudi Arabia, Jordan and Mexico are planning auctions and tenders for this year, aiming to drop prices even further. Taking advantage: Companies such as Italy’s Enel SpA and Dublin’s Mainstream Renewable Power, who gained experienced in Europe and now seek new markets abroad as subsidies dry up at home.
Since 2009, solar prices are down 62 percent, with every part of the supply chain trimming costs. That’s help cut risk premiums on bank loans, and pushed manufacturing capacity to record levels. By 2025, solar may be cheaper than using coal on average globally, according to Bloomberg New Energy Finance. Cont'd...
China to plow $361 billion into renewable fuel by 2020
Reuters: China will plow 2.5 trillion yuan ($361 billion) into renewable power generation by 2020, the country's energy agency said on Thursday, as the world's largest energy market continues to shift away from dirty coal power towards cleaner fuels.
The investment will create over 13 million jobs in the sector, the National Energy Administration (NEA) said in a blueprint document that lays out its plan to develop the nation's energy sector during the five-year 2016 to 2020 period.
The NEA said installed renewable power capacity including wind, hydro, solar and nuclear power will contribute to about half of new electricity generation by 2020.
The agency did not disclose more details on where the funds, which equate to about $72 billion each year, would be spent.
Still, the investment reflects Beijing's continued focus on curbing the use of fossil fuels, which have fostered the country's economic growth over the past decade, as it ramps up its war on pollution. Cont'd...
Giant Wind Turbines Now At Eight Megawatts, And Getting Larger
Peter Kelly-Detwiler for Forbes: News arrived in late December from the waters off the United Kingdom that the first of MHI Vestas (a joint venture between Vests and Mitsubishi Heavy Industries) 8.0 megawatt (MW) turbines is now delivering commercial power to Dong Energy’s Burbo Bank Extension. The entire 258 MW project – to be completed in Q1 of 2017 - will need only 32 such turbines. This is a significant milestone, as wind turbines have become increasingly more powerful over a relatively short timeframe. This 8 MW machine is currently the largest commercial turbine in the world. Less than ten years ago, at the original Burbo Bank project, a 3.6 MW turbine was inaugurated, the largest in the industry at the time. Cont'd.. .
Swiss Firm to Use Solar Power for Space Tourism
Financial Tribune: SolarStratos, a Swiss startup, has unveiled an airplane that uses solar power to lift people to the edge of space and return them gently to earth.
The company revealed its “solar plane”, a 28 foot-long aircraft that will be the first manned aircraft entirely powered by solar energy to rise above the stratosphere and bring passengers close to the stars. The solar power airplane has a wingspan of 81.3 feet and weighs 992 pounds.
It will take two hours to ascend to the edge of space some 15 miles above the earth. SolarStratos will stay there for 15 minutes before beginning a three-hour descent back to earth. Cont'd...
World's first solar panel road opens in Normandy village
Kim Willsher for The Guardian: France has opened what it claims to be the world’s first solar panel road, in a Normandy village.
A 1km (0.6-mile) route in the small village of Tourouvre-au-Perche covered with 2,800 sq m of electricity-generating panels, was inaugurated on Thursday by the ecology minister, Ségolène Royal.
It cost €5m (£4.2m) to construct and will be used by about 2,000 motorists a day during a two-year test period to establish if it can generate enough energy to power street lighting in the village of 3,400 residents.
In 2014, a solar-powered cycle path opened in Krommenie in the Netherlands and, despite teething problems, has generated 3,000kWh of energy – enough to power an average family home for a year. The cost of building the cycle path, however, could have paid for 520,000kWh. Cont'd...
U.S. wind power enjoys a rebirth as solar's obstacles mount
Nichola Groom for Reuters: A year after Congress extended generous tax credits for renewable energy projects, the U.S. wind industry is thriving.
Solar power companies, meanwhile, are hunkering down for a rough 2017.
The tax credit renewal has boosted the long-term outlooks for both industries. But in the short term, the subsidies are far more attractive for wind power, which has spurred utilities to launch wind projects while they scale back or delay solar installations.
Advances in wind turbine technology are also opening up new locations for development and driving a wave of spending to upgrade existing projects.
In the last few weeks, power companies with large renewable holdings - including Southern Co, NextEra Energy Inc and Xcel Energy Inc - have announced plans to invest billions of dollars in wind.
"We're making a pivot now away from solar," Southern Chief Executive Tom Fanning told a meeting with Wall Street analysts in October. Cont'd...
The Solar Industry Has Paid Off Its Carbon Debts
Robinson Meyer for The Atlantic: Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world.
Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all? To that concern, a new analysis answers: Yes.
The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds. Cont'd...
Nearly half of residential distributed solar power is owned by private companies
Lucas Mearian for ComputerWorld: About 44% of all solar power that's installed on residential rooftops, known as distributed solar capacity, is owned by private businesses, such as SolarCity or Vivint Solar, according to new government data.
Distributed solar capacity in the U.S., which includes all solar power capacity other than utility-scale installations 1 megawatts (MW) or larger, increased to 12.3 gigawatts (GW) as of September, according to new figures from the Energy Information Administration (EIA). In comparison, a cumulative 11.6GW had been installed in the U.S. by the end of 2015. Cont'd...
Glow-in-the-dark dye could fuel liquid-based batteries
Charlotte Hsu for University of Buffalo: BUFFALO, N.Y. — Could a glow-in-the-dark dye be the next advancement in energy storage technology? Scientists at the University at Buffalo think so.
They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes. BODIPY — short for boron-dipyrromethene — shines brightly in the dark under a black light.
But the traits that facilitate energy storage are less visible. According to new research, the dye has unusual chemical properties that enable it to excel at two key tasks: storing electrons and participating in electron transfer. Batteries must perform these functions to save and deliver energy, and BODIPY is very good at them. In experiments, a BODIPY-based test battery operated efficiently and with longevity, running well after researchers drained and recharged it 100 times. Cont'd...
DOE energy innovation hub backs two key future battery technologies
Nick Flaherty for EE Times: After four years of evaluation, the Joint Center for Energy Storage Research (Chicago, IL) is backing two key technologies for the future of battery systems.
The Center was set up four years ago with a five year remit to explore new battery technology for transportation and the electricity grid that, when scaled to commercial production, are capable of delivering five times the energy density at one-fifth the cost of commercial batteries available in 2011.
The Center has investigated 1,500 compounds for electrodes and 21,000 organic molecules relevant for liquid electrolytes as well as filing 52 invention disclosures and 27 patent applications, says director George Crabtree. Five techno-economic models created by JCESR for designing virtual batteries on the computer are being used to evaluate the best pathways for beyond-lithium-ion systems to reach 400 watt hours per kilogram (400 Wh/kg) and $100 per kilowatt hour ($100/kWh).

The World's Largest Solar Plant Is Now Online in India
Avery Thompson for Popular Mechanics: The world's largest solar power plant has just been completed in Kamuthi, in Tamil Nadu, India. The new plant adds 648 MW to the country's generating capacity.
The Kamuthi Solar Power Project takes the title of world's largest solar plant from the Topaz Solar Farm in California, which was completed two years ago and has a capacity of 550 MW.
The Kamuthi Solar Power Project was built in only 8 months, and cost $679 million to complete. It contains 2.5 million individual solar panels, covers an area of almost 4 square miles, and is expected to power 150,000 homes. Cont'd...
Could depleted oil wells be the next step in energy storage?
Power-Technology.com - Quidnet Energy is hoping to revolutionise energy storage with its underground pumped hydro concept, which uses abandoned oil and gas wells to store and release pressurised water, driving turbines and feeding electricity back into the grid. How does the concept work and how far could it go? Quidnet co-founder Aaron Mandell explains.
As the cost of renewable energy continues to decline and intermittent clean power sources such as wind and solar gain ever an ever larger foothold in the global energy mix, the ability to store energy that can be quickly dispatched when needed has become as important as the development of renewables themselves.
Robust storage options could allow for greater integration of intermittent renewables, as they facilitate flexible capacity-building that relies far less on coal and gas-fired plants for baseload generation, meaning energy storage is a key step in the journey to wean the world off its fossil fuel addiction.

The First Tidal Generator in North America Is Now Online
Avery Thompson for Popular Mechanics: The first tidal generator in North America has gone online this month in the Bay of Fundy, and is expected to generate enough electricity to power 500 homes.
While most hydro generators harness the energy of falling water, or the energy of the waves, tidal power uses the energy of the high and low tides. At the Bay of Fundy in Nova Scotia, which has the largest tides in the world, that energy is being harnessed to generate 2 megawatts of electrical power.
In the Bay of Fundy, the difference between high and low tide is about 56 feet. Approximately 115 billion tons of water flow in and out of the bay every tidal period. Two renewable energy developers, OpenHydro and Emera, decided to build turbines on the seafloor that could harness that power. Cont'd...
Solar Power Turns Water and Carbon Dioxide Into Fuel
Seeker: Finish researchers are building a demonstration power plant that would use solar-generated electricity, water and carbon dioxide extracted from the atmosphere to create gas and liquid fuels.
The Lappeenranta University of Technology and VTT Technical Research Centre are working together on the SOLETAIR project, which is being built on the university campus and is scheduled for completion in 2017. Germany's Karlsruhe Institute of Technology also is a player in the project. The project involves several different innovations. VTT will design equipment that will capture CO2 from the air and store it, while Lappeenranta researchers will build a device to produce hydrogen from water via electrolysis. Karlsruhe has developed a a microstructured, chemical reactor to convert the hydrogen produced from solar power together with carbon dioxide into liquid fuels, according to a press release. The reactor will be built by INERATEC, a spinoff company created by Karlsruhe. Cont'd...
Solar power proponents hopeful Trump sees benefit of growing industry
Ivan Penn and Rob Nikolewski for The LA Times: Longtime solar executive Barry Cinnamon got up Wednesday wondering what a Donald Trump administration will mean for his industry.
“I woke up this morning and walked to my car and took a picture of the sun coming up, and it did indeed come up,” said Cinnamon, president of Cinnamon Solar, one of the highest-profile solar companies in Silicon Valley.
Candidate Trump said a lot of things that heartened conventional oil and natural gas producers and worried the renewable energy business, which is growing fast but is still a tiny part of the energy landscape. Cont'd...
