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...
Tesla powers a whole island with solar to show off its energy chops
James Vincent for The Verge: Tesla completed its $2.6 billion acquisition of SolarCity this week, and, to celebrate, the company has announced a major solar energy project: wiring up the whole island of Ta’u in American Samoa. Previously, the island ran on diesel generators, but over the past year Tesla has installed a microgrid of solar energy panels and batteries that will supply "nearly 100 percent" of power needs for Ta’u’s 600 residents.
The project seems intended to show off the potential benefits of the SolarCity acquisition, with Ta’u’s microgrid comprised of 5,328 solar panels from SolarCity and Tesla, along with 60 Tesla Powerpacks batteries for storage. But buying SolarCity remains a risky move for Tesla, with the purchase including billions of dollars of debt for a company that's far from profitable (SolarCity spends $6 for every $1 it makes in sales). Nevertheless, Tesla CEO Elon Musk describes the acquisition as "blindingly obvious" — a necessary step in his so-called "Master Plan" to integrate clean energy generation and storage. Cont'd...
Power to the people: Solar panel sales to soon surpass leasing
Lucas Mearian for ComputerWorld:  Direct ownership of solar power panels will overtake third-party ownership next year as more consumers are choosing to buy, rather than lease, their panels.
According to GTM Research's latest report, U.S. Residential Solar Financing 2016-2021, 55% of all U.S. residential solar capacity installed in 2017 will be purchased by customers paying either in cash, or through a solar loan financing arrangement; that number is expected to grow to 73% of all solar systems installed in 2021.  Cont'd...
Want to boost wind and solar power? Bring them together
Ben Jervey for GreenBiz: What’s keeping solar and wind power from fully taking over the electric grid? For starters, the sun only shines during the day. Wind blows intermittently, is seasonally variable, and is not always blowing when the energy is needed.
But what if solar and wind work together? "Wind resource tends to complement solar resource," said Sarah Kurtz of the U.S. Department of Energy’s National Renewable Energy Laboratory. "Here in Colorado, for instance, the windiest time is during the winter and spring months. In winter, we don’t have as much sunshine, but we tend to get more wind and stronger wind."
A handful of enterprising renewable energy developers are exploring how solar and wind might better work together, developing hybrid solar-wind projects to take advantage of the power-generating strengths of each — with the two technologies in tandem serving as a better replacement for climate-warming fossil fuels than either could be alone.

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 Meets Electric Vehicle Atop a VW Microbus
Brett Belan, Apparent Energy for MotherEarth News: The time is here for solar power to make its way to our vehicles. The state-of-the-art panels pose no weight limitation. At 6 pounds per 150 watts, thin flexible solar panels will weigh 600 pounds but give you 15 kilowatts! This is enough to directly drive from the sun.
However, the surface area is a limitation, because that much solar would require 10 feet around the vehicle on all sides. The solution, ironically, is a mechanical engineering question of how to accordion-style fold these panels to conveniently open them for charging while the vehicle is at a standstill. 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...
Batteries That Make Use of Solar Power, Even in the Dark
Stanley Reed for the NY Times: A new cash crop has sprung up on Nicholas Beatty’s enchanting farm near here. Rows of gray solar panels range over about 25 acres, turning sunlight into electricity, as dog-size muntjac deer hop by.
The panels themselves, trouble-free money earners that feed into the electric grid, are no longer unusual on farms in Britain or other countries. What’s new in Mr. Beatty’s field is a hulking 40-foot-long shipping container.
Stacked inside, in what look like drawers, are about 200 lithium-ion cells that make up a battery large enough to store a substantial portion of the electricity the solar farm puts out.
The battery and its software give Mr. Beatty an advantage over other solar panel farmers. Power prices in Britain and elsewhere rise and fall, sometimes strikingly, during the day and over the year, depending on the supply and demand. Cont'd...
New York set for offshore wind after environmental review
Daniel J. Graeber fro UPI: Areas off the New York coast will be open for offshore wind energy bidders, but some area is reserved because of ecological concerns, the U.S. government said.
The U.S. Interior Department, in coordination with its Bureau of Ocean Energy Management, said it would open 79,350 acres off the coast of New York up for a commercial wind energy lease sale. About 1,780 acres was removed because of environmental concerns associated with a subsea feature known as the Cholera Bank.
"In a comment letter, the National Marine Fisheries Service identified the Cholera Bank feature as a sensitive habitat to be avoided for the placement of structures," an Interior Department stated read. "As a result of this removal, the revised lease area will be approximately two percent smaller than the lease area considered in the proposed sale notice." Cont'd...
Elon Musk wants to sell you a better-looking solar roof amid slowing growth for panels
Ivan Penn and Russ Mitchell for The LA Times: Like some kind of 21st century Willy Wonka, audacious entrepreneur Elon Muskchose a prime spot on the Universal Studios Hollywood backlot tour to unveil his latest attempt to energize an industry — roofs that generate solar power but look like no other.
Musk, the chief executive of Tesla Motors and chairman of SolarCity, showcased a line of high-design solar roof tiles that would replace clunky solar panels and tie into an upgraded version of the Tesla wall-mounted battery for those times when the sun doesn’t shine. The glass solar shingles resemble French slate, Tuscan barrel tile or more conventional roofing materials with a textured or smooth surface.
“The key is to make solar look good,” Musk said during the product introduction staged on the old set of ABC’s “Desperate Housewives” series, where he had re-roofed four of the Wisteria Lane houses. “If this is done right, all roofs will have solar.” Cont'd..
Half a million solar panels were installed every day in 2015.
Katie Herzog for GRIST: Half a million solar panels were installed every day in 2015. According to a new report from the International Energy Agency (IEA), renewable energy, mostly solar and wind, accounted for more than half of all new electric capacity added in the world last year, a 15 percent jump from 2014. Globally, there is now more renewable power capacity than coal power capacity.
Clean energy growth was especially high in China, which was responsible for about 40 percent of all new clean energy capacity. Get this: In China in 2015, two wind turbines were installed every hour.
This surge in renewables, according to the IEA, can be attributed to policy changes, lowered costs, and improvements in technology. Cont'd...
Bike Path In Poland Can Glow For 20 Years Using Solar Power
Andrew Conrad for PSFK: It’s no Yellow Brick Road, but residents of Olsztyn, a town along the Lyna River in northern Poland, can now follow along this glowing bike path to travel safely to their destination. Using solar power, it is said that the path can remain illuminated for up to 20 years.
The engineering breakthrough, developed by Polish firm TPA, was unveiled in late September as a 100-meter trial section with plans for expansion. The asphalt in the path is blended with particles that absorb energy from the sun during daylight hours and then glow for up to 10 hours once the sun goes down. The plan is to increase the shorter section following winter. Cont'd...
Europe's offshore wind industry booming as costs fall
The Guardian: On a sunny October morning, our boat passes the run-down relicts of Liverpool’s maritime past and heads down the river Mersey and into the Irish Sea. As we steam offshore, I see in the distance a cluster of tall structures that soon reveal themselves to be towers of a wind turbine array. Arriving at the windfarm, six miles offshore, the turbines rise as high as 650ft, taller than the tallest church in the world. Each of the turbines’ three shiny metallic rotor blades is nearly 300ft long.
“A single rotation of an eight-megawatt turbine will cover the daily electricity consumption of an average British household,” says Benj Sykes, vice president of Dong Energy Wind Power, the company that is constructing and co-owns this wind project, as the boat rocks in five-foot swells. Cont'd...
Idaho company debuts solar power sidewalks
Nicholas K. Geranios for AP: Scott Brusaw has a vision for the nation's roads.
He believes the solar-powered glass pavers his company makes could transform thousands of miles of pavement into a new energy source.
His business, Solar Roadways, recently unveiled its first public installation, in a downtown plaza in this northern Idaho resort town. It's 150 square feet of hexagon-shaped solar panels that people can walk and bicycle on.
The company is working on proof that the panels, for which it has a patent, are strong enough and have enough traction to handle motor vehicles, including semitrailers.
"Our plan is to replace all the asphalt and concrete," said Brusaw, noting concrete occupies over 48,000 square miles in the U.S. "If you cover it with solar panels, we can make three times our energy needs."
Solar Roadways is among a growing number of companies embracing renewable energy as the U.S. aims to reduce carbon emissions by one-third from 2005 levels by 2030. Cont'd...
