Michael Kanellos for Forbes: The optimism in the energy storage industry is based on soaring demand, rapid technological advances, expanding capacity and, for some, what will likely be a scary competitive environment.
First, the good news. Lithium ion battery packs over the last ten years have declined faster than the cost of solar, said John Carrington, CEO of Stem, which makes behind-the-meter storage systems for hotels and other commercial customers looking to shave peak power costs, during a hallway meeting at Finance West sponsored by the American Council of Renewable Energy this week.
Solar panels have declined by 50% or more in the last five years. Batteries have declined by 80% in three years, he said. Battery packs hit the under $300 per kilowatt hour mark last December, Carrington added. By 2020, battery pack prices could drop to $190 per kilowatt hour. (In 2007, lithium ion battery packs in the wholesale markets sold for around $1,000 per kilowatt hour.) Cont'd...
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...
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...
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..
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...
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...
