Renewable Energy Procurement: Trends, Outlook & Strategy
Replacing electricity generated from burning fossil fuels with electricity from wind and solar is a good business strategy
The Aquion Energy Saltwater Storage Battery
This system is working good in a 4000 sq ft shop & house combo, but could use more storage for peace of mind & will likely upgrade next year.
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...
Follow-up: Moving off-the-grid and into a micro-house in the Southern Adirondacks
I would recommend this living situation to anyone! I feel that this isnt just a temporary fad but a trend that will continue especially for Millennials that are buried in debt, specifically student loans.
Flow Batteries in Cars?
Flow battery technology is immature. There is everything to play for and although pumping liquids from reservoirs does not sound compact or reliable in a car but who knows? Watch this space.
Green Data Centers Promote a Clean Future
Companies realize it wont be practical to rely on old forms of energy forever. The sooner they can test and implement new, greener solutions in their data centers, the quicker they can view the future confidently.
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...
Solar & Wind Cheaper To Replace Coal In UK Than Biomass
Joshua S Hill for CleanTechnica: Â A new study has concluded that transitioning to wind and solar power would be a cheaper option for the United Kingdom to replace its coal fleet than using biomass electricity generation.
According to a new study published this week by the Natural Resources Defense Council (NRDC) and conducted by London-based Vivid Economics, which examined the full system costs of renewable energy technologies like wind and solar in comparison to biomass as a replacement for the UKs coal fleet, wind and solar came out as the cheaper option.
The UK already uses a lot of biomass for electricity generation, with the report concluding that "biomass supplies the lions share" of the countrys renewable electricity generation. However, as the authors of the report note:
"…recent science shows that many forms of biomass produce more carbon emissions than fossil fuels like coal and natural gas-especially biomass from forests-increasing carbon pollution precisely when the United Kingdom aims to rapidly decarbonise its electricity sector."  Cont'd...
What is a Stacked Perovskite/CIGS Solar Module?
As this result shows that the combination of two PV technologies can outperform the power generation of single junctions the significance of this result shouldnt be underestimated as it breaks the current limitations of solar technology and shows that higher performing modules can be expected to become part of the energy system ...
