Timothy Cama for The Hill: The Obama administration is making a new large-scale effort to encourage deployment and use of rooftop solar power on homes. Numerous agencies announced new or strengthened coordinated efforts Tuesday aimed at increasing solar installations in houses owned by low- and moderate-income Americans, including a new goal for solar installations and a policy change to increase access to a key financing mechanism for solar power and energy efficiency. “This is an approach that cuts across the government to try to take advantage of the fact that the cost of renewable technologies has come down dramatically during President Obama’s tenure, and we want to advantage of that a try to encourage more homeowners to actually benefit directly from that dynamic,” Brian Deese, a top adviser to Obama, told reporters. The administration is dubbing the effort the “Clean Energy for All Americans Initiative.” Cont'd...
Investment slowdowns in China and Japan, as well as further reduction in the cost of solar, mean 2016 investment will fall well short of 2015's upwardly revised $348.5bn
Investors will need to understand the differences between on-grid and off-grid solar. And a long term proof of bankability of the off-grid solar sector is still needed.
Ultimately, the use of forecasting allowed the plant operator to send commitments in line with what is required by the grid operator.
A key attribute of silicon in lithium ion batteries (LIB) is the higher capacity that Si can offer which leads to greater electric vehicle driving range or longer operating consumer electronics.
Achieving engagement with a customer is about meaningful interaction with the consumer.
Chris Jennewein for Times of San Diego: A Scripps Institution of Oceanography research vessel has demonstrated the viability of renewable fuel by traveling 14,400 nautical miles over a 16-month period on renewable diesel. The R/V Robert Gordon Sproul used a hydrogenation-derived renewable fuel called NEXBTL Renewable Diesel developed by Neste Oil in Finland. The experiment began in September 2014 and ran through December 2015, during which time the vessel used a total of 52,500 gallons. “Part of the Scripps mission is to protect the environment, and one of the most significant changes that we could make in our ship operations involved moving toward the use of cleaner, renewable fuels,” said Scripps Associate Director Bruce Appelgate. “As scientists, we know we need to develop sustainable means of powering our ships to address pollution concerns as well as to mitigate future increases in fossil fuel costs.” Renewable biofuel is nearly carbon-neutral and produces cleaner emissions, thus decreasing greenhouse gas emissions and improving air quality relative to fuels derived from petroleum.

Wind turbine gearboxes are challenging to maintain because they are often in remote locations, at elevated heights, and operating under extreme conditions.
John Fitzgerald Weaver for Electrek: In a new report released by SolarCity, we are seeing that solar power systems have a usable lifetime of at least 35 years – 40% longer than the market expects. The key finding of the report is that power degradation (annual efficiency loss) of solar panels supplied to SolarCity is as much as 35% lower than for a comparable industry-wide selection of non-SolarCity panels, which are typically expected to last for 25 years. SolarCity feels it is the implementation of a stringent and industry-leading “Total Quality Program” that has driven this. SolarCity is in the unique position of being one of the largest deployers of solar panels – from multiple manufacturers – in the world, and with their tens of thousands of systems connected to a central database they know realtime performance. In the study here, SolarCity looked at greater than 11,000 panels to determine their data points and come to their conclusion that their solar panels are performing well beyond expected industry standards.

The challenge for management is to become comfortable with being uncomfortable handling the speed, ambiguity and scary portions of the business rollercoaster.
Laboratory testing of the company's novel prototype cathode material have yielded a set of critical data that translates into significant lithium-ion battery performance projections for BioSolar to target.
Through the consensus-based roadmapping process, the SMART Wind Consortium has linked together more than 2 dozen distributed wind energy equipment manufacturers
Net metering SRO 892(1) 2015 is excellent Order and It should be implemented as early as possible.
The Deep Decarbonization Pathway Project (DDPP) is a global collaboration of energy research teams from around the world, charting practical pathways to deeply reduce greenhouse emissions.
Richard Kemeny for New Scientist: Here’s a bright idea for flat-packing. A German start-up has figured out how to cram an entire solar power plant into a shipping container. It has sent its first kits to off-grid villages in Africa, where they provide a new source of clean, affordable electricity after just two hours of assembly. More than 620 million people in sub-Saharan Africa have no access to electricity, a situation that can keep people in poverty. And population growth means this number is rising. Those with access tend to rely on inefficient diesel generators, chugging along with crippling financial and environmental costs. Despite that, diesel is standard for off-grid energy. “If there’s no diesel, there’s no electricity”, says Rolf Kersten of the start-up, Africa GreenTec in Hainburg, Germany, which shipped its first solar generator to Mali in December last year.

The most compact versatile rail-less PV mounting system under the sun. Instead of placing solar panels on top of long rails, simply attach E Mount AIR to rafters or the roof decking. Once panels are fastened to the roof, the system array is electrically bonded. The result is a visually seamless PV installation that stands the test of time. - Truly "One With The Roof". - PE stamped cert. letters available, UL 2703 Classified, ASTM 2140 fully waterproof. The one and only with integrated flexible flashing certified by the ICC! All the best quality. Only from Roof Tech
