Solar Energy Becoming More Predictable Thanks to Forecasting
Ultimately, the use of forecasting allowed the plant operator to send commitments in line with what is required by the grid operator.
Using Silicon in Lithium Ion Batteries to Increase Capacity
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.

Scripps Vessel Proves Viability of Renewable Fuel on 14,400-Mile Voyage
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. Cont'd...
Maintenance and Lubrication of Wind Turbines
Wind turbine gearboxes are challenging to maintain because they are often in remote locations, at elevated heights, and operating under extreme conditions.
SolarCity pushing industry to 40% increase in useful lifetime of solar power installations
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.

What is the Deep Decarbonization Pathway Project?
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.
IKEA of energy delivers clean, green solar power-plant in a box
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. Cont'd...
Are Microgrids Catching On?
The real trick to opening the floodgates on microgrids is clear regulatory language that allows microgrid developers to serve the needs of an organization or community while also making the local electric utility whole for their services and investment.
The "Redox" Principle
The energy density of the nanoFlowcell® is currently 20 times higher than that of a lead accumulator. This means the stored energy provides a range 20 times higher than with a battery of the same weight.
Very Large Lithium-ion Batteries
In the case of the relatively new market for very large, ground-based lithium-ion battery packs for such things as grid peak shaving, weight is not a primary issues, volume can matter somewhat but life, cost over life, performance and reliability matter greatly.
