The power grid serves as the interstate highways of our electric system. A modern, flexible system for delivering electricity generation over long distances is essential to the nation's successful transition to a clean power future.
The lessons of Solar Impulse are clear: by pushing the boundaries of technology, and refusing to accept limits, technological or psychological, we can run the world without consuming the earth, and reach heights we never believed were possible.
This technique is projected to reduce solar panel manufacturing costs by upwards of 60% compared to industry standards, while making them 25% more efficient, and resulting in a very cost-effective source of energy.
Energy Returned Over Energy Invested - a concept introduced in a paper by Dr John Morgan, which I found in Principia Scientific under the heading The Catch-22 of Energy Storage.
Since clouds, atmosphere and nighttime are absent in space, satellite-based solar panels would be able to capture and transmit substantially more energy than terrestrial solar panels.
With Albermarle's new mine in Nevada and Tesla's forecast 2018 demand of between 25,000 and 35,000 TPA, the U.S. Southwest is becoming a new hotbed for the lithium industry.
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 SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
