Functioning as the brain of the PV system, advanced inverter solutions are now responsible for communications, monitoring, smart energy management, storage, grid interaction, safety and more.
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.
