One of the biggest criticisms against wind and solar energy has been quashed

Akshat Rathi for Quartz: Wind and solar energy helped avoid between 3,000 and 12,700 premature deaths in the US between 2007 and 2015.

The Solar Industry Has Paid Off Its Carbon Debts

Robinson Meyer for The Atlantic:  Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world. Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all?  To that concern, a new analysis answers: Yes. The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds.   Cont'd...

World's Largest Carbon-Capture Plant to Open Soon

Umair Irfan for ClimateWire:  On schedule, on budget.  It's a tall order for any new technology, but for a commercial carbon capture and storage (CCS) system, it might be the start of a revolution. The Petra Nova carbon capture system under construction at the W.A. Parish Generating Station, a coal-fired power plant southwest of Houston, is slated to go online before the end of the year. The billion-dollar facility will become the largest post-combustion carbon capture system installed on an existing power plant in the world. Systems like Petra Nova that keep carbon dioxide from reaching the atmosphere may become a necessary means to mitigate climate change, and for some utilities, they could offer a lifeline to beleaguered fossil fuel plants.  Cont'd...

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...

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
