Akshat Rathi for Quartz: Renewable electricity is already competitive with fossil-fuel power. Better still, the report makes the extraordinary prediction: By 2020, all forms of renewable electricity will be consistently cheaper than power produced by burning fossil fuels.
Allison Mills for Phys.org: Distributed microgrid tech can secure the electrical grids at military bases to reduce the impact of cyberattacks, physical attacks from terrorists and natural disasters.
Clean energy actions saving companies $3.7 billion a year, cutting annual carbon pollution equivalent to 45 coal-fired power plants
Nichola Groom for Reuters: A year after Congress extended generous tax credits for renewable energy projects, the U.S. wind industry is thriving. Solar power companies, meanwhile, are hunkering down for a rough 2017. The tax credit renewal has boosted the long-term outlooks for both industries. But in the short term, the subsidies are far more attractive for wind power, which has spurred utilities to launch wind projects while they scale back or delay solar installations. Advances in wind turbine technology are also opening up new locations for development and driving a wave of spending to upgrade existing projects. In the last few weeks, power companies with large renewable holdings - including Southern Co, NextEra Energy Inc and Xcel Energy Inc - have announced plans to invest billions of dollars in wind. "We're making a pivot now away from solar," Southern Chief Executive Tom Fanning told a meeting with Wall Street analysts in October. Cont'd...
By Pete Danko for KQED News: In just a few short years, solar power has gotten big in California, and now it’s at the top of the renewable energy heap. Data compiled from daily reports by the state’s major grid manager indicate that in 2015, solar became the No. 1 source of renewable energy in California. Not only did solar beat wind power for the first time, but it also topped drought-depleted hydropower, the long-standing leader in California electricity generation outside fossil fuels and nuclear. The California Independent System Operator doesn’t cover the entire state, but it does manage about 80 percent of the California grid, including those portions served by PG&E, Southern California Edison and San Diego Gas & Electric, the state’s three big investor-owned utilities. Every day, CAISO reports on the hourly electrical output from a long list of sources for the electricity used by 30 million Californians, ranging from biogas at the low end of generation to thermal — natural gas, essentially — at the high end.

By MAYUMI NEGISHI for the WallStreet Journal: Japanese cities are entering the renewable-energy business, the latest phase in a shake-up of the nation’s power sector in the aftermath of the 2011 Fukushima nuclear crisis. So far, about 14 cities have formed companies to generate clean energy from local resources and sell it to area businesses and homes. With full deregulation of the nation’s electricity markets set to begin next year, the government aims to have 1,000 such city-operated companies up and running by 2021 in a direct challenge to regional power monopolies. The move is part of Japan’s strategy for creating energy self-sufficiency, while helping revitalize communities with infrastructure investment. Cont'd...
By Timothy Cama for The Hill: The Obama administration announced Wednesday morning a series of efforts worth more than $120 million aimed at boosting solar and other clean energy sources. The initiatives focus on the Department of Energy, where the bulk of the funding will go to programs to develop solar power technology and get it into homes, businesses and other facilities. “President Obama and Vice President Biden are committed to promoting smart, simple, low-cost technologies to help America transition to cleaner and more distributed energy sources, help households save on their energy bills, and to address climate change,” the White House said in a fact sheet outlining the efforts. “All told, this funding will drive the development of affordable clean energy throughout the country,” it said. The actions aim to help out solar power in 24 states, officials said. Cont'd...

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
