If the solar industry reaches this Department of Energy (DOE) target, it could dramatically alter the energy market and present a future where residential PV becomes a standard, cost-effective home installation, versus a luxury or long-term investment. A recent NREL report — Cost-Reduction Roadmap for Residential Solar Photovoltaics (PV), 2017-2030 — models a set of pathways that the industry could follow to realize this future. The analysis focuses on two key markets for residential PV cost reduction: installing PV at time of roof replacement and installing PV at time of new construction. These two market segments were selected because each offers significant cost reduction opportunities while representing a 30 gigawatt (GW) annual market nationwide (see Figure 1).

Valuing the Resilience Provided by Solar and Battery Energy Storage Systems

submitted by John Cooper

Summary:

Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design. Using data from Southern California Edison, researchers analyzed the economic case for solar+storage for three customer types (school, office building, and hotel) in Anaheim, California. In each case analyzed, larger PV and battery storage systems were found to be economical when the value of resilience is accounted for.

Hurricanes blew away Puerto Rico's power grid. Now solar power is rising to fill the void.

More than three months after Hurricanes Maria and Irma slammed their island, over a million Puerto Ricans are still without reliable power. But one recent day, Rosa López and José Quiñones finally left those ranks.

It happened when four technicians installed a Tesla Powerwall solar battery pack onto a wall in their suburban San Juan home — a 275-pound white metal beast that can store enough electricity to keep a house running from sunset to sunrise.

Costa Rica has charted another clean energy accolade. So far this year, the Central American country has run on 300 days of 100 percent power generation from renewable energy sources, according to the Costa Rican Institute of Electricity (ICE), which cited figures from the National Center for Energy Control. . . .

 . . . Costa Rica currently receives 99.62 percent of its electricity from five renewable sources, the highest proportion since 1987. This year, 78.26 percent of electricity came from hydropower, 10.29 percent from wind, 10.23 percent from geothermal energy and 0.84 percent from biomass and solar. 

Costa Rica has emerged as a global environmental leader, with its frequent 100 percent renewable energy streaks and its 2021 goal of becoming carbon neutral—a deadline set a decade ago.

Puerto Rico Energy Commission Opens Docket on Microgrids and Distributed Generation

Puerto Rico Gov. Ricardo Rosselló Nevares testifying on Capitol Hill this week.

microgridknowledge.com - by Elisa Wood - November 17, 2017

Puerto Rico’s energy commission has opened a docket to investigate ways to encourage microgrids and distributed generation to build an energy system with more fortitude against hurricanes.

Island officials described the docket this week in testimony before the U.S. Senate Committee on Energy and Natural Resources. Half of the island’s population remains without power two months after Hurricane Maria’s strike.

Puerto Rico's Storm of Misery

       
 
Devastation in Puerto Rico - CBS News
 
cbsnews.com - by Steve Kroft - November 5, 2017
 
Many Puerto Ricans have endured the longest blackout in American history following a direct hit from Hurricane Maria. Due to a multitude of factors, some say the lights won't be coming back on anytime soon.
 
It's safe to say that of all the places in the country, the one that is suffering the most right now is the hurricane-ravaged island of Puerto Rico . . . For the past 46 days, most of them have been without power, the longest blackout in American history. FEMA says it has distributed more food and water there than any disaster its ever been involved in.

[VIDEO] Prime Minister Skerrit to UN General Assembly: “Eden is broken”

dominicanewsonline.com - September 23, 2017

In words ripe with emotion lamenting that “Eden is broken”, Dominca’s Prime Minister Roosevelt Skerrit addressed the UN General Assembly this morning, seemingly intent on drawing the world’s attention to current conditions in Dominica in what he described as a landscape resembling a war zone.

The image he evoked was in direct support of his plea to fellow world leaders to assist the hurricane-ravaged island by lending the rebuilding equipment which would otherwise remain untouched “waiting for a war” and which is so desperately needed for the work of rebuilding the country. Roosevelt asserted that Dominica is indeed that war, to the applause of the floor.
