Pittsburgh's Microgrids Technology Could Lead The Way For Green Energy

           

Gene Lutz drives an electric fork lift powered by renewable energy at Pitt Ohio, a trucking company with an office in Harmar, Pa. The firm has invested in solar and wind energy, along with a bank of storage batteries, to create an independent microgrid that would hold up in a storm. Researchers hope to build more of these and link them together to create a reliable backup supply.  Daniella Cheslow/NPR

When President Donald Trump announced the U.S. would withdraw from the Paris climate accord, he said he represented "Pittsburgh, not Paris."

Pittsburgh Mayor Bill Peduto disagreed. He traveled to Germany this week as part of an unofficial delegation of more than 100 Americans, American officials and business owners who say they are still committed to climate talks taking place in Bonn. One element of Pittsburgh's climate strategy has been encouraging innovation in a technology known as microgrids.

The primary transmission lines that criss-cross Puerto Rico are steadily coming back online following Hurricane Maria, with several different contractors responsible for bringing back power.  The island lost all of its power after the storm; it still has a goal to restore 95 percent of power by the middle of December.

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.

San Juan, Puerto Rico

Seven weeks after hurricane Maria, the traffic lights are still down in San Juan. The narrow, cobbled streets of the city’s historic center, one of the island’s top tourist attractions, turn pitch black as soon as the sun sets. With appliances useless during the blackout, many of the city’s residents can’t cook, store food, or take a real shower.

SAN JUAN, P.R. — A main power line that serves the northern half of Puerto Rico failed Thursday, knocking out electricity to seven cities that had only recently regained service and dealing a major setback to the island’s desperate efforts to regain normality.

Seven weeks after Hurricane Maria completely disabled Puerto Rico’s power grid, the island was generating just 18 percent of its electrical capacity, returning service to where it had been two and half weeks ago. On Thursday morning, the island had been at about 43.2 percent of capacity.

The disruption also me ant that many people no longer had running water, because pumping stations are powered by electricity.

Puerto Rico's Storm of Misery

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.

wired.com - Adam Rogers - October 10th 2017

Nearly three weeks after Hurricane Maria tore through the Caribbean, Puerto Rico is still mostly an island deleted from the present and pushed back a century or so—with little clean water, little electric power, and almost no telecommunications. For telecom, the biggest problem is the lack of power, because most of the island’s transmission lines were knocked out. “We have to reconstruct the power grid as if we were dropping into the middle of the desert and starting from scratch,” says Luis Romero, vice president of the Puerto Rico Telecommunications Alliance.

Hurricane Maria: Dominica Aerial Pictures Show ‘Total Destruction’

nbcnews.com - by Yuliya Talmazan - September 20, 2017

Dominica's main hospital "took a beating" from Hurricane Maria while buildings serving as shelters had their roofs ripped off, an official said as the first images showing the devastation unleashed by the storm emerged Wednesday.

The Category 5 storm hit the tiny Caribbean island late Monday, cutting off communications and leaving the rest of the world in the dark about the storm’s aftermath.

Video footage shot by the Caribbean Disaster Emergency Management Agency shows large swaths of the island suffered heavy damage, with roofs missing and debris scattered for hundreds of yards.
