In trial run for hurricane season, South Miami’s solar-powered mayor went off the grid

           

Solar panels on the roof of South Miami Mayor Philip Stoddard’s energy-efficient home in South Miami on Saturday, April 13, 2019. Stoddard went off the grid for seven days to test the house’s readiness for hurricane season and used only solar panels and two Tesla wall batteries to power his home. Daniel A. Varela ***@***.***

Hurricane season is coming and Philip Stoddard is ready . . .

. . . Stoddard, a champion of solar energy and green living, took his family on a trial run in preparation for the next Irma or Andrew . . .

. . . He turned off the main power switch located in a panel on the side of his house . . . For the next seven days, he and his family were able to operate the central air-conditioning unit during an unseasonably hot March week, all appliances, computers, lights, TV, solar water heater with an electric on-demand booster, and backyard pond pump, and charge the car without once running out of juice.

How to Cut U.S. Emissions Faster? Do What These Countries Are Doing.

           

nytimes.com - by Brad Plumer and Blacki Migliozzi - February 13, 2019

The United States is reducing its greenhouse gas emissions far too slowly to help avert the worst effects of global warming. But what would happen if the country adopted seven of the most ambitious climate policies already in place around the world?

1)  adopt an economy-wide carbon tax similar to British Columbia’s

2)  require utilities to produce all their electricity from zero-carbon sources

3)  encourage aggressive electric-vehicle incentives similar to Norway’s

4)  set efficiency targets for industries

5)  set energy efficiency standards for new homes and commercial buildings

6)  curb methane emissions from oil and gas operations

7)  adopt legislation to end the use of hydrofluorocarbons similar to the European Union’s

pv-magazine-usa.com - by Christian Roselund - February 7, 2019

PREPA’s draft IRP calls for rapid deployment of solar and batteries, including the installation of as much battery storage as is currently online in the entire United States over the next four years, in a system broken up into “minigrids”. However, it stops short of utilizing behind-the-meter PV and storage . . .

 . . . PREPA’s final IRP is scheduled to be published on February 12.

Will Solar Panels Survive a Nuclear Electromagnetic Pulse (EMP)?

           

CLICK HERE - Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack - Volume 1: Executive Report - 2004 (62 page .PDF report)

solarpowerrocks.com - by Ben Zientara - October 2017

. . . The thing to be worried about here is what’s known as a nuclear electromagnetic pulse, or EMP for short. If a nuclear weapon of sufficient size is detonated, an EMP can disrupt everything that uses electronic circuitry, potentially causing irreversible damage to electronics in cars, airplanes, the U.S. electric grid, and yes, your home solar system . . .

. . . the U.S. Government has commissioned a few studies of the effects and likely aftereffects of an EMP-as-weapon deployed against the country . . .

. . . Coronal Mass Ejections (CME) . . . it’s a lot like the E3 component of a nuclear EMP, and can shut down the grid in much the same way.

How a ‘Solar Battery’ Could Bring Electricity to Rural Areas

theverge.com - by Angela Chen - September 27, 2018

Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.

The problem of energy storage has led to many creative solutions, like giant batteries. For a paper published today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

Solar Installers Should Bundle Panels With Heat Pumps, Study Says

           

Solar installers could make a better business case for panels bundled with heat pumps and other electric devices that offset natural-gas use, according to the Rocky Mountain Institute.

Solar installers could offer rooftop customers even more savings by bundling solar panels with heat pumps and other electric appliances, according to a recent study by the Rocky Mountain Institute.

RMI studied the carbon benefits and financial costs  of electrification of home heating in four U.S. cities. The carbon reductions were pronounced in three of the four. The financial costs were harder to overcome—unless the electricity comes not from the grid, but from the rooftop.

Solar on Every Home? NREL Outlines Pathways to Ultra Low-Cost Residential Solar

sepapower.org - by Jeffrey Cook - August 16, 2018

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).

A Dramatic New Proposal in Utility Regulation

       

DC just proposed a first-of-its-kind regulatory body—and utilities should pay close attention.

CLICK HERE - Joint Release: Councilmembers Allen and Cheh to introduce bill modernizing DC’s energy grid

icf.com - by Steve Fine and Matt Robison - April 17, 2018

Two Washington, D.C. City Council members proposed a remarkable change in utility regulation last week. Mary Cheh and Charles Allen introduced a bill to create a Distributed Energy Resource Authority (DER Authority): a first-of-its-kind regulatory body that would be empowered to undertake traditional utility planning functions, and with a specific mandate to assess any proposed utility grid investment greater than $25 million and open it up to competitive bids.

Companies face world where falling cost of solar and wind power pushes down prices

theguardian.com - by Adam Vaughan - March 17, 2018

Seven years after an earthquake off Japan’s eastern coast led to three meltdowns at the Fukushima Daiichi nuclear power station, the aftershocks are still being felt across the world. The latest came last Saturday when E.ON and RWE announced a huge shakeup of the German energy industry, following meetings that ran into the early hours.

Tired of Waiting for Electricity in Puerto Rico, Man Builds His Own Solar Power System

           

Frank says his experience with electrical work helped him tackle the solar panel installation.

cnn.com - by Paul P. Murphy - April 19, 2018

Another day, another blackout in Puerto Rico; Wednesday's blackout was the latest to hit the island still recovering from Hurricane Maria. But one man beat the power outages and his troublesome gas generator by switching to solar power.

"As I'm typing this, we are in the middle of a blackout and my fridge, lights and fans are running worry free," a man named Frank told CNN.
