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.

Flooding from Hurricane Florence, which battered the Carolinas this month, is so severe that NASA was able to spot darkened, contaminated rivers flowing into the Atlantic Ocean.

Nearly 8 trillion gallons of rain fell on North Carolina during the storm, according to the National Weather Service in Raleigh. That deluge took a devastating toll, swelling rivers and inundating homes.

NASA satellite images released this week reveal just how engorged, and polluted the rivers and other waterways became.

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.

Intensifying Hurricane Florence Poses Extreme Threat to Southeast and Mid-Atlantic

           

washingtonpost.com - by Brian McNoldy and Jason Samenow - September 9, 2018

 . . . “There is an increasing risk of two life-threatening impacts from Florence: Storm surge at the coast and freshwater flooding from a prolonged heavy rainfall event inland,” the National Hurricane Center wrote Sunday . . . We are particularly concerned about the rainfall potential in the Mid-Atlantic. Models have come into agreement that a northward turn before reaching the United States is unlikely and that a building high-pressure zone north of the storm will cause it to slow or stall once it reaches the coast or shortly thereafter.

Florence could sit over some part of the Mid-Atlantic for several days, similar to what Harvey did last year over eastern Texas. It has the potential to dump unthinkable amounts of rain over a large area in the Mid-Atlantic and perhaps into the Northeast. Rainfall could begin Friday or Saturday and continue into the following week. Where exactly the zone of heaviest rain sets up is a big uncertainty. It could reasonably occur anywhere between the mountains and the coast . . .

Electric Scooters’ Sudden Invasion of American Cities, Explained

           

Turns out there’s a lot of latent demand for a quick and cheap way to get around.

vox.com - by Umair Irfan - August 27, 2018

 . . . Amid the feverish passion for and against scooters, there’s a larger reckoning taking place about rapid changes to our cities and public spaces. The scooters are forcing conversations about who is entitled to use sidewalks, streets, and curbs, and who should pay for their upkeep.

They’re also exposing transit deserts, showing who is and isn’t adequately served by the status quo, and even by newer options like bike share. That people have taken so readily to scooters shows just how much latent demand there is for a quick and cheap way to get around cities.

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).

When Cheap Doesn’t Cut It: Why Energy Buyers Should Look at Value, not Just Cost

submitted by Krae Van Sickle

           

 

Figure 1: Distribution-scale solar costs more than wholesale power, but it costs less if you fairly value all benefits

rmi.org - by Titiaan Palazzi Thomas Koch Blank - May 1, 2018

“New Record Set for World’s Cheapest Solar.” A headline like this makes for great social media fodder. The downward trend in renewables prices is fantastic—it’s the most important driver for the growth of solar and wind energy.

However, when your business or utility is comparing different energy projects, looking at cost alone is not enough. Even energy projects at very low costs can be “out of the money” if the value created by a project is less than its cost.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

           

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

nytimes.com - by JAMES GLANZ and FRANCES ROBLES - Photographs by TODD HEISLER - May 6, 2018

 . . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

 . . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Carbon dioxide — the gas scientists say is most responsible for global warming — reached its highest level in recorded history last month, at 410 parts per million.

This amount is highest in at least the past 800,000 years, according to the Scripps Institute of Oceanography. Prior to the onset of the Industrial Revolution, carbon dioxide levels had fluctuated over the millennia but had never exceeded 300 parts per million.

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.

Wind and Solar Costs Continue to Drop Below Fossil Fuels. What Barriers Remain for a Low-Carbon Grid?

           

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

utilitydive.com - by Michael O'Boyle, Silvio Marcacci - March 21, 2018

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017.  In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.
