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

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).

San Antonio, Texas - CPS Energy Wants Your Input On Their Flexible Path Plan

kens5.com - by Jeremy Baker - June 13, 2018

CPS Energy is holding a public input session Wednesday evening about what they are calling their Flexible Path program, and a look into the future of energy in the Alamo City.

"We currently are going to put a plan together with the involvement of the community, to help reduce the amount of fossil fuels that we have in our generation mix and move more toward renewable energy and more innovative technology," CPS Energy spokesperson John Moreno said.

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.

Microgrids as Resilient Energy Infrastructure

           

Microgrid at Princeton University

utilitydive.com - March 20, 2018

The National Academy of Sciences defines “resilience” as the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events.  Since the September 2017 DOE NOPR to FERC, the energy industry has been working overtime to better define resilience.  FERC unanimously set aside the “90 days on-site fuel storage” provision espoused by DOE and opened a new docket (AD18-7) to more fully examine the current state of grid resiliency, asking the nation’s seven RTO’s and ISO’s to provide their definition of resiliency relative to the bulk power system by March 9.  Those ISO/RTO comments reflected regional variances as expected while sharing a common thread of the paradigm shift underway from central station power plants to more distributed generation . . .

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.

Utilities companies won't let you sell your own solar power. Why not?

The electric utility sector is broken – but the transformation we need will be virtually impossible so long as a handful of wealthy elites are calling the shots

theguardian.com - by Kate Aronoff - August 1, 2017

A new report from the US-based Energy and Policy Institute last week found that investor-owned utilities have known about climate change for nearly 50 years – and done everything in their power to stop governments from doing anything about it.

From their commitment to toxic fuels to their corrosive influence on our democracy to their attempts to price-gouge ratepayers, it’s long past time to bring the reign of privately-owned electric utilities to an end.
