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.

How do you get healthy food on the table when you can't find any?

This is a question that Ortilia Lujan Flores had grappled with many times before.

She wanted affordable, nutritious food, but lived in a neighborhood that didn’t have an accessible grocery store.

Flores couldn't drive, which limited the few food options she had. "There was nowhere to go," she explains.

Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.

Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air.

Resilience Hubs White Paper - Shifting Power to Communities and Increasing Community Capacity

CLICK HERE - Resilience Hubs White Paper - Shifting Power to Communities and Increasing Community Capacity (10 page .PDF document)

usdn.org

Summary

Resilience Hubs are community-serving facilities augmented to:

1.  support residents and

2.  coordinate resource distribution and services before, during, or after a natural hazard event.

They leverage established, trusted, and community-managed facilities that are used year-round as neighborhood centers for community-building activities. Designed well, Resilience Hubs can equitably enhance community resilience while reducing GHG emissions and improving local quality of life. They are a smart local investment with the potential to reduce burden on local emergency response teams, improve access to health improvement initiatives, foster greater community cohesion, and increase the effectiveness of community-centered institutions and programs.

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.

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).

SunSmart Emergency Shelters Program

           

DeSoto Elementary School in Tampa, Florida.

cleanenergygroup.org - Multiple Locations, Florida

Beginning in 2012, in an effort coordinated by University of Central Florida’s (UCF’s) Florida Solar Energy Center in collaboration with the Florida Office of Energy, Florida’s SunSmart E-Shelter Program has equipped more than 100 public schools with small PV systems and batteries, which are sufficient to keep lights and electrical outlets operating during a grid-disrupting natural disaster.  This enables these schools to serve as self-powered places of refuge for communities across the state, providing emergency shelter for 100-500 people per site.
