Despite aspen’s ability to grow from the northernmost reaches of Canada to the highest altitudes in Mexico, the tree is on the run. The southern part of the aspen’s range is drying up, while the northern edges are warming up and thus becoming more conducive to the tree’s survival, because of climate change, said Justine Karst, the NSERC Industrial Research Chair in Terrestrial Restoration Ecology.
And while the shrinking, expanding or shifting of a tree’s habitat is always cause for concern, Karst said the bigger questions surround what then happens to one of nature’s unheralded carbon sink champions and a plant’s best friend—the mysterious mycorrhizal fungi.
According to Karst, mycorrhizal fungi—which comes in two types, arbuscular and ectomycorrhizal—colonize the fine root tips of just about every tree and plant on Earth.
In a symbiotic ballet from which life as we know it is allowed to spring, these mycorrhizal fungi grow tiny branch-like hypha into the soil to break down organic matter in a way that roots can’t, taking up nutrients and essentially feeding to the plant.
“A tree could not grow without them,” explained Karst.
While most fungi get their carbon from decomposing matter, Karst said mycorrhizal fungi have given up that ability over time and are completely reliant on a living host to get their carbon supply, which they get through the plant’s sugars
“It is a mutualism, so, yes, they both need each other.”
And while this nutrient transfer from the fungi is what feeds the tree, it’s offering is what makes the headlines these day.
Karst explained those carbon-laden sugars begin as carbon dioxide in the air before it is photosynthesized by the plant.
“Upwards of 40 per cent of those sugars get allocated below ground to support these symbiotes,” she said. “As we learn about mycorrhiza, we learn they affect a lot of ecosystem processes; one of them is carbon cycling.”
Researchers believe that up to 50 per cent of carbon in soils is derived by mycorrhizal fungi.
Karst said she chose to study the aspen because of its wide range and the fact it is the rare species of tree that hosts both ectomycorrhizal and arbuscular mycorrhizal fungi. Because they differ in size and carbon-cycling rates—the larger ectomycorrhizal fungi requires more carbon and leaks more carbon into the soil—she thinks she will be able to determine what is happening to the ecosystem as aspens get stressed and then are lost.
“What I’m interested in is before aspen moves across the landscape, and how a changing environment affects the mycorrhizal community and the cascading effects on ecosystem processes like carbon cycling,” she said. “Typically when we are thinking about roots and microorganisms, we don’t necessarily connect them to these larger scale ecosystem processes. We don’t think of them affecting the forest as whole. There is that avenue of recognizing when we are thinking of forest health, resiliency and productivity—you also have to think these microbes in the soil.
“When you think of the health of the forest, its resiliency and productivity and how it is going to function in the future, we need to recognize that these small things matter.”
A deal announced Monday could mean a $100 million towards solar projects in Texas. Austin-based solar power company PowerFin Partners will develop and build the projects and Toronto-based real estate investors Fengate will finance the deals as part of today’s announced co-development deal.
“Financing of solar projects is pretty difficult,” said Tuan Pham, president of PowerFin. “(The deal) allows Fengate to focus on the financing and us to focus on the operating, development, and construction.”

An open verse to the National Petroleum Council, and who else to include? Please comment below and feel free to forward along to those who could most benefit…
If you’re going to frac, at least, clean up your act.
Have some damn self-respect and consideration
for yourself, children and future generations.
If you want to frac, then clean up your act.
And quit your flaring! It causes people to wheeze,
and at the very least to sneeze violently!
Stop operating so sloppily, as if your business is an old jalopy!
So what if gas is too cheap to capture compared to flare.
When you flare too much methane is released into our atmosphere,
turning, “now we’re cooking with gas”, into being no better than burning coal.
Come on you mental wimp, rise to the challenge, sack up and clean up your act!
Cause the rest of us don’t care to bear the cost of your wasteful operating methods.
So, if not for us, at least for yourself, have some damn self-respect,
and fix your inefficient wasteful plumbing problem of a deficit
that you continue to allow in it’s release of greenhouse gas emissions.
If you want to frac, clean up your act! And quit using
10,000,000 gallons of fresh water to frack one well.
Reuse flowback, clean and recycle wastewater fluids so you won't
need so many disposal wells, that too often cause earthquakes.
Have some self-respect and properly monitor
your well sites and pipelines, and take personal responsibility
to clean up your act, if you wanna frac.
Then you don't have to be crony capitalist exempt,
from the clean air, water and safe drinking water acts.
Otherwise, sooner rather than later, you’ll be disrupted out of business,
with more efficient, cheaper and cleaner renewable sources of energy.
Whale blubber and buggy whips were once fine industries too,
but it didn't take a rocket scientist to say, “who woulda knew”,
that new technology rewards you to move along to better ways,
of doing things these days that help you clean up your act.
So if you want to frac, at least clean up your act
and do something to shut up those damn hippies, treehuggers
and other do-gooders, who not only just want to make this world a better place,
but actually know they can, by getting up off their cans,
and doing something about shutting your dirty-ass industry down.
So if you want to frack, please, clean up your act and become a class act.
Your mother, children and grandchildren will be glad and proud of you that you did.
So if you want to frac clean up your act, asshole, we don’t want our country to become
a shithole country…like 45 likes to talk about and so much despises.
I hope we got my fracs straight, er, uh, I mean facts straight?
You can get confused when things go horizontal, rather than just directional,
and that's just a fraction of it, but you still need to make a correction to your operating methods!
Otherwise, people will continue to make art like this about your industry:

Is it a surprise that Shell has known for years the dangers of fossil fuels? The same goes for ExxonMobil also having known. What should or can be done about it?
A Dutch news organization has published a trove of internal documents from the oil giant Shell showing the company knew about the link between fossil fuel and global warming as far back as the 1980s. Despite their own findings, Shell, like other oil companies, publicly disputed the climate science for decades.
One confidential 1988 report from Shell was titled “The Greenhouse Effect.” It read, “Although CO2 is emitted to the atmosphere through several natural processes … the main cause of increasing CO2 concentrations is considered to be fossil fuel burning.” Friends of the Earth Netherlands is threatening to sue Shell unless it increases efforts to comply with the Paris climate accord. (Shell Knew: Documents Show Oil Giant Hid Dangers of Fossil Fuels for Decades)
This 1988 Shell report, discovered by Jelmer Mommers of De Correspondent, shines light on what the company knew about climate science, its own role in driving global CO2 emissions, the range of potential political and social responses to a warming world.
The confidential report, “The Greenhouse Effect,” was authored by members of Shell’s Greenhouse Effect Working Group and based on a 1986 study, though the document reveals Shell was commissioning “greenhouse effect” reports as early as 1981. Report highlights include:
- A thorough review of climate science literature, including acknowledgement of fossil fuels’ dominant role in driving greenhouse gas emissions. More importantly, Shell quantifies its own products’ contribution to global CO2 emissions.
- A detailed analysis of potential climate impacts, including rising sea levels, ocean acidification, and human migration.
- A discussion of the potential impacts to the fossil fuel sector itself, including legislation, changing public sentiment, and infrastructure vulnerabilities. Shell concludes that active engagement from the energy sector is desirable.
- A cautious response to uncertainty in scientific models, pressing for sincere consideration of solutions even in the face of existing debates.
- A warning to take policy action early, even before major changes are observed to the climate.
In short, by 1988 Shell was not only aware of the potential threats posed by climate change, it was open about its own role in creating the conditions for a warming world. Similar documents by ExxonMobil, oil trade associations, and utility companies have emerged in recent years, though this Shell document is a rare, early, and concrete accounting of climate responsibility by an oil major.
The Alamo City — which was in eighth place last year — now has 161 megawatts of direct current solar power installed, according to the latest Shining Cities report from Environment America. The numbers are through the end of 2017.
Direct current is the power produced by solar panels before being converted to alternating current, which powers homes, and typically is measured at a higher level than AC power due to loss from conversion.
The growth is a 37.6 percent increase over the 117 megawatts of solar that San Antonio had installed by the end of 2016.
“That is the largest growth in the state of Texas in solar and it jumps San Antonio up two places in the rankings from eighth place last year to sixth place this year,” said Luke Metzger, director of the advocacy group Environment Texas, which is part of Environment America.
The latest numbers show San Antonio swapping places with Indianapolis, which had previously been sixth and is now eighth, and pushing past New York City, which San Antonio was ranked just behind last year.
City-owned CPS Energy’s Chief Operating Officer Cris Eugster attributed most of the growth to the utility’s rooftop solar rebate program.
San Francisco and Oakland want to hold fossil fuel companies liable for sea level rise costs. In an unusual move, the judge ordered a climate tutorial for the court.
Judicial review is about to meet peer review in a federal courtroom in San Francisco, where sparring cities and fossil fuel companies have been called to brief U.S. District Judge William Alsup this Wednesday on the basics of climate change.
It's an unusual arrangement, seemingly borrowed from patent litigation, where judges commonly hear initial testimony from both sides on pertinent scientific details.
That's done because the U.S. Supreme Court has directed that the meaning of a patent's words is a matter of law, to be decided by a judge—not a matter of fact to be decided by a jury.
You wouldn't think the science of climate change was like that. No court finding can dictate whether man-made greenhouse gas emissions are warming the planet and causing damage to people, ecosystems and cities. A jury, if this case reaches one, ought to be able to comprehend overwhelming evidence that explains these realities.
We have many ways of measuring methane and CO2 levels. When we measure it we can manage it…if we really want to know and manage it. Polluters can’t hide anymore.
San Antonio’s public utility, CPS Energy, faced blowback from city leaders and environmental groups Thursday on its newly released strategic power plan that takes decades to fully transition to renewable sources of energy.
“A lot of folks felt blindsided by this,” said Russell Seal, a conservation committee co-chair for the Sierra Club’s Alamo Group, outside of City Council chambers before the Thursday meeting with CPS. Seal and a handful of other people showed up to protest the proposal.
The meeting — a regularly scheduled presentation by CPS — came just days after the utility revealed some of its future power-generation planning that assumes the city will continue to rely on coal and natural gas through at least 2040.
Under the “flexible path” plan released Tuesday, solar, wind and other renewable energy would account for half of San Antonio’s power sources by 2040. Gas and coal-fired plants would make up 20 percent of the utility’s power generation by then, with 16 percent coming from a new “flex gen” idea that counts on future technology and power storage.
The utility, which is owned by the city, currently gets roughly 22 percent of its energy from renewable sources, 45 percent from natural gas, 18 percent from coal and 14 percent from nuclear.
“It’s absurd to think that we should have any coal in our energy mix anywhere close to 2042. All coal should be phased out over the next decade if CPS is at all serious about addressing climate change and the impact air pollution has on public health,” Terry Burns, the Sierra Club’s Alamo Group chair, said in an emailed statement. “It is irresponsible and a slap in the face to San Antonio area residents with asthma and other respiratory diseases to continue running Spruce 1 for another 12 years, especially without modern pollution controls.”
The utility’s CEO, Paula Gold-Williams, sought to cool tension at the meeting, assuring City Council members that the plan could change.
“Its not a baked plan that has no flexibility; the operative word is flexible,” Gold-Williams told the council. “Every year we create a look and view of the future based on what we know, and we do multiple updates and thinking and scenarios. That’s planning.”
The plan would shut down CPS’ Spruce 1 coal plant, which went online in 1992, in 2030. The Spruce 2 coal plant, which was completed in 2010 for roughly $1 billion, would run until at least 2042, according to data provided by CPS.
CPS is planning to close the two 1970s-era J.T. Deely coal units at the end of 2018.

CPS Energy’s Future of Energy Symposium shines little light on what’s next for energy mix
San Antonio’s CPS Energy faces criticism on clean energy strategy
District 9 Councilman John Courage asked Gold-Williams why CPS couldn’t just move to 100 percent renewable energy, pointing to the community of Georgetown north of Austin as an example of a city that has made such a commitment.
“That’s a declaration of commitment, and it’s backed up by power agreements in the background that can allocate renewable power fully to cover all the demand and load, which is a viable way to do it,” Gold-Williams said. “But in
reality, power is moving indiscriminately all across the grid all the time, electrons love everybody, and in reality all the power goes in there and they could be getting … like during storms and freezing and there’s no sun and no wind, they’re getting power from other units.”
Power purchase agreements, or PPAs, allow utilities to lock in the generation created by renewable facilities at fixed costs for long periods of times, generally for up to 25 years. CPS Energy uses power purchase agreements signed with multiple companies for most of its wind and solar generation, while it owns its fossil-fuel generation and a stake in a nuclear plant.
Kaiba White, an Austin-based energy policy specialist for Public Citizen, said that power purchase agreements are little different from a utility owning its power generation.
“It kind of hurt me to hear that there’s this idea being perpetuated that Georgetown isn’t doing something real because they don’t own their solar farm,” White said.

Do we have a fundamental right to a climate system capable of sustaining human life?
What’s the point of inheriting the Earth if it’s only going to burn (or drown)?
Kids around the world are asking governments this question and demanding answers in court. For example, on Dec. 11, Juliana v. US pitted the president and American lawmakers against the very children whose future they so often invoke when seeking votes. The kids argued that the government’s negligence in caring for the planet impedes on their rights, and it must remedy this by adopting policies that mitigate climate change.
The case is currently set to go to trial in February. The government is fighting fiercely to dismiss the matter as fast as possible—the Dec. 11 court date was to decide whether the government’s dismissal argument has any merit. But in some senses, whatever happens, it’s already a win for the 21 young Americans who are plaintiffs and their global movement. In bringing the case to the courts, the kids are challenging the world’s most prominent climate change denier, US president Donald Trump. And they are getting a chance to highlight the science that’s being ignored at their expense in the court of public opinion.
Kids v. Feds
Juliana v. US (pdf) was originally filed in an Oregon district court in 2015 by 21 minors from around the country. The youth—now ages 10 to 21—argue that by adopting policies that promote fossil fuel use, leading to the emission of carbon dioxide at rates that change the climate, despite knowing these energy sources are warming the planet, the federal government violates “the youngest generation’s constitutional rights to life, liberty, and property,” and fails to protect essential resources held in trust for the public.
The children say everything is at stake for them. “I hope that the court understands the urgency of the climate crisis and allows our case to proceed to trial,” one plaintiff, 17-year-old Jaime Butler from Flagstaff, Arizona, explained at a press conference last week (pdf). “This case will ultimately determine the livelihood of my tribe, the Navajo Nation, and all native people in this country.”

Elegant design and engineering goes beyond being sustainable to being eco positive. New vocabulary, additional data collection and working with scientists is needed to most effectively stimulate and manage a circular economy, making the means by which we live to be resilient, efficient and productive, and most of all, regenerative and eco positive.
Did you know that most average Americans live as though they have 4.8 planets? This is what Dutch industrial designer Babette Porcelijn discovered when she largely left behind a thriving business working with commercial clients to focus on the hidden impacts of design.
In her research, Porcelijn looks at everything from the global impact of importing and exporting to the environmental toll of producing single consumer items, such as a laptop computer. Her “Impact Top 10” breaks down, with surprising results, the average items used by consumers that cause the largest amount of environmental impact.
Who knew that meat would come in second, beat out only by consumer products, but well above cars? (If you speak Dutch and want to understand your individual impact, answer a few questions to see how you compare to others.)
Excerpts from the interview:
- The sixteen largest container ships emit as much sulfur as all the cars in the world together
- The rich consumer buys a lot of products, but he does not see the impact the production of these goods has on the environment. How can you make sustainable choices if you don't know what’s going on?
- When I started to investigate, I was shocked to find out that often I couldn’t find answers to my questions. Even worse, sometimes there were no words to describe the things I wanted to talk about. The worst finding, perhaps, was the fact that there was no impact top 10 of the average consumer, including hidden impacts.
- If we assess the impact of the consumer, we usually only consider environmental impacts caused by the use of a product. Furthermore, we mainly look at climate effects, but if we solve the climate problem, and we don’t solve problems like water scarcity, pollution or plastic soup, then we still have a problem.
- Over the last few decades, rich consumer countries have moved much of their industry and agriculture to low-wage countries. Production comes with lots of impact on climate, nature, and environment. Rich countries import these products and this food and their consumers buy these. But we often leave the “hidden impact” out of the equation.
- Designers can make a big difference in many ways. First, we are beginning to understand what we should NOT do anymore—and Hidden Impact reveals that thoroughly—but the next question is, what to replace the fulfillment of our needs in a sustainable way? What SHOULD we do? And that is a design challenge! I think we need to work together with scientists to come up with the best solutions.
- We are trained systems thinkers, and the world needs those—product designers can design circular products, and circular business models, while product designers and architects can design for long endurance products, with renewable materials and design for disassembly and reuse.
- We could take responsibility for the products we put in the world; do we want to add more stuff people don’t really need into the world, while it damages the environment and brings our joint future in jeopardy, while the ones who benefit have commercial motives instead of humane motives? Also, design for communication: tell the world what’s at stake and what we can do about it, inspire them with awesome alternatives which are more attractive than our current ways
- In short, we need nothing short of a paradigm shift and we need designers to make it a good one. Eco-positive* and fair.
- The best thing that can happen—and it does, people tell me—is that people actually change their lifestyles. I will never tell people what they should or shouldn’t do. I merely help those who want to make effective changes to improve their environmental impact. And I hope to inspire people as a side-effect of my research.
- Some of the biggest issues you mention, like microplastics, come from items like car tires. With this being such a common item, do you know of any companies working on alternative solutions? ANSWER: It is a common item, but it isn’t common knowledge yet. Nevertheless, I’ve heard about research for better tire materials, but that’s difficult to tackle since biodegradable plastics in nature aren’t as biodegradable as in the lab. We could catch run-off from the roads and clean it, and we could choose a different means of transportation (bike, walk, and public transit).
- We need as many people on board as possible. Especially in rich consumer countries, which have—on average—the biggest impact. In the twelve biggest economies in the world lives 13% of the world population, but we cause 55% of the impact! That means that with 13% of the people, we can reduce over half the impact, and that’s a hopeful thought to me.
- We, consumers, are key. Ultimately, we decide everything that’s going on in the world, even though we often don’t realize it. We buy products and with our money, companies thrive. They can either damage or save the environment, and we get to choose which ones survive by buying their stuff. We decide who our politicians are and what they will fight for. The more money you have, the more difference you can make, either by your lifestyle and daily habits or by devoting yourself as a professional to for an eco-positive society*.
[*Eco positive: when you (or a company, or a city/country etc) have a more positive impact on the environment than negative, harmful impact. Protecting and restoring nature, working on family planning and reducing population growth, designing sustainable or eco-positive solutions, cleaning up pollution etc.]

World’s First Solar Mural Installation, a Land Art Generator Artwork by Cruz Ortiz, to be Unveiled at Luminaria. La Monarca’s final home will be at EPIcenter where it will generate clean energy for the site
SAN ANTONIO, TX –– Land Heritage Institute (LHI), in collaboration with EPIcenter, Local Initiatives Support Corporation (LISC), and the Land Art Generator Initiative (LAGI) have partnered to present the world’s first Solar Mural installation – public art that produces renewable energy.
The Solar Mural artwork, La Monarca, will be unveiled at Luminaria, San Antonio’s 10th annual contemporary arts festival, held at Hemisfair on November 10, 2017. La Monarca’s final home will be at EPIcenter, and it will indeed generate clean energy.
La Monarca will be a spectacular, giant lotería card #24, which celebrates San Antonio’s status as the National Wildlife Federation’s first Monarch Butterfly Champion City.
The image, crafted by San Antonio artist Cruz Ortiz, is printed onto a special film produced by Sistine Solar. The film visually masks the standard dark blue solar cells, replacing them with the beautiful La Monarca image. The film allows light to pass through to the photovoltaic cells beneath and generate electricity.
There will be four panels stacked 2×2 at a vertical angle, measuring 6’6” wide by 11’ tall. Each panel stands at 66” x 40”.
Power from La Monarca will be stored throughout the day and then used to power the lights that will illuminate the artwork during the Luminaria Festival.
Following the close of Luminaria, La Monarca will find a permanent home inside a pollinator garden on the EPIcenter campus along the Mission Reach of the San Antonio River where it will generate solar energy for the facility.
“EPIcenter is a place committed to new energy innovation; we are excited to premiere the world’s first Solar Mural at Luminaria and look forward to enjoying this work of art – and the energy it will produce – at the EPIcenter campus,” said Kimberly M. Britton, Chief Executive Officer.
Partners hope that in the near future, Las Monarcas will be a swarm of Monarch Butterfly-inspired Land Art Generator artworks to be designed for placement at and to provide power to social service centers, municipal buildings, or eco-cultural tourism destinations throughout the City of San Antonio or other stops along Monarch Butterfly migration routes.
LHI will also be hosting the 5th biennial LHI Art-Sci Symposium in partnership with Luminaria in Southtown on Saturday, November 11, 9:30 a.m.-5 p.m. at The Mercury Project (538 Roosevelt Avenue), free and open to the public. Symposium sessions, geared toward a general audience and fine for families with finesse, will focus on Sound Art & Sound Walks, Feminist Art in a Digital Age and reGEN: artists and scientists exploring regenerist practices and renewable energies. For a full agenda please see www.renewableart.org.
At Luminaria, La Monarca will appear atop a grassy knoll between two of the three historic 1960s-era “Confluence of Cultures” murals commissioned for the HemisFair ’68 World's Fair: a stone mural by Juan O’Gorman and a glass tile mural by Carlos Mérida. Luminaria will take place Friday, November 10, 2017 from 7:00 pm to midnight at the Hemisfair campus in downtown San Antonio, TX. (NOTE: The grassy noll is between E. Market St. and the Convention Center.)
La Monarca has been a collaboration between Land Heritage Institute’s LHI Art-Sci Projects, EPIcenter, the Local Initiatives Support Corporation (LISC), and the Land Art Generator Initiative. Fabrication and technical support has been provided by OCI Solar Power, Mission Solar Energy, Sun Action Trackers, and Sistine Solar. The project has been made possible through support from EPIcenter and OCI Solar Power, the Alice Kleberg Reynolds Foundation, the Texas Commission on the Arts, and the National Endowment for the Arts. Learn more at www.monarcas.org.
EPIcenter is flipping the switch on an historic 1909 power plant by transforming it into a world-class center that will be the hub for new energy technology innovation, education and community engagement, and entrepreneurial incubation and ideation. The EPI stands for Energy, Partnerships and Innovation. Learn more at www.epicenterus.org.
The Land Art Generator Initiative (LAGI) delivers sculptural installations that have the added benefit of renewable power generation for individual buildings and/or the utility grid. LAGI artworks provide power to neighborhoods and cities while adding visual interest to outdoor spaces—from public parks and streets to private courtyards.

The wings of a butterfly have inspired a new type of solar cell that can harvest light twice as efficiently as before and could one day improve our solar panels.
Solar panels are usually made of thick solar cells, and are positioned at an angle to get the most amount of light from the sun as it moves throughout the day. Thin film solar cells, which can be only nanometers thick, have a lot of potential. These are cheaper and lighter, but because they’re less efficient, we usually use them only in watches and calculators, instead of solar panels. Scientists studied the black wings of the rose butterfly, and copied the structure to create thin solar cells that are more efficient. Unlike other types of cells, these can absorb a lot of light regardless of the angle, and are also easy to make. The results were published in the journal Science Advances.
The rose butterfly is native to Southeast Asia. Because it is cold-blooded and needs sunlight to fly, its black wings have evolved to be very good at absorbing energy. “The really interesting thing is that the butterflies, which have evolved these complex structures as a result of selection over millions of years, are still way outperforming our engineering,” YaleNUS College biology professor Vinod Saranathan told The Verge in an email. (Saranathan was not involved in the study.)
To figure out why these butterflies are so efficient, scientists led by Radwanul Siddique, a bioengineer at the California Institute of Technology, looked at wings under an electron microscope and created a 3D model of the wings’ nanostructures. The wings are built from tiny scales that are covered in randomly spaced holes. The holes are less than a millionth of a meter wide, and they help scatter the light and help the butterfly absorb heat.
The holes are random in size, distribution, and shape, says Siddique. Using computer models, the team figured out that the position and order are important for absorbing light, but the shape doesn’t matter. Next, they created a similar structure using extremely thin sheets of hydrogenated amorphous silicon that have the same type of holes.
Most solar panels are positioned at an angle, which means they generate lots of power for a few hours and then not much the rest of the time. Solar panels using Siddique’s technique could produce more power throughout the day. Though Siddique is now at CalTech, he did this research as part of his doctoral work in Germany, and some members of his old lab have already received funding from the German Research Foundation to work on solar cells and LEDs.
Renewable energy might be clean, but it's not always reliable if the Sun ducks behind clouds or the wind slacks off. To counter that variability, the grid will need to combine a range of different sources, such as solar, wind, hydro, waves, and biomass, with large-scale energy storage systems. Now, an MIT team has developed a new type of battery that could fit the bill. It breathes air, and can store energy long-term for about a fifth of the cost of existing technologies. The new design is a rechargeable
The new design is a rechargeable flow battery, meaning its cathode and anode components are liquids (catholyte and anolyte) that pass ions back and forth to store or release energy. In this case, the anolyte is made up of sulfur dissolved in water, and the hunt for an equally abundant material for the catholyte led the team to an oxygenated liquid salt solution.
Across the U.S., energy users of all sizes are taking control of their power supply and relieving stress from the grid. That’s the idea behind distributed energy. Atlantic Re:think and Siemens partnered to explore this burgeoning energy revolution in 360º video.
The traditional power grid is under tremendous pressure. In many places, infrastructure needs to be upgraded. Extreme weather and cybersecurity are constant concerns. These challenges threaten entire communities and businesses, from hospital networks to manufacturing plants and university systems. Technology now offers more solutions than early energy pioneers could’ve fathomed as they designed the central grid some 150 years ago. There are now more ways to support and complement the grid than ever before. It’s time to tap into these innovations.
Whether the challenge is energy generation, distribution, storage, or management, all can be addressed through a single solution: on-site energy control. Often called distributed energy, this increases reliability while reducing costs and environmental impact. The Siemens portfolio of on-site energy solutions offers users greater control over their energy supply, where it comes from, how sustainable it is, how they use it, and how much they pay for it. It allows them to restore customer and grid power during a complete blackout, and it plays an integral role in the grid’s digital transformation. The technologies are being implemented in new as well as legacy systems, as Siemens helps decision makers across the country to navigate the unique challenges they face. It’s time to take advantage of this technology and overhaul the system; to develop a more economically and environmentally resilient and sustainable approach to how we power our lives.
Members of a local energy-efficiency initiative collectively reduced their carbon impact by more than 10,200 metric tons of carbon dioxide in 2016, according to an annual report from San Antonio 2030 District, which is leading the effort.
The initiative, led mostly by private-sector businesses such as downtown building owners, aims to achieve a 50% reduction in energy consumption by 2030.
Addressing district members last week, SA 2030 District Director Elizabeth Kertesz said that the group’s members together recorded a 22% drop in energy use intensity (EUI). The district uses the EPA’s Energy Star Portfolio Manager as a measurement tool.
