As the New York debate over natural gas builds, experts from Environmental Defense Fund today filed comments in a state proceeding aimed at overhauling gas utility planning in an effort to help the state shift away from fossil fuels and toward cleaner energy sources. EDF’s filing includes a first-of-its-kind greenhouse gas emissions lifecycle tool developed with MJ Bradley & Associates, an ERM Group Company, that gives the New York Public Service Commission, or PSC, and utilities the data they need to align business plans with the state’s climate goals.
New research shows that the global models used to project how Earth’s climate will change in the future underestimate the impact of forest fires and drying climate on forests’ ability to capture and store atmospheric carbon.
Microplastic pollution has been building up in the Great Lakes for at least four decades, but our understanding of its impact on fish and other aquatic creatures is only just catching up.
Now new research from the University of Toronto shows its harm to wildlife is due to a wide range of factors that is not generally considered in toxicology testing — the plastics’ size, shape and chemical makeup.
University of Illinois graphic design professor Lisa Mercer co-developed Racism Untaught, a framework that uses the design research process to explore issues of racism and other forms of oppression. She uses the framework in her classroom and in workshops for universities and corporations to identify design that perpetuates racism.
A graphic design professor at the University of Illinois Urbana-Champaign is using the design research process to explore issues of race and racism.
Lisa Mercer co-developed the framework Racism Untaught with Terresa Moses, a graphic design professor at the University of Minnesota. They use it in the classroom and in workshops in higher education and the corporate world to help identify design that perpetuates racism and find ways to solve problems through anti-racism projects. They developed the toolkit more than three years ago but demand has increased significantly in the past year and a half, particularly after the Black Lives Matter protests last summer.
Mercer and Moses were looking for ways to have meaningful conversations about race, diversity and inclusion.
“People need to lean into these difficult conversations, and we’re creating space to have the opportunity for these conversations,” Mercer said.
She and Moses have led several workshops for faculty members and staff at Illinois and at other universities, as well as for corporations – including the training of high-level managers at a national retailer to run a workshop for 600 product designers.
“We were looking to see if what we do in academia applies in industry. What we’ve found is this applies really well,” Mercer said.
The workshops – which recently have taken place on Zoom – start with building context by looking at a specific situation given as a prompt. Participants are asked to identify elements of racism in the prompt. They could be experiences (a racial slur), artifacts (use of a degrading, stereotypical image) or systems (a disciplinary code that more heavily penalizes people of color).
The prompts come from experiences described in surveys of the university campuses participating in the workshops or examples from industry. Mercer identifies as a mixed-race Latinx woman and Moses as a Black woman, and they have used some of their own experiences as prompts. For example, Mercer has been questioned about her language and heritage.
Some of the prompts used in Racism Untaught include racist branding for pancake mix; a skin cream ad that promotes and encourages lighter skin; and the public highway system designs of urban architect Robert Moses, which specified bridges over highways into certain areas of New York City be built too low for public buses, effectively excluding passengers – primarily people of color – from those areas.
Participants also consider how the problems exist at an individual, institutional or cultural level. Then they come up with ideas to re-imagine the racialized prompt and be agents of change, and they test those ideas for their impact and any unintentional consequences.
Mercer has used the Racism Untaught framework in her design classes. One student project was a board game, Life’s a Bridge, that uses the Moses architecture example to teach about power and privilege in society. Another student developed a campaign called “Just Say Hi” to help people understand why questions about a person’s race or ethnicity, language or sexuality can be insulting.
“If students are really given the space to analyze this, they start to understand the systems in place that uphold these levels of oppression. That is typically my favorite conversation with students,” Mercer said.
She and Moses are expanding the framework to add information about sexism, and they hope to include ableism next.
“We have been very deliberate in holding space for conversations on race and racism before we include other forms of oppression. We have begun adding prompts focused on sexism and ableism to work toward an intersectional conversation on oppression. The ultimate goal is to extend the framework to include homophobia, transphobia, cissexism, gender binary, ageism and other forms of oppression,” Mercer said.
She would like to create a class using the Racism Untaught framework that meets the U. of I.’s general education requirements to reach students from disciplines across campus. A graduate student is translating the framework into Spanish.
“We’d also like to make it more accessible, not just for people in academia or industry who have money, but to grassroots community organizers who need tools to create anti-racist design,” Mercer said.
Mercer and Moses will present a Racism Untaught workshop in June at the National Conference on Race and Ethnicity.
The goal of the Re-Wind Network is to compare sustainable end–of–life (EOL) repuposing and recycling strategies for composite material wind turbine blades.
Research is being conducted four areas:
Wind Energy and Society,
Design for the Built Environment,
Structural Mechanics, and
Geographic Information System (GIS).
The objective of this research is to develop a methodology for use by relevant stakeholders, which include national and local energy and waste management policy makers, wind energy company executives, wind turbine manufacturers, and installers and community members.
The network is a partnership between Georgia Tech, Queen’s University Belfast, The City University of New York, and University College Cork (Ireland). It’s funded by Investi/Department for the Economy, Science Foundation Ireland, and the U.S. National Science Foundation.
As engineers working on climate-smart solutions, we’ve found an easy win-win for both water and climate in California with what we call the “solar canal solution.” About 4,000 miles of canals transport water to some 35 million Californians and 5.7 million acres of farmland across the state. Covering these canals with solar panels would reduce evaporation of precious water – one of California’s most critical resources – and help meet the state’s renewable energy goals, while also saving money.
Conserving water and land
California is prone to drought, and water is a constant concern. Now, the changing climate is bringing hotter, drier weather.
Most of California’s rain and snow falls north of Sacramento during the winter, while 80% of its water use occurs in Southern California, mostly in summer. That’s why canals snake across the state – it’s the largest such system in the world. We estimate that about 1%-2% of the water they carry is lost to evaporation under the hot California sun.
In a recent study, we showed that covering all 4,000 miles of California’s canals with solar panels would save more than 65 billion gallons of water annually by reducing evaporation. That’s enough to irrigate 50,000 acres of farmland or meet the residential water needs of more than 2 million people. By concentrating solar installations on land that is already being used, instead of building them on undeveloped land, this approach would help California meet its sustainable management goals for both water and land resources.
Shading California’s canals with solar panels would generate substantial amounts of electricity. Our estimates show that it could provide some 13 gigawatts of renewable energy capacity, which is about half of the new sources the state needs to add to meet its clean electricity goals: 60% from carbon-free sources by 2030 and 100% renewable by 2045.
Installing solar panels over the canals makes both systems more efficient. The solar panels would reduce evaporation from the canals, especially during hot California summers. And because water heats up more slowly than land, the canal water flowing beneath the panels could cool them by 10 F, boosting production of electricity by up to 3%.
These panels could also generate electricity locally in many parts of California, lowering both transmission losses and costs for consumers. Combining solar power with battery storage can help build microgrids in rural areas and underserved communities, making the power system more efficient and resilient. This would mitigate the risk of power losses due to extreme weather, human error and wildfires.
We estimate that the cost to span canals with solar panels is higher than building ground-mounted systems. But when we added in some of the co-benefits, such as avoided land costs, water savings, aquatic weed mitigation and enhanced PV efficiency, we found that solar canals were a better investment and provided electricity that cost less over the life of the solar installations.
Benefits to the land
Solar canals are about much more than just generating renewable energy and saving water. Building these long, thin solar arrays could prevent more than 80,000 acres of farmland or natural habitat from being converted for solar farms.
Yet another benefit would be curbing aquatic weeds that choke canals. In India, where developers have been building solar canals since 2014, shade from the panels limits growth of weeds that block drains and restrict water flow.
Fighting these weeds with herbicide and mechanical equipment is expensive, and herbicides threaten human health and the environment. For large, 100-foot-wide canals in California, we estimate that shading canals would save about US$40,000 per mile. Statewide, savings could reach $69 million per year.
Bringing solar canals to California
While India has built solar arrays over canals and the U.S. is developing floating solar projects, California lacks prototypes to study locally.
Discussions are underway for both large and small demonstration projects in the Central Valley and Southern California. Building prototypes would help operators, developers and regulators refine designs, assess environmental impacts, measure project costs and benefits, and evaluate how these systems perform. With more data, planners can map out strategies for extending solar canals statewide, and potentially across the West.
It will take a dozen or more partners to plan, fund and carry out a solar canal project in California. Public-private partnerships will likely include federal, state and local government agencies, project developers and university researchers.
California’s aging power infrastructure has contributed to catastrophic wildfires and multi-day outages. Building smart solar developments on canals and other disturbed land can make power and water infrastructure more resilient while saving water, reducing costs and helping to fight climate change. We believe it’s a model that should be considered across the country – and the planet.
When a meteorologist says that a chilly day in May was 12 degrees lower than normal, the normal being referenced is typically from the official 30-year U.S. Climate Normals. Updated every decade, the Normals are based on 30-year averages of climate observations recorded at thousands of weather stations across the country.
On May 4, the 1991-2020 U.S. Climate Normals are being released by the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information (NCEI). In conjunction, the University of Nebraska–Lincoln’s High Plains Regional Climate Center is publishing a new tool that allows users to examine what normal looks like relative to longer or shorter timeframes than the most recent 30 years.
