The nation's largest public power company, the Tennessee Valley Authority, is offering its energy expertise to University of Tennessee students hoping to get a leg up in an international competition to make the most appealing and energy-efficient house.

The 850-square-foot house packed with energy-efficient appliances and a cutting-edge automated system to control lighting and electricity will be on display on the National Mall in Washington, D.C., next summer. It will compete against entries of 19 other teams that made it to the final round of the competition.

The team with the most creative, marketable and efficient house will win the 2011 Department of Energy's Solar Decathlon, an event held every other year.

For UT, it's an opportunity to showcase the state's commitment to renewable energy research and industry, including recent solar partnerships between the state and the university. For TVA, it's a chance to benefit from the research and contribute to a better work force for the utility in the future.

TVA has "been instrumental in advising us and really being an open-book resource to us on their lessons learned from past projects and a wealth of knowledge in home design," said Amy Howard, the project manager and a recent graduate of the master's of architecture program.

She said TVA also will likely be part of a statewide tour of the house that will include education on how conservation can save families money.

Finding sources of renewable power and power from clean sources — along with helping families lower their monthly bills — are all part of the renewed mission of TVA, said spokesman Mike Bradley.

"They're after the same things we are, and we're really pleased to be part of the project," said Bradley. "We are looking at some of the challenges and getting involved in some of the solutions with students in the competition to provide expertise. It will help up develop a workforce for future engineers who will hopefully work for TVA."

The team includes students from the colleges of Architecture and Design, Engineering, and Arts and Sciences and local business partners who are offering sponsorships, materials and expert advice.

The team built a 250-square-foot prototype after raising $50,000 in support on its own. Now it will build the full-scale house in a warehouse off Middlebrook Pike and then assemble it on the National Mall this summer.

UT's entry has been dubbed the "Living Light House" and will cost between $350,000 to $400,000.

The project will hopefully lead to stronger partnerships and perhaps new projects with the different companies and industries involved and can also be used as a recruiting tool for the university, Howard said.

But mostly, she said, she hopes to bring recognition to the state.

"It brings a lot of attention to the state of Tennessee, and we have partners on board willing to help us and interested in the research and topics we're interested in," she said.

"That makes a statement about Tennessee, and with our goals for solar energy and other energy efficiencies, it's important for us to be a part of this research and get information out there and spread the word and inform and educate our fellow Tennesseans."

National Energy Board hears oral traditional evidence over Manitoba-Minnesota transmission line

Manitoba-Minnesota Transmission Line connects Bipole III to Minnesota, raising export capacity, as NEB hearings weigh Indigenous rights, treaty obligations, environmental assessment, cumulative effects, and cross-border hydroelectric infrastructure impacts, land access, socio-economic concerns, and regulatory review.

 

Key Points

A cross-border hydro line linking Manitoba to Minnesota under review on Indigenous rights and environment concerns.

✅ Connects Bipole III to Minnesota to boost exports

✅ NEB hearings include Indigenous rights and treaty issues

✅ Environmental and access impacts debated in regulatory review

 

Concerned Indigenous groups asked the National Energy Board this week to take into consideration existing and future impacts and treaty rights, which have prompted a halt to Site C work elsewhere, when considering whether to OK a new hydro transmission line between Manitoba and Minnesota.

Friday was the last day of the oral traditional evidence hearings in Winnipeg on Manitoba Hydro's Manitoba-Minnesota Transmission project.

The international project will connect Manitoba Hydro's Bipole III transmission line to Minnesota and increase the province's electricity export capacity to 3185 MW from 2300 MW.

During the hearings Indigenous groups brought forward concerns and evidence of environmental degradation, echoing Site C dam opponents in other regions, and restricted access to traditional lands.

Ramona Neckoway, a member of the Nelson House First Nation, talked about her concern about the scope of Manitoba Hydro's application to the NEB.

"It's only concerned with a narrow 213 km corridor and thus it erases the histories, socio-economic impacts and the environmental degradation attached to this energy source," said Neckoway.

Prior to the hearings the board stated it did not intend to assess the environmental and socio-economic impacts of upstream or downstream facilities associated with electricity production, even as a utilities watchdog on Site C stability raised questions elsewhere.

However, the board did hear evidence from upstream and downstream affected communities despite objection from Manitoba Hydro lawyers.

"Manitoba Hydro objected to us being here, saying that we are irrelevant, but we are not irrelevant," said Elder Tommy Monias from Cross Lake First Nation.

Manitoba Hydro representative Bruce Owen said, "We respect the NEB hearing process and look forward to the input of all interested parties."

The hearings provided a rare opportunity for First Nations communities, similar to Ontario First Nations urging action, to voice their concerns about the line on a federal level.

"One of the hopes is that this project can't be built until a system-wide assessment is made," said Dr. Peter Kulchyski, an expert witness for the southern chiefs organization and professor of Native Studies at the University of Manitoba.

 

Hearings continue

The line is already under construction on the American side of the border as the NEB public hearings continue until June 22 with cross examinations and final arguments from Manitoba Hydro and intervenor groups.

The NEB's final decision on the Manitoba-Minnesota transmission line, amid an energy board delay recommendation, will be made before March 2019.

More than Two-thirds of Americans Indicate Willingness to Give or Donate Part of their Income in Support of the Fight Against Climate Change

U.S. Climate Change Donation Survey reveals Americans' willingness to fund sustainability via government incentives, electrification, and renewable energy. Public opinion favors wind, solar, and decarbonization, highlighting policy support post-pandemic amid economic recovery efforts.

 

Key Points

A 2020 U.S. poll on climate attitudes: donation willingness, renewable support, and views on government incentives.

✅ 70% would donate income; 31% would donate nothing.

✅ 59% prefer government incentives; 47% support taxes, conservation.

✅ 85% land wind, 83% offshore wind, 90% solar support.

 

A new study of American consumers' attitudes toward climate change finds that more than two-thirds of respondents (70%) indicate their willingness to give or donate a percentage of their personal income to support the fight against climate change and the path to net-zero electricity emissions by mid-century. 

Twenty-eight percent indicated they were willing to provide less than 1% of their income; 33% said they would be willing to contribute 1-5% of their income; 6% said they would give between 6-10% of their income; and 3% indicated they would contribute more than 10% of their income. Just under one-third (31%) of those surveyed indicated they were unwilling to give or donate any percentage of their income to support the fight against climate change.

The U.S. findings are part of a series of surveys commissioned by Nexans in the U.S., UK and France, in order to determine public opinion on climate change and related issues in the wake of the COVID-19 pandemic. The U.S. study was conducted online by Researchscape from August 20 – 24, 2020. It had 1,013 respondents, ages 18 or older, with the results weighted to be representative of the overall population (variables available upon request).

Nexans, is headquartered in Paris with a major offshore wind cable manufacturing facility in Charleston, S.C. and an industrial cable manufacturing facility in El Dorado, Ark. The company is fully committed to fighting climate change and is helping to make sustainable electrification possible. The survey was developed as part of its celebration of the first Climate Day in Paris which included a roundtable event with world-renowned experts, the release of an unprecedented global study by Roland Berger on the challenges raised by the electrification of the world, the question of whether the global energy transition is on track, and Nexans' own commitment to be carbon neutral by 2030.

Paying the Tab to Address Climate Change

Participants were given the opportunity to choose from seven multiple responses to the question "How should the fight against climate change be paid for?" The majority (59%) replied it should be paid for by "government incentives for both businesses and consumers." It was followed by "federal, state and/or local taxes" and "conservation programs" (tied at 47%); "business investments" (42%), such as carbon-free electricity initiatives, and "consumer-driven purchases" (33%). Just 9% selected none of the above and 2% selected other.

"Through the organization of this Climate Day, Nexans is asserting itself not only as an actor but also a thought leader of the energy transition for a sustainable electrification of the world. This electrification raises a number of challenges and paradoxes that must be overcome. And it will only happen with the direct involvement of the populations concerned. These surveys provide a better understanding of the level of information and disinformation, including climate change denial, in public opinion as well as their level of acceptability of these lifestyle changes," said Christopher Guérin, CEO, Nexans.

Among other findings, 44% are dissatisfied with the job that federal and state governments are doing to address climate change, while utilities like Duke Energy face investor pressure to release climate reports, 35% are somewhat satisfied and 21% are either very satisfied or completed satisfied with government's role.

Americans expressed overwhelmingly favorable views of wind and solar renewable energy proposals, as carbon emissions fall when electricity producers move away from coal. Specifically, 85% stated being in favor of wind turbines on land (15% against), 83% in favor of wind turbines off the coast (17% against) and 90% in support of solar panel farms (10% opposed).

Those surveyed were asked about their current and changing priorities towards climate change as influenced by the coronavirus pandemic and impacts like extreme heat on electricity bills. Thirty-nine percent indicated that climate change was no more and no less a priority due to the current health emergency; just under a third (31%) indicated that climate change is more of a priority while 30% said it was less of a priority.

In similar research conducted by Nexans in the United Kingdom, nearly two thirds (65.8%) of UK respondents said they would be willing to donate part of their salary to fight climate change. Furthermore, nearly a third (29%) of the UK's consumers believe that combating climate change has become more of a priority in light of the coronavirus pandemic. The UK research was conducted online by Savanta from August 21 – 24, 2020. A total of 2210 respondents, aged 16 and above, representative of the UK population took part.
